    This is the slab after we ripped out the carpeting and some tiles.
    Aldo M.

    I cannot recommend this business enough. We got bids from several companies and it became quickly clear Gem Concrete was the right choice. They were the only company who had residential pictures on their website, so that added comfort in knowing they know how to balance smaller jobs alongside large, commercial ones. Very responsive. Amy was very kind, patient and on top of comms with us. She sent us clear photos of past work so we could gauge quality, stain and finish. Contract was no nonsense, easy to read and the price was right. Day of the job, Tomasi and Rigo were super efficient, easy to talk to and completed on time. And the floors look GREAT! Check out the before and after. Nice work folx!

    This is just...well, beautiful.  And completely impervious to water, pets, and red wine...!

    Gem Concrete Polishing managed to turn our nasty, 50-year-old condo concrete slab into a floor more beautiful and durable than I ever thought I'd own. And they did it under budget and on time. Absolutely AWESOME customer service, Tomasi and his crew, and Amy in the business office, demonstrated consistent professionalism and responsiveness. Plus the pricing was VERY competitive. HIGHLY RECOMMEND!!

    We had been searching for a company to complete some concrete work for some time. Not knowing all of the concrete terminology we had a hard time finding someone who would complete exactly what we had been looking to have done and not charge us an incredibly high rate! Then we found Gem Concrete Polishing! Not only were they extremely helpful in explaining the unfamiliar terminology and processes to us, they were so kind and amazing to work with! They were able to complete the job extremely fast and I could not have asked for a better company to work with. They helped us to transform our facility and we have had so many compliments on our brand new floor! We are so grateful for Amy and Tomasi! We definitely recommend them!

    I am over the moon with our finished floor - its beautiful and shiny and so easy to take care of. Much improved compared to our dusty concrete. Everyone that we dealt with during the process was professional and respectful of our home. I opted for a high gloss finish which costs more, but I recommend. If you are on the fence between polishing v epoxy, I highly recommend gem polishing. The floor finish is beautiful - I love the natural flecks that appeared in the concrete as a result of the polishing process. I have no hesitation in recommending this company

    Garage floor polished!
    Umut D.

    From start to finish it was great working with GEM. Very quick responses, on time with completing the work and super kind people on site delivering a great quality job. We had them do our garage floor and outcome was just unrealistic. They turned such an ugly surface into a beautiful floor and keep getting compliments from everyone that sees what they achieved. Wishing all the best to this family business. No doubt that they will continue to grow if they keep doing what they are doing!!

    We converted our small detached garage into office space and a music studio. We decided that we wanted the floors to be polished concrete. Our contractor hired Gem Concrete Polishing and we couldn't be happier with the results. They are beautiful and look just as professional as floors we've seen in restaurants and hair salons. We absolutely love the look and Amy and Tomasi were so friendly, informative, professional, and responsive. We have already recommended them to others looking to have polished concrete floors in their living spaces.

    Super friendly owners. Great response time and a very good price compared to others. Not just the price, but their work is above the what was expected. Very careful with everything, super clean, and very meticulous with details and corners. Will definitely use again for other future work. Highly recommended.

    These guys are absolutely fantastic! We have a concrete area on the front of our house in San Francisco that used to have all this ugly wooden structures built on it with some tile work. We had ripped out the wooden stuff, but the tile remained and the concrete looked old with small holes where there were bolts that held everything down. I looked and looked and struggled to find a company that would even handle this job. I found GEM on Yelp, reached out to them, Amy responded in maybe 10 minutes, they came out the following week to take a look, and Tomasi and the team came out the following week and did the job - which looks fantastic. It basically looks like the concrete was poured yesterday. They were fast, professional, and the price was great. My only problem is that I don't have any other projects they could work on! I highly, highly, highly recommend them for any concrete needs.

    Ask the Community - Gem Concrete Polishing

    Do you do epoxy or coatings?

    No we do not.

    Do you polish slate floors?

    No we strictly polish concrete.

    Can you polish to a high sheen without applying a coating to make it shine? Thank you.

    Yes! Thats exactly what we do. We polish the concrete using diamonds on a planetary grinding machine. Then we seal it with a penetrative guard, but this is not a coating and is not what makes it shine.

    Do you do driveways?

    We do not.

