WINDOW GLASS TYPES & UPGRADE OPTIONS
Insulated Glass Units (IGUs)
The standard in modern windows — two panes of glass sealed together with an air or gas-filled space between them. We replace failed IGUs that have become foggy, hazy, or lost their thermal seal.
Low-E Coated Glass
Low-emissivity coatings reflect heat back into your home in winter and block solar heat in summer. Upgrading to low-E glass during a replacement can noticeably reduce your energy bills year-round.
Tempered Safety Glass
Required by code in certain locations like bathrooms, stairways, and near doors. We replace tempered glass to the exact specifications your home requires.
Single-Pane Glass
Common in older Boise homes, sheds, and garages. We replace broken single-pane glass and can upgrade to dual-pane insulated units for improved comfort and efficiency.
Obscure & Privacy Glass
Textured and frosted glass options for bathrooms, sidelites, and entryways where you want natural light without sacrificing privacy.
Commercial Window Glass
Replacement glass for office buildings, storefronts, strip malls, and multi-tenant properties. We match your existing specs or upgrade to more energy-efficient options.

BOISE WINDOW GLASS REPLACEMENT FAQ'S
Can you replace just the glass without replacing the whole window?
Yes. If your window frame is still in good condition, we can replace just the insulated glass unit (IGU) inside it. This restores clarity and energy performance at a fraction of the cost of a full window replacement.
Why are my windows foggy or hazy between the panes?
Fog or haze between the glass means the sealed insulated glass unit has failed. Moisture gets trapped inside once the seal breaks. Replacing the IGU eliminates the condensation and restores your view.
How much does window glass replacement cost in Boise?
Pricing depends on the window size, glass type, and coating options like low-E or argon gas fill. In most cases, replacing just the glass costs significantly less than replacing the entire window and frame. Contact us for a custom estimate.
How long does window glass replacement take?
Most residential glass replacements are completed in a single visit. Custom IGU fabrication after measurements typically takes 7 to 14 business days.
What is an insulated glass unit (IGU)?
An IGU is the sealed glass panel inside your window frame — usually two panes of glass separated by a spacer and filled with argon gas for insulation. When the seal fails, the unit fogs up and loses energy efficiency.
Do you replace single-pane window glass?
Yes. We replace single-pane glass in older homes, sheds, garages, and historic properties. We can also upgrade single-pane windows to dual-pane insulated units for better energy performance.
Do you replace commercial window glass?
Yes. We replace insulated glass units and single-pane glass in office buildings, strip malls, retail storefronts, and multi-tenant commercial properties throughout the Treasure Valley.
What areas do you serve for window glass replacement?
We serve Boise, Meridian, Eagle, Nampa, Caldwell, Kuna, Star, Garden City, and surrounding Treasure Valley communities.
How do I know if I need glass replacement vs. a full window replacement?
If your frames are still solid and operating properly but the glass is foggy, cracked, or drafty, a glass-only replacement is usually the better and more affordable option. If the frame is rotting, warped, or damaged, a full window replacement may be the way to go. We'll let you know during your estimate.
