Master Garage Corporation, based in Southborough, MA, coats and resurfaces concrete garage and basement floors. Its Massachusetts HIC license 182666 is active on the state registry. It holds 4.8 stars from 34 ratings on HomeAdvisor. In a 2016 review, Tom came out after hours with a quote for grinding and coating the basement floor of an 1864 house; Phil coated the floor, filled the holes and cracks, and came back the same week to apply a polyurethane top coat without extra charge after the primer coat turned out a bit patchy. In another 2016 review, the company cleaned an old concrete garage floor and resurfaced it with a primer and a polymer coating. A 2016 review called an epoxy floor on garage and basement floors "a great alternative to removing the old tile floor and replacing with new." In a 2017 review, the customer was pleased with the owner's help choosing between polyurethane and epoxy finishes and with the repairs made to major cracks in a basement floor before the finish was applied. A 2018 review described Tom sealing a warehouse floor, scheduled right before the holidays, and called his price fair. A 2017 review gave 3 stars to a Hybrid Polymer concrete floor finish, saying the end product was "not as good as expected" and the work was "bit rushed at the end." In a 2016 review, the customer was waiting for a call to schedule a repair after bubbles appeared in a concrete floor.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Master Garage Corporation. Use it to sanity-check bids, then get the real number in writing.
Estimated range
$6,000 – $9,600

Tom and his crew were able to work with our company and get us a super fast turnaround to seal our warehouse space. Very happy with the results, and with his team's overall professionalism.
Great
Tom was prompt in answering my query about sealing a warehouse floor. He managed to schedule the job when it was convenient for us (right before the holidays). His price was fair and his work was above par. Highly recommend them for your next job.
They are very peroficenal completed the project on time .Excellent customer service . I am happy the work they done.
The owner of Master Garage was very prompt in contacting me about the job, coming out for the estimate, and following through on doing the job. I was very pleased with the assistance I received on which option was best for what I was trying to accomplish (polyurthane vs epoxy finish), but wish that there had been some color samples to look at to help make a final decision. Overall, I am very satisfied with the process and the job. I chose polyurthane to finish a basement floor and was especially pleased with the repairs made to major cracks present in the floor before the finish was applied. I was a bit surprised that the owner never followed up after the job was done to see for himself how it turned out, but maybe he only does that if the customer calls about any issues or complaints.
