We specialize in basement egress window installation in Seattle, making your space both legal and livable.
Here’s what we bring to the table:
- Egress window cuts & installs in concrete and framed basements
- Window wells sized for escape and daylight
- Ladders or steps for wells deeper than 44″
- Well drainage tied into foundation perimeter systems
- Permit-ready designs meeting Seattle's R310 code to avoid costly re-submits
We’ll handle everything:
- Code review and recommendations for opening size
- Saw-cut into foundation or wall, install rough opening
- Fit properly sized egress window, seal, and insulate
- Build window well (≥ 9 sq ft area, ≥ 36″ depth/width) with step or ladder if needed
- Tie in drainage and finish with low-maintenance materials
- File permits and schedule inspection with SDCI
Why it matters in Seattle:
Every finished basement bedroom must have an escape route — each window must offer at least 5.7 sq ft net clear opening, be ≥ 24″ high and ≥ 20″ wide, with a sill no more than 44″ above the floor. If the window drops below grade, the well must be ≥ 9 sq ft, 36″ wide/deep, and include steps/ladders if deeper than 44″.

How we work
Initial Walkthrough & Quote
We measure existing windows, check slab depth, and discuss finish options so you know exactly what’s possible.
Design & Plan
Confirm opening size, window well dimensions, builder-grade or upgraded window type, drainage needs, and a permitting strategy that works for your schedule.
Permit Filing
We prepare and submit drawings/specs to SDCI, address redlines, and get your inspection on the calendar.
Construction
- Saw-cut foundation or wall and install the rough opening
- Flash, insulate, and set the egress window
- Build window well to code, adding ladder/steps if depth exceeds 44″
- Connect well drainage and complete final waterproofing
Finish & Inspection
We clean, trim, and accompany you during final inspection to ensure compliance and permit sign-off.
We keep the tone direct, the steps clear, and your homeowner experience stress-free.
Basement egress windows brands
We choose materials that perform in Seattle’s climate and stand the test of time:
Windows – Andersen or Milgard egress models with fixed bottom and crank-top operation, sealed for easy cleaning and smooth function.
Window Wells – Pre-cast steel or polymer systems from Boman Kemp (Easy-Well™) for quick installation and long-term durability.
Drainage – Tie directly into an existing foundation drain or install a local French drain connection for proper water management.
Seals & Flashing – High-quality waterproof membranes, below-grade-rated sealants, and sill pans to keep water out for the life of the window.
Ladders/Steps – Integrated aluminum rungs, at least 12″ wide, spaced no more than 18″ apart to meet egress code.
We sound like builders, not marketers—this is how we’d talk on site.
