Friday Harbor climbs a hillside straight out of the water, so the town's weather-facing walls take rain pushed sideways off the harbor for months at a time, while the shaded streets up the hill trade wind for moss — tree cover and north-facing walls that never fully dry between storms.
Inside town limits the stock runs by era up the hill: 1890s–1900s homes and false-front commercial buildings around Spring Street — the core of the town's designated historic district — cannery-era cottages from the waterfront's packing-company years, mid-century homes above them, and newer construction toward the airport. Each era fails differently, and each gets a different plan.
What we see most in Friday Harbor: century-old wood siding moving under generations of paint on the town's oldest blocks, bottom courses gone soft on harbor-facing walls, LP-era boards from the '80s and '90s swelling at the seams on the newer edges, and salt-corroded fasteners on every exposure — the town is surrounded by water, and hardware fails here years before boards do.
…and everywhere else inside city limits, plus surrounding San Juan County.
Friday Harbor'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 Friday Harbor homes, fiber cement — it shrugs off all-sides salt and a century of island repaints without cedar's maintenance cycle. On the town's historic-district and cannery-era stock, lap and shingle profiles reproduce the period look in a material that satisfies both the weather and a review board that cares about detailing.
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 Friday Harbor. 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 Friday Harbor 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.
