Failed Units

While the appearance of condensation, water droplets, and discoloration between the panes are the most obvious signs of unit failure, the largest concern with  failed insulated glass is the loss of energy efficiency.  Resulting in higher energy bills, the failed glass is no longer able to block the escape of temperature controlled air from your home.

Double paned glass develops condensation between the panes when the perimeter seal of the unit fails.  This happens for many reasons and can occur very quickly or slowly over time.  At Legacy Glass we can replace the glass unit only, while leaving your frame in tact.  All our insulated units are double sealed and carry a 10 year manufacturer warranty against failure.  In addition, we also provided a 1 year breakage* warranty and 1 year labor warranty at no extra cost. 

Luckily, this situation has a simple fix; at Legacy Glass, we replace hundreds of failed units every year for customers just like  you. 

Glass units consist of two panes of glass, the desiccant, (moisture absorbing gel) filled metal spacer bar around the perimeter of the glass, and the two layers of sealant.  The unit can be made up of many glass options including clear, low-e, tinted and/or safety glass to match your existing windows and meet building codes. 

We can also replace units with grids (or mullion bars); aluminum bars between the panes of glass that give the appearance of true divided lites.

*Excluding acts of god, commercial buildings and high risk locations such as golf course homes.

To get the grids to line up perfectly, we measured from edge of glass to center of grid and provide the manufacturer with a grid diagram for production. That is the only way to assure a perfect match.

One of our experienced glaziers will measure your units and provide an upfront price to replace them.  If you choose to proceed with the project, we will special order the glass to the size and specs of your specific windows.  Replacement glass is normally available a few days after ordering, at which we will schedule a convenient time to return and install.
