The Westernmost Town in Our Territory — and the One That Gets Hit First
We’re the Wilborn family. Women-led, family-owned, working out of our Route 176 office in Crystal Lake since 2005. Marengo sits at the far western edge of McHenry County — about 25 minutes from our office via IL-176, past Union, through the farmland that opens up once you leave the Crystal Lake corridor behind. I’ve been driving Route 20 through Marengo for two decades, passing the historic buildings along E. Prairie Street, crossing the Kishwaukee River bridge, watching how the open agricultural landscape on the west side of town funnels storm systems straight into those first rows of homes without a single windbreak to slow them down. Marengo is a town of roughly 7,000 people, 2,898 housing units, and a median home value of $229,900 — the most affordable market in our entire service area. That affordability means every dollar spent on siding has to work harder here than it does in Barrington or Lake Zurich. And that’s exactly why material selection matters more in Marengo than almost anywhere else we work.
The Kishwaukee River cuts through this town and creates a moisture corridor that most Marengo homeowners never think about until they pull a panel off their wall and find what’s growing behind it. The river is not a scenic detail. It pumps humidity into the surrounding housing stock from April through November, softening sheathing, feeding mold colonies, and accelerating the deterioration of every moisture-vulnerable material on the exterior. I’ve inspected homes in the Historic Downtown grid — structures pushing 120, 150 years old — where three generations of siding materials sat stacked on top of each other, each one trapping moisture against the one below it. Original wood clapboard under aluminum under vinyl. The homeowner thought the house looked fine. The sheathing told a different story entirely.
Then factor in the storm exposure. Marengo is the closest IHC territory city to the Rockford severe weather corridor. Flat terrain, open farmland on three sides, no tree canopy buffer to knock down wind speed before it reaches residential neighborhoods. The July 2024 derecho sent 60 to 100 mph winds across western McHenry County. August 2025 brought three consecutive days of severe storms with 60 to 70 mph gusts and hail. April 2026 collapsed a home in McHenry County and dropped trees across roadways near Marengo. And in 2015, a tornado tracked along Route 20 near Johnson Road and stopped short of Marengo — close enough that residents still talk about it a decade later. If your siding has survived the last three storm seasons without visible damage, I’d still want to check behind the panels. Hail fractures vinyl in ways you cannot see from the driveway, and those hairline cracks turn into moisture pathways all winter long.
Siding Options for Marengo Homes — Side by Side
Current IHC installed pricing for Marengo. Material choice depends on proximity to the Kishwaukee River, age of your home, storm exposure from the open farmland to the west, and how long you plan to stay.
| Material | Per Sq Ft Installed | Lifespan | Warranty | Best For (Marengo) |
|---|---|---|---|---|
| James Hardie | $12 – $16 | 50+ years | 30-year non-prorated | Kishwaukee River corridor homes, Historic Downtown properties, any structure within 1/4 mile of the river |
| LP SmartSide | $12 – $16 | 30–50 years | 5/50 substrate + finish | Deerpass ranches, Indian Trails villas — deep wood-grain aesthetic at fiber-cement-level durability |
| Premium Vinyl | $8 – $10 | 20–30 years | Lifetime limited | South/East expansion homes on higher ground, set back from the river, budget-conscious first-time owners |
| Cedar, Stained | $16 – $22 | 25–40 yrs (with maintenance) | Varies | Landmarked historic homes where the Preservation Commission requires architectural fidelity to the original exterior |
Hardie and LP SmartSide carry identical installed pricing in Marengo. The decision hinges on texture preference, Kishwaukee River proximity, and whether you’re matching an existing aesthetic or starting fresh. In a town surrounded by open farmland with a river running through it, we push hard toward moisture-proof materials. See our full siding cost guide →
Open Farmland, a River, and the Rockford Storm Corridor — Marengo’s Siding Takes a Beating
Most McHenry County towns have trees, subdivisions, and commercial corridors that absorb wind energy before it reaches residential walls. Marengo has open agricultural land on the west, north, and south. Storms rolling east from Rockford hit Marengo at full intensity because there is nothing between the flat prairie and the first row of houses along Route 20. That geographic reality is not something a marketing brochure will tell you, but it’s something your siding experiences every single storm season. West-facing walls on homes along W. Grant Highway and the post-war neighborhoods east of downtown take the brunt of every system that moves through. I’ve seen vinyl panels ripped clean off west-facing elevations on homes where the east side looked untouched.
