Bellingham Window Replacement provides professional glass repair and failed insulated units in Bellingham, WA for residential and commercial properties across Whatcom County and northern Skagit. This is the page where we talk ourselves out of work, so let us get straight to it. If water is running down the inside of your windows and you can wipe it off with a towel, your seals have not failed and we will not sell you new glass.
The test takes five seconds and you can do it right now. Wipe the glass with your sleeve. If the wetness comes away on the cloth, it is room-side condensation and it is your indoor air talking to a cold surface. If the haze or the droplets sit between the two panes where no cloth on earth can reach them, that is a failed sealed unit.
Failed units we fix, and gladly, because it is good work. The sash stays, the frame stays, we take the old unit out of the glazing pocket and set a new one with a warm-edge spacer and argon. It is a fraction of the price of a window and it is the right answer whenever the sash and hardware are sound.
Room-side condensation, on the other hand, is arithmetic rather than a defect. Air at 68 degrees and 50 percent relative humidity has a dew point close to 49 degrees. Any surface in that room colder than 49 degrees will collect water on it, and on a January night in Bellingham the coldest surface in any room is always a window.
Building Science Corporation's guidance for cold-climate heating seasons is 30 percent relative humidity or lower at 70 degrees. Most of the houses we take readings in are running between 45 and 60 percent in December. That gap is where all the water comes from, and it is genuinely not the window's fault in any sense. That is a real difference, and closing it is the whole job.
The house is producing it: showers, cooking, laundry drying on a rack, houseplants, a gas range under a hood that recirculates, and in this county very often an uncovered crawl space floor evaporating ground water up into the floor system all winter long. Washington's code wants six-mil black polyethylene over that dirt for exactly this reason.
So what we actually do on these calls is turn up with a hygrometer, look at the bath fans, hold a hand over the kitchen hood outlet to find out whether it goes outside or straight back into the room, and then open the crawl space hatch and shine a light around. None of that takes long. Then we tell you what fixing it costs.
Sometimes the answer is a 150 dollar fan and a change of habit. Sometimes it is a liner and a continuously running exhaust sized to the bedroom count. Occasionally it really is the windows, and we will say so just as plainly. But the order of operations is measure first, and we are not moving off it for anybody.
Our licensed and 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 glass repair and failed insulated units
The difference between glass repair and failed insulated units that lasts and glass repair and failed insulated units 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
