Skagit County runs from salt water to the Cascades, and siding takes different punishment along the way: marine exposure and salt air in Anacortes, La Conner, and Samish Island; open delta wind driving rain across Mount Vernon, Burlington, and Conway farm flats; and shade-fed moss up the valley toward Sedro-Woolley and Concrete. The December 2025 flooding on the Skagit River added its own chapter — lowland walls that took water need drying and honest rebuilds, not paint.
The housing stock tracks the terrain: 1890s originals on La Conner's historic waterfront, riverfront downtown blocks and mill-town stock in Mount Vernon and Sedro-Woolley, marine bungalows in Anacortes, farmhouses across the delta flats, and Skagit Highlands-era subdivisions aging out of builder-grade siding. Each era fails differently, and each gets a different plan.
What we see most across Skagit County: cedar and shingle siding rotted at the bottom courses on weather-facing walls, LP-era siding from the '80s and '90s swelling at the seams, fasteners corroding years early on salt-exposed walls near the water, and moss working into joints on shaded north walls. None of it is cosmetic — by the time siding shows these signs, water is usually getting behind it.
…and every community in between, county-wide.
Skagit County's housing market rewards exterior condition — buyers compare street by street, and appraisers see siding before they see anything else. National cost-vs-value data consistently ranks fiber cement siding replacement among the highest-returning exterior projects at resale, and in a wet-climate market, "recently re-sided" answers the first question every inspector asks.
What your project costs depends on material, home size, and stories — and on what we find under the old siding. That's why every bid is measured on site and itemized: the number you approve is the number you pay, with rot repair priced transparently if we find it.
For most Skagit County homes, fiber cement — it shrugs off delta wind, river-flood memory, and moss on shaded hillside lots without cedar's repaint cycle. On craftsman-era homes, lap and shingle profiles keep the period look in a material that doesn't rot at the bottom course.
One thing we don't install: vinyl siding. In this climate it traps moisture against the wall and fails in ways we're not willing to warranty. If budget is the driver, we'd rather show you an engineered-wood option that actually holds up here.

See All Projects →We install several siding materials, and we recommend fiber cement — James Hardie specifically — for nearly every home we work on in Skagit County. In a wind-driven-rain state, fiber cement doesn’t rot, doesn’t feed moss, doesn’t warp, and shrugs off the freeze-thaw cycles that crack lesser boards. It carries a 30-year substrate warranty, and ColorPlus factory finishes hold their color for 15 warranted years without repainting.
As a James Hardie Elite Contractor we install to the spec that keeps that warranty valid — fastening, clearances, and flashing details checked on every wall. If a different material genuinely fits your project better, we’ll say so plainly in the bid — but for most Skagit County homes, Hardie is the answer we’d put on our own house.
Most single-family whole-home siding replacements typically land between $20,000 and $60,000, driven mainly by home size and stories. Window replacement typically runs $900–$2,500 per window installed depending on brand, type, and size — and typically 25%+ less per window when replaced during a re-side, since demolition, disposal, and administrative overhead are already carried by the siding project.
Nationally, fiber cement siding replacement is one of the best-returning exterior projects at resale — recent Cost vs. Value Report data puts its cost recoup above 100% (a national figure; local results vary). Every bid is measured at your home and itemized line by line — the ranges are for orientation, not quotes. Financing options are available.
James Hardie siding carries a 30-year substrate warranty, with ColorPlus finishes warranted for 15 years. Windows carry the full manufacturer warranty.
On top of the product coverage, our own workmanship warranty is included on every project; the terms are spelled out in your bid.
A full home siding replacement typically runs one to four weeks on site depending on size, sheathing condition, rot, and whether we're painting. A whole-home window replacement typically runs three to seven days — full-frame nail-flange replacement, not pocket inserts, which takes longer and is worth it.
Your schedule is in the bid before work starts, and the final inspection is part of it.
