Mount Vernon sits where the Skagit River opens onto the delta, and the weather arrives sideways — southwesterly storms cross the open tulip flats with nothing to slow them and drive rain into south- and west-facing walls for months at a time, while homes up the hill through Hillcrest, Little Mountain, and Eaglemont trade that wind for evergreen shade and the moss that comes with it.
The housing stock tracks the terrain: homes near the riverfront downtown that date back toward the 1877 townsite era, framed in old-growth lumber worth preserving; mid-century stock on the hill; and Eaglemont ('90s) and Skagit Highlands (2000s) subdivisions aging out of builder-grade siding. Each era fails differently, and each gets a different plan.
What we see most in Mount Vernon: bottom-course rot on delta-facing walls that take wind-driven rain off the flats, moss-fed failures on shaded Hillcrest and Little Mountain lots that never fully dry, and cracked butt joints on Eaglemont- and Highlands-era builder-grade boards aging out on schedule. None of it is cosmetic — by the time siding shows these signs, water is usually getting behind it.
…and everywhere else inside city limits, plus surrounding Skagit County.
Mount Vernon'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 Mount Vernon 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 Mount Vernon. 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 Mount Vernon 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.

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.
