We used the Kerrock countertop to upgrade our kitchen countertops, and George and the team were extremely professional and a delight to work with. We went from an older dated kitchen to a extremely good looking and modernized kitchen with quartz countertops and sleek looking backsplash within few weeks. The work was done meticulously, and they were extremely open to few design ideas, including a window that was wrapped with the material. I won't hesitate to use Kerrock in the future and I highly recommend them.

Kerrock did a great, timely job providing kitchen and bathroom marble tops. Very professional and honest with more importantly no cost over runs. I would highly recommend them without reservation.

I am pleased to review this business! I was hoping to replace a 40 year old, cracked bathroom sink with a solid surface countertop and new sink. I searched for awhile to find a supplier outside of the big box stores, because the product selection is limited there and they really don't know the supply well. I found Kerrock Countertops and dropped in on them in hopes of at least getting some direction with the project. The office is at the rear of the parking lot and a little confusing to locate. George was working on something else, but stopped what he was doing to go over options with me, and we made an appointment for a few weeks out. I returned, and at the end of the appointment I had decided to have them do the manufacturing and the install of both the sink/countertop combination and a new shower pan and surround instead of my old, dated bathtub and tile. A few weeks later, George and his team came for the demolition. I had a cast iron bathtub that they managed to wrangle out of the small room and all the other debris. They were on time, friendly and cleaned everything up. A visit from my plumbers to install the new drain for the shower and then a few days later, they put my new shower and sink in. The material is lovely and they spent a lot of time getting the measurements just right. It's beautiful material... Livingstone -Bechamel color - solid surface. I was so pleased with the project that I hope to have some new countertops in my kitchen and bar. I definitely recommend this business. I've been really happy with solid surface counters. We originally considered stone products but I've had Corian for 11 years and it still looks great. Kerrock has a wide selection of choices. Very happy to have found them!

Totally professional. We had three quartzite panels, George worked with me to choose the best locations and grain direction. Our cabinets were out of level and they spent hours leveling them. We love the installation and highly recommend Kerrock. They use 3/4 plywood and Steel bars 3" x 3/4" by the depth of the counter to protect the overhangs where people will sit. Will get some photos of the installation later.

They aren’t the cheapest, but they are VERY GOOD. Zero regrets, good speed on the project, and we love the finished product. We kicked off our discussion with Marko at Kerrock in late October 2021 to redo our kitchen countertops in Los Gatos. Marko helped me get my head around the material options (we went for engineered stone due to appearance, durability, size of slabs we could get, lack of maintenance). I went home and drew up our kitchen layout and measurements and sent it back for an estimate. The estimate came back a day later and was substantially higher than one other I had gotten, but I could tell that the Kerrock folks would be paying a lot more attention to detail and all their finish products looked really tight and precise (they’ve done some work on big projects for exacting customers like Apple’s new HQ). We cook a lot and spend tons of time in our kitchen, so this was not something we wanted to take any gambles on. Our sink and faucet were not reusable, so I went through catalogs at Kerrock’s office with Marko and picked out new ones that they ordered and brought on the day of the install. We green lit the project and 10 days later the Kerrock crew showed up to rip out our old countertops to take back to the shop to use as an exact template. At the same time as the removal they put down the foundational plywood for the new ones, and spent a lot of time precisely leveling the cabinet tops. Living without a sink or cooktop for two weeks was painful, but obviously it’s just part of what you endure on kitchen projects like these. Exactly two weeks to the day after the rip-out they showed up to do the install, which took about five hours. The Kerrock guys cleaned up and went on their way leaving us with a completely new feel for our kitchen. It utterly transformed our space, and we could not be happier with the end result. From the edging to the seams to the leveling to the new plumbing, faucet and sink they installed…it was all on point, solid and gorgeous. Excellent craftsmanship. Again, they aren’t the cheapest out there, but they deliver top quality results. Our project took about 3.5 weeks from the estimate approval to finished install, which is definitely faster than I expected. We’re happy we went with the best and didn’t mess with the rest. :)

I did a research to find a good place to replace my bathroom countertop. I finally decided on Kerrock Countertops. I went to the showroom, and Marko helped me selected a nice looking Quartz stone and Christian helped me select the bowl. three days later, the installer Alonso come to the house to install it. It was amazing to me how careful how meticulously the installer did the job.I did not have to to do any repair or repainting!!! Now I have a beautiful bathroom countertop more than I expected! I might add the price is reasonable.....Dan 10/10/2019

Will make this review short: highly recommended. Not the cheapest, but reliable, effective, clear and very professional. From our 1st visit at Kerrock, going over how George would go at our outdoor kitchen countertop, to taking care of coordinating the granite slab we chose from Bedrosians, to the onsite template step, and finally the installation. Wrapped up in just 2wks, very happy, no regrets.

