Window replacement costs $400 to $1,500 per window installed, depending on the size, type, material, and brand. The window unit makes up 65% to 75% of the total cost, while labor makes up the other 25% to 35%.
Simple, single-hung windows and small picture windows cost the least to install, while large bay and bow windows cost the most.
Vinyl and aluminum are the least expensive and most common window materials. Wood window frames provide better insulation and an upscale look but cost more and are harder to maintain. Clad window frames are the most expensive option but last longer because they're made with vinyl-encased wood.