The numbers tell the story. Illinois set a record with 142 tornadoes in 2024 alone. The July 2024 derecho produced 32 tornadoes across the Chicago metro area with winds reaching 100 mph. An EF-0 tornado tracked near Harvard — 15 miles north of Marengo — in May 2024, accompanied by 2.1-inch hail. April 2023 dropped ping-pong-ball-sized hail, 1.5 inches in diameter, across McHenry County. August 2025 delivered three straight days of severe storms with 60 to 70 mph winds. And April 2026 brought thunderstorms with 50 to 60 mph gusts that collapsed a home in the county. Marengo caught some piece of every single one of those events. Western McHenry County gets the leading edge of storm systems, and Marengo, as the westernmost city in our territory, gets hit before Crystal Lake, before Woodstock, before anyone else.
Layer the Kishwaukee River on top of that storm exposure. The river defines Marengo’s western geography, creates flood zones through the center of town, and serves as the primary storm drainage for the entire city. That river corridor pumps sustained humidity into the surrounding air from spring through late fall. Homes near the Kishwaukee — the lots backing up to the river west of the downtown grid, the properties near Indian Oaks Trail, the older homes along Route 23 where it crosses the water — sit in a microclimate that shortens siding lifespan by 20 to 30 percent versus homes on higher ground in the South/East expansion areas. Combine river humidity, a 90-degree annual temperature swing, dozens of freeze-thaw cycles between November and March, and storm systems arriving at full prairie intensity, and you get an exterior environment that punishes anything short of premium materials.
Builder-grade vinyl rated for 25 years fails at 16 or 17 on a Marengo lot near the Kishwaukee. Cedar without a disciplined staining schedule every 3 to 5 years rots out in 12 years instead of 25. Fiber cement and engineered wood are the two material classes whose warranties actually survive what this town throws at a wall.

James Hardie Fiber Cement Siding →
HardiePlank lap siding, HardieShingle shake panels, HardiePanel vertical board, and HardieTrim — installed as a matched system with every component sealed and integrated. On a Kishwaukee River corridor home in Marengo, Hardie is the material that makes sense 9 times out of 10. Fiber cement cannot absorb moisture. It will not rot, swell, or delaminate in the sustained humidity the Kishwaukee pumps into the surrounding air eight months of the year. The ColorPlus factory finish is baked at 400 degrees Fahrenheit — not brushed on in a driveway — and holds color where site-painted wood fails in 3 to 5 years under Marengo’s moisture and UV load. As a James Hardie Preferred Remodeler, we deliver the full 30-year non-prorated warranty that a non-preferred installer cannot offer even if they hang the exact same planks. On a $229,900 Marengo home, that warranty distinction protects a significant portion of the home’s total value.

LP SmartSide Engineered Wood Siding →
LP SmartSide infuses every strand of engineered wood substrate with the SmartGuard process — zinc borate and resin driven through the entire panel, not applied as a surface treatment. That strand-level protection is the reason SmartSide outperforms natural wood in a town where ambient humidity stays elevated thanks to the Kishwaukee River. SmartSide resists moisture infiltration, fungal decay, and termite damage — the three failure modes that destroy natural wood siding on homes in the post-war neighborhoods, along W. Grant Highway, and throughout the Historic Downtown grid. Priced identically to Hardie per square foot installed. Deeper, more realistic wood-grain texture. LP’s 5/50-year limited warranty. We hold LP SmartSide Preferred Installer status. For Marengo homeowners in Indian Trails or Deerpass who want a warm wood aesthetic without repainting every 5 years, SmartSide delivers exactly that.

Premium Vinyl Siding →
I’ll be straight with you about vinyl in Marengo. This town has river humidity on one side and open-prairie wind exposure on the other. Premium vinyl (0.044″ to 0.046″ panel thickness) performs adequately on newer South/East expansion homes built on higher ground, away from the Kishwaukee, with modern house wrap and proper flashing. But if your home sits anywhere near the river corridor, in the post-war neighborhoods, or along the Historic Downtown grid where structures are 70 to 180 years old — vinyl is the wrong material. Period. The sustained humidity accelerates seal lock failure. Once those locks release, water gets behind the panels and you won’t know until the sheathing is soft. I will tell you that honestly before we write a proposal, even if it means recommending a more expensive product.
