What Bellingham's Weather and Housing Stock Do to Siding
Bellingham sits on Bellingham Bay with weather that arrives sideways — southwesterly storms push rain off the water and into south- and west-facing walls for months at a time, while homes up the hill toward Sehome and the Lake Whatcom side deal with heavy tree cover, shade, and the moss that comes with it.
The housing stock spans a century: craftsmans and Foursquares in Columbia and York — a neighborhood built out between 1895 and 1930 by mill-era families — post-war ranches in Birchwood, Roosevelt, and Alabama Hill, and 1990s-and-newer subdivisions toward Barkley and Cordata. Each era fails differently, and each gets a different plan.
What we see most in Bellingham: cedar and shingle siding rotted at the bottom courses on weather-facing walls — often first-growth boards from the city's own mill era that lasted a century before the paint finally failed — LP-era siding from the '80s and '90s swelling at the seams, 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 everywhere else inside city limits, plus surrounding Whatcom County.
What New Siding Returns on a Bellingham Home
Bellingham'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. On a full-home re-side, sheathing rot repair is typically included at no extra cost, and anything past the sheathing, which is very uncommon, is quoted as a change order.
What We Recommend for Bellingham Walls
For most Bellingham homes, fiber cement — it shrugs off the bay's sideways rain and the moss pressure of shaded 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, ask us about financing options.

Our Recommendation for Bellingham: James Hardie Fiber Cement
We recommend fiber cement — James Hardie specifically — and it’s the only siding we recommend for Bellingham homes. 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 limited warranty on the boards, and ColorPlus factory finishes carry their own 15-year limited finish warranty.
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. For Bellingham homes, Hardie is the answer we’d put on our own house.
What Exterior Work Costs in Bellingham
Most single-family whole-home siding replacements typically land between $20,000 and $60,000, driven mainly by home size and stories. As a standalone project, window replacement typically runs $1,100–$2,500 per standard vinyl window installed depending on brand, type, and size. Windows replaced during a re-side typically run $900–$1,600 per window (20–35% less), since demolition, disposal, and administrative overhead are already carried by the siding project.
Prices change often with inflation, material costs, the economy, and tariffs and other policy changes, so these ranges are a guide, not a quote. Your written estimate has the current price for your home.
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.
What Stands Behind the Work
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.
How Long It Takes
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.
