How to estimate the cost to replace windows in 5 steps
Contractor pricing a job or homeowner reading quotes, the same 5 steps set the number.
-
Count windows by size and type
Tally every window: double-hung, bay or bow, picture, slider, casement, awning. Custom sizes push a window toward the top of its range.
-
Pick the frame material
Pella prices vinyl at $800 to $1,600 per window installed, fiberglass at $1,100 to $2,200, and wood at $1,100 to $2,200 or more.
-
Choose insert or full-frame
An insert sits in the existing frame. Full-frame removes it and, per Pella, costs 20% to 30% more. Older homes with rotted sills often need full-frame.
-
Price labor at your local rate
The BLS national mean wage is $31.55 an hour for carpenters and $25.02 for construction laborers (May 2025). Use your state’s rate from the table below.
-
Add permits, repairs, and contingency
Check your city’s permit fee schedule. Price rot repair as its own per-opening line, because you cannot see it until the old window comes out.
Average cost to replace windows by material

By project size, Pella’s whole-house guide puts 8 to 10 windows at $6,400 to $22,000+, 12 to 15 at $9,600 to $33,000+, and 18 to 25+ at $14,400 to $55,000+.

4 ways to lower the cost to replace windows
Moves that cut the bill, not the install.
Replace all at once
One visit avoids paying the crew to mobilize again for each phase, which Pella calls the most efficient way to replace.
Avoid full-frame unless needed
Full-frame runs 20% to 30% above an insert, per Pella. Use it only where sills or jambs are rotted.
Pick vinyl over wood
Vinyl starts at $800 a window installed against $1,100 for wood, and Pella rates it low maintenance.
Check credits before you bid
The federal 25C credit (30% of product cost, up to $600) covered windows installed through December 31, 2025, per ENERGY STAR. Ask your utility about local rebates instead.
