Casement Window Replacement in Denver, CO
Casement windows swing open like a door and press tight against the frame when closed. Colorado Glass & Mirror installs Milgard and Pella casement windows in Denver homes, as full-frame replacements or glass-only repairs. Call 720-706-4572 any hour for a free measure.
A casement window is hinged at the side and opens outward with a crank. It seals tight when closed and catches side breezes well. Colorado Glass & Mirror installs Milgard and Pella casement windows across the Denver metro and will tell you whether you need a full-frame replacement.
Casement Windows for Denver homes
When you close a casement, the sash presses against the frame, which gives a tight seal against Denver wind and cold. The whole sash opens, so you get more airflow than a window that only opens halfway. A crank makes them easy to use over a kitchen sink or behind a counter, where a hung window is hard to reach.
See all window stylesWhich replacement fits your casement window?
Casements need clear space outside, since the sash swings out, so we check walkways and porches before choosing them. They are also a common upgrade from older aluminum or wood windows. Failed seals can be fixed with an IGU replacement. Damaged frames or hardware that no longer fits usually call for a full-frame replacement.
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.

Why Denver homeowners call us
Casement Windows questions answered
Are casement windows more energy efficient than other window types?
Casements often seal very well because the sash presses into the frame when you close it. Real efficiency also depends on the glass and the install. We install Milgard and Pella windows with Low-E glass and set each unit square and sealed, so the window performs the way it should.
Where do casement windows work best in a Denver home?
They work well over kitchen sinks, in hard to reach spots and on walls that catch the breeze. Because they swing outward, they need clear space outside. We check your walkways, porches and landscaping before we recommend a casement for each opening.
My casement window crank is stiff or broken. Do I need a new window?
Not always. A worn crank or hinge can sometimes be repaired. If the frame has warped, the sash no longer closes tight or the glass has fogged, replacement makes more sense. We inspect the window and give you an honest recommendation with a clear quote.