These people really check all the boxes. Communication excellent, meticulous workmanship, here when they were supposed to be, immediate response to small problem (which they pretty much fixed although it was outside their field of expertise). They installed a quartz countertop and new induction stove top for us. George checked every every aspect of the counter top installation as having the top a fraction of an inch too high would mean we wouldn't be able to open the windows and having it a fraction too low meant we wouldn't be able to use the drawer under the stove top. Other contractors said they couldn't cut our 25 yr old drop in sink to re-use for under the counter. As it is somewhat unique and is no longer made its loss would have been the one disappointment in the remodel. After a bit of discussion Marko said okay. It looks fabulous. They get 5 stars for that alone. But everything else was perfect. That from a perfectionist.

I searched around for about a month and a half before I found Kerrock. Most of the places I looked would only do the install. They would not do design or demo. Kerrock did everything. It was wonderful. I have never had a project go so smoothly in my entire life.

I hired them to install quartz countertops in the kitchen. George and Marko were both extremely communicative and professional in their communication. Of the numerous contractors I solicited, they gave, by far, the fairest estimate, the most responsive, and most transparent in terms of how the pricing broke down. They also fixed an issue with the countertop after installation. I highly recommend supporting them. I would certainly come to them again if I need additional countertop work done.

TLDR: would highly recommend working with Kerrock, they were communicative, punctual, experienced, and respectful. True masters of their crafts. I solicited and discussed quotes with several shops in the South Bay but Marko set Kerrock apart as he was informative, patient, and reasonable from the get go. He spent the extra time to detail the work required, what is and is not included in the quote provided, and even recommended material that would be suitable for my budget and needs. George and the team at Kerrock executed the countertop prep, installation, and plumbing perfectly . You can tell they've been in this business for decades and are constantly thinking 2 steps ahead. For example, my undermounted, workstation sink has a cutting board that needs to clear the counter top in order to sit on the built in ledge. While at the unit, George unboxed the sink and went through each accessory (cutting board, dish rack, drying mat, etc.) to understand their function and design. When he understood the cutting board would need to pass the quartz, that was the only accessory he took with him back to the shop. Thanks to things like this and the template he made, my plywood, quartz, and undermount sink all fit like a glove. When it came to plumbing, him and his team worked their magic assembling and installing my unconventional sink with weighted pulley system and side drain as well as connecting the dishwasher gap to the side of my choice (which wasn't easy considering there wasn't much space to work with the new disposal down there too). Also, special shout out to Tiko who installed my tile backsplash. He could not have made the install process any easier or worry free for me. He showed up, scouted a spot to set up his tile cutter and workstation, discussed details/expectations, measured to center the tiles, and then took his time looking and picking the right tile to install next as they are slightly varied in color. The quote provided was accurate and I appreciated that although my sink install took extra time, the additional time was not considered an additional bill. They did have to remove, reinstall and repair some of the old plumbing in the wall, which, unsurprisingly, was not part of the original quote. Marko and George both set realistic expectations and the additional price was reasonable. The experience and foresight demonstrated by everyone on the Kerrock team is why I am beyond pleased with the entire process of working with Kerrock.

The design, demo and installation of our kitchen counter tops and backsplash could not have been better than what Marko and his staff did for us. Everything was exactly on schedule and perfectly executed; no fuss, no mess, no problems. The price was right. The materials were excellent. The Covid masking was greatly appreciated.

I was pleasantly surprised to see how clean and inviting their office looks and feels. Marko explained to me the process and provided details about different options available for my project. I felt like I was talking to someone I knew for a long time. They know a lot about the specific of their business and trying their best to meet the customer's need.

We wanted our master bathroom's tile countertop replaced since we never liked it and wanted a solid surface like quartz or granite instead. I called a few contractors but most were hesitant to do the work, saying they were concerned our cabinets and/ or mirror may be damaged during demo. When I contacted Kerrock, I got a good feeling that George was very experienced with doing this work and would work carefully to reduce chances of damage to adjoining surfaces. Everything turned out beautifully, with no damage to mirror or cabinets! We chose a gorgeous Quartz material he had there in remnants, and are so happy with it. Demo took 2 hours, and we were very appreciative of the care George and his helper took in protecting our floors and stairs. Two weeks later, the countertop install was completed in 2 hours. The quartz was installed with it's pattern perfectly continuing up the backsplash. Done to perfection! Highly recommend Kerrock, and George is a really nice guy too.
