JC Concrete Polishing

I highly recommend these folks. My basement apartment has been transformed! Graham was a breeze to work with — expert in his trade, on time, kind.

JC Concrete Polishing just finished our pool house floor and they did an amazing job! The work was complete in one day and we couldn’t be happier. Graham and his team arrived on time, they were professional and courteous (and in budget). We couldn’t be happier! One of the best trades I’ve ever working with.

My company used JC Concrete Polishing to grind and seal the hideous concrete left over from previous businesses in our building, one of which used to be a custom furniture wood shop. We got multiple bids and they came out to be one of the most reasonably priced and worked with us to get the project done in two phases. Graham was always a call away and was patient and flexible with our company and scheduling, as we tried to work out timing with our difficult landlord. The floors turned out WONDERFULLY, worlds better than they were before. I would hire JC Concrete and Graham again in a heartbeat… I wish we had more concrete to work on. :)

JC Concrete Polishing deserve more then a 5 star. After getting multiple quotes through Craigslist and other contractors. No matter where I went, I wanted that piece of mind that it gets done right the 1^st time around. Backed by other reviews, this company is legit. They offer a very resonable qoute, licensed, boned, and are very professional. Graham and his crew are great hard workers and did a fabulous job on my garage flooring. Very detail and miticulous, taking the polish all the way to the edges and corners.
For those who are tight on time and storage. They did my garage from 8am to 3pm. Move everything out in the morning, let them do there thing, and its ready to be moved back the same day. How convienent.

Graham did an outstanding job getting my floors done at my new spot in the tenderloin. They were friendly, upfront and completed the job before expected. Now my floors are looking great! One step closer to opening!

These guys rocked it for me today! Really love my new «man-​cave» garage floors. Graham (owner) is super responsive and knows his stuff. He is a no nonsense guy who gets the job done! His crew showed up on time and completed everything in a day’s work. I was left with a beautiful new floor that really sets off the entire room. I also felt like his pricing was in line and fair. Save your time. Don’t shop around. Just use these guys;)

JC Concrete Polishing did a great job for me! From estimate to completion
they were very professional. They take pride in their work.
When Graham came out for estimate he saw a slab mostly covered by carpet. On the day the job was to begin he saw the whole picture. To say the least — it was rough. When I had the slab poured I planned to cover with tile or carpet. So I was not concerned with the finish. It was pitted and uneven,
They arrived around 8am– like they said they would– and quickly got to work.
Under normal circumstances they would have finished my little 400sq ft job by 5pm. But they were not satisfied with the results yet. They stayed an extra 3 hrs and finished to theirs and our satisfaction!
I have another piece of concrete in desperate need of a new finish.
JC Concrete Polishing will be my first call.

I am very happy with JC Concrete Polishing! Graham was very helpful and prompt, which I really appreciated. We have been doing some remodeling in our place, and it has been a nightmare dealing with our contractors, but I am please do say that Graham and his crew were super easy to work with. We had our loft’s concrete floor polished and it came out beautiful!

Graham and Robert and their crew did a BEAUTIFUL job on our garage. It was so junky with glue remnants and super patchy. The polished floor is so nice. We got the ultra fine smooth finish and it looks like marble. Love it!
They also went out of their way to fit us in for another job where we were under a time crunch even though they were booked solid. They grinded down our slab because the previous contractor had tried to use redguard as a vapor barrier.
They cleaned up great and left no dust!

I highly recommend JC Concrete Polishing. From the very beginning the experience was a great one. Starting with Robert with the initial informational calls and estimate to the actual work with Graham and his crew, the experience was outstanding.
The floor turned out wonderfully and it a piece of art in this room. The entire family (including the pets) loves the floor. There were many questions during the process and each and every member of the JC Concrete Polishing team was open to answering them in great detail. This is the type of customer service you want from a company such as this one.
Thank you JC Concrete Polishing!

JC Concrete Polishing did a great job on our floors. We wanted a surface that was easy to care for and good for someone with allergies, so we decided to go with polished concrete. We had carpet over tile that we removed (boy was that fun).
The crew worked hard and were fast at getting our floors done and we have really appreciated the results. They look nice and are as easy to care for as we had hoped.
There were a couple spots that needed touch-​up after the fact. It did take a bit of time to coordinate to get them to come back for the touch-​up because they were busy, but we did eventually get it worked out and they were able to fill in those couple of spots.

