5+ STARS!!! Special thanks to Carlos at Corner Stone Granite Design. I met with Carlos several times to discuss my kitchen upgrade. He was extremely patient helping me select my counters from choice of materials, layouts, prefab vs slab. Carlos is just so friendly and easy to talk to, while demonstrating his extreme expertise in everything there is to know about counters (materials, prefab vs slab, installation techniques, options). After picking out my quartz selection from his recommended supplier, Elite Stone Group, everything went like clockwork. Carlos and his team measured my kitchen, picked the counters from Elite Stone, cut to size in his warehouse, and installed to absolute perfection. Every cut, every hole, every edge was precise, and accurate. I appreciated how his team worked clean, with extreme workmanship and confidence. The end result was just absolutely stunning. I have received so many compliments on the counters from friends, family and contractors. The five star reviews Corner Stone has is for REAL. I would highly highly recommend putting complete trust in Carlos in installing your counters. As a pro tip, the counter selection is as important, if not more so, than your cabinets; recommend ALWAYs going with slab to get the least amount of seams, and matching of patterns across cuts. Doing a kitchen once and right is the approach to take. Lastly, Cornerstone pricing is excellent; comparing custom slab install prices to prefab installs offered by cabinet installers; is not apples to apples, so make sure to compare slab to slab install prices only. 5+ stars for Carlos and Corner Stone Granite Designs! I can't wait to do my wet bar with Carlos this year! Thanks Carlos for your expertise and help! read more

From initial contact for the estimate, measurement, install and communication everything was top notch. I had about 10 fabricators visited for an estimate and didn't find anyone like Carlos who is very detailed oriented, he noticed what others didn't notice and already knew what the scopes and level of details that customer wanted. There are some companies who only does fabrication and hire someone else for installation but Carlos does everything from picking up the slab, fabrication, measurement and install. I highly recommend Carlos for any countertop, tile work. read more

Carlos did an amazing job with our quartz countertops. He was very responsive and got the job done quick without sacrificing quality. He recommended 2 inch quartz which turned out amazing with our blue cabinets. The price was very good and in line with other quotes we received. But I feel like we got better service and more value for our money with Carlos/Cornerstone Granite Designs. I highly recommend him! Also we used Ombre Lavasa quartz from Elite Stone and they turned out beautiful! read more

Carlos made my kitchen and bathroom remodel such a smooth process. He responded promptly with a quote and his quote was very reasonable. He always returned my calls and texts in the same day and sometimes over the weekend too. He gave excellent suggestions for me and was so easy to work with. Since I was having my cabinet built by someone else, I had to time the work of the countertop and Carlos accommodated my needs. I highly recommend him to others as he is a professional and does quality work. I chose him because of his 5 start YELP reviews and I was more than pleased with his work and the quote. read more

Corner stone was excellent throughout the entire process. I initially made a appointment for a estimate and Carlos arrived on time and with samples for the kitchen quartz countertops. After three more estimates I decided to go with Carlos because of their price and communication. We decided on a installation day and time and his team arrived on time and got the work completed with a few hours. The work was excellent. Would not hesitate to use them again for future homes. read more

My general contractor referred me to Carlos. From the initial text message through the completion of the project, Carlos responded to all of my questions quickly and accurately. He offered to come on-site to review my current kitchen setup in order to provide an accurate estimate, which turned out to be within the range once all the costs were finalized. He finished a countertop replacement in a day and I appreciated that he kept my front yard area as clean as possible while he cut the countertops. Throughout the project, I could tell Carlos cares about the small details, and the final result shows. Thank you so much Carlos! House projects are often overpriced, delayed, and not the outcome you expect, but Carlos did a stellar job. I would highly recommend him for future projects and countertop work! read more

Looking for someone to replace my small kitchen counters, sink, faucet, and garbage disposal. I did some pricing at big box stores and assumed a private installer would cost more. Playing on Yelp I found Carlos. All the positive reviews seemed impossible but I thought it would be worth a try. I asked to be contacted, he got back to me quickly. I told him what I was interested in, we set an appointment and he was here right on time. I already knew I wanted quartz and the type of fixtures I wanted. He brought a multitude of samples. Gave me his estimate,,I about fell out of my chair when I saw the EXTREMELY REASONABLE price and told him then and there it was a go. We just had to wait about a week for my sink to arrive. It arrived, we set up the appointment for the install. He was right on time with a helper and they were ready to go. He arranged for a plumber to come in behind them and he too was right when Carlos told me he would be there. I do not know what to say. They were perfect. They were quick. They left the place as spotless as it was (well maybe cleaner) when they arrived. Pure quality work and commitment. I thought no way would he be done as quickly as he said he would,,they were done quicker. YOU WILL NOT find a better person for the job. He and his crew were amazing. BTW, I learned a little more about Carlos and how long he has been at this. DO not be fooled by 21 reviews and the company start date. He has been in the occupation for a while as has his crew,,he knew exactly what and how to do. CARLOS,,,I thank you and if anyone asks me,,I will send the to you. read more

