GMI Asphalt Plant

GMI Asphalt is a New Hampshire paving, grading and excavation contractor that also makes its own asphalt: the company says it bought the former Hard Drives plant at 33 Punch Brook Rd in Franklin, NH, and runs its paving division from Belmont. It describes itself as standing behind its obligations since 1977, names Warren Colby as owner and general manager, and says GMI and CLD Paving combined forces, citing 55+ years of paving experience between them. The accounts that actually describe paving work are good ones. A 2025 customer praised the measuring and estimating, said an employee named Taylor stayed with them through the whole process and kept them updated on schedule, and noted the new pavement matched asphalt the company laid for them almost fifteen years earlier that is still in good shape. A 2023 r/newhampshire commenter said GMI paved their Moultonborough driveway and they could not be more satisfied, and a 2024 reviewer working in the trade called its asphalt some of the best they had used. The negative side of the record is a different subject entirely. The one-star reviews on file are about driving: a 2025 reviewer described being cut off on a 50 mph road near Meredith, two more in 2025 called the drivers aggressive and unprofessional, and a 2023 reviewer called the operation unsafe. None of them describe a paving job. So the questions worth asking are about site and road conduct rather than workmanship — who supervises the trucking on your job, and who to call if there is a problem with a driver — alongside the ordinary ones about schedule and warranty. The company publishes a materials lien waiver and a workers' compensation guarantee, and says its employees are OSHA certified; ask to see current certificates rather than taking the page for it. New Hampshire does not register paving or home-improvement contractors, so there is no state licence to check for this trade, and none appears in this record.
