A window pane is fogged up, how much is it going to cost to fix it?

Asked by JLeslie (46155 points ) March 5th, 2013

A window on my house is holding moisture. The window has decorative crosses on the glass, I don’t know what it is called, but I assume it will add to the cost to replace.

How much will it cost more or less? Will it result in me having to touch up paint? They are wooden, painted windows. Is it easy to fix?

Is it a double pane nitrogen or argon filled window? How big is it? Can you see a pin hole in the outer pane? the cost can vary a lot. If it is a single pane normal sized window you can get it done for $15. If it is a large, gas filled it can be $300.

I am a cheapskate and only replace windows if they are broken. Sometimes a pebble is thrown up by the lawn mower or snow blower and it hits the window making a small cone shaped hole. I wait for a cool dry day and mix up some clear epoxy and dab it into the hole to seal it. I put magic tape over it to keep it in place until it sets up. The result is not perfect but it will last for decades.

Over the years I have broken every single basement window while mowing. One by one I replaced them with high strength plexiglass and have had no breaks since.

@LuckyGuy I’m selling my house so I assume it will come up on the inspection and I will have to address it. Your answer helps though, thanks.

Windows vary in price. Wood windows are more expensive to buy but easier to repair. Call a local glass company and get an estimate.

Would that be Georgian windows? If you’re selling I wouldn’t bother. If the sun is on the glass the condensation may disappear.

Open the window and drill a small hole into the bottom BETWEEN the two panes of glass. Blow dry air into the hole and you MAY be able to determine where the leak is while removing moisture from between the panes. If blowing air in seals the hole try suction instead. After you found the leak you can drill a second hole to circulate air and speed the drying (may take a couple days of constant air circulation). Finally seal the holes with clear epoxy. The cost should be $5 plus your time. You shouldn’t have to paint anything as no one will look at the bottom of the window. If you feel fancy you can blow in argon / nitrogen before you seal the hole which is also “almost free” if you have the gas anyway (for welding, etc) but most people don’t.

Okay, so, @muhammajelly, you are clearly very expert here, this is a wonderful-sounding answer. How about (though) if the seal broke years ago and there’s a kind of growing substance like mold inside the window between the panes? Can that be eliminated? Thank you my dear.

@susanc Anything is possible with enough work. I might ask myself though is the time it takes to fix this going to be with the gain? The answer could be yes depending but just consider if it is really worth it. Depending on the construction of the window you might be able to remove the wooden unit containing the glass without damage. You can commonly do it by tilting the window in for cleaning and then while horizontal tilt sideways until you can remove it from the track. After this you will have to disassemble until you get down to the unit containing the glass. This disassembly may require fixable damage as the units are commonly assembled with adhesives, etc. The unit containing the glass probably has an aluminum spacer filled with desiccant that the glass is adhered to. Measure it with a micrometer before you do anything to it. Then you can take a Dremel tool and a cutting wheel to cut the aluminum spacer in half. You can clean the glass and glue the two halves back together with a polyurethane/silicone based adhesive. Finally reassemble everything. It will probably take you a good four hours. Depending on the value of your time it might be cheaper to buy another glass unit.
