When you're getting a house ready to sell, you start seeing it the way a buyer will. That foggy pane in the dining room you stopped noticing years ago. The bedroom window that only stays open with a stick. The torn screen on the back porch. None of it is a big deal on its own, but together it can look like a house that hasn't been looked after, and that's the last impression you want.
Most of these are repairs, not replacements. Below: which window problems are worth fixing before you list, which ones may need more than a repair, and how to plan the timing so everything's done before the listing photos.
Should I fix foggy or broken windows before selling my house?
In most cases, yes. Foggy, cracked, and broken glass is easy for buyers to spot, and it can raise questions about how the rest of the house was maintained. Replacing just the glass fixes the look without the cost and disruption of new windows. If a frame is rotted, that's a different conversation.
Think about it from the buyer's side. They might walk through once or twice before deciding, and first impressions form fast. A crack in the glass or fog they can't see through is the kind of thing that sticks, even when the rest of the house is in great shape. If a home inspection notes foggy glass, a cracked pane, or a window that won't open or lock, those are usually the same targeted repairs.
You don't need to make the windows new. You need them to look clear and work the way they should.
Which window repairs are worth doing before you sell?
Focus on what a buyer can see or touch: glass they can't see through, cracks and breaks, windows that won't open, stay up, or lock, and damaged screens. These are usually quick, targeted repairs. Leave cosmetic upgrades and full replacements for the next owner unless a frame has actually failed.

A quick note on fog: if it's between the two panes, no cleaner will touch it. Moisture got inside because the seal failed, and replacing the sealed glass unit clears it. Our foggy window repair guide explains more. Sashes that slide down usually need new balances, which is a hardware repair.
Do I need new windows to sell my house?
Usually not. If the frames are sound, buyers mostly care that the glass is clear and the windows work. Replacing only the glass or hardware gets you there, keeps the trim and paint you already have, and avoids a construction project right before you list. New windows make sense mainly when frames have rotted.
Replacing windows before a sale can also bring work you didn't plan for, like new trim, painting, or siding repairs around the openings. And if you replace one or two, they may not match the rest of the house, which buyers can notice too. A glass swap keeps each window looking like its neighbors.
That said, some windows do need replacing. Here's how to read the signs:
- The wood is soft or crumbles when you press on it. Rotted wood can't hold new glass securely, so this one points to a new window.
- The frame or sash is cracked or split. This one depends. Minor cracks often still hold new glass safely, while bigger damage may not. Send photos of exactly where it's damaged and we'll tell you which it is.
- The frame is bent or warped. Same thing: it's situational, and sometimes we can make it work. Photos let us check before you decide anything.
A window that won't open, close, lock, or stay up is a different story. That's usually worn hardware, and most of the time it's fixable. It isn't a reason to buy a new window. Our guide to a window that won't stay up explains the usual fixes.
We don't sell or install full windows. If a window needs replacing, we'll tell you, and you can take that to a window company. For the full picture, read our guide on whether to repair or replace windows.
How far ahead of listing should I schedule window repairs?
Start a few weeks before your listing photos if you can. Regular-size clear glass is usually replaced in one visit, most of the time within 2 hours. But tempered, textured, colored, and Low-E or argon glass has to be ordered, usually 2 to 3 weeks after we measure. Send photos early so special glass has time to arrive.
A simple timeline:
- Walk the house and make a list. Open, close, and lock every window. Look for fog, cracks, and torn screens. Check the patio door glass.
- Take two photos of each problem window. One of the full window from inside, one close-up of the issue.
- Send them all at once. Start at https://2hourglass.com/start-service or text (267) 458-7879. We can price several windows together.
- Get your price. Photo review is free, and if the photos show what we need, we can usually send a price within minutes during business hours.
- Book the visit. Same-day or same-week appointments when available. If any glass needs ordering, we measure first and come back to install.
- Leave time for touch-ups. Wood windows with a special paint finish may need a little touch-up after the glass goes in.
Removal of the old glass, disposal, and clean-up are included, so the house is ready for showings when we leave.
A few terms you might hear along the way: tempered glass is safety glass that breaks into small pieces instead of sharp shards, and it always has to be ordered. Low-E glass has a thin, invisible coating that reflects heat.
Does the window warranty transfer to the buyer?
Yes. Double-pane glass we install comes with our Lifetime Seal Warranty. The warranty stays no matter who owns the property, as long as the glass is still in the same window, the sash is still in the same frame, and nothing has been altered. If the seal fails and fog shows up between the panes, covered labor and materials cost nothing. It doesn't cover impact or misuse damage.
That can be a helpful detail to share with your agent and buyers: the new glass comes with a warranty the next owner keeps. Details are at https://2hourglass.com/warranty.
How much do window repairs before selling cost?
Every job is priced on its own, based on the size and type of glass and what each window needs. Targeted repairs are usually a smaller job than new windows because the frames and trim stay. We don't publish price ranges, because a range would mislead: the price depends on your exact glass and window. In our experience, a glass repair usually costs about a third of a medium-quality full window replacement, and about a fifth of a high-end one. Send photos and we can usually send a price within minutes during business hours.
You'll get a fair price for the right repair, for the windows that actually need it, and nothing else. For what moves the price, see our guide to window glass replacement cost.
Do you work with realtors and house flippers?
Yes. We work with homeowners, realtors, and flippers, as well as landlords, property managers, and businesses, and everyone uses the same photo quote. Send photos of the windows that need attention and we'll price them, usually within minutes during business hours. No one has to meet us at the property just for a quote.

Frequently asked questions
Do foggy windows affect a home sale?
They can make a house look less cared for, because buyers notice glass they can't see through. Replacing the foggy glass unit clears it without replacing the window.
How much do window repairs before selling cost?
Each job is priced individually, based on the size and type of glass. Send two photos per window and we can usually send your price within minutes during business hours.
How long do the repairs take?
Regular-size clear glass is usually replaced in one visit, most of the time within 2 hours. Special glass like tempered or Low-E usually takes 2 to 3 weeks after ordering, so plan ahead of your listing date.
Should I repair or replace my windows before selling?
If the frames are solid, repair is usually the better fit. If a frame is rotted, or cracked or warped too badly to hold new glass, that window likely needs replacing, and we'll tell you.
Does the warranty transfer to the buyer?
Yes. Our warranty stays no matter who owns the property, as long as the glass is still in the same window, the sash is still in the same frame, and nothing has been altered.
What photos should I send?
For each window, one photo of the full window from inside and one close-up of the problem. That's usually all we need to give you a price.
