Window Glass Replacement Services
These are breakage jobs: glass that is cracked, holed or shattered. If your glass is whole but cloudy between the panes, that's a failed seal, and foggy window repair covers it.
Broken Single-Pane Glass
Single glass is the simplest repair: the broken pane comes out, the old putty or glazing bead is cleared, and a new pane is cut to size. In a wood sash the new pane sits on a bed of glazing compound, is held with glazing points, and gets a beveled bead of putty. The putty is painted once it skins over; the window restoration page covers the timing. HomeGuide's national range for a single pane is $150 to $400.
Broken Insulated Glass Units
A double- or triple-pane window holds a factory-sealed insulated glass unit (IGU): two or three panes, a spacer, a seal and often argon. Crack one pane and the whole unit gets replaced. The installer measures the unit, orders it made to size, and sets it back in the sash with new glazing tape or beads. HomeGuide lists $300 to $800 for double-pane glass and $500 to $1,200 for triple. Custom glass can take 2 to 6 weeks to fabricate. One catch: on older or discontinued windows, a compatible unit may not exist, and then the sash or window has to be replaced instead. That's worth asking before you pay a deposit.
Tempered and Laminated Replacement Panes
Some panes legally have to be safety glass: glass in and beside doors, glass by a tub or shower, and large panes low to the floor near a walkway. The tempered glass windows page gives the exact rules. Tempered glass breaks into small pieces; laminated glass has a plastic layer between its panes and resists shattering. HomeGuide puts each at $300 to $750. A replacement pane in one of those spots has to match the safety rating as well as the size, so we'd ask the installer to note it on the quote.
Emergency Board-Up and Temporary Glazing
A broken window in January can't wait two weeks for glass. The usual stopgap is plywood screwed over the opening outside, or a clear plastic or polycarbonate panel so the room keeps its light. It keeps snow and intruders out until the measured glass arrives. HomeGuide notes that after-hours, weekend and holiday glass calls often cost 50% to 100% more than standard rates. If the opening is secure and dry, waiting for a weekday visit saves money.
Glass in Basement, Glass Block and Storm Windows
Basement windows sit at lawn-mower height, so they take their share of thrown stones. HomeGuide lists glass replacement at $300 to $800 for egress windows, $300 to $1,500 for glass block and $150 to $400 for storm windows. With glass block, ask whether the old pattern can still be matched before agreeing to a patch. For storm panels, see storm windows, where repair of the whole storm unit is covered.

Window Glass Replacement Cost in Troy
These are HomeGuide's national figures from February 2026.
| Glass job | National installed range |
|---|---|
| Average glass replacement, per window | $300 to $650 (about $475) |
| Single-pane glass | $150 to $400 |
| Double-pane glass | $300 to $800 |
| Triple-pane glass | $500 to $1,200 |
| Tempered or laminated glass | $300 to $750 |
| Small pane, under 24 x 24 in | $150 to $350 |
| Large pane, 48 x 60 in or bigger | $600 to $1,200+ |
What moves the number: pane size, the glass package, safety glass, second-floor access and emergency timing. Bay, bow and curved units often use custom sealed assemblies. HomeGuide says glass-only replacement is uncommon there and may void the warranty.
Before You Replace Broken Window Glass in a Troy Home
Insurance. HomeGuide says most homeowners policies cover glass broken by a covered event such as a storm, vandalism or an accident, minus your deductible. Wear and tear isn't covered. On a single pane the deductible often makes a claim pointless.
Energy code. Michigan's energy code exempts glass-only replacement in an existing sash and frame, as long as the building's energy use doesn't rise. You can put back the same glass. We'd still upgrade a broken single pane to a sealed low-e unit where the sash can take the extra thickness.
Lead paint. Scraping putty from one sash in a pre-1978 house usually stays under EPA's small-job threshold (the lead-safe window replacement page has the numbers), but ask the installer how they handle it.
Glass or window. If the sash is rotted or the frame is out of square, new glass in an old window is money poorly spent. Look at window sash replacement or a new replacement window instead.
