About Us

GSI Complete Glass opened on July 15th, 1992 to serve the glass needs of the Deer Park and Spokane regions and beyond. Brian and Tony both worked in the glass business for years prior to opening GSI. Since the beginning, GSI has been committed to excellent service, top quality products, and the highest level of workmanship, giving them access to many higher-end and unique products in addition to the standard offerings from glass companies.

  • The "G" stands for Guarantee. We fully guarantee everything we do!
  • The "S" stands for Service. The quality of service that our customers have come to expect and deserve before, during, and after the sale.
  • The "I" stands for Integrity. You deserve the very best that we have to offer. That includes fair pricing, quality installation, and quality service.

"DOING IT RIGHT, EVEN WHEN NO ONE IS WATCHING."

What our customers say

“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!”

Chris

“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.”

Mark

“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.”

Melinda

“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.”
