Is your home doing its job when the weather turns?

Most people call us in February, not July. That is when you find out what your windows actually are: the draft you feel from the couch, the bedroom that never quite warms up, the fog trapped between panes that no amount of wiping fixes.

None of that is your furnace failing. It is thirty-year-old glass and worn seals doing exactly what old glass and worn seals do. Replace them and the house gets quieter, holds its heat, and stops sweating on the inside of the glass. I have watched it happen 2,300 times. It is not a sales line, it is physics.

If any of the list here sounds like your house, get a quote now and beat the winter rush. The number we give you holds for 12 months either way.

  • Drafts you can feelCold air moving near the glass on a still night means the seals are gone.
  • Fog between the panesMoisture inside the unit means the insulating gas left a long time ago.
  • Rooms that will not hold heatSingle-pane and worn double-pane glass radiate cold straight into the room.
  • Street noise indoorsIf you hear tires on wet pavement from bed, the glass is doing nothing for you.

Installed by our own crews, not subcontractors

Every installer who walks into your home is a West Coast Windows employee. No day labor, no vague pricing, and no warranty that quietly expires. Here is what that means for your project.

Our Own Crews

Every installer is a West Coast Windows employee, factory-trained and background-checked. No subcontractors ever show up at your door.

Real Energy Savings

Low-E glass and argon-filled frames cut heat loss year-round. Every window we install carries an ENERGY STAR rating for our climate.

Your Price, Locked In

The quote we hand you is honest for 12 months. No surprise increases between your consultation and your install date.

Daily Cleanup, No Loose Ends

Floor protection down every morning, jobsite swept every night, and a final walkthrough before we call it done.

Lifetime warranty. In writing. Transferable.

Every window we install is covered for as long as you own your home, and the coverage transfers to the next owner. Our installation work is backed for 10 years on top of it.

From first visit to final walkthrough

Four steps, one point of contact, and no guesswork about what happens next.

  1. Free In-Home Consultation

    We measure your home, walk through styles and materials, and leave you with a written price, no pressure to decide on the spot.

  2. Precise Measure & Custom Order

    Once you approve the quote, we take exact measurements and order your windows or doors built to fit your home.

  3. Professional Install

    Our own crews handle the install. Most homes are done in one to two days, with daily cleanup and no loose ends.

  4. Lifetime Support

    Your warranty starts the day we finish, and our Seattle office picks up the phone if you ever need us again.

“We replaced 11 windows in our Ballard house and the difference in the bedrooms alone is worth it. The street noise dropped a lot more than I expected, and the crew finished in a day and a half.”
Rachel T. · Ballard, Seattle · Windows
“Put in a multi-slide door across the back of our house facing the water and it completely changed the room. Worth every dollar for the view alone.”
Steve R. · Kirkland · Multi-Slide Door
“A seal failed four years after install. No arguing, no fee, a tech was out within two weeks and swapped the glass under warranty.”
