What People Are Saying About Us

I did everything from my iPhone! Easy peasy!

The team at GCS was so easy to do business with. I did everything from my iPhone. I received quotes for my project with options to choose from. We scheduled appointments by text. Measurements were precise and the glass install looks great. When it was all done I made payments through an app on my phone. Easy peasy.

Very Accommodating!

Just had our new shower glass and frame installed and we are very pleased. Brendan and Tyler did a great job and we really appreciated them working around the other flooring project we had going on at same time. Very accommodating. The glass and framework looks great. I'm looking forward to using the shower tomorrow with the new look. VERY pleased. The company is very responsive, quick to come out and measure, and got the job done. Thanks!

– Steve Gerhart

A Great Experience!

A great experience from the first estimate, measuring and install. Really well priced and was surprised at how quickly the shower doors were delivered and installed an entire week early. Was very pleased with the entire experience from start to finish.

– Kathleen Ruhl

Super Fast Turnaround Time!

I found this company after looking at many top-rate glass companies in Denver and seeing that I had to fill out forms and wait for them to get back to me. Some took days, and others have yet to call or email back. GCS was easy to text in from the website and talk to someone and get a quote rather quickly with examples over the text message. Within a few mins, I had a quote and an appointment set! That's how you earn the business! Make the initial request EASY and prove what the client is looking for! They were on time for every appointment and were professional. The glass took a few weeks to arrive, but the team kept us in the loop via text and never missed a detail. We are so happy with our choice, and the glass looks fantastic! They even added a complimentary glass coating to keep the soap scum at bay for two years. I'm starting a new project and will use them again in the next few weeks! Highly recommend.

Look No Further!

No need to search any further for a new shower door. Not only is GCS very fair on pricing (believe me, I did my due diligence) but their customer service is out of this world (so rare these days). From working with Chance on pricing, Austin on installing, and Tom on measuring and follow through, everyone was extremely professional. Tom is a perfectionist in the best of ways. His attention to detail is reflective in the quality of work. Thanks team!

Best Experience Ever!

We had the best experience work with GCS Glass! We knew going in some of our product was on back order and would take awhile. We were so impressed with GCS Glasses communication! They always communicated what was going on every time they got an update. We never felt like they “forgot about us” because they were in constant contact. Their workers were great and professional. Price wise they were slightly cheaper than competing companies. We could not be happier with this company.

– Jessica Laue-Flint

Highly Recommend Company

I would highly recommend this company for your shower door. Brandon was quick to respond to my request for quote. He provided excellent details about the options and prices including pictures, all in text so was very convenient.

Professional staff, Outstanding installers

GCS Glass is the premier company in AZ. Professional staff, outstanding installers. I ordered 3/8" Starphire clear tempered glass, brushed nickel hinges and hardware to match my bathroom fixtures. Emily sent me a detailed invoice with photos of the hardware. This was the finishing touch to the custom bathroom I built. If you want the absolute best GCS will deliver.

– Mark Plennes

Smooth Process, Amazing Quality

We absolutely Love our Glass from GCS Glass Supply. The whole process went so smoothly and the quality is Amazing. Joe and Tim were very responsive each step in the process. The install by Junior and Camden was above our expectations. They were very polite, clean and provided quality craftsmanship. Many thanks GCS Glass. Best regards, Jim & Susan M.
