603 Epoxy

603 Epoxy is a family-owned New Hampshire company, run by Chris Simpson, that has built an unusually deep and completely clean review record around one specific job: coating garage and basement concrete floors. Across 116 reviews from 2022 through mid-2026, every one on file is five stars, with 37 of them landing in just the last six months — a business clearly busy and still delivering the same result. The work itself is described consistently across dozens of accounts: crews grinding out cracks and imperfections in old concrete, sealing and texturing floors to cut down on slipping, and finishing most garage jobs in a single day or two. Reviewers who'd put off the project for years — one home built in 1960, another after 26 years in a house — describe being glad they finally did it. Beyond standard garage floors, the crew has handled a basement kitchen floor for a Presbyterian church, ramp transitions between a driveway and garage, and full basement floors turned from bare concrete into finished living space. Communication and scheduling come up almost as often as the finished product: reviewers describe being kept informed of arrival times and the scope of each step, working around weather delays rather than rushing the job, and a same-day response from Chris himself to any question. Several mention an "impressive warranty" on the finished coating as part of why they chose 603 over competitors. There is nothing negative in the record at all — not one complaint about pricing, scheduling, or workmanship across well over 100 reviews and more than three years in business. For a garage or basement floor that needs a durable, attractive epoxy finish, 603 Epoxy's record is about as strong as they come: consistent, detailed, five-star feedback describing a crew that explains the process, works around a homeowner's schedule, and finishes fast without cutting corners.
