Sliding glass door dog door installation — Spokane Valley, WA

Last updated: September 24, 2026

What affects the price

The final price for installing a sliding door depends on a few key factors. First, the materials—like vinyl, aluminum, or wood—change the base cost significantly. Choosing double or triple-pane glass for better insulation also adds to your investment. The scale of the project matters, too; replacing an existing frame is usually cheaper than cutting a new opening in your wall. If you need custom sizing or specialized hardware, the total will adjust accordingly. We help you sort through these choices during your consultation. Exact pricing confirmed free on the call.
