"We recently had 8 sliding windows installed. The crew was courteous, efficient and cleaned up all debris. In addition to that they cleaned the windows after completion. Anthony was our salesperson and gave a good presentation and answered questions before and after accepting the contract. Pricing was reasonable. I especially would like to comment on their office manager, Diana. She was a pleasure to deal with and has to be a great asset to the company I would highly recommend."

"The professional (Mitch) tackled a difficult job. These were heavy patio doors, installed over 25 years ago, with damaged and worn tracking. They are now sliding easily and more securely with a new, secure lock. He is now putting a new lock on our front door. He is reliable, efficient and extremely competent."
