Windows cost guide

Window replacement cost factors

Window replacement costs depend on window count, size, frame material, glass package, trim work, and installation complexity. Custom sizes and damaged frames can increase labor and material costs.

Vinyl, fiberglass, and wood windows

Vinyl windows are often the lowest-cost replacement option. Fiberglass and wood typically cost more but may offer different looks, durability, or performance features.

Energy upgrades

Low-E coatings, gas fills, and triple-pane glass can raise upfront cost. Homeowners often weigh those upgrades against comfort, noise reduction, and potential energy savings.
