Very bad company. VERY DISAPPOINTED! I called them to get an estimate for a new shower door, and I got nothing but run around. I am a property manager and try to get a price on a new shower door, they want me to go to the house get the size of the shower (wall to wall), then when i called back and gave them the information they quoted me 650 dollars. But they need to come out to see the shower area to confirm the size, and he wants to have my credit card number in file, but when they came out he quoted me a different price, now they want 2,500 dollars for a new shower door. I told them it is too high, and I gotten other estimates for much lower price. Then he demand a $75 fee for his estimate which was never mentioned before, when I refused to pay him, he left very angry and very rude. The next morning i noticed he had charged my credit card NOT $75 BUT $90.10. (BE CAREFUL THIS PEOPLE ARE HIGHWAY ROBBERY) I am disputing this charge with my credit card company and i had to cancel my credit card to stop them using my card again illegally. read more

My experience couldn't have been better! I had some mirrors cut and delivered to a job site, Steve and Serg were on time, friendly and very professional, they gave me all the supplies necessary to get the job done and also gave me plenty of tip so I could get the job done right. I will definitely be doing business with Diablo Glass in the future! Thanks, Mike https://www.shanahanservices.com read more

Diablo Glass - Garage Gym Danville - Windows Installation Near Me - Concord, California

When they came out to give me a bid for replacement glass in a window, the representative kept taking other calls and trying to schedule other appointments. The appointment for measuring should have taken 5 minutes but because he was so distracted it was much longer. On the day of my appointment they sent a technician that had carpal tunnel and he apologized profusely that he couldn't perform the task. They then sent another person out who later told me I had paid in full when he completed the work to then get a call from the office stating I owed them the other $185. It was a 12"x12" pane and cost $360. I was disappointed in both lack of professionalism, communication and respect for me as a client. read more

HORRIBLE customer service at Diablo Glass! Had to replace a round glass table top. Taps Plastic suggested glass was the only way to go and mentioned Diablo Glass wasn't far away. The woman at Diablo Glass was unfriendly from the moment I walked in the door. She quickly took my order as if I was an inconvenience. I noticed the 3.9% CC service charge, and mentioned that I only had a credit card (do people carry checks or cash anymore??) and I'd prefer not to pay the service charge which amounted to an additional $25. Could I pay cash or check when I pick up my order in about a week? She said no, absolutely not; full payment is due upfront. It's our policy. I asked if I could leave a $320 cash down payment (about half the total bill and all I had in my wallet) and pay the balance when I picked up my order. She said no, we've been in business a long time and you'd be surprised how many people would do that and not return to pick up their item and pay the balance. I said I promise I will pick up my order as soon as it is ready and I will pay you. I jokingly told her I'd leave her my wedding ring to prove I will return. She was humorless, and again said no, it's our policy. You must pay upfront, it's on our website. i told her I didn't see the website, I was a walk-in so wasn't prepared with cash or a check, and could she please make an exception??? Again, no. Then she suggested I go home and get my checkbook-as if I live across the street??? Incredibly patronizing. She asked if I'd like to cancel my order, and I said no thank you, I guess I'm stuck. She processed the order on my CC , handed me the receipt, and said in a snarky sing-songie voice "Have a nice daaay!" I've told my family, I've told my friends. I'm a nice person, not combative. The interaction I had with this uncivil woman at this business left me deeply sad and disappointed. i dreaded returning to pick up my order a few days later. I will never go to Diablo Glass again read more

Whatever it is that you're looking for, stop your search right now and CALL THESE GUYS!!!! I came to them with an impossible task. I needed it done the same day. They under-promised and over-delivered!!! They are truly skilled craftsmen and professionals!! The end result was spectacular and they are very reasonably priced!! Great shop, I will be using them again in future for sure. Highly recommend Diablo Glass. read more

Thank you to Sergio and Sergio. Showed up on time. Got a lead time call, which I appreciate. They were professional, and they took little time to figure out how to fix our shower door. One of the doors sounded scratchy when moving it, and it was a bit sticky to slide. The shower door was a bit on the old side, but because they installed it, they had the parts to fix it. (Bingo! Haha!) So, they got the job done efficiently, were very neat, and were just nice folks all around. Since the job went fast, (and I asked...), they helped me get a stuck door "unstuck". Just all around good guys. My dad has been a customer since forever, so they are our go-to company for shower doors, etc. Thanks so much for all your help! read more

Tim was awesome! He took the extra time to repair our sliding door track so our new screen would slide smoothly. He was super kind, very professional, and did a great job. We highly recommend! read more

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! read more

This place is so friendly and quick! I've hated the look of our garage door windows since we moved, but we didnt necessarily want to buy a whole new door just because of something cosmetic. I discovered screws on the inside of the windows and realized the "starburst" pattern was just a panneling that could be removed. What I didn't know, was that the frame that held it together, opened on both sides and the glass in it fell out the front. Long story short. It fell out and shattered. I had no idea where to even find a replacement but I took another window out, (properly this time)and brought it into Diablo glass hoping they could help. Yvonne at the front desk was SUPER sweet and said she would check to see if they could do it right then and there. Literally, 5 mins later, a gentleman came through the back room with an exact copy of the glass. They saved my day! Thanks you guys! read more

