Fogging Dual Pane Windows Can Be A Quick Fix, you may not even need a contractor.
We have all seen dual pane windows that have gotten foggy over time. It starts out as a slight discoloration that doesn't clean up after washing the windows. The problem is not on the outside, but on the inside of the window. That's right, between the two panes of glass.
It is caused by a failure in the seal that protects the gas injected between the two panes. The failure is usually in the rubber around the perimeter of the glass, the extreme weather can make the rubber hard and crack over time. The seal will also fail if one or both of the panes of glass has cracked, even slightly.
Over time, moist air gets in and little droplets of water begins to form in the inside of the glass, causing it to look foggy. Eventually the water droplets will get bigger and actually bead up and run down the inside of the panes.
This makes for a very ugly looking window. Since the window can not be cleaned or cleared up, it will always have a foggy look to it that will only get worse with time. Why not get this fixed and enjoy the view outside?
When the seal is broken, the window has lost it's insulation value. The gases injected at the factory creates an insulation value that helps keep the temperatures inside your home or apartment. If your window is foggy, you are losing money. It would be similar to leaving the window open. Not good.
So fix it yourself. You just need to bring the window to your local glass shop and have them order a new insert. It can probably be done without a contractor. If it is the sliding window, lift it out and bring it to the glass guy. If it's the stationary window, it can be removed with a screw driver and a "little bit of muscle". Of course, if the window is broken, use care or hire someone to look at it.
Many glass shops and contractors can do this for you, but that will cost you extra.