Vinyl-to-Fiber-Cement Conversion
This is the single most common siding project we run in Marengo right now. Post-war ranches east of downtown with builder-grade vinyl from the 1990s. Deerpass homes approaching 30 years old with faded, brittle panels. Historic Downtown properties where 30-year-old vinyl was nailed over aluminum that was nailed over original wood clapboard from the 1890s. We tear every layer off, inspect and repair the sheathing — on homes within a quarter mile of the Kishwaukee, there is almost always moisture damage at the bottom two courses — install new weather-resistive barrier with fully taped seams, and re-side in Hardie or SmartSide. A typical Marengo vinyl-to-fiber-cement conversion runs 7 to 12 working days depending on how many layers we strip, how much sheathing repair is needed, and whether trim complexity on an older home adds time.
Soffit, Fascia & Trim →
On Kishwaukee River corridor homes, the soffit and fascia typically fail before the field siding does. River humidity holds moisture against roofline components, rots fascia boards from the backside, peels soffit paint, and opens entry points for carpenter bees and woodpeckers. This pattern is especially severe on the Historic Downtown homes where original fascia boards are 100+ years old and have been painted over a dozen times without ever being replaced. We replace soffit and fascia in aluminum or HardieTrim, wrap every window and door casing, and seal every transition point. Patching one rotted section while leaving the rest alone is a waste of money — moisture finds the unsealed joint within two seasons in this humidity.
Storm Damage Siding Repair →
Hail-cracked vinyl, wind-ripped panels, tree-limb punctures. After the August 2025 storms that brought 60 to 70 mph winds and hail to western McHenry County over three consecutive days, we documented siding damage across Marengo’s post-war neighborhoods, the Historic Downtown core, and homes along Route 20 and Route 23. If your siding took hail impact and you have not filed a claim, the damage is still there and every freeze-thaw cycle is making it worse. Our sister company, IHC Public Adjusters — a separately licensed Illinois public adjusting firm — handles siding damage claims from initial documentation through final payment, including supplement negotiation when the carrier’s first check falls short (financial relationship disclosed per 215 ILCS 5/1575).
Our Marengo Siding Replacement Process
Pin Meter First, Sales Pitch Never
Every Marengo siding inspection starts with a moisture probe, not a brochure. The pin meter goes into the sheathing behind suspect panels on every elevation. In a town built along the Kishwaukee River, visible condition tells you almost nothing about what’s happening behind the panels. I’ve pulled siding off homes near Route 23 at the river crossing that looked perfectly fine from the curb — and found sheathing registering 28% moisture content. On the Historic Downtown homes along E. Prairie Street and the original grid, the inspection also checks for layered materials: clapboard under aluminum under vinyl, each generation holding moisture against the one below it. For any property on the Marengo Historic Preservation Commission’s list of 14 landmarked buildings, I flag the need for exterior review before writing a proposal. The assessment is free and takes about 90 minutes for a typical Marengo home.
Physical Samples, Written Numbers, No Guesswork
I bring cutaway samples of Hardie fiber cement, LP SmartSide engineered wood, and premium vinyl to your kitchen table so you can hold each one, feel the weight difference, and see how the color and texture sit against your existing brick, stone, or trim. The written estimate breaks down every cost line by line: product per square foot, labor, new weather-resistive barrier, HardieTrim or SmartSide trim, flashing at every window and door, Marengo building permit, dumpster, and haul-away. Your lot and your proximity to the Kishwaukee dictate the material recommendation. A river-corridor property gets fiber cement. A newer South/East expansion home on high ground might be a candidate for premium vinyl depending on elevation and wind exposure.
132 E. Prairie Street — We Handle the Permit
Siding replacement in Marengo requires a building permit submitted through City Hall at 132 E. Prairie Street. The city follows standard McHenry County building codes. We file the application, coordinate the inspection window around installation progress, and close the permit when the building department signs off. If the property sits within a historic overlay district or involves one of the 14 landmarked buildings maintained by the Marengo Historic Preservation Commission, we handle that review process as well. The entire permitting burden sits on our plate. Your only job is choosing the color.