We had quite a bit of work to do on our fixer-upper house that we just bought in Lakewood, with our handyman doing all of the work. He was going to install an overmount sink, but we didn't really love how they looked. So we switched plans (after we'd already bought our prefab quartz counters) then found out other companies would only work with you if you bought counter from them. Uh oh! Thank goodness I found Carlos and Corner Stone. He listened to our challenge and provided all of the solutions. He even went to Orange to pickup the counters, then cut them onsite at our home. No wait at all! Other companies had quoted days! We couldn't be happier with the work that he did and the help he provided in a really stressful situation. See pics below...his work speaks for itself and I highly recommend Carlos and his company for any project you have. Thank you again Carlos! read more

Normally I would view what he wrote about his Christian/family etc. approach cynically as manipulative. Now that the work is done and I've met him several times I'm a bit ashamed for my cynicism, I feel he is very authentic. Though the work was only recently completed, we looked it over very carefully and are completely satisfied. read more

Carlos the owner is awesome. Out of all the many fabricators and so called kitchen counter installers or even quartz warehouses he was the only one who said it was possible to make our large kitchen island off of a jumbo size quartz. He was very professional and reasonable. He kept us informed all throughout the process which I was very stressed because of everyone else saying we had to go with quartzite. Carlos and his crew came picked up the quartz from the warehouse in Anaheim that he recommended and they it and installed at my house. Great job Carlos look forward to working with you in the future... gracias! read more

We went to many different places and got different bids and found Carlos at Corner Stone Granite Design to be the best of them. He offers the most reasonable price and more importantly, was able to deliver what we wanted. What we wanted was a flawless Quartz counter top with a nice, thick edge with no seams. If you're shopping for countertops, be wary of low bids where the seams are visible on the edge. Please hire a professional like Carlos so that you can proudly show off your countertop. And Carlos showed up on time, every time. We really appreciate this since we've had other contractors who showed up really late or never showed up at all. Throughout the process, we kept changing our design plans with him and he was very accommodating and didn't show any frustration with our indecisiveness! The actual work was done in only a couple of days (one to demolish the current countertop and another day to install the new countertop) and the workmanship was excellent. Overall, if you are looking for a nice countertop job, do yourself a favor and contact him for a bid. He's very easy to work with and will deliver a nice, finished product that you will be fond of everyday. We live in the Cerritos area. read more

Very professional and affordable. Did an incredible job. They transformed my kitchen in to my dream kitchen. I have used this company for both of my bathrooms and now my kitchen. I would highly recommend!! read more

My husband and i used Carlos and his crew in a pinch as our contractor's fabricator walked off our job. Long story short he said the types of cuts and how we wanted to hide our seams were "too difficult." Well we reached out to a few folks and spoke with Carlos and from the very beginning he was VERY friendly and easy to work with. He came out the same day we reached out and had our countertops installed 4 business days later!! We couldn't be more thrilled with the amazing quality and ease of doing business with Carlos. Seriously, if you're looking for amazing quality at a great price you cannot beat Carlos!! He should get a 6th star for the fact that he literally saved our kitchen from delays and our contractor! We are looking to do our bathrooms soon and going to use Carlos again! read more

Carlos came by quickly and gave me an estimate. His rate was fair, not cheap, but not expensive. He scheduled a day to do the job, but finished another job sooner so he called and came over the day before we had him scheduled. He and his wife came over and together knew exactly what to do. I wish I had taken better pictures, but only have this one to share. I would definitely use them again and encourage others to. read more

Carlos, the owner.... He is something else. Very reliable, keep appointment time sharply, seeking the best way for his customer. He is not only a businessman but caring person. We had a problem to purchase counter tops from MIS(in Aneheim : #1 quality quartz) due to increased price. I got 5 of prefab and 1 slab from there at the beggining of remodeling but somehow I needed 1 more prefab. But when I was about to buy one more, the price has been increased. At that moment, he instantly contacted to his designer and asked if she has a same one with reasonable price. Luckly she had it with $100 less price. In this case, he could just give same price which I originally purchased from MIS and save $100 for his pocket. But he didn't do that. He honestly talked to me and saved MY Money rather than putting extras in HIS pocket. Regarding to His professionalism of work, there is not needed to talk about it. Because he knows his job and do his best! If you have any concerns about your counter top, just toss you worries to him He will be willing to take it and do for the best result!!! You will not regret for your decision with him. Lastly, the price? He would always give you a fair price. Very reasonable. Every single penny you will use for him, it would be worthy!!! read more

We were remodeling our kitchen and looking for someone to install the countertops in our kitchen and island. We contacted multiple people that were highly recommended and none responded or were extremely flakey. I reached out to Carlos after reading reviews of his work on Yelp and he did not disappoint. I called on a Sunday and he returned my call the same day. We scheduled a day for him to come and give us a quote and he arrived right on time. He was extremely responsive throughout the entire process and provided exceptional customer service which I find lacking with many tradesmen. He provides you with samples to look at and since we wanted quartz, he brought several different samples for us to look at. He went and bought it for us, picked it up, and delivered and installed on the same day. The entire process took maybe a week. And his quality of work is exceptional. You will not regret using him. read more

We went with Carlos to install quartz in our kitchen. His pricing was great and the turn around time from ordering to installation was actually faster than we were ready. We had to ask Carlos to delay a week in order to be better prepared for the installation (we were waiting for our sink to be delivered). We could not be happier with the outcome. Carlos was timely and so easy to work with. Definitely recommend! read more
