Sliding glass and French patio doors that glide right and seal tight, tempered for safety and Low-E for the energy savings. We fix the rot and out-of-square openings the old door hid.
When the old slider sticks, the opening is usually the problem.
A patio door is a big piece of glass that moves, so it has to be set right or it drags, leaks, and fogs up. We replace sliding glass and French patio doors with units that glide on good rollers and seal tight at the weatherstrip. The glass is tempered for safety and Low-E to cut heat loss, which matters on a wall that's mostly window.
Old aluminum sliders almost always hid something: a scuffed track, a rotted sill, or an opening that's gone out of square. We fix what we find so the new door sits plumb and runs smooth, instead of fighting the same problem the old one did. You get a line-item quote and a clean, square install.

Frequently asked questions.
How much does a patio door cost installed in Bellingham?
Installed patio and sliding glass doors run about $1,800 to $5,500 in Bellingham. A standard two-panel vinyl slider is at the low end; a wide multi-panel or French patio door in fiberglass or clad wood is at the high end. We quote it for free.
Why does my old sliding door stick?
Usually the rollers are worn, the track is packed with grit, or the opening has settled out of square. Sometimes the sill underneath has rotted. When we replace the door we fix the opening so the new one glides instead of fighting the same problem.
Is the glass tempered and energy efficient?
Yes. Patio door glass has to be tempered for safety because it's a big pane at floor level, and we spec Low-E coatings and argon fill so a wall of glass doesn't bleed heat in our cold, wet winters.
