A basement bedroom is only legal if it can get out.
If you want a basement room to count as a legal bedroom in Bellingham, it needs an egress window: an opening big enough to climb out of in an emergency, at the right sill height, with a window well if the opening is below grade. We size the window and the well to meet the code, cut the foundation opening, install the unit, and pull the permit so it passes inspection.
Beyond the legal part, an egress window makes a dark basement brighter and safer, and it adds real value if you ever finish or rent the space. We waterproof and detail the well so the new opening sheds water instead of funneling it against the foundation, which is the part a lot of egress jobs get wrong.

Frequently asked questions.
What does an egress window cost in Bellingham?
Egress window projects run about $2,500 to $6,500 installed in Bellingham, including the foundation cut, the window, and the well. Cutting concrete or block and detailing the well drainage are the biggest cost drivers. We quote it for free after we look at the wall.
What makes a basement window count as egress?
Code sets a minimum clear opening, a minimum width and height, and a maximum sill height off the floor, plus a window well with a way to climb out if the opening is below grade. The exact numbers are set by the building code Bellingham and Whatcom County enforce, and we size the opening to meet them.
Do you handle the permit and the concrete cutting?
Yes. We pull the permit, cut the foundation opening, set the window, install and waterproof the well, and meet the inspection. You don't have to coordinate separate trades.
