I went in to purchase part for my window and even though it was a part they dont carry, the sales person didn't try to up charge, he just told me where I could purchase online and save $30. That's service you don't get everywhere. I wish I was buying 300 windows just to do business with these guys.

I just had the windows in my home replaced. I couldn't be more pleased. The work was beautiful. The installer left my home and yard spotless. Yes, I paid 1/2 up front--but it was worth it. I paid $1,200 LESS than what two other companies wanted to charge me for the same quality windows. Further, Penny Window did it in 3 weeks time instead of the 4 to 6 weeks the other companies promised.
