Single Hung Window Replacement in Denver, CO
Single hung windows look like double hung windows, with a simpler build. Colorado Glass & Mirror installs Milgard and Pella single hung windows across the Denver metro, as full-frame replacements or glass-only repairs. Call 720-706-4572 any hour to book a free measure.
A single hung window has a fixed top sash and a bottom sash that slides up. It has fewer moving parts than a double hung and is a common choice for bedrooms, basements and rentals. Colorado Glass & Mirror installs Milgard and Pella single hung windows across Denver.
Single Hung Windows for Denver homes
Only the bottom sash moves, so there are fewer parts to wear out and fewer places for air to leak. You still get a clean traditional look from the street. The tradeoff is ventilation, since the top of the window stays closed, and cleaning the outside of the fixed sash can take more effort on upper floors.
See all window stylesWhich replacement fits your single hung window?
Single hung is a good match when you want the double hung look at a simpler build, or when a window rarely needs to open fully. If the old frame is sound and only the glass has fogged, an IGU replacement may be all you need. If the frame is rotted or drafty, a full-frame replacement is the better fix.
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.

Single Hung Windows questions answered
What is the difference between single hung and double hung windows?
On a single hung window only the bottom sash moves, and the top sash is fixed. On a double hung window both sashes move. Single hung has fewer parts and a simpler build, while double hung gives better ventilation and easier cleaning. We can show you both options on site.
Are single hung windows a good choice for Denver basements and bedrooms?
Often yes. They are simple to use and seal well when closed. For a basement bedroom, check egress size rules before you choose a window, because some rooms need a window that opens wide enough. We measure and confirm what fits your room before we order.
Can I replace only the fogged glass in a single hung window?
Yes, when the frame and sash are in good shape. Fog between the panes means the seal failed, and an IGU replacement swaps the sealed glass unit without removing the frame. If the frame is rotted or leaking air, a full-frame replacement is the better long term fix.
