Repairing Insulated Glass Windows

Insulated windows have double or triple panes, using spacers to create an air pocket in between. The panes are sealed to protect the pocket which is sometimes filled with argon to help reduce heat loss. 

Insulated glass windows are framed in vinyl or wood, and occasionally aluminum. The price varies based on the labor required to remove the damaged glass from the window, replace it and restore the seal.

Seal Failure: Sunny Windows, Vinyl Frames 

When your window gets foggy, the seal on one of the panes has broken. Window are constantly expanding and contracting and those that get the most direct sunlight tend toward seal failure. Interestingly enough, vinyl frames also seem to be a factor because of their expansion properties.

A broken seal may seem cosmetic, but if moisture's getting in, heat and AC are getting out. Plus the moisture between the panes can eventually cause problems with a wooden sash.

Save yourself the cost of replacing an entire window. Have us come out and replace the pane as soon as you can.
