Prostone Services

The professionals at ProStone were excellent, from start to finish. They came out to estimate and gave a bid in a timely manner. Their bid for our exterior staircase and lobby restoration came in first and at the best price.
We are very happy with the work they performed. They were professional and competent and timely. You can't ask for better than that.

Jonathan and his team did a fabulous job polishing our hardwood floors and granite counter top. They are very reliable, friendly, honest, and fairly priced.

Jonathan and his team did a great job on our tile and granite projects. They were professional, courteous and had great follow-up. Highly recommended!

Amazing customer service. I had a Quartz (not natural stone, hence much more challenging) counter top that needed fixing because my contractor who installed it (brand new countertop!) messed it up. I was heart broken honestly. As I researched, I came across another yelper that said great things about Prostone, so I reached out to them.

Jonathan Ong, the owner, was great at communicating what's realistc right from the start and was patient with me in educating me on various options for fixing it. After some emails, we set a date for the appt. He showed up with another worker, and they were on time, courteous and worked hard in solving the issue. They brought more than what they needed to be prepared for contingency. Reasonable and very pleasant to work with. My husband was also very impressed. I'm much much happier with my countertop after their repair.

I'd highly recommend reaching out to them if someone is looking for any stone restoration or repair.Amazing customer service.

Jonathan and Calvin sealed my kitchen countertop and filled in a lot of granite pits. They were on time, polite, professional, and really focused on getting the job done. After they left, I noticed some residual swirls that weren't obvious under natural light but showed up under indoor lights, so I emailed Jonathan and he immediately scheduled a time to come fix it. I highly recommend them!
