Window Replacement Cost - Written Price Before Anything Is Ordered

How Much Does Window Replacement Cost in Austin?

Window replacement in Austin, TX typically costs between $550 and $1,850 per window installed in 2026, with most homeowners paying $800 to $1,200 per window for mid-range vinyl or aluminum frames with standard low-e glass. A full-house replacement of 10 to 15 windows generally runs $9,000 to $18,000, depending on window size, frame material, glass package, and whether the home sits in an older Austin neighborhood with non-standard rough openings. Labor and installation account for roughly 35 to 45 percent of the total cost, with the remaining portion covering the window unit itself, trim work, and disposal of the old sashes and frames.

If you’re replacing windows in a home built before 1990 in areas like Allandale, Hyde Park, or Crestview, expect to pay slightly more due to sill repair, lead-safe work practices, or custom sizing that older homes often require. Homes in newer developments like Mueller, Circle C, or Avery Ranch typically land on the lower end of these ranges because the openings are uniform and the framing is in better shape.

Window Replacement Cost Breakdown (2026)

Here is what we’re quoting for window replacement across the Austin metro as of 2026. These are installed prices, including the window, labor, exterior trim work, interior stop replacement, and haul-away of the old unit.

• Single-hung vinyl window (standard size, 36×48): $550 – $800
• Double-hung vinyl window (standard size, 36×48): $650 – $950
• Single-hung aluminum window (Austin original build, pre-2000): $500 – $750
• Fiberglass double-hung, low-e glass package: $1,100 – $1,600
• Casement window, vinyl, standard 24×36: $750 – $1,100
• Picture window (fixed, 48×60): $700 – $1,400
• Sliding window (36×36): $600 – $900
• Full-frame replacement (includes new sill, jambs, exterior trim, interior casing): Add $250 – $500 per opening over insert pricing
• Impact-rated window (PGT or CGI, required in many newer Austin builds with stricter wind codes): $1,200 – $2,200 per unit
• Labor-only charge for custom sizes or second-story work: Add $125 – $250 per window

Several things push a window replacement quote up or down in Austin specifically. Older homes in Central Austin neighborhoods like Travis Heights, Bouldin Creek, and Tarrytown often have wood-frame openings that have shifted or rotted over 40 years of Texas heat and humidity. When we pull an old window and find a rotted sill, the repair adds material cost and an extra hour or two of labor. Newer homes in Steiner Ranch, Leander, or Buda with clean framing and standard rough openings almost always come in at or below the mid-range numbers above.

Glass package is the other big swing factor. A basic single-pane or clear double-pane unit costs significantly less than a low-e glass package with argon gas fill, which is now code-mandated in most parts of Austin for new work and is what we recommend for any replacement. Low-e glass (a thin metallic coating that reflects heat back into the room in winter and out in summer) adds roughly $75 to $150 per window but cuts the solar heat gain coming through west-facing glass in an Austin summer by a noticeable margin. If your windows face west toward the Hill Country in a neighborhood like Westlake or Lost Creek, that upgrade pays for itself in air-conditioning savings within a few years.

What Affects Window Replacement Pricing in Austin

• Frame material. Vinyl windows are the most affordable and make up the majority of what homeowners in Austin choose. Aluminum runs close in price and is common in homes built from the 1950s through the 1980s across the city, while fiberglass and wood-clad units cost 40 to 70 percent more due to the material itself.
• Age of the home. Homes built before 1978 in Austin often contain lead paint on original window components. If we’re doing a full-frame replacement in an older home, the work falls under the EPA’s Lead Renovation, Repair and Painting rule, which requires containment and certified practices. That adds a modest line item to the quote, and it’s not optional.
• Window count and grouping. A single window replacement is always more expensive per unit than replacing eight or twelve at once. Mobilization, permit time, and setup get spread across more openings on a larger job, which is why our written estimates show a unit price that drops as the window count rises.
• Custom sizing. Austin has a lot of homes with non-standard window openings from small-build boom decades in neighborhoods like Barton Hills, Rosedale, and Northwest Hills. If the opening is not a standard 36×48 or similar common dimension, the manufacturer charges a custom-size fee that shows up as a line item on your written price.
• Impact-rated glazing. Homes in far west Austin, Lakeway, and the Hill Country corridor increasingly require impact-rated windows from manufacturers like PGT and CGI due to updated wind-load requirements. Impact-rated units carry a steeper price, and that is a code-driven cost, not a markup.
• Seasonal demand. Austin’s replacement season runs March through October, with a secondary bump in January when people file home warranty claims after the first hard freeze. Scheduling in the slower winter window can sometimes mean a shorter lead time, but our pricing stays consistent year-round because we quote written prices that do not shift with our workload.

