A sliding window has one or two sashes that glide horizontally on a track. It suits wide, short openings and is easy to use. Colorado Glass & Mirror installs Milgard and Pella sliding windows across Denver and checks your frame before recommending a full-frame replacement.
Sliding Windows for Denver homes
There is no crank or lift, so sliding windows are easy for anyone to operate. They offer a wide view and a clean modern line, and they fit well in basements, kitchens and rooms with wide openings. Keep the track clear of dirt so the sash glides smoothly and drains properly.
See all window stylesWhich replacement fits your sliding window?
Older sliders often drag on worn tracks, leak air at the meeting stiles or have fogged glass. Fog can be fixed with an IGU replacement. A bent frame, failed track or aluminum window that leaks heat is a case for full-frame replacement. For basement bedrooms, we also check egress sizing before ordering.
Full-frame replacement
Replaces the whole window, frame included. Best for rot, drafts, water damage or a change in size or style.
IGU replacement
Replaces only the sealed glass unit. Best for fogged or cracked glass when the frame and sash are in good shape.

Sliding Windows questions answered
Why does my sliding window stick or jump off the track?
Dirt in the track, worn rollers or a bent frame are the usual causes. Cleaning and new rollers help in some cases. If the frame has shifted or the window is old, replacement gives a smoother and tighter result. We inspect the window and tell you which makes sense.
Are sliding windows good for basement egress in Denver?
They can be, when the opening is large enough. Egress rules set minimum clear opening sizes for sleeping rooms. We measure the opening, check the requirements and recommend a window that fits. Confirm local code details with your building department before you order.
Can new sliding windows reduce drafts?
Yes. Many drafts come from old aluminum or early vinyl frames and worn seals. A full-frame replacement with a new Milgard or Pella window, installed square and sealed, cuts air leaks around the whole opening. We inspect first so you know the cause.
