Onyx provided us with 5 beautiful counter tops and installed them perfectly. The staff was very kind & professional. The tops came in cut just the way we planned. The installers had to move our very large & heavy tops into our home on two levels. They needed an extra man to help and Onyx sent him out immediately so our job could be completed in one day. We were very pleaaed with their service, their product and their installers. We would definately use them again. Less

Onyx is the best granite and countertop company in the metro west area. They are professional and cooperative. I've used them many times over the past ten years. Highly recommended! Less

This is my first time writing a bad review. The company claims that they are professional and have more than 20 years of experience. The granite installation that they performed in my kitchen was awful. They did not level the granite and left big gaps between the granite and kitchen cabinets. The gaps are so big that I can see through to the other side of my kitchen. The granite appears to have little support and shakes as you walk. The company claims that this happened because my cabinets are old. The first time I came to their office I brought pictures of my kitchen and the cabinets. Nobody asked me the age of my cabinets, nor brought that up as a concern. After we decided to go with the company one of their employees came to perform the measurements. He spent an hour measuring and inspecting every inch including under and over the cabinets. He took many pictures and did not mention that there was anything wrong with the cabinets. On the scheduled installation date three installers arrived. They took off my old countertop and did not raise any concern about the cabinets. Had they raised a concern I would have hired a carpenter to resolve any issues. The company states in their terms and conditions that they only install granite and do not provide carpentry services, however they can provide recommendations. The installers were clearly in a hurry to install the granite countertop, they did ask and receive my permission to cut a little on one side of the cabinets to ensure a proper level. Afterwards they said that they ended up cutting a lot and on multiple sides but were unable to achieve a proper level and left. In the evening, I received a phone call from one of the installers that the owner Jose gave him permission to come to my house and attempt to resolve the gaps, however he told me this would cost extra. I was skeptical because I had signed all the papers with the company, and not with the installer who appeared to be a subcontractor. Next day I went to the office and asked the owner Poliana how we could fix the problem with the installation. She gave me several options but told me that Jose would come by and look at the installation. A couple of days later Jose came and instead of looking at the installation and offering solutions to resolve the poor levelling and gaps he let me know he was there for the remaining balance. I convinced him to look at the installation and for every fix that was suggested he told me it would cost extra. Jose was completely unhelpful in this situation. He was unwilling to work with me to find a resolution for their poor installation and was only trying to extract more money to resolve their mess of an install. He does not care about the satisfaction of his clients. The company took no responsibility for their poor work. Less

Onyx Marble and Granite fabricated custom granite pieces for my two bathroom renovations. They were very helpful in directing me to products that were appropriate for my applications and within my budget. Communication and customer service were terrific and I wouldn't hesitate to do business with them again. Thank you! Less

We had a great experience, we came in for a countertop for a rental apartment and the staff pointed us to several options in our budget. The selection of stones is amazing and the measurements and installation appointments were easy to make and technicians were on time. Less

Onyx has very good technicians. They installed quartz countertops in very difficult conditions. They stand 100% behind their work. Will use them again when I do next phase of home improvements. Less

We used them to replace two separate vanity tops in our bathrooms over the past year. Their prices were very fair and the install went smooth with no issues. Would recommend them to anyone! Less

It was a great experience working with Priscilla, from product selection to delivery arrangement. Onyx also have a huge selection of countertop for you to choose from. Overall highly recommended. Less

All my granite countertops were installed throughout the years by this company. The latest was on my deck. I explained what I wanted and when they came to install it, I didn’t think it would fit. Well, they did whatever magic they do, and it fit like a glove! Love it! Thank you Onyx Marble and Granite!! Less

Highly recommend Onyx Marble & Granite. Our new kitchen countertops + island came out amazing! We also added a built-in bar and fireplace with small pieces of black granite that also look fantastic. Communication was great and prices were very fair. Less

They did the counter for an outdoor kitchen. They gave me the best price. Their service was excellent and prompt. They did a superb job. I am very happy with the results. Less

I love my new counters! That’s my favorite part of my remodeled kitchen! I went with Quartz, but they have so many options! The guys that came out and measured and installed were very accurate!I had to have a seam on my “L” shaped counter, which was put in the perfect spot! My only complaint would be is where the seam was put , I have a “lazy Susan” cabinet below and the glue from the seam dripped down and dried like icicles and was very sharp. I did not complain, my contractor just filed the aftermath glue drippings smooth. Overall very good company to work with.I recommend. Less

My experience was stress free! Customer service was outstanding helped me pick the product I needed. Very happy with installation and timeframe of project. Highly recommend. Less

Onyx gives all their customers the VIP treatment regardless of their budget. Great customer service. I did my kitchen counters and recently replaced my vanity to and a custom shower ledge Less

We had a wonderful experience with Onxy Marble & Granite in Framingham. Mara in the office was very knowledgeable. She remembers all the stone’s names by heart. She helped us picked 3 different quartz for the kitchen counter top, the vanity top and fireplace hearth. The installer Alex was very experienced too. Some of the works was pretty challenge but he handled well. We are very pleased with the quartz we picked and the work they had done. Less

All the people at Onyx, from the receptionist to the installers, are 100% professional. And they are kind and courteous people. I had never done a contacting project before. They gave me helpful advice and were patient with my questions and misunderstandings throughout the process. I will definitely hire them again and would recommend them highly to others. Less

I had an exceptional experience with Onyx. Priscilla was very flexible, responsive and communicative and the install team were so friendly and professional and worked incredibly cleanly and efficiently. I would definitely use them again in the future. Less

Had a great experience - we paid half the price here, getting the same stone we would have gotten elsewhere (only difference being the price). Easy to communicate, even when we had to reschedule because of our own construction delay. Workers were on-time, and their install looks great. Less

Excellent service: professional, curious, responsive. They noticed defects on the delivered countertop, took it back, and replaced it with a new one. I was stunned. Less

Onyx Marble and Granite provided exceptional service. They are small company that fabricated and installed slate counters. I couldn’t find anyone else who had the experience to do that in the Greater Boston area and Onyx were excellent. I highly recommend them! Less

We used Onyx , Granite and Marble 9 mos ago for our quartz countertop for a double bathroom vanity. It was a great experience. From the salesperson, to the people who cut and measure the quartz , to the meticulous installer, everyone did a great job. If you don't need whole slabs, they have a variety of slabs that you can choose to purchase only what you need. I would definitely recommend using this company. Less

We love working with Onyx because of Jennifer Pimenta. She is so knowledgeable about stone types and always takes care of our clients. She patiently goes through all the different colors and options.
