One cracked window shouldn't send you into a panic about your budget, but not knowing the real number probably will.
The cost of fixing a window ranges from $30 to $600, and most homeowners land around $392. The real number comes down to one thing: which problem you actually have, a loose latch is a $30 fix, a rotted frame is a $500 one.
Not all "broken window" problems are created equal, and that's exactly why the cost of fixing a window swings so widely. Let's break it down by what's actually wrong, so you know what to expect before a repair person even shows up.
| Problem | Typical cost |
|---|---|
| Hardware (latch, lock, crank) | $30 – $110 |
| Weatherstripping / drafty window | $40 – $400 |
| Sash cord or balance | $80 – $220 |
| Broken window seal (fogging) | $70 – $245 |
| Broken or cracked glass | $75 – $350 |
| Frame rot | $150 – $500 |
| Leaking window | $100 – $600 |
Notice how far apart these numbers are. A sticky latch and a rotted frame are both "something's wrong with my window," but they're not remotely the same repair, or the same bill.
This is a broken seal, not dirt. Trapped moisture between double-pane glass means the insulating seal has failed, and no amount of cleaning fixes it. Repair costs $70-245, or you can "defog" it for a cheaper cosmetic fix, though defogging won't restore the window's original insulation performance.
Usually worn weatherstripping or a gap in the caulk, not a reason to replace the whole window. This is one of the cheapest fixes on the list, often under $100 if it's just a weatherstripping swap.
Likely a hardware issue, a worn latch, a broken crank, or a sash cord that's given out. These are mechanical fixes, not glass problems, and they're usually on the lower end of the cost range.
This is frame rot, caused by water getting in over time. It's the most expensive repair on this list because it often means replacing part of the actual structure holding the glass in place, not just the glass itself.
Real example: A homeowner with two foggy double-pane windows and one drafty window might pay around $140-490 for seal repairs on the foggy windows, plus $40-100 for the drafty one, landing somewhere around $180-590 total. Compare that to a full window replacement at $400-2,000+ per window, and the repair path is clearly worth attempting first.

If you're facing frame rot, multiple failed seals across several windows, or a repair quote that's creeping close to half the cost of a new window, replacement usually makes more financial sense than repair. A single fix here and there is a smart move. Patching the same aging window repeatedly is where the math flips.
Repair is almost always cheaper for an isolated issue, a cracked pane, a broken latch, a failed seal. Replacement becomes the better value once a window has multiple issues stacking up, or the frame itself is damaged.
It's possible with a DIY defogging kit for cosmetic fogging, but a true seal failure that's let outside air in generally needs a professional to properly reseal or replace the insulated glass unit.
Only if the damage came from a sudden, covered event, like a storm or a break-in. Gradual issues like seal failure, drafts, or frame rot from age are considered normal wear and typically aren't covered.
Many window repair companies offer a discount for bundling multiple windows into a single visit, since it saves them a separate trip and setup for each one. It's always worth asking if you have more than one window that needs attention.
Most homeowners fund larger home repairs through the equity already sitting in their home rather than paying it all out of pocket at once.
