What we write about, and why
Every post here answers a question Bellingham property owners actually ask before they hire anyone — what work costs, which materials are worth the upcharge, how long a job really takes, and the shortcuts that look fine for two years and then do not.
The writing comes from the same people doing the work in Bellingham, WA and Whatcom County and northern Skagit, which is why the numbers are specific and the advice sometimes tells you not to spend money.

Skip the articles and go to the page for what you need — each one covers pricing, scope and how to start:
- Energy-Efficient Windows and Air Sealing in Bellingham — Bellingham runs about 5,559 heating degree days a year, so nearly all the energy your house loses goes out as heat rather than in as sun. The number that decides your bill is whole-unit U-factor.
- Welded Vinyl Replacement Windows in Bellingham — Vinyl is the correct answer for most houses in this market, and we will say so out loud even when a pricier frame is sitting open in the same brochure. In a mild marine climate its one genuine weakness, thermal movement, barely gets a chance to show up.
- Pultruded Fiberglass Windows in Bellingham — Pultruded fiberglass costs real money, and in this climate the usual sales pitch for it does not apply. Nobody in Bellingham is buying fiberglass because their vinyl was about to warp.
- Clad-Wood Windows and Interior Wood Trim in Bellingham — Clad-wood is the right product for a fair number of houses here, particularly in the older neighborhoods where a plain vinyl frame in a period opening looks like a mistake from the sidewalk. It is also the product most reliably destroyed by a humidity problem nobody diagnosed.
- Aluminum Windows and 1970s Slider Swaps in Bellingham — A very large share of the houses between here and Sedro-Woolley went up between 1965 and 1985 with single-glazed aluminum sliders. Whatcom County's median home dates to 1988.