Jonathan was an incredible person and super nice - really personable and his wife was also the most responsive person ever - always quick to answer questions and provide the quote/invoice right away as promised. I hired them to finish up flooring since I had some injuries and couldn't finish up the work and their quality and speed was phenomenal. I have an eye for attention to detail and their crew was above and beyond in how they did the flooring, going the extra mile for things that normally would be a quick shortcut for contractors hoping the customer would miss it but they didn't take any shortcuts. They were reasonably priced - not the highest or the lowest quote but Jonathan was what sold us on the work and we're more than happy to have gone with him and have recommended him to other neighbors. There's a reason why they are so backed up with work! They're popular for a good reason. They're finishing up the work today and the guys are respectful, clean up after themselves and super nice to chat with. Definitely would recommend Jonathan and his crew to anyone looking to have the best flooring done the right way. Just like their slogan says!

The first was about ten years ago for another portion of our house, and once again they did an outstanding job. They were helpful in selecting a flooring pattern that matched our previously installed floors, and the estimating and scheduling process was straightforward and easy. The installation crew paid close attention to detail, and you can tell from the work around corners, transitions, and trim that they take pride in their craftsmanship and quality. We also appreciated how transparent they were regarding areas where our subfloor was uneven (which we knew would be a problem going into the job). They assessed the condition, explained the available options, and then corrected the subfloor so the planks could be installed the right way. Having a section of our hallway flat when it's been uneven for years has been a great bonus. It's reassuring to know a company like this exists in Concord. Fleury's is the only place I would use for flooring in the future.

Fast forward to present day and time to replace 30yr old original carpeting upstairs. Because our prior experience with Fleury's went so well, naturally we returned to them for phase 2. I started with Chris at the store to present the project and he made suggestions for makers and brands to best match the Brazilian Cherry we had downstairs. Patrick was up next with onsite inspection, measurements, and bringing over samples. A complementary (and upgraded) product was chosen and install timeline was set. Javier and Kiko were next on the scene and took only 5 days to demo carpet, prep and level subfloor, and install flooring and baseboards in 4 bedrooms and a hallway. Patrick came by a couple times to check on progress and made a great suggestion to add additional underlayment. That - combined with their tried and proven method of gluing and nailing down the floor - made for the most solid-feeling hardware floor installation I've ever encountered. I'm a pretty picky customer, so when I tell you their craftsmanship, attention to detail, and finish skills are top notch - believe it. Prices and labor these days are pretty much standard all around. But if you receive this level of workmanship and flawless results, you sleep better knowing you made the right decision. Can't say enough about my experience with Fleury's. 10/10

However, once installation started, things changed significantly. The crew arrived late every day -- typically 30 minutes to an hour and a half -- without any prior notice. Communication with the contractor during the project was difficult to maintain. The project was quoted as taking 1-3 days but ended up taking 6 days. While some of the delay was due to necessary leveling work, the first day consisted only of carpet removal with less than 4 hours of actual work. The flooring itself looks great. However, the finished work left several issues: gaps along the baseboards, paint damage on the walls, and pink staining in multiple areas. One gap measured nearly 1/4 inch and was only addressed after I raised it myself-- it was not proactively caught or fixed by the crew. Additional smaller gaps remain unresolved. The walls and baseboards were noticeably more damaged after installation than before. The initial impression was positive, which made the overall experience all the more disappointing. Based on my experience, I would not recommend this company.

They even worked with me and the manufacturer to get extra discounts since I would need to redo the kitchen as well to match the latest LVP version. They finished the job (~1900 sqft) in just about 4 days and they even helped move many items including disassembling my master bed, at no additional cost! The team is super respectful, and the attention to detail (while not perfect) far exceeds what I would expect given their competitive price point. I am also really impressed with Mark's responsiveness over text, providing updates and responding to concerns - including after hours! His and his team's level of customer service, again, is really top tier. For example, when his team accidentally broke a couple of ethernet cables, he offered to deduct the cost from the bill right away. And at the end of the job, he encouraged me to compile a punch list of any issues that needed to be addressed in a return visit, which should happen very soon. Despite pretty much all of the work being finished - he has not asked for the 2nd half follow up payment yet - not until they complete the punch list at the followup visit. Really commendable company! I also love the music the install team plays during their work (they are also willing to turn it off if the customer needs it quite). So I was thrilled that they were willing to send me the youtube play list. Happy to recommend this company for your next flooring needs! I may even be trying them out for a bathroom remodeling project soon via their partnered remodeling company. Fingers crossed!
