Scope of Work

What a Seattle window replacement includes

Every remodel is scoped to your home, your written estimate lists exactly what's included. A sample of what we cover:

▸Full-frame and insert window replacement

▸Energy-efficient, double-pane units that cut drafts and noise

▸Interior and exterior window trim and casing, installed and finished

▸Proper flashing and sealing to keep water and air out

▸Rot and frame repair discovered during replacement

▸Profiles matched to your home's style, classic or modern

▸Single windows through whole-home replacements

▸Cleanup and haul-away of old units

Most windows are replaced in one to three days depending on count and whether trim and framing need work; we confirm lead times when the units are ordered.

Local Knowledge

Remodeling Seattle homes

Seattle's classic stock, 1900s–20s Craftsman homes in Beacon Hill, Columbia City, and West Seattle, brings beautiful bones and century-old systems. We're experienced with the realities: settling foundations, lath-and-plaster, undersized panels, and the SDCI permit process that catches many homeowners off guard.

Permits: the Seattle Department of Construction & Inspections (SDCI) issues residential permits; Seattle's process is the most involved in our service area and we build its review timelines into the schedule. We handle the entire permit process, applications, plan documents, and inspection scheduling, on every project.

Remodeled my kitchen and got it done a few days faster than expected, and it looks so nice now I can't wait to host people over.

★★★★★

Did an excellent job doing a complete renovation/remodel of our bathroom and repairing/replacing a portion of siding on house. Really listened to what I wanted for my dream bathroom and delivered A+.

Budget & Planning

What to expect on cost

Window cost is driven by the unit, the count, and whether the openings need framing or trim repair. We measure each opening, account for any rot or flashing issues, and quote the units and labor separately so you see exactly what you are paying for.

Q & A

Questions, answered straight

Will new windows really lower my energy bills?

Modern double-pane units with proper sealing make a real difference in an older Washington home: less heat loss in winter, less noise year-round. We point out which windows are costing you the most and prioritize those.

Do you fix the trim and any rot you find?

Yes. Old windows often hide rotted framing or failed flashing. We repair what we find and install proper flashing and trim so the new window is sealed and finished, not just dropped into a bad opening.

Can you replace just a few windows?

Absolutely. Plenty of clients start with the worst offenders, the drafty north side, the picture window that fogs, then replace the rest over time. We are glad to phase it.

Which Seattle neighborhoods do you serve?

All of Seattle, including West Seattle, Beacon Hill, Columbia City, Rainier Valley, Georgetown, plus the surrounding King County area. We're about 50 minutes from our shop, we schedule Seattle projects in dedicated blocks.
