Problem with Moisture Trapped Between Glass on Windows

By:

Our insulated glass windows are approximately 25 years old and are getting moisture between the glass inside the sealed window. Should we contact the company that made them to see if they are defective? -Donna

Hi Donna,

If the insulated glass on your windows lasted 25 years before you had a problem, you’re doing pretty good. The warranty on the seal on insulated glass windows can vary from as little as one year to a limited lifetime warranty for as long as you own the home, so I would start by checking with the window manufacturer to see if yours are still covered.

If the glass is no longer under warranty, you can replace the glass in the window or the entire window unit. If you do decide to replace the glass or window, be sure the new glass comes with at least a 10-year warranty against the seals leaking.

To save energy and lower your utility bills, choose glass that’s filled with an insulating gas, like argon or krypton, and has a Low-E coating that is configured to minimize heat loss and gain in your area.

    I just bought a house in Georgia a with no appliances. The stove will be located against an outside wall. The house is 2 stories and is all brick. How should I vent the stove and microwave above it. The microwave will be attached to a cabinet that is attached to the outside wall. Should I go ductless?

    The company that did this procedure, Crystal Clear Window Works hasn’t responded to our recent calls or e-mails, so I’m not sure whether they are still in business or not. I don’t know of another company providing this service at present.

    Hi, We just purchased our home which was built in 1988; the glass between the panes are showing signs of moisture and we do not know how to go about doing the process you describe about drilling a hole. You mentioned cost lower than purchasing new glass. Around what price does it go for? Also we live in Inverness, Florida 34450 and I would need to know a dealer we could call to repair each window. We have 2 windows, one in the kitchen and one in the dining room also the sliders show moisture as well.
