Symphony Concrete Coatings

Symphony Concrete Coatings is a Tyngsborough, Massachusetts installer of Penntek polyurea and polyaspartic concrete coatings for garages, basements, pool decks, patios, and commercial floors across Massachusetts, New Hampshire, and Maine. The company is owned by Gary Rawding, says it has 20 years in business, and is a certified Penntek installer. It carries an A+ Better Business Bureau accreditation. The review record is large and mostly strong: 149 reviews from 2021 to 2026 across Google, Thumbtack, and BBB, with a 4.8-star Google average from 176 ratings and 4.9 stars on Thumbtack from 55 ratings. The last six months brought 34 reviews with only 2 negative. Homeowners repeatedly describe crews, including named installers like Tim, Joe, Artie, and Ivan, finishing garage floor jobs in a single day, working carefully around cracked or moisture-affected concrete, and cleaning up thoroughly. Several reviewers specifically praised the sales process for being informative without pressure, and one described the company delaying an installation rather than risk a poor result when moisture readings were too high. Set against that strong record is a recurring pattern worth asking about directly. A 2025 Reddit post in r/GarageFlooring said the coating stained permanently from tire marks despite marketing claims of no residue, and that the company told the poster they were the only one experiencing it. Separately, an undated Better Business Bureau review described the crew accidentally spilling acetone on a driveway during installation, then trying to fix the resulting stain with driveway sealer, which left a visible dark rectangle. A September 2024 review described an unresponsive, unprofessional experience and called the company among the most expensive in the category, and a 2022 review said the material's quality had been oversold and urged getting every promise from the sales rep in writing. More recently, a July 2026 review described a salesperson repeatedly pressing for a same-day signature after being told the homeowner was still collecting quotes, and an April 2026 review described a ripple appearing in a newly installed polyurea floor that required the crew to return. On the other side of that same coin, one reviewer whose floor developed a stain months after installation said the company's follow-up service was outstanding and fixed it, so the company does return to address problems, even if not every account describes that going smoothly. For a garage, basement, or pool-deck floor coating, Symphony has a large, well-documented track record of fast, professional single-day installs. Given the handful of accounts describing sales pressure, disputed staining, and one poorly handled repair, it's worth asking specifically what the warranty covers, getting all pricing and promises in writing, and confirming how the company handles a callback if something needs fixing after the crew leaves.