How to Save on Window Replacement

The biggest savings come from planning the job in a single phase rather than doing two or three windows at a time. Spreading a 12-window replacement across multiple visits costs more in labor time, trip charges, and setup than doing all twelve windows over two or three days. If you are considering a phased plan, ask us to run the numbers both ways before you commit.

Here are a few practical ways to keep the total down without cutting corners on the window itself:

• Stick with standard sizes when you can. If your opening is close to a standard size, a good installer can adjust the framing to accommodate a stock window, which costs less than a custom order from the manufacturer.
• Choose vinyl with low-e glass, not wood-clad. Vinyl windows with low-e glass perform well in Austin’s heat and cost thousands less across a whole house than fiberglass or wood-clad alternatives.
• Replace windows before they fail completely. A window with a broken seal or a fogged pane is a straightforward replacement. A window that has been leaking for years and has rotted the surrounding framing costs more to fix because the repairs involve carpentry, not just a new window.
• Ask about grouping discounts. Replacing seven or more windows at once often qualifies for a better per-unit price. That is not a promotional gimmick; it reflects the real labor economics of a larger job.
• Get a written price before the work starts. A company that quotes a vague range and then revises the invoice at the door is not a company you can plan around. Our Kingswell Guarantee puts the full price in writing before any material gets ordered or any screw turns. You will not see a revised invoice at the door; you will see the number you were quoted, in writing, when the job is done.

FAQs – Window Replacement Cost

How much does it cost to replace a single window in Austin?

A single window replacement in Austin typically costs $550 to $1,200 installed, depending on the window type, size, and whether it is a pocket insert or a full-frame replacement. A standard vinyl double-hung runs $650 to $950, while a picture window or casement can push toward $1,400. For an exact quote on the window you are looking at, call (254) 322-3468 and we will give you a written number before anything is ordered.

Is it cheaper to repair a window or replace it?

For minor issues like a broken latch, a torn screen, or worn weatherstripping, repair is always cheaper at $75 to $300. For a failed seal, cracked glass, or a warped sash, replacement is usually the better financial move because a new unit costs $550 to $1,200 and comes with a manufacturer warranty, while repeated repairs on an older window add up without extending the frame’s life. If you’re not certain which applies to your window, call (254) 322-3468 and we’ll help you figure out what the window actually needs before you spend a dollar.

How much does a full-house window replacement cost in Austin?

A full-house window replacement in Austin, meaning 10 to 15 standard windows, typically costs $9,000 to $18,000 installed. Larger homes with custom windows, impact-rated glass, or second-story work run higher, while a ranch-style home with standard openings in a newer neighborhood like Lakeline or Pflugerville often lands near the $10,000 mark. The only way to know your number is a site visit and a written quote, which costs you nothing.

Do I need a permit to replace windows in Austin?

In most cases, a straight window replacement does not require a city permit, but if you are changing the size of the rough opening, adding a new window, or doing structural repair to the frame, the city of Austin requires a permit and an inspection. Our team handles the permitting on any job where it is required, and the permit fee appears as a line item on the written estimate you approve before work starts.

How long does window replacement take in Austin?

Most window replacements in Austin are completed in one to three days from arrival, with two-person crews able to replace 5 to 8 standard windows per day. If we discover rotted framing, a custom-size order, or lead-paint containment requirements on an older Central Austin home, the job can extend by a day or two while materials and inspectors line up. You will have a firm arrival window before we ever step on the property, and that window is in writing.

What does the warranty cover, and what happens if a window fails?

Our warranty is not a verbal promise. It is written, and it is handed to you at job completion, covering both the manufacturer’s warranty on the window unit and our installation workmanship. If something is not right within the guarantee period, you call us, and we return and correct it at no charge – no deductible, no negotiation, no revisiting whether the problem is ours. Our 365-Day Done Right Promise puts that obligation in writing on every job we complete across the Austin area.
