    Brand new shower leaking, company refusing to fix it. Want to charge for a service call.
    Michael S.

    I have used this company before and honestly in the beginning they were very good and professional. The owner Andy recently lost many of his good installers and is now trying to learn how to install glass with his current installers, which are not only sloppy but don't do the job properly. Yes, the owner does not know how to install. After our client used his shower 72 hours after the shower door was installed we came across leaking. Everyone who reads this please note the company installed two shower doors on two different bathrooms. Upon noticing leaks in the master bath, I had looked into the finish product of the second bathroom shower door. Note the crew had to come back because the didn't install it plumb and blamed our tile installers. After they came back and brought a level they saw it was their fault. The second bath silicone seal was done sloppy, and there was gaps! And the icing on the cake??? The hardware we selected was black that came with black screws. The installers did not properly screw the hardware in and ruined the screws. But no worries, w little sharpie should do the trick!! pictures attached. When I asked Andy to please address this, he asked me to sign receipts of my already paid payments and said he would be charging for service call. I respectfully declined which was followed by Andy cursing at me for no reason. I have text messages of our entire conversation in which I sent photos of all the bad areas and he told me he won't do anything until I sign the receipt. He even threatened to put a lien on my clients house, which they are aware of after I showed them the text messages, and they will go directly to the CSLB to file a complaint if that ever happens. I hope this review helps the business owner Andy acknowledge customers and quality come first.

    Master bathroom steam shower ... glorious floor to ceiling glass!
    John J.

    I'd give Glass Definition 10 stars if I could! After installing 5 frameless shower enclosures and 2 frameless glass balcony railings (with one more on the way!) to our just-renovated home, we couldn't be happier. Andy was so friendly and knowledgable right from the first call. He inspired confidence! He came out right away to measure in order to give accurate quotes, and then final exact glass measurements once all of our tile was in. His team arrived and they were professional, quick, and courteous. The glasswork is incredible and impeccably done, and all that have visited our home have been extremely impressed. We have a floor to ceiling steam shower in the master bathroom, and it is stunning. All the other shower/baths look fantastic as well, and Andy paid attention to detail including what direction the shower door should swing as it opens. I was very appreciative of that! On top of all this, his wonderful wife Teresa handles the back office and was in constant communication with me throughout the entire process, which was so helpful and reassuring. I would not consider any other company for glass needs! Thank you Andy & Teresa!

    I've used Glass Definition twice for frameless glass shower door installations and each job went flawlessly. Competitive price, professional work, easy communication, and I got exactly what I wanted. I'd definitely use them again if I ever need glass work done.

    Andy and Teresa are so nice and very communicative. They offer a great product and a reasonable price. The glass is just beautiful. We chose a frameless door with nice hardware. They did such a great job on our master bathroom so we hired them again to do our main bathroom. I highly recommend.

    Mirrored wall surrounding my wife's new fitness barre (and the husband taking the photo)
    Joe M.

    On a Friday I was in search of a mirror to surround a ballet/fitness barre set up in my wife's home gym. I needed this done right away and it was Mother's Day weekend. Got several quotes and to my rescue came Andy the knowledgeable owner of Glass Definition. He came right out to my home and we discussed what I wanted and he explained how he could accomplish it. He gave me a terrific quote and told me his guys would be out Monday AM. His guys came out Monday morning (on time) and perfectly executed the job. The mirror was installed exactly as I had wanted by Andy's crew of 2. Four hours later they left the place spic and span. I highly recommend Glass Definition. You'd be lucky if they are available.

    Old Panel

    I needed to replace a few shower glass doors with clear glass. I called up Andy, and he was patient with me, describing what he could do, and how much time it would take. Once we agreed to a price, he came out and made critical measurements. After a couple weeks, the pieces were ready, and his team came out and installed the panels very quickly and very well. I can't recommend these guys highly enough!

    We called Glass definition, primarily, for our glass railings. They did an excellent job that we made them do the shower and toilet door. The employees are very nice and they do thE job fast and clean.. i would definitely recommend them.

