If your windows have a few good years left, we will tell you that instead of selling you a job.

The part of a window job you never see

This is a real install, not a stock photo. The blue tape around the opening is flashing. It is what keeps Northwest rain out of your wall once the trim goes on, and it is the part a cheap install skips.

Our crews flash and seal every opening the same way we detail windows on commercial buildings. If we find rot around a frame when the old window comes out, we show you before it gets covered and price the repair before we do it.

We install windows on commercial buildings for a living

Through our sister company, Exteriors Design, our teams have completed large-scale commercial window installations on mid-rise and high-rise buildings across Portland and Seattle. Those jobs demand strict waterproofing, flashing precision and long-term durability.

Your house gets those crews and that same standard. Most window companies have never had to build to it.

20+ years

Family-owned and local. Not a franchise, not an investor-backed call center.

Factory-certified

Trained to install Milgard windows the way Milgard says to, so the warranty means something.

Water first

Flashing and sealing done for a climate that rains eight months a year.

How to tell your windows are done

Windows fail slowly. By the time one is obviously bad, the rest are usually not far behind.

Drafts you can feel

Stand by the window on a cold night. If you feel air moving, the seal or the frame has given up.

Fog between the panes

That is a failed seal. The insulating gas is gone and the glass will not clear on its own.

Hard to open or lock

Frames that have warped or swollen. It is a safety problem as much as an annoyance.

Rot or soft wood at the sill

Water has been getting in around the frame. Left alone it moves into the wall.

Single pane glass

One layer of glass, no insulation. Most of the heat you pay for goes straight through it.

Condensation on the inside

Cold glass pulling moisture out of the room air, which over time feeds mold on the sill.

What we put in

Milgard vinyl

V250 Style Line, V300 Trinsic and V400 Tuscany series. Low maintenance, energy efficient, the pick for most Portland homes.

Milgard fiberglass

C650 Ultra and C700 series. Stronger than vinyl, less expansion and contraction, a cleaner look on bigger openings.

Every common style

Double hung, casement, picture, bay and bow, and custom shapes. We help you pick by room, not by catalog.
