How Much Does Window Repair Cost in Denver?

Most window repairs we do across the Denver metro run $750 to $1,500 per window, and $750 is our minimum, which applies per job. When one window's repair climbs past $1,500, replacing that window is usually the better use of your money. A new window installed runs $700 to $1,100 at the entry tier and $1,600 to $2,600 at the premium tier. We have no flat-rate repair menu, because the same symptom can be a small job on one house and a much bigger one on the next.

That's the answer. The rest of this guide covers how we price a repair, what pushes a window toward the top or bottom of that range, a simple way to check repair against replacement yourself, what Front Range weather does to windows, and when we'll tell you a repair isn't worth doing. If you already know what's wrong, our window repair page breaks down each problem and what window repair costs. We work across Denver, Adams County, where our shop is, and Aurora, and the pricing method is the same in all three.

Repair and replacement, side by side

You can't judge a repair price without knowing what the alternative costs. Here are both, per window, from our own pricing, current as of October 2026.

Look at the first and third rows. A repair can cost about the same as a new entry-level vinyl window. That surprises people, and it is the most useful thing in this guide.

Repair is not automatically the cheap option. It is the smart option when the window being saved is worth saving: a sound frame, a good sash, a premium or historic unit you couldn't match without spending far more. On a tired builder-grade window, a repair near the top of the range costs nearly what a new one would.

How we price a repair

No flat rates. We don't publish "seal repair costs X" or "balance repair costs Y," because those numbers would be guesses. A failed seal on a small, easy-to-reach unit and a failed seal on a large tempered unit over a staircase are the same problem at very different prices.

The visit is free. No trip fee and no diagnostic fee. Someone comes out, looks at the window, tells you what's wrong, and gives you a number.

Every window on its own line. If more than one window needs work, each one gets its own line on your written quote, so you can see where the money goes and decide what to fix now.

You get it in writing first. Before any repair starts, you get a full written scope and contract, the same as on any replacement job. Written quotes are good for 30 days. No same-day price, no manager calling with a special discount. A 50% deposit is due at signing.

Timing depends on materials. Repairs that need new glass take 2 to 4 weeks from when we order materials. Repairs using readily available materials, like trim, wood, or drywall, turn around faster. You get the timeline with your quote.

If we find something hidden, we stop. Sometimes a repair opens up rot or water damage nobody could see from outside. When that happens, we stop, show you what we found, and re-quote if the job has changed. We don't quietly expand the work and hand you a bigger bill.

What decides where your window lands

Check the math yourself

You can get a rough read on repair versus replacement before anyone comes out.

1. Count only the windows that are actually failing. Not the old ones. The broken, fogged, stuck, or sagging ones.
2. Build a repair range. Multiply that count by $750 for a low figure and by $1,500 for a high one.
3. Build a replacement range for the same windows. Pick the tier you'd realistically buy from the table above and multiply. One or two windows are priced on the same per-window ranges as a whole house.
4. Compare, then adjust for age. If the two ranges sit close together and the windows are near the end of their life, replacement usually wins. If they're good units with one isolated failure, repair usually wins.
5. Watch for the whole-house signal. If your count keeps growing as you walk the house, the question has changed. Our window replacement cost guide walks through that math.

Common repairs, and what each one involves

We can't put a fixed price on these. Here is what each job actually is, so you know what you're paying for.

Foggy glass between the panes. The seal has failed. Often the sealed glass unit can be replaced while keeping your frame and sash. Skip defogging services that drill and vent the glass; they hide the problem without restoring the seal. More on foggy glass.

A window that won't stay open. A balance failure: snapped sash cords on older wood windows, or worn spiral or coil balances on newer ones. Repairable when the part exists. More on windows that won't stay open.

Cracked or broken glass. Single pane gets re-glazed in the existing sash. Insulated units are replaced as a whole sealed unit. More on broken glass.

Drafts. Four different problems feel like a draft: air leaks, cold glass, aluminum frame conduction, and convection. The fix for one does nothing for another. More on drafty windows.