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. read more

I'm a Mystery Shopper. You know, the person they send into businesses to check out how the employees are treating their customers? I "shop" over 1700 stores a year. I've seen the good, the bad and the ugly. Diablo Glass definitely falls into the last category. I listened as my husband placed an order for five glass shelves over the phone. The number of shelves, size, edge detail and price were repeated several times. When he went to pick up the shelves? They had the order written up as being for only three shelves. Now we get to wait another week+ for them to be ready AND we get to pay about 50% more than the quoted amount. If that wasn't enough? The two service people they have at the front counter (I use the term SERVICE people begrudgingly) have a snotty, imperious attitude that defies adequate description. Obviously no apology for the mix-up. LOL I will NEVER give Diablo Glass my business again. I don't care if I have to drive to the ends of the county, it would be worth it not to have to deal with these inept and rude people. Save yourself some time, aggravation and money. Take your business elsewhere! Jan C read more

I had Diablo Glass come out and give me a custom shower door for the Master Bathroom Shower. Workers came out and measured and gave me a quote. I put my order in and the installers came about two weeks later. They did a great job and the door looks terrific. I love it. read more

These guys are so great! I have had 2 different glass projects for them to take on. They are very accommodating and nice. Even during the pandemic, they shifted their shop for customers to come around the back of the building to stay compliant. The are amazing on follow through and communication. They are my go-to for all glass! read more

Being the cheap bastage I am, I bought Meg a dresser that lacked mirror glass in the frame. I knew I had to fix the situation before I attracted "aggro." I took the frame down to Diablo Glass. I explained what I thought I needed. They offered advice on how to save money by using a straight cut versus a curved cut in an area that wasn't noticeable. I was given a finish date. I showed back up on that date and was pleasantly surprised that he had, unrequested by me, near matched the wood on unnoticeable, behind the mirror, piece of wood that was needed to secure the glass in place. It was a little touch, but I would have noticed it and would have nagged at me for years. It's nice to have competence, even in the Bay Area, pay a visit every now and then. read more

I had two custom frames I needed mirrors in. One was over the vanity and the other was the door for the medicine cabinet. The medicine cabinet door needed a mirrors on the outside and inside. I dropped off my frames late Friday afternoon and Diablo Glass had them ready Saturday a little after noon. The price was competitive, the work accurate, the service great, and guidance of the front desk invaluable. read more

I was referred to Diablo Glass by Home Depot after they said that they didn't have a bottom seal or sweep to replace the broken and leaky one on my shower door. The employee who helped me quickly knew what i wanted and I had the piece in 30 seconds. I then told him that i was extremely unhandy and asked for and tips or help he might give me in first cutting the piece to fit my door and then installing it. After giving me a couple of great tips and in response to my expressed concerns about how to cut it to fit, he offered to go in the back and cut it for me. He graciously and quickly did so and did not want any extra payment for his work. To me, the work cutting the piece was worth more than the piece itself. Can't thank him enough for the "above and beyond" service. You don't find service like that anymore. Also, the young lady at the reception desk could not have been more pleasant and helpful. I'm not a big Yelper but did want to post this for people who are looking for superior service to go with their product. Ron read more

Great place, Richard was very helpful, and took the time to explain to me what was the best option for my wood slab project. Will be back read more

Great service and price; Richard and Yvonne helped me with my order (a glass shelf for my kitchen cabinet) and the order was done on time and it was a good quality. I was very pleased with this company. read more

So happy that I found Diablo Glass! During a bad storm my bedroom window frame was leaking water so badly, but no company would come out to fix unless they had originally installed the window (who keeps track of that?). Diablo Glass called back quickly and was able to get me an appointment right away. Pat was so great! He was super thorough looking at the issue and sealing the window. No more leak :) read more

I had mirror glass replaced. Excellent work done. Price was OK. I brought the broken mirror in just before Christmas and was told that, due to the holidays, it would be ready after New Year's day. No worries! I didn't hear anything from them for a while so, I called them to see what was up. I was told that they had called me more than a week prior to let me know that it was ready for pick-up. I received no call. One would figure that if the customer does not show-up within a week of being called that a second call would be appropriate. Other than the "lack" of service, they did great work. read more

Our business had an extremely successful experience with Diablo Glass in fixing our massive front glass door.

Richard was such great help getting our glass doors secure into our truck! Without him - they would have flown off the back! Thanks!!

Always outstanding service and quality. Pleasant and professional - makes everything so easy for the customers. Thank you so much!

Diablo Glass did an excellent sliding "glass" door replacement. We accidentally shattered our diningroom glass on our slider door. Lowes referred me to Diablo Glass. I was instantly impressed by Diablo Glass with their high level of customer service and 24 hour response time. Diablo Glass customer service is 5 stars! They called to confirm all appointments and always arrived on time too as promised. The work was repaired perfectly and professionally and the door is back to new!! So very satisfied and impressed with Sergio and the customer service staff at Diablo Glass. I would refer them to everyone needing any of their services! 5 stars! Thanks guys!!!

The seal that controls the legacy glass door to our business office had failed, and we were concerned about needing to replace it. The people at Diablo Glass were helpful, and promptly sent a rep to assess the damage. The rep was thorough (and wore a mask), and I felt confident that we were going to have it fixed properly. Once the quote was approved, a cheerful and focused technician came and replaced the needed parts and tested it thoroughly. The work area was left clean, the repair was explained, and we are very happy with the job. Thank you, Diablo Glass! read more