Strip, Repair, Wrap, Install, Walk Through
Every panel comes off. On Kishwaukee River corridor homes and the older lots in the Historic Downtown grid, we typically find sheathing damage at the bottom two courses where humidity has been wicking upward for decades. Damaged sheathing gets replaced before anything else goes on the wall. New weather-resistive barrier with fully taped seams. Flashings integrated at every window head, door jamb, and roof-to-wall intersection. Kick-out flashing at every junction where a roof plane meets a sidewall — the single most overlooked leak point on homes with this kind of moisture exposure. Our W-2 crew installs to manufacturer spec, wraps every window and door casing, and walks you through the finished product elevation by elevation before handing over warranty documentation.
The Kishwaukee River Is Working Against Your Siding Right Now
Most Marengo homeowners don’t realize their siding has a moisture problem until the sheathing behind it is already compromised. A pin meter tells the truth in five minutes. We bring one to every inspection, and the inspection costs nothing. Builder-grade vinyl from the post-war era, faded panels on a Deerpass ranch, layered materials on a Historic Downtown Victorian — whatever the situation, you get a straight answer and a written proposal with every cost line visible. Marengo is the most affordable market in our territory, and we respect that by never recommending more material than the home actually needs.

Why Marengo Homeowners Choose IHC for Siding
Two Certifications That Determine Your Warranty Coverage
James Hardie Preferred Remodeler. LP SmartSide Preferred Installer. Each requires documented installation quality, field audits, and ongoing performance reviews. The practical result is simple: when we hang HardiePlank on a Marengo home, the 30-year non-prorated warranty attaches because Hardie verified our work meets their standard. A contractor without Preferred status installs the same plank and delivers a lesser warranty that covers less, for fewer years. On a home taking river humidity and open-prairie wind on alternating elevations, that warranty gap is not a technicality. It’s the difference between a covered repair in year 18 and a $6,000 bill you pay yourself.
Marengo Was Founded in 1835. We’ve Been at the Same Office Since 2005.
Calvin Spencer settled what became Pleasant Grove almost 200 years ago. The town was renamed Marengo after Napoleon’s 1800 victory in Italy, and that sense of durability runs through the community. We run on the same principle. Same family, same Route 176 office in Crystal Lake, same phone number for 21 years. Siding warranties stretch 30 to 50 years. The contractor who installed the product needs to exist for that entire span. Storm chasers who showed up in western McHenry County after August 2025 will be in a different state by next spring. Our office is 25 minutes from Marengo via IL-176, and it’ll be there when your Hardie warranty is still active in 2056.
Family-Operated, Women-Led, McHenry County Rooted
The Wilborns built this company from one Crystal Lake location and never left. Women-led from the ownership level — that’s how the business operates, not something we slap on a truck for marketing points. Marengo is a town where reputation moves fast — 7,000 people, Settler’s Days every year, Marengo Community High School on Friday nights. When you call (815) 356-9020, you reach someone in McHenry County who has driven Route 20 through your town hundreds of times and can talk about your project without transferring you to a call center or reading from a telemarketer script.
One Permit, One Crew, Every Exterior Surface
August 2025 didn’t damage just siding. It hit roofs, gutters, windows, soffit, fascia, and trim on the same Marengo homes simultaneously. Hiring three separate trades means three permit applications through 132 E. Prairie Street, three dumpsters in your driveway, and three warranty holders pointing at each other when something doesn’t line up at a transition point. We scope the full building envelope under one Marengo permit and execute with our own crew on a single coordinated timeline. One phone number. One company accountable for every surface. We also bring InnoMAXX and F-Wave synthetic options to the table when the project calls for performance beyond standard materials.
Carrier Underpayment Is Standard Practice — Not a Fluke
The first check from your insurance carrier after the August 2025 storms typically covered the roof and ignored the siding, gutters, and trim damage visible on every elevation. Our sister company, IHC Public Adjusters, is a separately licensed Illinois public adjusting firm that files supplements with line-item Xactimate documentation until the settlement reflects the actual repair cost for your Marengo home. Engaging them is your choice — financial relationship disclosed per 215 ILCS 5/1575. The point is that you have the option, and the documentation to support it.
Historic Homes Need a Contractor Who Understands Preservation Review
Marengo’s Historic Preservation Commission maintains 14 landmarked buildings — the Amos Coon House, the Charles Hibbard House, the Orson Rogers House, the George Samter Building, and ten others spread through the original downtown grid. Exterior work on any of these properties may require commission review before siding can go on the wall. That process adds a step most contractors don’t know exists. We coordinate with the commission, ensure the proposed material and profile meet preservation standards, and manage the review timeline alongside the building permit through City Hall. On a landmarked Marengo home, skipping that step creates legal exposure. We handle it so you don’t have to.
