Diamond Paving

Diamond Paving is a family-run asphalt paving and excavation contractor based at 14 Ledge Rd in Seabrook, New Hampshire, working across the Seacoast and southern part of the state. Homeowners hire them mostly for full driveway replacement and overlays, with grading, drainage and site work folded into the same job. The business says it has been paving since 1986 and is now in its third generation, with an owner-operator on site every day. The Better Business Bureau has had a file on Diamond Paving, Inc. open since 1990, lists the business start as 1986, and has accredited it since November 2006 with an A+ grade. The written record is unusually consistent for a paving company. Across 27 reviews from 2023 to 2026, customers name the same people — Jeff and his son Ryan — and describe concrete work: re-grading a driveway to kill a standing puddle, adding a drainage trench, rebuilding a culvert under a long drive, spreading loam and cleaning the road afterwards. Several are repeat customers over multiple years, and one 2023 reviewer said the crew came back after a 2019 job. Pricing comes up often and favourably: reviewers describe a written, itemised quote that did not move, and one 2025 review says the price options and the three-inch coat were spelled out up front. Two New Hampshire redditors named the company in a 2026 southern-NH paving thread, one calling it responsive and professional. The one negative on file is not about the work at all: a 2023 one-star review says only that a truck almost ran the writer off the road. There is nothing in the record about a job that went wrong. New Hampshire does not register paving contractors, so there is no state licence to check for this trade; the business describes itself as bonded and licensed, and that is its own claim rather than a verified credential.
