Windows: costs, choices and hiring advice
Stop drafts, quiet the street and cut heating and cooling bills. Here is what to know before you get quotes.
What it costs
$300–$2,100 per window
Window replacement is priced per window, so your total depends on how many you replace and the frame material you choose.
- 5 vinyl double-hung windows, insert install$1,250–$4,750
- 10 vinyl double-hung windows, insert install$2,500–$9,500
- 20 windows, whole house, insert install$5,000–$19,000
Choices that change the price
- Insert or full-frameAn insert (retrofit) window fits inside your existing frame, so trim and siding stay put and labor is lower.
- Glass packageDouble-pane glass is standard.
- Frame materialVinyl is usually the lowest cost and needs little upkeep.
Problems and hidden costs to watch for
- Rotted frames and sillsRot is often found only when the old sash comes out.
- DisposalRemoval and disposal of old windows may not be included in the first quote.
- Lead paintHomes built before 1978 may have lead paint.
- Interior trim and paintFull-frame jobs can disturb interior trim and drywall.
Upkeep and lifespan
- Caulking and weep holesCheck exterior caulk every few years and keep the drainage (weep) holes at the bottom of the frame clear.
- Warranty registrationMany manufacturers require you to register the warranty.
