Quieter, warmer, brighter.

★★★★★Fourteen windows in one day, and the crew vacuumed better than we do. The traffic noise from Hawthorne is just… gone.

FAQ

Clear answers.

How long does installation take?

Most homes take one day: about 30–45 minutes per window. Patio doors take 2–3 hours each.

Do you replace the whole frame?

We recommend full-frame replacement wherever we find rot or air leaks. Otherwise an insert install keeps your original trim. Your consultant will show you which applies.

What rebates can I get?

Energy Trust of Oregon pays up to $1.25 per sq ft for qualifying windows, and federal tax credits can add up to $600. We file the paperwork for you.

Is the warranty really lifetime?

Yes: glass, frames, hardware and our labour for as long as you own the home, transferable once to the next owner.
