Bellingham Window Replacement provides professional custom window installation in Bellingham, WA for residential and commercial properties across Whatcom County and northern Skagit. In this city custom usually means custom-sized before it means custom-shaped. The hills put daylight basements under half of Bellingham, and a basement bedroom here answers to a rule written more strictly than in any neighboring state.
Washington deleted the relief that homeowners elsewhere lean on. Its amendment lists the model code's replacement-window paragraph, R310.5, as not adopted, so a bedroom unit earns no credit for arriving as the biggest stock size the hole will take. The full requirement stands.
That requirement is four numbers at once: a net clear area of 5.7 square feet, 5.0 where the opening sits at the grade floor, with clear height reaching 24 inches, clear width reaching 20, and the sill sitting no more than 44 inches up from the finished floor.
Which quietly turns custom ordering into a tool rather than a luxury. When the largest catalog casement in your existing opening measures out at 5.4 square feet, the options are cutting the opening wider or ordering a unit built to the size that clears. The second is frequently the cheaper morning's work.
Shaped work exists here too, and it is concentrated. Radius heads on the older Eldridge and South Hill houses, trapezoids under a gable rake in the newer builds out toward Barkley, and the oversized fixed lite pointed at the bay or at Mount Baker from a hillside living room.
Templating decides whether any of it fits. A head gets patterned in rigid board with the spring line marked, a rake gets measured in degrees against real framing, and the glass bite and frame depth get recorded so the new unit lands on the existing trim line rather than beside it.
Lead time is the part that changes behavior. A shaped or non-standard unit is built for one address, so your deposit is gone as soon as the order leaves for the shop and no other customer can absorb that glass. We put measured sizes on the proposal and read them back before release.
Plan for the decade as well. A single-address shape has no warehouse standing behind it, and a lite broken eight winters from now restarts the pattern, the release and the queue. Keep the pattern, the rake angle and the glass specification somewhere you will find them again.
Expect a permit. The residential code arrives in this state intact, administrative chapter and all, and its exempt-work list covers fences, decks, awnings and painting rather than windows, so plan on the City of Bellingham Permit Center, or Whatcom County outside the limits, with the energy compliance sheet attached. Widening an opening adds a header and a structural review.
The recommendation, including the case against this page. If a stock size fits your opening with extension jambs and nobody sleeps in that room, take the stock unit and spend what you saved on flashing and air sealing. Order custom where the bedroom numbers demand it, where the shape is genuine, or where the view is the reason you bought the house.
Our insured team brings the right materials and equipment to every job — trickle vents let into the head of a replacement sash, a heat-recovery ventilator ducted to the bedrooms, six-mil black polyethylene ground cover across a crawl space floor, an insulated bath fan duct run short and straight to a wall cap, a backdraft damper that actually closes when the fan shuts off, a two-week humidity log taken before anything gets ordered — and backs the work with a written workmanship warranty. We serve Bellingham and nearby communities including Ferndale, Lynden, Blaine, Birch Bay.

Materials, equipment and how we do custom window installation
The difference between custom window installation that lasts and custom window installation that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with trickle vents let into the head of a replacement sash, a heat-recovery ventilator ducted to the bedrooms, six-mil black polyethylene ground cover across a crawl space floor, an insulated bath fan duct run short and straight to a wall cap, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Bellingham job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in Whatcom County and northern Skagit means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Bellingham Chooses Bellingham Window Replacement
- ✓We take a relative humidity reading in the house before we price a single window, because the complaint that brought you to us is often not about glass at all
- ✓If your bath fans are the problem we say so and leave without an order, and we tell you roughly what the fan should cost you
- ✓We quote the sealed unit before the whole window, since a fogged pane in sound sash with sound hardware is a glass job and gets priced like one
- ✓Every replacement quote names the ventilation the house will need once it is tight, in writing, next to the window price
