I purchased over 20, 000, with them, and then needed another counter top. The girl that was helping me said that since i was a few dollars short for free delivery, she would give it to me anyways. when i called back to schedule for delivery they told me i need to pay fifty dollars. i tried to speak to the girl that told me this . when she personally answered the phone she ask if i could please hold so that she can send me to her supervisor to tell me i still need to pay the fifty dollars. This i thought was chicken sh*t for all the money i did spend with them. Never again will i buy from this place. read more

Angie was excellent, so was the other gal (I never asked her name . I had been to another stone yard and preferred the variety here! So may beautiful slabs! We mainly looked at the quartzite and the quartz but they also had dolomite and granite! We also plan to order our sinks here. They only have 2 kitchen and 3 bathroom on display but they have a magazine to show their other options. We are excited with our slab and can't wait to add a pic of the finished product! Thank you guys for a great and easy experience! read more

Fast forward over a decade, as we venture into our new home, our forever home, we wanted to curate our space with the best materials such as those we have found in the past here at Quality Marble & Granite. How refreshing to be able to return to a business that has kept true to their standards of service and quality of products. Our sales representative Monica greeted us right away and her knowledge of stones was impressive. She was patient and answered all of our questions regarding finishes, styles, durability and of course costs. We valued her opinion on our questions regarding trends vs timeless choices. We are definitely timeless not trendy, so natural, unique stone over the easily acquired stuff is within their wheelhouse and what we found on site. There are so many beautiful granites and Quartz stones on this lot but I also requesed pricing for Petrified Wood countertops. They delivered. A five star Solid as Rock all around experience from Quality Marble & Granite. Highly recommend. read more

Having your kitchen redone is a stressful project... especially for some of us common folk who don't have the luxury of switching out the kitchen when trends and times change. My installer recommended this place and I'm glad I went to check it out. I pulled up to the warehouse and entered the by building. Was greeted a soon as I entered. The ladies in the front all seemed to be polite and even offered me a water bottle. Once a representative took me to the showroom I explained what it was that I was looking for. She took me to some slabs and it wasn't before long that I found what I want wanted. I must express my shock to have found it locally when I had driven around every where for the last month. My advice is that you should definitely NOT settle. Try this place out. Hoping you have the same luck I had! read more

Evan the owner and Ednita the customer service/sales person are the two people I have worked with at Quality Marble and Granite. I have used them and purchased product on six or seven occasions. They have always been extremely patient and helpful at a level that is unfortunately less common these days. They have a good choice of product which allowed us and my clients to have peace of mind that our choices were the right ones. I wouldn't recommend taking a chance going elsewhere, as I know your experience here will be a great one. Randy read more

Met with Monica. She showed us exactly what I came in for, plus 3 more options. Slab, prefab and man made options. She gave us a quote for all of them plus referrals for 3 contractors. She also sent us home with a sample of one of the man made options. Great help, thank you! read more

I saw some picture from this place with a reviewer's counters that I had to have.

I had a great experience and education on slabs for countertops and the various types of stone found in granite. rare minerals, such as garnet add color to the granite and the various formations are very appealing. Because quartz has a warrantee because it is manufactured, granite and other natural stones don't have such a warrantee, and have a higher maintenance to ensure the stone is sealed against moisture and stains. This location had a multitude of slabs and reasonably priced for sale to contractors and installers. I would recommend shopping around and become educated on the various options, if you're in the market for a new countertop or possibly flooring. read more

Quality Marble & Granite has got to be the best place in Southern CA to shop for higher end countertop surfaces. Once you visit them you will never want to go anywhere else when you are looking to purchase either granite or marble. They have an astonishingly fantastic selection of surfaces which makes them a significant standout from any of their competition within a two hundred mile radius. What makes them even more exceptional is their unbelievably friendly and knowledgeable staff. Both Angie and Monica were incredibly patient with me as I looked through a wide variety of slabs. I made multiple visits and every time they treated me like a VIP. I had lots of questions and Monica always went out of her way to make sure they were all answered. They really make you feel at home, they make you feel important and it's obvious they enjoy what they do in helping people pick out the perfect counter surface. You will simply not get better customer service or a larger selection of surfaces. Quality Marble & Granite is an absolute hidden gem and the best of the best. read more

While on vacation, my upstairs restroom had some water malfunction which caused a disastrous flood throughout my home. After searching many vendors that sell countertops/kitchen and flooring, the remodeling company was not able to locate any materials that wasn't a "cookie cutter" type of print or stone. I stumbled onto Quality Marbel and Granite and was captivated by the slabs that were on display right outside the office. I spoke briefly with Evan, whom has been the most knowledgeable and patient person I've spoken with regarding countertops, and he was able to help me narrow down what I needed considering my wants and application. With the Help of Evan and Ednita Bonilla, I found exactly what I was looking. I have yet to get these installed but my wife and I are very excited to see the finished product will look like once it's installed. I highly recommend visiting this place if you're on the market for some remodeling. The broad selection and various materials along with great customer service will make this process easy and painless for you. Lastly, the associated costs are reasonable and affordable...... it's a pretty simple decision for me as to where I will be shopping for my kids restrooms countertop next month. I will post pictures once the installation is complete. Thank you very much for your help . read more