Great experience all the way around with Robert and his crew at JC Concrete Polishing. We are renovating our cottage/​guest house and wanted to look at options to simply replacing carpet. Robert came out for the estimate and walked us through the process and the benefits of polished concrete. He is prompt, knowledgeable and very professional. I believe the crew chief was Thomas — he and his guys were equally as professional. They were also prompt, courteous and very clean.
The floor turned out way beyond our expectations — it is beautiful and truly makes the room. I highly recommend JC Concrete — a great product at a reasonable price.

Fantastic company with high quality workmanship. They did ~1,200 sqft of converted warehouse residential in 2 days flat and came in at budget. They went the extra mile on the finishing and polish to really make the concrete look great and be sure the job was done at the highest quality.
Robert helped me with the initial quoting process and evaluation and was extremely knowledgeable about all thing concrete and straightforward about the process and price.
The team was extremely efficient and great to get along with and I’m very pleased with the end product. Graham had some great pointers on maintenance (which is very minimal) and made sure I was happy with the outcome.

JC did an awesome job. I had a basement with a concrete slab that I was converting into a living space. Went from a funky basement feel to a refined modern studio. I highly recommend their work. They were professional, timely, and high quality. I couldn’t be happier with how the floors look and feel.

These guys have it together. They did two restaurant floors for me in Berkeley. They came in on time and on budget. Graham knows what he is doing when it comes to concrete. I would highly recommend them.

graham and his guys just finished my basement floor and it looks great! they are very easy and pleasant to work with and extremely conscientious about cleanliness. i interviewed a lot of polishing companies and i’m so glad i went with JC!

JC Concrete was fabulous.
I was in charge of a Tenant Improvement for a new office in SF, including about 1,300 sf of polished concrete. We wanted a nice tech look for our engineers. I was on a short time frame and contacted several concrete polishing companies (some do it on the side, but JC focuses on this). Graham was able to fit me into an opening the next week. Pricing was very competitive.
They arrived when agreed and worked to completion. I watched a good part of the process; the workers were great, responsive and respectful. They filled the cracks & seams. We were adding a color (Midnight Black), and so the next day they called to have me look at it before putting the top coats on. I wanted it to be more black, so they did extra work to add more color & chemicals to penetrate the concrete and make it darker. The results were great, and their extra efforts were very appreciated.
We all love the floor. Highly recommended.

My experience with JC Concrete Polishing couldn’t have been better. I highly recommend them!!!
I wanted to «finish» the concrete floors in our garage because I use it as a workspace for my business, and the bare concrete floors were becoming a problem. Our home was built with fiberglass concrete, which means that there are these little «hairs» sticking up from the floor. Because I work with plant material for my business, the bits of flower/​leaf were starting to stain the floor and the hairs were getting all nasty and gross. Not ideal at all!!!
I went to Home Depot and bought an epoxy kit to try to give the floors a finish myself. Long story short, it was a complete disaster, and the floor were worse than when I started (the company that sells the epoxy kit even gave me a full refund).
Graham was the first person I called. He was friendly, gave me an awesome quote and was responsive over the phone. I proceeded to get quotes from five other places and his price could not be beat. Other businesses were quoting me $ 600 more for jobs without all the bells and whistles he was offering. Say what???
I finally booked with Graham and they were able to come 2 business days after we decided to work together. He brought a crew of guys, they worked all day and finished the floor in one day. The results are gorgeous. Our neighbor says it looks like granite and wants Graham to do his floor, too!
It’s really important that I work with business owners that treat their workers well. I chatted with the crew when Graham wasn’t around and asked them if they OT pay. Both said that Graham was a great employer, he pays OT and he even gives bonuses when they work big jobs. This guy must be doing something right. Seriously, it’s so easy to cheat workers in this economy. Graham seems like a really honest guy who likes to do things right.
If I ever need concrete polished again, I will def hire Graham again!!!

Just had the guys come over the other week and polish up my nasty garage floor, and man did they do a good job. Had a great experience with Gram and his team, and they really take there work with detail to the end.
When they showed up at 8:00am (ON TIME) they got right to work sanding the entire floor, to perfection. Since the machine was not able to get into some of the area of my garage, they broke out the sander and did it by hand. 12 hours later the floor was like a mirror and the black stain looked amazing.
If your a car guy who gets his (or her) hands dirty, this floor is great. Not only is it perfect for the environment, but it’s your floor. No plastic crap, of cracked tiles. Plus you can still weld and not worry about any flash getting on it.
So all in all it looks cool, and the work was done to perfection, by perfectionists!
