A garden window is a small projecting window with a glass top, glass sides and a shelf. It brings light into a kitchen and gives plants room to grow. Colorado Glass & Mirror installs Milgard and Pella garden windows across Denver as full-frame replacements.

Garden Windows for Denver homes
The glass top and sides catch light from more angles than a flat window, and the shelf gives room for herbs and small plants. Side vents let air move through. They are popular above kitchen sinks, where they add depth and brightness to a small space.
See all window stylesWhich replacement fits your garden window?
Because a garden window projects from the wall, the shelf, base and top need to be sound and sealed. Water at the base and rot at the shelf are common problems in older units. That usually means a full-frame replacement. If only the seal failed, an IGU replacement can restore a clear view.
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.

Garden Windows questions answered
Can a garden window replace a standard kitchen window?
Often yes, if the wall and framing can support the projection. We measure the opening, check the framing and confirm what fits. Some openings need a small adjustment, and we explain that in the quote before any work begins, so there are no surprises on install day.
Will plants be too hot in a south facing garden window?
Strong sun can heat a small glass box, especially in summer. Low-E glass reduces heat gain, and the side vents help air move through. Many herbs do well there, but sensitive plants may need shade in peak summer. We can talk through which way the window faces and which glass options suit it during the free measure.
Why is my garden window leaking at the base?
The shelf and base take water and sun over time, so seals and flashing can fail and the wood can rot. Fixing it means opening the unit up and often replacing it. We inspect the base and framing, then explain your options and cost.
