Passage Island Home Inspection | Don’t Sweat the Small Stuff

A Passage Island home inspection post with comments on a common failure mode seen in windows. Options as to what to do about it are discussed.

A window seal failure occurs when the space between a dual pane window is breathing the exterior air, rather than being closed-off. This results in fog or moisture accumulation on the interior surfaces.

But should this be a concern for the homeowner or buyer? The short answer is NO. It is strictly a cosmetic issue. If the purpose of the window it to open up a spectacular view, then certainly it’s irritating and a replacement is appropriate. However if the view is secondary and the purpose of the window is for daylight, then it can be ignored.

As to what can be done to correct it… nothing other than a complete replacement of the dual window pane, if the frame is still in good condition. If the window frame has aged poorly, then a complete window and frame replacement is required.

In this particular case on Passage Island, since the cottage’s occupancy is seasonal and only water taxi accessible, the hassle to replace the windows for cosmetic reasons is hardly worth the effort, in our opinion.
