We've inspected every stage of seal failure a window can go through. Here are the problems our clients call us about most often.
Fog trapped between panes means the seal has failed and moisture has entered the insulated unit. Left unaddressed, minerals in that moisture etch permanently into the glass. We inspect the extent of the damage and recommend repair or replacement accordingly.
A failed seal lets insulating gas escape, forcing the HVAC system to work harder to maintain indoor temperature. The cost adds up every billing cycle the window goes unaddressed. We identify which windows are responsible before recommending next steps.
A perimeter seal failure lets outside air bypass the frame entirely, which feels different from a glazing seal issue but often points to the same underlying age and wear. We check both seal types during every inspection.
Mineral streaking between panes means moisture has been present long enough to leave a permanent mark on the glass. This damage cannot be reversed even if the seal is later repaired. We document the extent of etching so homeowners know what to expect.
Pressure changes inside a failed insulated unit can cause the glass to bow or distort slightly, creating a wavy appearance. This is a clear sign the seal has broken down structurally. We assess whether the unit can be repaired or needs full replacement.
South and west-facing windows experience far more thermal cycling from direct sun exposure, which fatigues seals faster than shaded windows. This pattern often surprises homeowners who assumed all their windows would age evenly. We prioritize high-exposure windows during every inspection.
Homeowners often cannot tell from the outside whether a seal issue calls for a quick repair or a full window replacement. Guessing wrong means overpaying or delaying a fix that is genuinely needed. We provide a clear recommendation with the reasoning behind it.
Most window seals last 15 to 20 years before wear becomes noticeable, and windows near or past that age are due for closer attention. Waiting until failure is obvious limits the options available. We track window age and condition to flag this before symptoms appear.
A buyer's inspection can flag seal issues a seller did not know about, which can stall negotiations or reduce an offer. Addressing it proactively with documentation removes that uncertainty. We provide a written report homeowners can share during a sale.
Prime Windows Toronto inspected our whole house and found two south-facing windows in the early stages of seal failure that I hadn't noticed yet. Getting ahead of it saved me from dealing with permanent etching later on.
I never understood why our west-facing windows always seem to go first until the technician explained the sun exposure and thermal cycling. Genuinely useful information, not just a sales pitch.
We have a lot of windows so the inspection ran about 20 minutes past the estimate. The technician from Prime Windows Toronto was careful and documented everything clearly, so I didn't mind the extra time once I saw the report.
Our windows are only 8 years old and still under warranty. Prime Windows Toronto documented the seal issue clearly enough that the manufacturer approved our claim without any pushback. Would not have known how to do that myself.
I expected to be told every window needed work but the technician was upfront that most of ours were in good shape and only flagged the two that genuinely needed attention. Appreciated not being oversold.
We scheduled an inspection before listing our house and it turned out to be a smart move. Having the documentation ready meant the buyer's inspector found nothing that surprised us during negotiations.
