Symphony Concrete Coatings

Symphony Concrete Coatings is a Tyngsborough, MA outfit built around a one-day fix for a tired concrete floor — Penntek polyurea and polyaspartic coatings for garages, basements, patios, pool decks and commercial floors across Massachusetts, New Hampshire and Maine. The company says it's owned by Gary Rawding and reports 20 years in business as a Penntek certified installer. The volume here is real: 4.8 stars across 176 Google ratings and 4.9 across 55 on Thumbtack, plus an A+ grade from the Better Business Bureau. The story that repeats across 2026 reviews is a same-day or next-day job done by a named two- or three-person crew — Artie and Ivan, Tim and Joe, Seamus and Connor come up again and again — who show up on time, walk through the process, and leave the space cleaned up. Several customers name the same salespeople, Chris, Dan and Matt among them, walking them through samples and pricing before they commit, and repeat business shows up too: one 2026 reviewer noted it was their second job with the company. The record isn't spotless, and it's worth knowing where the rough edges are. In an April 2026 review, a customer described a noticeable ripple and uneven edges after a garage floor install, and had to get the crew back out a second time to fix it. Further back, a 2024 review described being ghosted after a costly job, a 2022 review said the coating's durability was "grossly overstated" and deteriorated early, and a 2025 review described a no-show for a scheduled quote appointment with no call. A 2025 Reddit poster also pushed back on the product's marketed stain resistance, describing tire marks that left permanent stains. For a one-day garage, basement, patio or pool-deck coating job, the volume and rating here hold up, and the crews people name by name suggest a company that keeps its installers around. Before booking, it's worth asking what happens if the finish doesn't cure flat and getting the quote, timeline and any promises about durability in writing, given the handful of complaints about cure issues, no-shows and unmet expectations mixed into an otherwise heavily positive file.
