Poorly constructed double pane windows can develop moisture in between the panes of glass. This is result of seal failure in the glass unit. When this seal failure occurs, the window loses it’s insulating value, and the clear glass can become foggy, moldy, and unsightly.


Broken or faulty rollers, locks, balances, and handles are a hassle. These problems keep you from being able to use and enjoy the windows in your home. Wood or aluminum windows are particularly prone to these problems because they tend to swell and stick with changing temperatures.
