Constraction reviews in Sunnyvale, California

Jonathan took care of a marble repair I needed to have done. Small job, but the work he did was great, and exactly what we were after. Good communication throughout the whole process. Thanks much Prostone!

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 went above and beyond to take care of a kitchen counter from a kitchen remodel that went bad. I was very stressed out from an awful contractor and Jonathan helped and took care of it. I would recommend this company to anyone looking to remove stains and seal their natural stone counters. Very professional and friendly and did an awesome job.

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.

Great Service always on time and always do a great job, so appreciate Maria and the team.

On time and good crew. Rugs came out very well!

Jonathan and Anthony from the start over the phone were very professional, they were on time for the appointment, and their services were delivered as promised.
Anthony and his amazing helpers cleaned my travertine kitchen floor and then after a week or so re-grouted some missing areas.
I highly recommend Prostone Services.

If you're looking for a fantastic grout/tile repair company Prostone is definitely the company, you want to contact. The owners and employees are professional, knowledgeable and showed up on time to do the work. Thank you, Jonathon and Will for doing an excellent job!

Prostone Services cleaned the grout in my bathrooms and also cleaned a 9 x 12 area rug. They are professional, kind and their work is outstanding. I highly recommend! Thanks Prostone!

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!

We had a great experience with Prostone Services. They were very helpful and informative. My Granite looks great after being cleaned and sealed. We highly recommend them!

Prostone did an amazing job getting rid of a stain on my rug. Highly recommend their services. Thank you!

I've used Prostone Services dozens of times over the years at both home and for a medical office complex I own. I couldn't be more pleased with the level of service they provide and their use of the latest products and technologies to ensure the best possible outcome every single time.

They did some tile sealing, grout clean up, new silicon bead on base of shower glass. We use them exclusively. If you don't believe me, call the shower glass company who exclusively recommends them to do maintenance and repair

As the owner of a tile and stone installation company I would highly recommend Prostone. Their always punctual, professional and provide excellent service. When we remodeled our kitchen and installed marble countertop's we hired Prostone to apply More Anti-Etch and have been extremely pleased with the results. The product offers us the piece of mind to confidently use the countertops without the fear or etching.

Prostone team did an excellent job cleaning our hardwood floors and area rugs. Arrived on time, work went faster than anticipated and they helped move furniture back in place without prompting.

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!

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 arrived on time to both review the project and clean the kitchen and three bathrooms including marble floors and shower enclosures. Extra care was taken to protect walls and floors from cleaning solutions. The result of the cleaning was impressive in the bathrooms, but most noticeable on the kitchen floor which was returned to the original light beige color. I highly recommend ProStone for cleaning and minor repair.

Prostone continues to do an excellent job cleaning stains from my wall to wall carpeting. Maria, Jonathan, and Rodrigo are a pleasure to work with and I can count on them to do a very thorough and professional job.

Prostone completely revitalized our carpets! We were ready to purchase new carpeting, but after this thorough, efficient and effective cleaning, we are thrilled. Our home is beautiful again. Thank you!
