“Had an amazing experience with everyone at Quality Marble & Granite. Laura had so much patience with our family especially on my last visit when I went to pick our slabs. I wanted to pick 2 similar looking quartzsite for our kitchen and the staff moved around a lot of slabs to look for the perfect 2. Ednita, the exec. Ad. Assistant also was very patient in explaining pricing. Really recommend visiting here. They have great prices. Thank you so much!”


“We had a great experience at this stone yard. Laura was so helpful and patient despite it being super busy that day. They had some great options to choose frome. Our contractor said that their pricing is much more competitive than other companies in the local area. Check them out!”

“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!!!”

“Highly recomend!!! We had the pleasure of meeting and working with the sales manager, Art. He went above and beyond to meet our expectations. He was very patient with us and extremely knowledgeable in helping us make the right decision with picking out our counter top. We took a couple sample pieces of our new floor tile to Quality so we could put it next to the slabs that interested us. Art immediately asked what color our cabinets were and came right out with a sample cabinet door to throw in the mix with our tile and different slabs we looked at. The choices at Quality were amazing and we ended up picking a beautiful quartzite slab. My wife was literally in tears finding her dream countertop for our kitchen remodel. Thank you Art, your help and professionalism was awesome!!!!”

“Gorgeous slabs and found exactly what I was looking for. Art assisted me, answered all my questions, and was super friendly. Art provided top-notch customer service and made me feel like I was the only customer he had, although I know we were not. highly recommended, I'd give more than 5 stars if I could.”

“We made an appointment to select countertops for a renovation project. We were promptly greeted as we walked into the door. Laura came out right away and was ready to help us. She explained the different products that they offered. We went out back and looked a slabs, they have a huge selection. We picked out the perfect piece and we can't wait to have it installed. Highly recommend Quality Marble and Granite!”
