Bellingham Window Replacement provides professional egress windows for daylight basements in Bellingham, WA for residential and commercial properties across Whatcom County and northern Skagit. Bellingham is built on hills, so daylight basements are everywhere: Sehome, Columbia, the South Hill and most of the newer subdivisions out toward Barkley. Turning that lower floor into a legal bedroom means an egress opening, and there is no talking your way around the numbers.
The numbers are fixed and there is no arguing your way around any of them. A sill any higher than 44 inches off the finished floor kills the opening on its own, and so does anything under 20 inches wide or under 24 inches tall. The open sash then has to leave 5.7 square feet behind it, or 5.0 on a grade floor.
Net clear means the hole a person can genuinely climb through once the sash is wide open. It is not the rough opening in the wall, and it is certainly not the frame dimension printed on the order form. A casement will usually reach the number in a narrower opening than a slider or a hung unit can.
Now the part that belongs on this particular website rather than on anybody else's. In nearly every finished basement we look at, the egress window turns out to be the only openable window on that entire floor. It is not just the escape route. It is the whole ventilation system for a room that people sleep in.
Basements are the coldest and dampest part of any house in this county by a wide margin. The slab and the walls sit in contact with ground that stays wet for eight months of the year. Finish that space, put a bed in it, close the door at night and the moisture has exactly one path out.
So we cut the well larger than the code minimum whenever the grade allows it. A generous well means you can leave the window open in the rain without the room flooding, and it means the bedroom gets real air rather than the four inches of clearance the rule technically requires. It costs very little extra at dig time, and it is the one place on this job where going bigger than the rule is obviously worth doing.
Drainage is not optional and it is where most retrofits in this county fail. The well needs a gravel base connected either to footing drainage or to daylight, because a well that fills up is simply a bathtub bolted to your foundation wall. We dig it, we prove that it drains, and only then do we set the window.
Cutting a new opening into a concrete or block wall is real work: saw cutting, a lintel over the head, and a proper waterproofing detail where the new frame meets old concrete. We permit these jobs through the City or through Whatcom County. That is not a corner anybody should be cutting on a bedroom. Permits also mean somebody besides us has looked hard at the lintel.
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.
