WHAT WINDOW REPLACEMENT COSTS IN PHOENIX IN 2026

How much does window replacement cost in Phoenix?

Angi's cost guide for Phoenix, updated July 9, 2026, puts the average window replacement project at $4,652, with most projects between $1,926 and $7,788. Angi builds those numbers from what its customers report paying, and it puts Phoenix about 35% below the national average. Per window, Angi's Phoenix figure is about $600.

The number of windows moves the total more than anything, so here is Angi's Phoenix table:

These are published ranges, not a quote. For a national comparison, HomeGuide's window replacement guide (February 2026) puts a single-hung window at $450 to $1,500 installed and 10 to 15 windows at $4,500 to $22,500. Both make the same point: a house with eight standard sliders and a house with twenty windows, an arch and a patio door aren't the same job. An average only helps once you know what went into it. The rest of this guide covers what decides where your house lands, and our window replacement service in Phoenix page lists the nearby communities we also serve.

What's in a window replacement quote?

A window quote is four costs added together, and once you can see them, comparing two bids gets easier.

1. The window. Frame, sashes, hardware and glass. HomeGuide says the window itself is 65% to 75% of the total.
2. Labor. Taking out the old window, setting, leveling and sealing the new one. Angi puts installation in Phoenix at $95 to $285 per window, and HomeGuide's national range is $100 to $500.
3. Haul-away. Old aluminum frames and glass have to leave your property.
4. The extras. Stucco patching, interior trim, grids, obscure glass for bathrooms and special colors usually sit outside the base price.

When one quote comes in far below the others, one of those four is usually missing or cut short. Ask each company to list all four, so you're comparing the same work. A good quote also names the window maker and product line, the glass package, and how each opening will be installed, so there's no guessing later about what you paid for.

Phoenix window prices by frame material

Frame material is the biggest choice after the number of windows. Angi lists these Phoenix averages, and HomeGuide's national installed prices sit beside them:

Brand moves the price as much as material. HomeGuide lists these national installed prices per window for four common brands:

Each brand makes several product lines at different prices, which is why the ranges are wide. Compare the exact product line on each quote.

Aluminum costs the least, but Angi's own note on it explains the catch: it absorbs heat and passes it into the house. Vinyl gives you good insulation for the price, which ENERGY STAR's notes on frames also say, and our vinyl replacement windows page lists what goes into every vinyl window we install. Fiberglass costs more and is stronger. We compare the two side by side, with prices, in our vinyl vs fiberglass cost guide.

Glass, style and size: the other big price movers

Glass. Angi's Phoenix ranges are $300 to $2,000 for double-pane glass, $300 to $1,100 for Low-E glass and $600 to $3,000 for triple-pane. HomeGuide says a Low-E coating adds 10% to 20% to a window's price. In Phoenix the number that matters most on the glass is the Solar Heat Gain Coefficient (SHGC), which measures how much of the sun's heat gets through. Our guide to the best windows for Phoenix heat explains how to read it on the label.

Style. Windows that open cost more than windows that don't, and shapes cost more than rectangles. Angi's Phoenix ranges per window:

Size and access. Bigger openings need bigger glass. Second-story windows, windows over a pool or behind thick landscaping take more time and sometimes scaffolding.

How many at once. HomeGuide notes the cost per window usually drops when you replace them all together, because windows cost less bought in bulk and the crew sets up once.

Retrofit or full frame on a stucco home

On a stucco house, how the windows go in can move the price as much as which windows you buy.

A retrofit window fits inside the existing frame opening, and a flat flange covers the edge on the outside of the stucco. The stucco and the drywall stay where they are, so it costs less and goes faster.

A full-frame install takes the old frame out completely, back to the framing of the wall. The new window is nailed in and flashed, then the stucco around it is cut back, patched, textured and painted. It costs more because of that stucco work. It's the right choice when water has been getting in behind the old frame, or when you're changing the size of the opening.

When two quotes are thousands of dollars apart, check whether they're quoting the same method before you decide one is overpriced. We explain both methods in full, with what each one looks like on a Phoenix stucco house, in our guide to replacing aluminum windows in a stucco home. Our window replacement service page shows the steps of a typical job.

Do you need a permit to replace windows in Phoenix?

Usually not, if the new window goes into the same size opening. The City of Phoenix's list of work exempt from a permit (section 105.2 of the Phoenix Building Construction Code) includes replacing glass, sashes and doors in kind. Making an opening bigger or smaller is structural work and needs a permit. Angi puts permit fees for window work in Phoenix at $150 to $300.

Two rules still apply even without a permit:

• Bedroom escape windows. The city's emergency escape window guideline says a replacement has to meet the size rules in place when the window was first installed, and can't leave the home less safe than it was. If the opening gets bigger, today's code applies.
• Energy ratings. The code still sets limits on the glass, and the city's residential inspection checklist tells inspectors to check windows for the required U-factor and SHGC. Ask for both numbers in writing.

Scottsdale, Mesa, Chandler and the other Valley cities run their own permit offices, so your contractor should check with your city before the job starts. If you're in an HOA, its approval is a separate step, and it usually covers frame color and grids.

How the SRP rebate lowers the cost

If SRP is your electric company, its window replacement rebate pays $3 per square foot of window. As SRP publishes it in October 2026, the rules are:

1. You're a permanent SRP residential electric customer, and the home has had SRP service for more than a year.
2. The windows are ENERGY STAR rated, with a U-factor of 0.32 or lower and an SHGC of 0.23 or lower, and you give SRP the window's certified product number from the National Fenestration Rating Council directory.
3. A contractor licensed in Arizona installs them before April 30, 2027.
4. You apply within six months of the install, with the paid invoice and the contractor's signed form.

A 6 by 4 foot sliding window is 24 square feet, so that's $72 back, and ten windows that size come to $720. It won't pay for the job, but it's real money, and the windows that qualify are the ones that block the most heat anyway. SRP says it can change or end the program at any time, so check the page before you count on it.

The federal tax credit for windows is gone. The IRS says it covers improvements made through December 31, 2025, so windows installed in 2026 don't qualify.

How to compare two window quotes

Before you pick one, make sure you can answer these for both:

1. Retrofit or full frame? This explains most big gaps between quotes.
2. What are the U-factor and SHGC? Get the numbers from the window's label, not just the words "energy efficient."
3. Do the windows qualify for SRP's rebate, and will the contractor fill out and sign the form?
4. Are stucco patching, trim and paint included? On a full-frame job, that work is coming either way.
5. What warranties come with it? The maker's warranty covers the window. Ask what covers the installation, and get it in writing.
6. Is the company licensed? Look it up on the Arizona Registrar of Contractors site.

A fair quote also stays good for a reasonable amount of time. A price that disappears unless you sign tonight is pressure, not a price. When you're ready, ask us for a free estimate and compare it with the others.
