Replacement windows and doors in Phoenix, measured opening by opening.

Every Phoenix window job starts with the opening. Keep the size the same and the city's permit guide exempts in-kind glass and sash replacement. Change the size and you need a permit. We measure each opening, check the rule with the city and pick glass that holds back the afternoon sun.

Local housing

New windows for homes built from 1910 to now

Phoenix homes come from every era. The 1970s were the city's biggest building decade, at 18.6% of homes, followed by the 1980s at 17.3%. Historic Willo goes back to 1910, and Encanto-Palmcroft homes date from 1920 to 1952. We don't assume a window size from the year a house was built. We measure each opening and note which way it faces.

Measured, not assumed

Openings vary from house to house, even on the same street. We measure every one in person and size each new window to fit it.

Glass for the hot sides

The walls that face west and south take the longest sun. We pick glass by its SHGC, the share of the sun's heat that gets through, and lower is better here.

City rules

Permits, egress and historic districts

The permit line

Under the City of Phoenix residential permit guide, changing a window's size takes a permit. Same-size glass and sash work doesn't. If you want a bigger bedroom window, plan on a permit. We confirm each project with the city before anything is ordered.

Bedroom escape windows

Bedroom escape windows have size rules. The net clear opening must reach 5.7 square feet, or 5.0 on a grade-floor window. It has to be at least 20 inches wide and 24 inches high, and the sill can't sit more than 44 inches off the floor. It's section R319 in the 2024 code, and the city's inspection checklist lists it.

Historic districts

Willo, Coronado and F.Q. Story are three of Phoenix's 36 residential historic districts. Since July 1, 2011, replacing windows on their own there has needed no permit or Historic Preservation Office review, if certain conditions are met. Fold the windows into a larger permitted project, and they get historic review.

Why Vezina

Why hire our crews for your windows

Based in Estrella Village

Our office sits at 7310 W Roosevelt St, in the city's Estrella Village. When you call, you reach a team that works in your city, and we follow up within one business day.

Employees, not subcontractors

The people who install your windows work for Vezina. We don't use subcontractors, so one company answers for the whole job, from tear-out to cleanup.

City rules checked first

We confirm the permit question with the City of Phoenix before your order goes in, plus the historic district rules if your house sits in one.

Glass matched to each wall

A shaded north window and a west-facing slider don't face the same sun. We can match the glass to each wall, with extra solar control where the afternoon heat hits.

Licensed and insured

We hold AZ ROC #345515 and carry liability and workers' comp coverage. We've been in business since 2005 and have completed more than 100,000 homes.

One contract for the house

Windows, patio doors and attic insulation can all go under one contract, with one crew and one point of contact from start to finish.

FAQs: Phoenix Windows & Doors

Window and door questions

I want a bigger window. Will I need a permit?

Yes. The City of Phoenix residential permit guide requires a permit whenever a window's size is altered, and a bigger window does that. A same-size swap of glass and sash is exempt. We confirm the details with the city on every project and let you know before work starts.

Can I replace the windows in my Encanto-Palmcroft home?

Yes, with a few checks. Encanto-Palmcroft homes date from 1920 to 1952. The city's historic window guide, updated in 2019, asks for three things. New windows should fit the opening within half an inch and let in plenty of daylight, with a Visible Transmittance of 0.5 or more. They should also match the original grid pattern. A window-only job can skip historic review if certain conditions are met.

What do U-factor and SHGC mean on a window label?

Both appear on the NFRC label. U-factor rates how well the unit stops heat from passing through. SHGC rates how much solar heat gets past the glass. Lower is better for both. In Maricopa County, ENERGY STAR windows must come in at 0.32 and 0.23 or lower, in that order. The label also lists Visible Transmittance, which tells you how much daylight gets through.

Which patio doors handle the Phoenix sun?

Check the label before the style. In the Southern zone, ENERGY STAR sets separate limits for sliding glass doors and any door that's more than half glass. Those doors must hit 0.28 or lower on U-factor and 0.23 or lower on SHGC. That U-factor bar is tighter than the 0.32 for windows. We install sliding, swinging, multi-slide and folding glass doors.

Can I get an SRP rebate on new windows?

You may, if SRP is your utility. SRP's window rebate is $3 per square foot, for ENERGY STAR replacement windows at 0.32 U-factor and 0.23 SHGC or lower. They have to go into conditioned living space, installed by a licensed Arizona contractor, before April 30, 2027. New construction doesn't qualify, and APS lists no window rebate. See srpnet.com; we verified these terms in October 2026.

My house faces west. What should I ask for?

Ask about the glass first. SHGC tells you how much sun heat gets in, and ENERGY STAR's Southern-zone limit is 0.23. Low-E means a thin, clear metal layer on the glass that bounces heat back. On a hot west wall, Milgard's SunCoatMAX, with three Low-E coats, is worth a look. Milgard says it cuts solar heat gain more than two-coat glass. We'll compare labels with you before you choose.
