Shoreline Window Pros provides professional basement and bedroom egress windows in Shoreline, WA for residential and commercial properties across north King County. Shoreline is a daylight-basement town. The lots slope, the postwar builders took advantage of it, and the result is thousands of lower levels that are half above grade and half below. Turning one into a legal bedroom is the most common reason anyone calls us about an egress opening.
Most articles on this subject are arithmetic: minimum clear opening area, minimum width, minimum height, maximum sill height above the floor. Those numbers are published, your building official applies them, and we will confirm the current figures for your project rather than reciting them from memory here. What almost nobody explains is the part that determines the price and the risk, which is the wall.
Start with the paperwork, because it is cheap and often decisive. Shoreline did not incorporate until 1995, so the original permit record for a house built in 1953 sits in King County's files, not the city's. If the lower level was finished by an owner in 1978 and never inspected, adding an escape window does not make that space a legal bedroom. We say so before anyone spends money.
Then the opening. Enlarging a window in a wood-framed wall means a new header, fresh kings and jacks on either side, and a rough sill rebuilt from scratch. Cutting one into a poured concrete or block foundation wall means a saw crew, a lintel, and a hole in the part of the house that was doing the waterproofing. Neither is a window job at a window job's price, and a quote that treats them as one is guessing.
Here is where our local rule bites. A new opening in a face-sealed wall creates a fresh perimeter that must shed water with no drainage cavity behind the cladding to back it up. Every opening we cut gets a sloped pan, a back dam, formed end dams and head flashing lapped over the barrier. Below grade the well matters as much: a gravel bed, a drain tied to daylight, and a cover that sheds.
Which leads to the advice we give most often. If you have siding, a foundation drain, or an exterior waterproofing job coming, do the egress opening at the same time. The wall is already open, the barrier is already being replaced, and the marginal cost of the opening falls by a wide margin. Doing it as a standalone in February is the expensive version.
We also install the boring parts properly: the well itself sized to the code's projection and clear-area rules, a permanent ladder or steps where the depth requires one, and a cover that a person inside can push open without a tool.
Bring us the floor plan and a photograph of the outside wall, with a tape held against the existing opening if you can manage it. We will tell you within a day whether you have a window project or a concrete project, and those two numbers are nowhere near each other.
Our licensed and insured team brings the right materials and equipment to every job — sill pan, back dam, head flashing, flush fin, nail fin, turned end dam — and backs the work with a written workmanship warranty. We serve Shoreline and nearby communities including Seattle, Edmonds, Lynnwood, Mountlake Terrace.

Materials, equipment and how we do basement and bedroom egress windows
The difference between basement and bedroom egress windows that lasts and basement and bedroom egress windows that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with sill pan, back dam, head flashing, flush fin, 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 Shoreline 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 north King County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Shoreline Chooses Shoreline Window Pros
- ✓We open one representative wall before quoting. Finding rusted drip caps or bare sheathing costs an hour up front and prevents the change order that otherwise lands halfway through the job.
- ✓Every opening gets a pan that slopes outward, dams at its interior edge and turns up at both jambs, in flexible flashing or formed metal. In a wall with no drainage cavity, that pan is the last line of defense and we do not skip it to hit a number.
- ✓Our quotes name the NFRC certified numbers, not marketing terms. Heat loss, solar gain, light transmission and air leakage are all printed on the sticker, and those four figures are what one bid should be compared against another on.
- ✓We stock and fit both flush-fin and full nail-fin units. That choice is made by what the wall can survive, not by which one our supplier is running a promotion on this month.
