Ameritech is a replacement company, so we won't sell you a repair. We will tell you straight which one you need. Start with the two-minute test below, or have us come out and check for free.
Ameritech Windows has built and installed replacement windows for Colorado homes since 1994. We don’t offer window repair, glass-only replacement, single-sash swaps, or hardware service. If your window can be fixed, a Denver glass shop will serve you better than we will, and we’ll tell you so on the phone rather than send a salesperson to your kitchen table.
What we can do is help you figure out which situation you’re in. Most people searching for window repair in Denver are looking at one of two things: a small part that has failed, which is a repair, or a window that has quietly stopped doing its job, which is not. The difference takes about two minutes to check.
Stand at the window and look for fog, haze, or water droplets between the two layers of glass, not on the surface. If it’s there, the seal around the glass unit has failed and the insulating gas that made the window efficient has escaped. That moisture is trapped inside the sealed unit, so no cleaning product reaches it, and no lasting reseal exists. A failed seal is a replacement, not a repair, no matter how good the frame still looks.
Denver is hard on seals. At 5,280 feet the UV is roughly a quarter stronger than at sea level, and a 40-degree swing between an afternoon and the following morning is normal. Every swing flexes the glass against the spacer. Seals that last 25 years elsewhere often fail here in 12 to 15.
Plenty of window problems are genuinely fixable, and you shouldn’t replace a good window for any of these:
If that’s your situation, you don’t need us. Search for a window or glass repair shop in Denver and ask for a quote on the specific part.
Patio doors follow the same rule. Rollers, tracks, handles, and locks are repairs. Fog between the glass, a frame that has bowed so the door drags or gaps at the top, or cold air pouring around the edges with the door latched are replacement signs. Ameritech replaces sliding and hinged patio doors along with windows, and a patio door is often the single biggest source of heat loss in a Denver home.
| What you’re seeing | Usually a repair | Usually a replacement |
|---|---|---|
| Fog, haze, or water between the panes | Yes, the seal has failed | |
| One cracked pane, window otherwise clear and tight | Yes, glass shop | |
| Broken crank, lock, or latch | Yes, hardware | |
| Drafts with the window closed | Sometimes, weatherstripping | If the frame has shifted or rotted |
| Several windows that bind, sag, or won’t lock | Yes, the frames are failing | |
| Single-pane glass or windows over 20 years old | Yes, on efficiency alone | |
| Sliding door drags on the track | Yes, rollers | If the frame is bowed |
Because every window we install is custom built and installed by our own crew, we take on projects of several windows at a time, typically three or more, rather than single-window jobs. If you have one bad window in a house full of good ones, a repair shop is the right answer and we’ll say so. If the fogged one is the first of several the same age, that’s usually the moment to look at the whole house once, while the crew is there.
Call (303) 444-1998 or use the quote form on this page. Not sure which side of the table you’re on? Send a photo of the window in the form and we’ll tell you before anyone comes out.
Not in any lasting way. Fog between the panes means the sealed glass unit has failed. The unit itself can sometimes be swapped by a glass shop if the frame is sound and fairly new; in an older window, replacing the whole window is the better use of the money.
No. We build and install replacement windows and doors. If your problem is a repair, we’ll tell you and point you toward a Denver glass or hardware shop.
Look for fog, haze, or droplets between the glass layers that don’t change when you wipe either side. That moisture is trapped inside the sealed unit.
Usually not. Our projects are typically three or more windows, because each one is custom built and installed by our own crew. A single window is a job for a repair shop.
A hardware or single-pane repair is cheaper than a new window. A failed seal, a rotted frame, or a set of 20-year-old single-pane windows costs more to keep than to replace once you count heating, cooling, and the next repair. The free assessment tells you which you have.
Maleah was the AWESOME BOMB, BABY!! 😂🤣😂Fantastic lady in helping us here!! She deserves a raise!! If not I will contact the police! 🤣🤣😂
Had a great evening planning our new windows with Meleah. She helped us figure out how to stay within our budget and still get the benefits of new windows. Great experience!
Very professional. Windows are high-grade for a reasonable cost. I would use them again for sure.
Maleah is fantastic, gave a very thorough presentation of the best 3 paned windows on the market. She was very knowledgeable, made us feel at ease, and confident about the product. I would work with her again if the opportunity arose.
