I built my house in 2005 and I have 43 windows I our home. The problems started before the paint was dry.
The window over the my front door fogged the first week we moved in. I had to fight to get them to come out. Then they wanted to me to pay for the painting of the new trim around the window.
For the last 8 years I have had nothing but problems. They don't even call back.
If you're looking for a new window look some were else. Just a side note you can't adjust them without tearing off the trim.
And you can't anyone to work there windows. This company don't care about thing more then your money
