To whom it may concern;

I had your window and doors installed in December 2005.1 knew that they were good Because they felt heavy, but very easy to open and close. As the winter came on we notice the Boiler didnt come on as often. The proof was when at the end of the year we found out that we Used less Gallons of oil. Than came summer and had reduction of between 25% to 30% in our Electric bill. I think in 2-3 more years Ill recover all of my installation cost.

In January 2008 I took procession of a house in Florida, built by a very excellent Builder. This model house was originally built in 2005-2007 for $945,000.00. Due to the housing Situation I got it for a lot cheaper. Everything in the house is pretty top grade, but Ive been Spoiled by you, because the windows and doors dont come close to the quality of yours.

Thank You

Joseph & Joann G
