Services
Custom Shower Doors
Diablo Glass creates bespoke frameless and semi-frameless shower doors using 3/8 or 1/2 tempered safety glass. Our expert craftsmen ensure perfect fit and finish with multiple obscure glass options and 24 KT gold-plated finishes available. Each installation includes optional polymer coating for easy maintenance and long-term durability in Concord, CA.
Mirrored Walls
We install custom mirrored walls in 1/8, 3/16, and 1/4 thickness options that create space illusions in any room. Our precision measurements accommodate out-of-square walls while maintaining perfect alignment with light fixtures and outlets across Alamo and Walnut Creek locations.
Safety Glass
Our safety glass solutions include tempered and laminated options that meet strict safety standards. Tempered glass shatters safely while laminated glass maintains structural integrity when broken, both providing enhanced security for residential and commercial properties in the East Bay area.
Cabinet Glass
We offer over 30 patterned and colored glass options for cabinet installations, from subtle textures to complete obscurity. Our team installs custom-cut glass in existing frames with beveled edges or face treatments available, serving homeowners in Danville and Pleasanton with quick turnaround times.
Polymer Coating
Diablo Glass applies a hi-tech polymer coating that seals glass pores to prevent staining from hard water and soap scum. This treatment lasts over three years while reducing cleaning maintenance by 70%, ideal for shower enclosures and glass tabletops in high-traffic areas.

Great customer service and communication. I had Window replacement in my kitchen garden window box. The Installer Nate was on time, very conscientious, and, did a phenomenal job measuring and installing the new glass. This is the 3rd time I've used Diablo Glass and was 100% satisfied!

I first went there in the mid 70's. The customer service was exceptional back then. Had my showers installed by Diablo glass in 1985. Great service then as well. Fast forward to 2022. I needed some weatherstripping that had worn out. They had the weatherstripping and they gave it to me for free! A great family business that has kept its old school family values in their business.

We had the exterior pane of glass break on our double pain window. I called in to get an estimate and they were friendly and helpful. They told me to drop the window off for official measurements and they'd order the glass. At drop off they took the measurements and matched the glass type and even offered me a Diablo Glass hat. One week later my glass was in and I dropped the window off for installation. 2 hours later my window was ready and looked as good as new. Would certainly do business again.

My first experience with glass shower enclosure for a custom build pan/ seat shower. I was absolutely thrilled from first contact to finished job? Initial call answered all my questions / gave some suggestions I had not thought of, and loads if project specific info. Bob came to measure and he also was polite, knowledgeable. Order in, and great communication. Install day again with Bob and assistant went smooth, clean and AWESOME job. I would recommend / I will use again. Thanks Diablo Glass

Needed piece of replacement glass to replace a weird size poster glass that broke. They did so quickly, compensating for my poor measuring skills to ensure the piece fit my frame. Thank you very much! Will head to Diablo Glass again if need arises. *****5 stars *****

The folks at Diablo Glass were responsive and easy to work with. Kathy in the office took good care of us. She scheduled Bob to come measure about 10 days out, then called to offer an appointment sooner when they had a cancellation. Then when we scheduled the installation (5 windows replacement glass), we were also able to get a quick appointment due to Kathy's diligence. The workers, Nate and Ezekiel, were respectful and hard working.
They showed up on time and completed the job in less time than expected. We had a rubber strip that needed replacing on our stall shower, and they took care of that as well while they were at our home. All in all, we had a great experience and will highly recommend Diablo Glass!
