We have condensation in about half of the 21 window units in our home and need to do something about this. We are seniors and will be moving to a seniors accommodation in a few years or longer if our health stays the same as it is now.
I have changed the glass on 2 of my windows in my home. 2 double pane 5'x5' glass pieces came at just under $600 delivered (took a bit of shopping around as we got prices as high as $2,000 for the same glass) And it took about 2 hrs each to install with a good friend.
The windows each would've been $1,500 for the cheapest and $3,000 for what we have, so we came at 10% of replacement cost.
But I am an experienced contractor, in your case you need to factor in labour costs.
How old are the windows? Perhaps there is some warranty on the glass. The units we install are guaranteed for life. Call your builder or window supplier and find out.
Best regards,
Andy
I had a few windows in my house repaired by having two holes drilled in opposite corners from exterior. Worked well.
However if the window is opaque due to the water in between defogging will not work. It only works well where the condensation has not etched the glass. You will lose a bit of R value. Its a lot less costly then having the window completely replaced.
Others may have differing opinions but thats been my experience. And not all companies who provide this service are equal. So do your home work and ask about warranty.
Jack,
I agree with some of the comments from Alex and Raymond. Repairing foggy windows is definitely a cost effective, and lasting solution if done properly.
There are two ways to go with it. You can either defog the windows (as suggested by Raymond), or change the sealed units (only the glass, not the whole window). Both solutions will save you thousands of dollars compared to a complete window replacement, and are way less intrusive. Of course, a proper assessment has to be done to ensure which solution would work best given the current condition of your windows.