Marengo Neighborhood-by-Neighborhood Siding Guide
Every section of Marengo has a different siding story based on build decade, original builder materials, storm exposure, and proximity to the Kishwaukee River. Here’s what we find on the ground.
Historic Downtown / Original Grid (1840s–1920s — The Oldest Walls in McHenry County)
This is the original settlement of Marengo — one of the oldest in McHenry County, dating back to Calvin Spencer’s arrival in 1835. Victorian, Queen Anne, Craftsman, and vernacular homes line the streets near E. Prairie Street, clustered around the 14 landmarked buildings the Preservation Commission oversees. These structures are 100 to 180+ years old. Most have been re-sided 2 to 3 times. Many have layers — original wood clapboard under aluminum under vinyl, each generation nailed over the last and trapping moisture in between. On a Historic Downtown renovation, we strip everything back to the original sheathing (or studs, on the oldest structures), assess structural condition, install modern weather-resistive barrier, and re-side with material that will last another 50 years. Small lots and mature trees mean close neighbor spacing and limited staging access — we plan for that in the timeline. Properties on the Preservation Commission list may require review of material choice and profile before work begins.
Post-War Neighborhoods (1950s–1970s — Everything Is Past Its Expiration Date)
Ranches, split-levels, and small colonials east and south of the downtown core. These homes are 50 to 70+ years old. The original materials have long since exceeded their intended lifespan. Builder-grade vinyl siding — the thin stuff, 0.040″ panels — was the standard spec on these homes when they were re-sided in the 1990s. That vinyl is now 30 years old, faded, brittle, and losing its lock tension with every temperature cycle. Underneath, the sheathing has been taking moisture for decades. The Kishwaukee River’s humidity accelerates deterioration on these homes because the original construction used minimal vapor barriers compared to modern standards. Hardie or SmartSide with a full weather-resistive barrier replacement is the standard recommendation here. At Marengo’s median home value of $229,900, this upgrade represents a significant improvement in both curb appeal and real resale value.
Indian Trails (1988–2004 — The 55+ Community Entering Its First Renovation Cycle)
Active adult 55+ community near Indian Oaks Trail. Single-family ranch and villa-style homes ranging from 994 to 1,800 square feet. These homes are 20 to 35 years old — the earliest builds are deep into the first exterior renovation cycle. The 55+ resident demographic values minimal disruption, single-story access (no scaffolding surprises), and clear communication about timeline and cost. Indian Trails homes are smaller than the post-war neighborhoods, which means lower total project cost even at fiber-cement pricing. A 1,200-square-foot Indian Trails villa with 1,400 square feet of wall area can re-side in Hardie or SmartSide for $17,000 to $23,000 including all trim, wrap, and permit. That number drops further with GreenSky financing if spreading the investment makes more sense.
Deerpass (1990s–2000s — Builder-Grade Materials Approaching End of Life)
Single-family subdivision with homes now 20 to 30 years old. Modern-era construction with better framing, better sheathing, and better original house wrap than the post-war neighborhoods — but the siding itself was still builder-grade. Deerpass homes tend to show the classic symptoms of aging vinyl: south-facing walls faded two full shades lighter than north-facing walls, lock lines loosening at the bottom courses, and minor hail impressions from the 2024 and 2025 storm seasons visible if you look closely. These homes are solid underneath. The sheathing is generally in good shape because the construction era included vapor barriers and flashed windows. That makes Deerpass one of the cleaner conversion projects in Marengo — strip the vinyl, verify the sheathing, re-wrap, and install Hardie or SmartSide with minimal repair work behind the panels.
South/East Expansion (2000s–2010s — Storm Damage Is the Primary Concern)
Newer subdivisions along Marengo’s southern and eastern edges. These homes are 10 to 20 years old, built to modern code with proper flashing details and weather-resistive barriers. Age-related deterioration is not the issue here. Storm damage is. The open farmland surrounding Marengo means these homes on the town’s periphery catch the full force of every system rolling in from the west with zero windbreak. If your South/East expansion home took hail in August 2025 or wind damage in April 2026, the siding may look intact from the street but have hairline fractures that are letting water behind the panels right now. We evaluate every newer home based on storm exposure and lot orientation, not just build year. Some need fiber cement now. Others are fine with a panel-by-panel repair. The inspection tells the story.
