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 had an excellent experience with this company! I needed screens replaced on my condo windows. The gentleman who came to do the job was very courteous and the price was right! I would definitely do business with this company again!

First time using them, and found them to be very professional. Needed to replace broken glasses on security door....looked excellent! Plus had my grandbaby with me...they graciously carried frame to car and put in my car. It was truly helpful to me!!! Thanks for the great customer service 😊

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.
