Window replacement is priced per opening, not per house, and the same window costs different amounts in different markets. This section breaks the price into the parts a quote is actually made of, so you can tell which line you are being charged for and which ones you can change.
Almost everyone arrives at this subject wanting one number. There isn't one, and any site that gives you one is guessing on your behalf. What there is instead is a small set of decisions that between them account for most of the difference between two quotes for the same house.
What a price is actually made of
A quote for replacement windows resolves into five things. Knowing which is which is most of the battle when two companies give you numbers that are thousands apart.
- The unit itself — the frame material, the glazing package, the size, and whether it is a stock size or made to your opening.
- The install method — an insert replacement fits a new window inside the existing frame; a full-frame replacement takes the old frame out down to the rough opening. These are different jobs with different labor, and a quote that does not say which one it is describing cannot be compared to one that does.
- Labor — priced by your local market, not nationally. This is the line that moves most between two towns.
- What is found on removal — rot, failed flashing, an opening that is out of square. Reputable quotes state how this is handled before it is discovered, not after.
- Finishing — interior trim, exterior capping, disposal, and permits where your jurisdiction requires them.
Why the ranges here are ranges
Every figure on the pages below is taken from a named source and carries the date it was reviewed. They are published as ranges because that is what the underlying sources report: window replacement is priced locally, and a national midpoint would be confidently wrong for most readers.
Treat any range on this site as preparation for a conversation with an installer, not as a substitute for one. The number that matters is the one on a written quote for your openings, from someone who has measured them.
How to use this section
Start with the question closest to what you are actually deciding. If you are pricing a whole house, the per-window figures matter less than the install method and the count. If you are replacing one broken opening, the opposite is true.
Common questions
Can you tell me what my project will cost?
No, and nobody can without seeing the openings. This site publishes sourced ranges and explains what moves them. A quote requires a measurement, and we do not measure, quote or install.
Why do two quotes for the same house differ so much?
Most often because they are not quoting the same job. One may be an insert replacement and the other full-frame, or the glazing packages may differ, or one may exclude disposal, trim and permits that the other includes. The pages in this section cover how to line two quotes up against each other.
Do you get paid if I click through to a company?
Yes. This site may be paid when it refers a reader to a local company, which is stated on every page. It is also why the cost pages here carry sources and dates rather than one confident number.