    Let me start off by saying that this is the best glass company with the most competitive prices in the city! We needed a glass enclosure for our steam shower. We needed floor-to-ceiling glass, and a couple of their companies we received quotes from weren't able to execute our preferred design. Teresa and Andy were incredibly responsive, sweet and detail-oriented. They made sure we got the exact design we wanted, and even special-ordered a specific piece of hardware for us because they didn't have it in stock. They are a complete joy to work with. I am looking forward to working with them again for a future bathroom remodel, and will be referring any friends to them as well.

Michael Crooks was very responsive as a company rep and everything he quoted was delivered just as he said. The quality of the shower is excellent and we love the Koehler fixtures. We chose black on white to assist those with visual deficits and really like how they turned out! The fold down seat is also a plus for those with endurance challenges! The demolition andinstallation team of Jose, Gabriel and Jairo could not have done a better job! They were timely, efficient and professional. They demolished the shower and tub one day and took away all the debris. Then, the next day, they built the frame and installed the new walk in shower exactly as we requested. They were pleasant to have on our property and we're considerate in where they set up their workstation and parked their trucks. We did have a challenge posed by the installation day with company coming to visit us... And they worked out a mutually agreed upon date that met our needs. I highly recommend this company.. ask for this team of installers! You won't regret it!!

    I don't usually write reviews, but RELI truly deserves it…read more We hired RELI for a full window replacement project and from the very first interaction, the experience was completely different from every other company we spoke to. Unlike other contractors who were vague, pushy, or tried to upsell us immediately, RELI was transparent, patient, and incredibly knowledgeable. They explained exactly what products we were getting, why those products made sense for our home, and how pricing actually works in this industry. No mystery markups, no pressure tactics, and no games. Everything was clearly laid out upfront, which immediately built trust. The pricing was extremely competitive, especially considering the quality of the windows and the installation. We were quoted significantly higher by other companies for comparable (or worse) products. RELI clearly knows how to eliminate unnecessary overhead and pass the savings to the customer. Installation was smooth and professional. The crew showed up on time, protected our home, cleaned up thoroughly, and paid attention to the small details that most contractors overlook. The final result looks amazing -- our home is noticeably quieter, more energy efficient, and just feels upgraded. What impressed me most is that RELI actually cares about doing things the right way. You don't feel like just another job. They stand behind their work, communicate clearly, and follow through on everything they promise. If you're considering new windows or doors and want honesty, quality, and fair pricing without the usual contractor headaches, RELI is the company you want. I recommend them without hesitation and would absolutely use them again.

He apologized several times for the problems and did work with me to resolve some of the issues. However, the overall experience was much more stressful and time-consuming than it should have been. There were repeated scheduling and communication issues, installers were repeatedly late, and there were multiple delays. I often had to reach out several times just to get updates or confirm when someone would actually come. I had actually told Robert that I did not want to write a negative review and that I would give them another chance to finish everything properly. Unfortunately, even with that final opportunity, there were still issues. When the interior doors were completed, the locks were forgotten. They had to come back the next day, and I ended up installing the locks myself. The door stoppers were also delivered in chrome even though I had requested black. One of the interior doors is also cracked at the top. Robert told me that he would get me a replacement door, but the replacement was never delivered. There are also a couple of smaller finishing issues. One patio door screen is missing the lock, and another window has a loose bottom seal with tape that does not look properly finished. At this point, after everything that has happened, I will take care of these smaller issues myself because I do not want any more back-and-forth. There was also a financing issue. I was told that the financing would have 12 months with no payments, but when I submitted the financing, the actual terms were only 3 months with no payments. That was disappointing because I made my decision based partly on what I was told. Another issue was that the workers used our restroom even though they were specifically asked not to, and they left it unflushed. I will provide photos with this review so people can see the finishing issues for themselves. Overall, the final project is completed, and I appreciate Robert personally trying to work with me and make things right. However, the process involved too many delays, communication problems, scheduling issues, and finishing details that I had to deal with myself. I gave them another chance because I genuinely wanted to give them the opportunity to finish on a better note, but unfortunately there were still problems. I'm glad the project is finally finished, but based on my overall experience, I would not choose to go through this process again.
