Repair failed window seal

$200-$1,500 Est. time: 1.5 - 2hrs Low

Tasks and Notes

Failed seal in center bedroom.


The center bedroom window seal has failed. Double-pane windows typically consist of two panes of glass with argon gas sealed in between them to help insulate the home. Failure occurs when the seal between the two panes is compromised and the argon gas escapes.

Failed window seals result in moisture, visible as condensation, between the window panes that can lead to mold. This is not a short term concern, but we recommend eventually repairing or replacing the window..

Failed seals can sometimes be professionally repaired by having the moisture removed, argon gas replaced and the window resealed.

If Not Addressed

Failed windows are visually unappealing and also increase energy costs due to their compromised ability to provide insulation. Note, however, that a failed double-paned window is still much better than a single-pane window.

Estimated Costs

Repairing the window could cost between $200-$500. The more expensive route is replacing the window entirely. Given that only one window would need to be replaced the project could cost between $1000-$1500. These prices will fluctuate based on the actual conditions the professionals encounter. Request quotes from at least 3 professionals.
