Literally worst service! Walked through the whole store, walked past 6 employees who where all staring at computer screens and not one person said hello or even offered to help!! Walked in and walked out like a ghost. How does this place make money if they just allowed a possible customer walk away. We will not be customers of this place!!

After some frustration with other vendors I found CornerStone on Yelp. So glad I did. The work was flawless. The kept in good communication with me and I am loving my new countertop, sink and backsplash. Huy is amazing.

A true Bait n Switch where they have you drive 40 miles just to find out there is no Quartz or Quartzite for $1,500 per slab, not even close...

Dan Paggi is the best! He is so knowledgeable, extremely helpful, and patiently answers all of your questions.We are very happy with the experience at Cornerstone. Remodeling project is very stressful and I have to say, Dan has made life easy for me.We will definitely be going back to Cornerstone for any future remodeling needs and will be referring friends and family as well.

We got several orders for our kitchen projects from this store. Every time they deliver above and beyond in terms of quality, price and understanding our needs. Yes I want this shade & color in this size & shape. I don’t compromise on what I want when we spend on big projects. The team did a great job serving our needs on all stages: design, procurement, delivery and OMG custom installation by 3! crew members!

Hassle free one stop with friendly service and lots of resources and advises. If you need to get your kitchen or bath redone or want a new design, come here and you will likely get all your needs addressed in one place. Owner Benson has good taste and great personality. I have done my past few projects here and will be coming here again for the next one.

Were DIY without professional designer. The staff at Cornerstone were very helpful in helping me pick tile, countertop, faucets, and even accommodating cupboards I bought elsewhere. Albert was very helpful. I am doing another project now and intend to use them for all they can offer. I do recommend. They can offer good prices and a wide selection of materials.

Cornerstone helped me with a full kitchen and 2 bathroom remodel. They walked us through the entire process, with good recommendations in our budget, and were endlessly patient and accommodating. Ill never go anywhere else.

Great selection and showroom. Customer service by Claudia was excellent. The came in performed demo, installed new countertops in the kitchen and the bathroom with under mount sinks. You couldnt even tell that they were there spotless!Thanks I know where I need to go the next time I need this type of work!

Everyone at Cornerstone has been very helpful. I mostly interated with Cat and she was great: very responsive, accurate and truthful to her statements and promises. They did a great job with the stone fabrication even a stone purchased elsewhere (they didnt have what we wanted). I will continue working with them for all my remodeling needs they can cover.

Wonderful one stop home design center. This place is for the more experienced remodel(er). Expert help (be sure to ask) and very knowledgeable. If your looking for the one of a kind items, Cornerstone is the right chose.

CornerStone Home Design has done work for me in a timely, professional manner. The workers are skilled, polite and considerate. They are clear about when work is to be done. I was in a very difficult situation a couple of times and they came to my rescue.

We had our kitchen remodeled with Mr. Unger from July-August 2019. The process was smooth and Dmitriy helps you along the way providing you with next steps to complete the project. His employees: Marcus, Nikolas and Anatoli were all amazing. Marcus did a wonderful job on demolition and replacing our electrical system. Nikolas and Anatoli then installed everything for our new kitchen. These guys are masters at what they do and they will complete the tasks requested of them expertly. I have no reservations about recommending Mr. Unger and his construction company to anyone looking to remodel a kitchen. I am very satisfied with their work.We had some other projects going on at the same time like popcorn ceiling removal and patio door replacement while Mr. Unger and his crew were remodeling and they were extremely accommodating and worked around these other projects. Everything worked out and our kitchen looks amazing!

Cornerstone was a great resource for our bathroom remodel. We got tiles, countertop, fixtures and bath vanity from them. They even carried items that are not listed on a manufacturer’s (Ronbow’s) website on account of their service and quality. Albert and Gabe were very helpful in picking out stuff and making suggestions. Would highly recommend them for any remodel.

A great team to work with. We have been using Cornerstone for years and plans are very well done, accurate, and pass code. I would recommend for any job.

Cornerstone is a one stop shop for plumbing supplies. They have a great selection of tiles, some granite, and some pre-fab granite counter tops. If you the pre-fab granite it can save you a bundle.Gabe is usually buy, but he is extremely knowledgeable and is an immeasurable help with selecting bathroom and kitchen fixtures. They have a large selection on display. Gabe has a sense of style and knows what goes with what.I found I could get a better price on some items elsewhere, but prefer getting everything from one vendor. This makes returns and pickup much simpler. I purchased a whirlpool style tub at a great discount from another supplier and had serious problems getting it working. I should have ordered the tub through cornerstone as well!Call Gabe at Cornerstone, youll be glad you did.

CornerStone Home Design really came through for me! I would highly recommend them. Got my countertop, sink, and kitchen faucet here. Great selection and service!

I love how this is a one stop place to shop from counters, tiles, cabinets, plumbing, glass enclosures!!

Large selection of everything, but pretty pricey compared to all the other stores in the area. It’s just a pity, the staff were rather helpful in showing us their catalog and showroom...

My wife and I visited the store for the first time. The purpose was granite as we following on the response to an email inquiry from the Google search... Our expectations for the visit were way exceeded on many aspects: variety of the produtcs (cabinets and appliances in addition to the stone); riendly service; proficiency of the consultants. This place is very worthy to visit!Lev & Olga

Just the right amount of help in the warehouse when it comes to browsing and selecting our final bathroom countertop choice. There is a wide selection and enough people around to guide us in the right direction.There were some issues and misunderstandings, but everything was taken care of by the staff at Cornerstone.

Benson is the best....informed, polite, attentive.....and his staff is also great..Check out their fab products.....worth the drive.

We worked with Liz at Cornerstone for our kitchen remodel and are very happy with the results. Liz was very attentive and patient through the whole process.We ended up choosing Columbia Cabinets with quartz countertops. Our contractor installed the cabinets but Cornerstone installed the countertops. We had a small issue during installation of the countertops, but Benson (the owner) quickly stepped in to make sure everything was fixed to our satisfaction.The service has been remarkable and the quotes were extremely reasonable. I wouldnt waste time looking at too many other places besides CornerStone for your kitchen remodel.

Great costumer service and the price are the best in the Bay Area

Kat and benton are great. Love this place!!!!

Great countertops and customer service.

Excellent Service!
