How much does window repair cost?

Two publishers who actually differ

Our note, marked as ours, and it is a compliment rather than a criticism. On most of the subjects we cover, two guides printing similar numbers turn out to be printing the same numbers from the same upstream. Our window glass page documents exactly that, with two publishers giving an identical range and an identical average seven months apart.

Here they do not match. The averages differ by $8 and the floors by $50, which is our arithmetic. Small differences, but real ones, and real differences are evidence of two independent attempts at the same question. When they then land this close, that is worth more than any single number either of them prints.

So we would use about $400 as the working figure for a window repair, with more confidence than we have in most averages on this site.

The floor is where the useful information is

The $50 gap at the bottom is not noise. Fixr lists individual repairs starting at $50 to $100, and further items at $50 to $400, $70 to $175 and $75 to $200 depending on what is wrong.

Our reading, marked as ours. Those are the small jobs: a sash cord, a lock, a balance, a seal. They are the reason both ranges start far below their average, and they are the answer to a question people do not think to ask. If one window will not stay open or will not lock, you are probably looking at a two-figure repair rather than anything near $400. Get it priced before you let it become part of a replacement conversation.

When repair stops being the right spend

This Old House gives the rule plainly:

As a general rule, repair makes sense when the damage is isolated and affordable to fix. If the issue is widespread, affects performance, or continues to worsen over time, replacement is usually the better option.

Our reading, marked as ours. Three tests, and they are better than a price threshold because they do not go stale. Isolated means one window, one component. Affects performance means the window no longer does its job, which covers a failed seal fogging the glass or a sash that will not seal against weather. Continues to worsen means rot, which never gets cheaper to deal with.

Note what is not in the rule: age. A thirty-year-old window with one broken balance is a repair. A ten-year-old window with rot in the frame may not be.

What the alternative costs

The decision only makes sense against the replacement figure, and both of our window pages carry it. On the survey data covered on our window replacement page, a whole project is an order of magnitude above a repair, which is why a single repair almost always wins on cost alone.

Our reading. The case for replacing instead is rarely about this window. It is about the other fourteen, about efficiency, or about not paying a call-out charge five more times over three years. Those can be good reasons. They are just not the same reason as "this one is broken", and a quote that answers the second question with the first is worth questioning.

If the frames are sound and the problem is the pane itself, there is a middle option that neither extreme covers: our glass replacement page prices reglazing on its own.

What to take from this

1. About $400 is a well-supported average here, from two sources that are visibly not copying each other.
2. Small repairs start around $50. Price the single fault before anyone prices the house.
3. Isolated, performing, not worsening: repair. Fail any of the three and replacement enters the conversation honestly.
4. Age is not one of the tests. Condition is.
5. If only the glass has gone, reglazing sits between repair and replacement in both scope and price.
6. A bay window that has dropped or stuck is not an ordinary repair, because the structure carries it; our bay window page explains why.
7. A torn screen is its own small job, priced on our window screen page, and usually the cheapest thing in this section.
