The slab backing
Jimmy D.

I rarely leave negative reviews, but after years of frustration with Prefab Granite Depot, I feel compelled to share my experience. I hired them to install a waterfall-style counter back in June 2021. Barely a year later, the waterfall cracked for no clear reason. They came out again in July 2022 to repair it, but the job was subpar. I noticed that between the waterfall backing and the side of the cabinet. It wasn't flush at all. Which I'm assuming that it allowed the water fall to slide inward more than 90 degrees, thus putting strain at the joint. But I am not a professional installer. It took them until August 22, 2022, to actually address this crack and I was assured the issue wouldn't happen again, however nothing was done to fill the gap with sub board to prevent inward movement of the granite. Unfortunately, it did again crack. A third crack appeared on April 22, 2023. I reached out multiple times via email and phone, only to be completely ignored. No callbacks, no emails, nothing from their receptionist or customer service team. Then, in May 2025 -- the worst-case scenario happened -- the waterfall slab literally fell off the counter. It nearly injured my child, grazing his arm as it collapsed. This wasn't just poor workmanship; it was dangerous. I've given them multiple chances over the years to make this right, but the lack of accountability and disregard for customer safety is unacceptable. I would never recommend this company to anyone if this is still their current practice and to avoid at all costs.

My counter dropped after 4 months and they resuse to come back out and fix it.

BEWARE of Prefab Granite Depot! They're as crooked as a dog and and my counterops. They demonstrate zero business ethics as you can see by the pictures! They take no responsibility for their mistakes and will say all the problems are because of your house. Martha is a combative sales rep and has no interest in being fair or ethical in her customer service. The owner, Weiss, is no better. He doesn't honor their warranty. They reluctantly came out 3 times to attempt to fix their mistakes and my counters still aren't close to being even. Don't waste your time or money. They should be reported to the better business bureau.

We used the same quartzite throughout the house.

We love the quartzite we chose at Prefab Granite Depot! We had chosen 2 other slabs at another place but when we saw these, we knew these were the ones. They are so beautiful and we couldn't be happier. We loved them so much that we decided to do all the counters and the fireplace too. So happy we did!

Bar area.

Manuel was great. A true craftsman. Worked to make everything perfect. Highly recommend.

The final installed vanity

A good overall experience we picked the slab and they helped us make sure it was the one actually delivered. then they showed up, on time, quickly cut the vanity top to size and installed. they were respectful, they cleaned up and left. no hassle, no drama. I was pleasantly surprised to see it go EXACTLY as they had told us they are not the cheaper but they offer a great selection and deliver!

See all

Got a great deal on a large piece of scrap granite. It is working very well for me as a surface for tooling leather.

If I buy my Granite prefab tops, can you finish the fabrication to match my "L" shaped cabinets and do the installation?

Yes they can make them in any shape you want.

Can you just purchase the granite from them or do they have to install it?

Yes, you can purchase granite only, but we would rather install it because we are licensed and bonded, and sometimes we can charge you a prorated pice where we charge you a half slab only.

The company under this new upper management only cares about collecting their payments, not about quality work and customer service. PLEASE GO SOMEWHERE ELSE IF YOU WANT TO HAVE A GOOD EXPERIENCE AND BE HAPPY WITH YOUR KITCHEN!!! I contracted with them to reface my kitchen, and I have the following issues: * The cabinets do not match the bases. They even agreed with me and asked me for a paint bid, but then decided that they do match. * The laminate on the bases is already delaminating and it hasn't been a year, in some cases hasn't even been a month * Poor quality parts were knowingly used for warranty work, which resulted in them telling me they would need to come back before they ever even finished. At this point, I think the poor quality workmanship and use of broken materials is intentional. Additionally, they make it very difficult to get work done in the afternoon, as they state they only work until noon. See attached: Statement of information that details the change in management that took place January 2025 Screen Shot from CSLB License Board detailing that their license (639021) is subject to cancellation if a new qualifying person is not replaced by 4/2/25. Screen shots of emails for them requesting a paint bid and then stating that everything matches. Text messages with the now CEO and CFO detailing that installers only work 5 am to noon. Picture of the mismatch from the cabinet to the base with THEIR sample that also shows that the laminate doesn't go all the way to the top of the base. Picture of delaminating base.

They are a nice family business, and they have seamless coordination between the designer, cabinet installer, and stone installer. You won't run into a situation where gaps are left between subcontractors. 2. There were no hidden fees or unreasonable change orders. The final price was exactly what was initially quoted. 3. We chose Dekton for the countertop, which is fabulous but also known to be harder to fabricate and install. Our countertop was so masterfully completed; the grain patterns all matched up and fit together perfectly. 4. Marlene, the cabinet designer, has vast knowledge of products on the market, which gives her the capability to create ideas for non-standard options. 5. Carlos and the cabinet installers, were so multi talented, they did custom carpentry work per customer's wish, and also electrical connections and drywall finish, all with good quality. 6. Celia, the schedule controller had clear communication for the timeline, no over promise, all realistic, no back and forth changes, which makes it easy for the customers to plan their schedule around the construction. Overall, I wanted to highly recommend SD Cabinets and Stone to potential customers.

MBK assured me the project would take no more than three weeks. It took nine. The project was completed with the tenants living in the unit and MBK wasn't particularly respectful of the tenants. The workers often didn't show up on the days they told me they would. They didn't bother to use a barrier during the demo or cabinet installation, covering everything in the living room with a thick coat of dust. MBK also had a lot of turnover during the project and didn't bother telling me. At one point I was calling/texting the project manager for a week while being ignored because he had left the company without MBK mentioning it.
