What a FANTASTIC job you guys came out and did. From the product knowledge your designer had and shared with us, to the customer service your office provided when we were curious how the job was coming along; we couldn’t have been any happier. Everything was above and beyond from service and quality. I would recommend your company to all of my friends, thank you guys again.
Gene Simmons (of KISS) and Shannon Tweed, Los Angeles, CAOur shutters and new vinyl replacement windows have beautified our home and really have provided an amazing insulation value. Although we had estimates from 2-3 other window type companies, we chose The Window Design Group because of their great reputation and because of your lifetime warranties. The installation was timely, the crews were great. Thanks so much!
I purchased 7 windows and 2 patio doors from The Window Design Group. The new windows were put in very well and straight and are much of an improvement over the old. Now with the new windows and patio slider doors, the outside elements stay out, as well as the outside noise. My electric bill has been reduced by more than $90.00 since having them installed. Keep up the good work. I will for sure call again in the future.
