Valley windows sort by street age. The post-war ranches and ramblers on the older grid still run aluminum sliders — the ones with frost on the inside track every January, because aluminum carries the outdoor cold straight through the frame and gives your indoor humidity somewhere to freeze. The Greenacres and Ponderosa-area subdivisions from the 90s and 2000s got builder-grade vinyl instead, and those units are now fogging up one by one as their glass seals let go.

Domex Construction replaces both kinds across Spokane Valley. We're an exterior contractor first, so the flashing and sealing where the window meets the wall — the part that decides whether the install lasts — is the part we build the job around. Washington license DAVYDCI833NC, fully insured, free estimates.

Why Valley Glass Wears Out Early

Sun does most of it. The newer subdivisions sit on open lots with little mature shade, so a south- or west-facing window takes direct sun from mid-morning to sunset all summer. Every hot-cold cycle flexes the insulated glass unit — the gap between panes expands and contracts, pumping at the perimeter seal — and a seal that might last thirty years on a shaded lot fails in fifteen or twenty on a bare one. Once it fails, the argon is gone, moisture fogs the gap, and the window quietly stops insulating no matter what its original sticker said.

Wind finishes the job on the older stock. Aluminum sliders seal against a felt or pile weatherstrip that flattens with age, and on a gusty corridor day you can hold a hand near the track and feel the outdoors coming through. Between the conductive frames and the leaky tracks, those ranches are heating the backyard all winter.

What goes in depends on the opening. On aluminum sliders we usually recommend full-frame replacement — the old frames are thin, the sills underneath have taken decades of condensation runoff, and setting a new unit inside them wraps good glass around a bad opening. On the 90s vinyl stock the frames are often still square and dry, so an insert replacement can be the honest, cheaper call. We recommend per opening, not per house.

One Story, One Fast Job

Here's the Valley's structural advantage: almost everything is single-story. On a rambler, every opening is reachable from the ground or a stepladder — no scaffolding, no second-story staging, no ladder work over entry roofs. That compresses a whole-house replacement dramatically. Most Valley ranches we do are fully swapped, flashed, foamed, and trimmed in a single day once the windows arrive, working one opening at a time so the house is never standing open. That same efficiency makes winter installs practical, and winter is often when the frost on the old frames is making the case for you.

Our Process

  1. On-site estimate — every opening measured and probed, insert vs. full-frame recommended window by window. Free.
  2. Written spec — frame material, glass package, U-factor, colors, and grid options in writing.
  3. Ordering and permitting — units are built to order; we file any required permits with the City of Spokane Valley while they're in production.
  4. Installation — one opening at a time, flashed into the wall, foamed, and trimmed; most single-story homes finish in a day.
  5. Walkthrough — every sash operated with you, inside and out, before we leave.

FAQs

Why are my 20-year-old vinyl windows already fogged?

Full-sun exposure on open Valley lots cycles the glass hot and cold daily, which fatigues the seal between panes years early. Once the seal fails the fog is permanent and the insulating gas is gone — the fix is a new unit, not a cleaning.

Can I stop the frost on my aluminum frames without replacing them?

Not really. Lowering indoor humidity reduces it, but the frame itself conducts cold — the metal will always be the coldest surface in the room. Replacement with a vinyl or fiberglass frame removes the cold surface entirely.

How fast can you replace every window in my rambler?

On most single-story Valley homes, one day of installation once the units arrive. The wait is manufacturing — built-to-order windows typically take several weeks, so we order first and schedule the install date with you.

Do window replacements need a permit in Spokane Valley?

Sometimes, depending on whether opening sizes change. Permitting runs through the City of Spokane Valley, and Domex handles it either way.