Stuck or painted-shut windows. Usually paint, swelling, track debris, or worn hardware. Sometimes a racked frame, which is a different conversation. A bedroom window that won't open is a safety issue. More on stuck windows.

Foggy glass, broken glass, and balances are what usually make people call us. During the visit we often find problems the homeowner hadn't noticed, and we'll point them out so you can decide what to fix now and what can wait.

What Denver does to windows

The Front Range wears windows out in specific ways, and those patterns show up in the repairs we do.

Altitude and sun. At 5,280 feet, sealed glass units built at lower elevations arrive under pressure stress, and UV is stronger than most of the country sees. Both shorten seal life and break down gaskets and weatherstripping. Our guide to high altitude windows explains why.

Daily temperature swings. A warm afternoon followed by a hard overnight freeze is normal here. Every cycle expands and contracts glass, frame, and seal. Over years, that opens seals and causes stress cracks that start at the edge with no impact point.

Hail. Hail cracks glass, dents frames, and tears screens. We often see homes where the roof or siding was replaced after a storm and the restoration company missed the window damage. If you've had a hail claim, have the windows looked at separately.

Dry air and wind. Dry air is hard on wood sashes and old glazing putty. Wind finds every worn weatherstrip and loose sash lock.

Older housing stock. Pre-1940 Denver homes have wood double-hungs with weight-and-pulley balances, often worth repairing. Post-war homes in Adams County and older Aurora neighborhoods still have single-pane and aluminum-frame windows, which usually aren't. The 1970s through 1990s double-pane units across the metro are where most foggy glass comes from right now.

Where cheap fixes cut corners

Questions to ask before you book anyone

• Is there a trip or diagnostic fee? (Ours is none.)
• Will I get a written scope and contract before work starts?
• How will the quote be broken out if more than one window needs work?
• What happens if you find rot once you open it up?
• Is tempered glass required in this location?
• Is the part still made, or are you finding a substitute?
• Does the repair carry a warranty, in writing? We do not warranty repairs. Our warranty covers installation of replacement windows and doors.

When we'll tell you not to repair

Sometimes the honest answer costs us a repair job. We'll tell you anyway.

• The repair runs past $1,500 on one window. A new window usually makes more sense.
• The frame is rotted or racked. You'd be fixing glass in an opening that's failing around it. Full frame typically adds about $200 to $300 per window over a retrofit insert, and it's the honest fix for a bad frame.
• The frames are aluminum. The frame conducts cold. Better glass in an aluminum frame leaves most of the problem in place.
• The window is single pane and comfort is the complaint. Repair restores function. It won't make a single-pane window warm.
• Parts are discontinued with no substitute.
• Many windows are failing at once. The whole run is likely at end of life. Most whole-home projects land at $8,000 to $20,000 for smaller homes and $25,000 to $55,000 for larger homes, and we'll show you that math instead of patching windows one at a time.

DIY or professional, honestly

Some of this is worth doing yourself first. It costs nothing.

Worth trying: clean debris out of slider tracks. Check that sash locks fully engage, since a misaligned lock leaves a gap along the meeting rail. Feel around the frame perimeter on a windy day; air at the wall edge points to exterior caulk rather than the window. Cover an exposed opening with cardboard and heavy tape from inside.

Leave to a pro: sealed glass units, tempered glass, cutting a painted-shut sash free, and balance replacement. These usually go wrong as a cracked pane or damaged sash, which turns a repair into a replacement.

If glass is broken and the opening is exposed, we can offer priority scheduling or a temporary board-up everywhere we work. Both carry a fee that depends on distance, materials, and the number of units.

Why a window company bothers with repair

Most window companies in Denver are captive dealers. One manufacturer, sometimes their own brand. When new windows are all you sell, every problem turns out to need new windows.

We're independent. We can source dozens of manufacturers, and the five we know best are Sierra Pacific, ProVia, Milgard, Pella, and Amsco. Nobody upstream needs us to hit a number on one catalog, so we can tell you when a repair is the right call and when it's money down the drain.

No four-hour presentation. No price that disappears when we leave your driveway. We'd rather be the company you call for the small job and trust with the big one.
