Window Replacement FAQ

Answers to the questions Phoenix homeowners ask most about new windows, glass and patio doors.

How much does window replacement cost in Phoenix?

It depends on how many windows you're replacing, their sizes and styles, the frame material and the glass. Full-frame installs and custom shapes cost more than retrofit sliders. You get a written estimate after we measure.

Do I need a permit to replace windows in Phoenix?

City of Phoenix guidance says replacing a window in the same size opening on a single-family home generally doesn't need a permit, as long as conditions such as a solar heat gain coefficient of 0.25 or lower are met. Enlarging an opening needs a permit and inspection.

What kind of windows are best for Phoenix heat?

Dual-pane windows with Low-E glass and a low solar heat gain coefficient. Vinyl and fiberglass frames are both good choices for desert heat.

Can you replace every window in my house at once?

Yes. Whole-home window replacement is most of what we do, and many homes are finished in one or two days once the windows arrive.

My home was built before 1978. Does that matter?

Yes. EPA rules require lead-safe work practices by a certified firm when windows are replaced in homes built before 1978.

What does Low-E mean?

Low-E stands for low emissivity. A thin coating on the glass reflects heat while letting visible light through.

What is SHGC?

Solar heat gain coefficient: the share of the sun's heat that passes through the window. Lower numbers are better in Phoenix.

Retrofit or full-frame replacement?

A retrofit window fits inside the existing frame and is less work. Full-frame replacement removes the old frame to the studs, which makes sense when the frame is damaged.

Why are my windows foggy between the panes?

The seal on the dual-pane unit has failed. If the frame is sound, the glass unit can often be replaced on its own.

Vinyl or fiberglass?

Both handle Phoenix heat well. Vinyl is usually the budget-friendly choice; fiberglass is stiffer, stays stable in heat and can be painted.

Is my installer licensed?

Look up any contractor on the Arizona Registrar of Contractors website, roc.az.gov. Glass and window work falls under the R-65, C-65 and CR-65 glazing classifications.

Which parts of Phoenix do you serve?

We work across the City of Phoenix, including Arcadia, Ahwatukee, North Central Phoenix, Desert Ridge, Moon Valley and Maryvale.