Yesterday I had my appointment to pick out slabs for my bathroom remodel. Laura assisted us and she was AWESOME! I had many questions about the different tyspes of stone and marble and she helped me decide what would be best for our family. She was patient as I went back a forth between some of my favorites. When I liked something she would ask "what do you like about it" so she could better assist in finding the perfect slabs. I was stuck on a slab similar to granite, but really wanted to find slabs that were quartzite. Well I listened to Laura's expertise and she found me the most beautiful quartizite slabs that checked all of my boxes!! This stone is so beautiful and is going to be the focal point of my bedroom and bathroom! My family and I are so excited with the service and quality of product here! We look forward to working with the QMG family again when it is time for a kitchen remodel. We are happy customers for life and will be referring our friends and family. read more

Can't say enough good about this company! They have gorgeous stone counter product that you don't see elsewhere and their prefab slabs are the best deal going.

My husband and I went in twice to choose pre fabs for our new kitchen. The first time we took the time to walk around their yard to try to decide what material we wanted. We found dolomite pieces we really liked and decided we would look at back splashes before making our final decision. The second time we went in, Angie helped us, she helped us decide and choose what exact pieces we wanted. She also showed us pictures of another kitchen that was done with the same dolomite we chose, which was really exciting to see. We can't wait to see our new countertops in our new kitchen! read more

We had been looking for granite, to replace a worn out tile countertop, for months. We had just about given up hope in finding something unique yet functional...until we went to Quality Marble and Granite. They have a great selection of stone and the best part is that you can go into the yard and see the slabs! Seeing full slabs is so important when choosing granite (not just a small sample) because you can see the entire slab and get a better idea if composition/appearance works for your needs. Also, I want to thank the staff at Quality Marble and Granite. Everyone was very helpful. The guys in the yard moved many slabs for us so we could pick just the ones we wanted. I want to thank Ruby Acosta. She was awesome, patient and she had a good understanding of the stone that guided us in our decisions. Thank you Quality Marble and Granite read more

Very poor material, it is kept outside under all types of weather. The slabs and materials kept outside are deteriorating and falling apart.

My wife and I visited our fair share of stone and granite yards all over Southern California. It wasn't until we found Quality Marble & Granite that we found the perfect slabs we were envisioning for our dream master bathroom at an affordable price. In addition to an amazing variety of options we saw at their yard in Ontario (especially natural stone) the professional staff working at QMG were knowledgeable about their products and extremely patient with our numerous questions.  I wanted to write this review to share our amazing experience we had with this company and share photos from the beginning to the end of this journey for us. We both highly recommend!!! read more

Great customer service and awesome selection. They follow CDC guidelines with Covid-19. Appointments will ensure you get 100% attention with no other people around you. The receptionist Ednita was super helpful on the phone and inviting..looked up materials and scheduled an appointment. Rebeca Hernandez took us on a tour and had slabs pulled quickly. She offered valuable feedback and it was very apparent she had good knowledge of the materials which was super helpful. Visited several Quartz wharehouses recently. This was definitely one of the best show room, selection and customer service. Dont let the name fool you! It should be quality Marble, Granite and Quartz..... they also provided samples of my top 3 favorites. read more

I wish I could give Quality Marble 10 stars but it looks like 5 is the best here on Yelp! After helping my folks last year with their kitchen reno and having just finished my own kitchen reno this year I am a little familiar with the various granite/quartz vendors out there. Having personally visited many stone yards in LA, SB and OC I am confident in sharing with my fellow Yelpers that Quality Marble and Granite is the place to go!!! I was referred to Quality by my cabinet contractor and drove up to their Yard in Ontario. When you arrive to their offices you are immediately greeted by their staff. They ask you if you are looking for granite vs quartz vs marble or anything else and then ask if you want a slab or prefabricated materials. From there someone takes you to that part of the yard and shows you the selection. If you are unsure as far as color or design just bring your cabinet, floor, or paint samples and they are more than happy to share their professional opinion. We worked with Larry who was a pleasure to do business with. He worked closely with our cabinet vendor making sure we selected the right size and he gave us the pros and cons of granite vs quartz and also helped us with design decisions given the colors of our new kitchen. At first we were opting for a granite slab but we needed a humongous piece so Larry took us to the pieces that would work. I didn't think I would like them but when he held our floor and cabinet sample to the slab it looked pretty darn good. In the end we decides to go with quartz slabs because well...I always wanted them and their prices were reasonable. We chose the Estancia quartz and loovvve it!!! Thanks to Larry and Quality Marble and Granite for their superior customer service, attention to detail, and quality product. read more
