Fiberglass windows

Fiberglass frames provide a slim profile, stable material, and more finish choices than many vinyl lines. They work well where exposure and larger glass areas matter.

How pricing works

We compare fiberglass suppliers, frame profiles, colors, glass packages, and operation so you can decide whether the material fits the opening and the home.

We visit, measure, and review products and colors, then send one fixed-price proposal. The price depends on the project scope, selected materials, site conditions, and any related repair or finish work.

How it works

You get a clear scope and coordinated project communication from the first visit through completion.

Step 1

We visit, measure, and review products and colors with you.

Step 2

You get one fixed-price proposal covering the agreed scope, including affected drywall, trim, and paint.

Step 3

TruSeal coordinates installation and the agreed finish work to keep the project on track.

Step 4

Your completed package is covered by our 20-year workmanship warranty.

PNW climate advantages

The right product and flashing details can reduce drafts, manage rain at the opening, and simplify exterior maintenance.

Tradeoffs to consider

Frame depth, color, expansion, finish maintenance, glass area, lead time, and repair scope vary by product. We show those differences before you choose.