Kishwaukee River Corridor (Various Eras — Moisture Is the Constant)
Properties along the Kishwaukee River on the western edge of town and through the river corridor that defines Marengo’s geography. These homes span every era from the 1870s to the 2000s, but they share one characteristic that overrides everything else: elevated moisture exposure from the river itself. The Kishwaukee pushes humidity into the surrounding air from April through November. River-corridor homes see accelerated siding deterioration, ice dam damage at the roofline, and gutter failures that compound the moisture problem at the wall plane. I’ve pulled vinyl off river lots in Marengo and found sheathing soft enough to push a screwdriver through without resistance. Fiber cement is the only material I recommend within a quarter mile of the Kishwaukee. No exceptions, no debate, no sales pitch for something cheaper.

Marengo Siding FAQs
How much does siding replacement cost in Marengo?
Hardie fiber cement and LP SmartSide both install at $12 to $16 per square foot — identical pricing for two different looks. Premium vinyl runs $8 to $10. Cedar for Historic Downtown restorations requiring architectural fidelity lands at $16 to $22. On a Marengo home with 1,800 square feet of wall area, a fiber cement or SmartSide re-side totals $22,000 to $30,000 including new house wrap, all trim, and the city building permit. Sheathing repair on Kishwaukee River corridor homes adds cost that cannot be estimated until the old siding comes off. That line item appears in your proposal as a per-sheet allowance so nothing surprises you. GreenSky financing is available to spread the investment.
What siding material performs best near the Kishwaukee River?
Fiber cement. Hardie does not absorb water, does not swell, does not grow mold, and does not delaminate when river-corridor humidity sits elevated for eight months straight. SmartSide engineered wood runs a close second — the SmartGuard zinc borate treatment penetrates every strand, resisting moisture, fungal decay, and termites in a way that surface-treated wood cannot match. Vinyl on a lot within a quarter mile of the Kishwaukee is the wrong call. The lock seams fail under sustained humidity, water channels behind the panels, and the sheathing rots where you cannot see it. I’ll tell you that before I write a proposal, even when it means steering you toward a more expensive product.
Do I need a permit for siding replacement in Marengo?
Yes. The Marengo Building Department at 132 E. Prairie Street (extension 211) requires a permit for siding replacement under standard McHenry County building codes. We submit the application, schedule inspections around installation progress, and close the permit when the building department gives final approval. If your property is one of the 14 landmarked buildings or sits within a historic overlay district, the Marengo Historic Preservation Commission may require exterior review as well — we coordinate that process. Reach the building department directly at (815) 568-7112 if you want to verify anything independently.
Is storm damage from August 2025 still claimable on my insurance?
For most policies, yes — but the filing window narrows every month. Carriers use elapsed time to reclassify storm damage as pre-existing wear and tear. The documented record from August 2025 is strong for Marengo: NWS-confirmed 60 to 70 mph winds over three consecutive days, hail damage across western McHenry County, power outages throughout the area. That evidence pins damage to a specific date range. If your siding shows cracks, dents, or holes from that event and you haven’t filed, take photos now and call your carrier. IHC Public Adjusters — separately licensed in Illinois — evaluates damage and advises on claim viability at zero upfront cost (215 ILCS 5/1575).
Does the Marengo Historic Preservation Commission affect my siding project?
Only if your home is one of the 14 landmarked buildings or sits within a designated historic overlay area. The commission maintains properties including the Amos Coon House, Charles Hibbard House, Orson Rogers House, and others throughout the original downtown grid. Exterior modifications on these structures — including siding replacement — may require review and approval before work begins. The review focuses on material selection and architectural profile, not color. We handle the review process and coordinate it with the building permit timeline so both approvals align and the project doesn’t stall between agencies.
How long does a siding installation take in Marengo?
Plan for 7 to 14 working days on a full re-side. Fiber cement and engineered wood require precision cutting and slower fastening schedules than vinyl. A vinyl-to-Hardie conversion on a Deerpass ranch or Indian Trails villa averages 7 to 10 days. Historic Downtown homes with multiple layers to strip and sheathing damage to address can push toward the 14-day mark or slightly beyond. Weather delays happen — Marengo sits in the Rockford storm corridor and catches the leading edge of systems moving east. Any delay is communicated in advance. The exact timeline is part of your written estimate before the first panel comes off.
