How much does a sliding glass door cost to replace?
Typical ranges, repair vs. replace, and what to look for in a new patio door.

Short answer: window replacement in Dallas–Fort Worth commonly runs from a few hundred dollars to about $1,500 or more per window, installed. Angi's Dallas cost data, updated in July 2026, puts the average at about $550 per window. A whole-house project usually lands somewhere in the thousands to the low tens of thousands, depending on how many windows you replace and which line you choose.
Angi's July 2026 Dallas figures give a useful starting point for whole-house projects:
Premium frames, large or specialty shapes, full-frame installation and repairs to rotted openings can all push a project above these ranges.
Compare quotes line by line, not just by the total. A low price can mean a lower-grade glass package or a shortcut installation. A high price should come with something you can see in writing. Be wary of “today only” discounts, which are a sales tactic.
Somewhat, but energy savings alone rarely pay back the cost quickly. Read our honest answer, and try the savings calculator for a rough estimate. If you want to spread the cost out, see financing.
Enter your square footage, windows and doors for a quick, broad estimate.
For most DFW homes, plan on a per-window cost in the hundreds to low thousands, and a whole-house total in the thousands to the low tens of thousands. The only way to know your number is a measured, written quote. We'll measure every opening, show you both lines and put the price in writing.
