Dennis and his guys did such a wonderful job. They told us that they could replace all of our counters in the kitchen and master bathroom in one day and they did it. They showed up on time and stayed late into the evening to compete all the work.
Even more important, a problem surfaced 2 days later with one of the faucets that they replaced and Dennis showed up at 7:30 in the morning with the plumber to fix it. That is great service.

I wanted to take a moment and just express how wonderful my experience has been with Dennys and his team. From the first phone call through the final installation we were completed in less than a week. We spoke with so many other vendors and received quotes but ultimately the price this company gave us was the best. We got to choose granite from 100's of pieces and the workmanship was top of the line. Our counter tops are beautiful-more than we dreamed of! Thank you. We will surely recommend this company.

Thanks very much, from both of us, for helping make our holidays so pleasant. Upgrading our kitchen has been on our “to do” list

for a few years, and the responsiveness and professionalism of Granite Marble Specialist, LLC, enabled us cross it off our list in time

for the holidays. And, from the beginning, it was a genuine pleasure to work with you and your crew for several reasons. First of all, your price quote was the best by a substantial amount. That difference could have raised a question on quality expectations, but, when one of your competitors/fellow contractors gave you a strong endorsement, in terms of your price and your reputation, that issue disappeared. Secondly, our visit to your granite supplier impressed us favorably – the selection and quality of granite product was amazing. Thirdly, your flexibility and willingness to meet our schedule was very important and most welcome. And lastly, your installation crew was highly professional, polite, and very friendly. In short, you and your crew exceeded our expectations in every aspect of the project. Frankly, we could not be more pleased. On a scale of ten, we’d have to give you eleven. Keep up the great work!

I'm writing this note to say how please I am with the service granted my home by Granite & Marble Specialist LLC. After researching companies in the Metro area I decided to up grade our kitchen counter to Granite. The company was very prompt, which is "VERY" important to me gave excellent service and we would refer as well as use again in the future. Thank you very much I love my new face lift on our kitchen

We are very pleased with our experience with Dennys Velasquez, who fabricated and installed our new granite countertops for our kitchen. The price is competitive, and a free sink and faucet is included. The selection of granite colors and edging options is plentiful, and although the selection of sinks and faucets is not huge, it is certainly adequate. 

Dennys met us at the warehouse to help us choose suitable slabs for our needs. Once the final decision was made, Dennys was able to fabricate the countertops and have them installed within a week. 

Dennys and his crew arrived at our home promptly at the promised time and did a great job of installing our new granite countertops. They came out beautifully!

I would definitely recommend Dennys' services and plan on calling him again for future projects. He offers a good value, the selection of granite colors and edgings is ample, and the quality of the fabrication and installation is excellent.

Iman ,

I am a very meticulous person not only with the product I purchase but also the service I receive. I did not know Dennis prior to his work in my kitchen. He was referred to me by someone I know. I must admit Dennis is very professional and went out of his way on numerous occasions to accommodate my needs. Not only did he drive a long way to meet me (Showing me many slabs of granite) on his day off, but he did it on a national holiday. He was very knowledgeable of his work and consulted me while we looked. He gave me a great deal and had professionals come to my house and make my kitchen look beautiful. He continued to stay focused and completed a difficult accomplishment in just one visit. Just to give an example: He was hungry and it was lunch time for everyone to eat. I expected him to take a break and eat lunch but he continued to be so focused at what he was doing that a not so warm meal was not a factor for him. His commitment in making sure I am happy was #1 on his list and he truly demonstrated that.

I am very pleased and impressed with Dennis's work as he followed through on every level completely. He even stayed in touch with me and made sure my kitchen was up to my desire a month later. I am very satisfied with his professionalism not only in his communication but also his work and commitment to me as a client. Last but not least, he provided me with the most competitive price for what I received. As a result, I highly recommend Dennis to anyone who is ready to make a change in their Kitchen, Batch, Home and Life!
