The Experts You Can Trust

Our Siding Manufacturer Partners

We pull the old siding back far enough to inspect the sheathing and house wrap on every job, because in this climate the barrier behind the siding matters more than the siding itself.

Siding Replacement Services Across Dane County & Southern WI

Full re-sides, partial replacement, and the repair work that's usually hiding behind the old siding.

  1. Fiber Cement Siding

    James Hardie lap, shingle, and panel. The most dimensionally stable option for Wisconsin freeze-thaw, installed to Hardie's fastening and clearance specs so the warranty holds.

  2. Engineered Wood Siding

    LP SmartSide & Diamond Kote lap and panel. Real wood texture, lighter than fiber cement, easier to work on complex elevations, at a lower price point. Learn more about LP SmartSide siding.

  3. Vinyl & Insulated Vinyl

    CertainTeed, Mastic and Ascend insulated panels. The budget option, and perfectly sound when the wall behind it is detailed correctly, which is where most vinyl jobs go wrong. As vinyl siding installers across Dane County, we detail that wall on every job. The foam backing also helps your heating bill. See how new siding improves energy efficiency.

  4. Sheathing & Rot Repair

    What we find behind old siding more often than not. We replace soft OSB and rotted framing before new siding goes up, priced transparently.

  5. House Wrap & Flashing

    The layer that actually keeps water out. Proper weather barrier, window and door flashing, and correct lap direction — the part a cheap bid skips.

  6. Storm & Hail Siding Repair

    Cracked, holed, or wind-torn siding, documented for your insurer. We handle siding insurance claims from inspection through the adjuster meeting.

    Siding Failures Are Moisture

    In our experience, most siding we're called to inspect in Dane County failed because water got behind it — not because the material wore out. Backwards house wrap laps, missing window flashing, and no clearance at grade are the usual culprits. That's why we quote the wall assembly, not just the siding, and why the cheapest bid is often the one skipping the layer that matters. Here's more on choosing siding that holds up to Wisconsin storms.

Financing example: a $15,000 project is about $161/month over 15 years at 9.99% APR, or $625/month at 0% APR over 24 months. These are illustrations, not offers; rates and approval through our lending partner Upgrade depend on credit. See financing options

How Our Siding Replacement Process Works

Most siding projects take one to two weeks, weather depending.

  1. 1. On-site estimate

    We assess the elevations, check for existing moisture damage, and talk through material.

  2. 2. Written scope

    Line-item quote naming siding, wrap, flashing, and trim — with a sheathing repair allowance.

  3. 3. Tear-off & inspect

    Old siding off, sheathing checked wall by wall. Rot gets replaced before we go further.

  4. 4. Barrier & install

    House wrap, flashing, then siding to manufacturer spec, one elevation at a time.

  5. 5. Trim & walkthrough

    Corners, trim, caulk, and cleanup. Every siding job is backed by our 25-year workmanship warranty.

How much does siding replacement cost in Madison, WI?

Keep the current answer, then add at the end: Ask about 0% siding financing to spread the cost over a term that fits your budget.

What is the best siding for Wisconsin weather?

Fiber cement and engineered wood both hold up well to freeze-thaw cycling. Fiber cement is the most dimensionally stable and fire resistant, but heavier and pricier. Engineered wood is lighter, easier on complex elevations, and gives a real wood texture at lower cost. Vinyl is the budget option and performs fine installed correctly. But the honest answer is that material matters less than the water barrier behind it — most siding failures here are moisture problems, not material failures.

Does James Hardie siding hold up in Wisconsin?

Yes. James Hardie makes a climate-specific line engineered for freeze-thaw regions, formulated to resist moisture absorption and cracking through repeated freezing. The catch is that it must be installed to Hardie's fastening, clearance, and gapping specifications or the warranty is void — which is exactly why installation quality matters more than the name on the label. We install to Hardie spec and register the warranty for you.

Why is my siding cupping or buckling?

Almost always one of two things: water in the sheathing behind the siding, or fasteners driven too tight so the material couldn't expand and contract with temperature. Both are installation issues, not material defects. Replacing the siding without addressing the wall behind it just resets the clock on the same failure, which is why we pull it back and inspect before quoting a fix.

Can you side over my existing siding?

We strongly advise against it, and usually won't. Siding over the old layer means you can't inspect the sheathing, can't correct the weather barrier or flashing, and can't fix whatever moisture problem is likely already underway. It hides exactly the things that cause walls to fail. Full tear-off costs more up front and is the only way to know what you're actually dealing with. Here's what Madison homes face each year behind the siding.

How long does a siding job take in Madison?

Most homes take one to two weeks, depending on size, number of stories, and how much sheathing repair turns up once the old siding is off. Historic homes and complex elevations with lots of gables and trim run longer. We give you a real timeline at the estimate rather than a vague window, and we work one elevation at a time so the house is never fully exposed. Gentle cleaning helps too. Here's how to clean vinyl siding without damaging it.

Do I need historic approval for siding in Madison?

If your home is in a designated district — Mansion Hill, Third Lake Ridge, University Heights, Marquette Bungalows and others — street-visible material and profile changes go through Landmarks Commission review. Vinyl is often rejected in these districts; fiber cement and engineered wood in matching profiles usually pass. We've been through the process and can bring options likely to be approved.

How long does vinyl siding last in Wisconsin?

Most vinyl siding lasts 20 to 30 years here. Deep cold makes vinyl more brittle, so impacts in January can crack panels that would flex in July, and installation matters as much as the product: panels nailed too tight can't expand and contract, and they buckle or crack early. Insulated vinyl panels are more rigid and hold up better than standard thin-gauge vinyl.

What's the best vinyl siding for Wisconsin homes?

For most homes, an insulated vinyl panel from a major manufacturer like CertainTeed, Mastic or Ascend. The foam backing makes panels more rigid, flatter on the wall and more impact-resistant than standard vinyl. The brand matters less than the wall behind it: correct house wrap laps, window flashing and clearance at grade decide whether any vinyl lasts.
