“GSI solved our biggest challenge by finding a slider with blinds that fit our space – they were very convenient, provided friendly and helpful service, and the project took only 2 hours to complete!”

“Just had Austin’s crew install 2 new exterior doors.  Their attention to detail was excellent, and this was the best door install job I have ever had since I have owned homes in 1989.”

“To the GSI crew: I just wanted to let you know how much I’m enjoying my new windows (last summer and this past summer).  Your guys did a great job installing them in a poorly built house and I appreciate it.  The front door too.”

“Thank you for the superior workmanship you provided with installing our windows.  From the first contact at the home show, throughout the appraisal process, to the finished product, your company excelled in providing a professional job.  You should be very proud of your employees, they went above and beyond our expectations.  They cleaned, painted, vacuumed and picked up every little piece of scrap.  Your company is the total package and is top among your competitors.  We will be referring you to our friends and family.  When we are ready to replace the rest of the windows, we will be contacting you.  Thanks again for a fabulous job.”
