Theriault & Sons LLC

Theriault & Sons LLC is a family-run paving and site-work company based at 10 Aglipay Dr in Amherst, New Hampshire. Its website describes residential and commercial work including asphalt paving, patch repair, driveway additions, gravel and stone driveways, sporting courts, culverts, site work and sealcoating. The Better Business Bureau lists the company as accredited with an A+ grade. Customer accounts are split. In a 2023 Google review, a homeowner who had an old driveway replaced highly recommended Dave Theriault and Sons and said the company also handles their snow removal. In 2024, another customer praised Sam for a recycled asphalt driveway and a shed move, saying he found creative solutions when the original plan did not work out. A 2022 reviewer described the crew as friendly and knowledgeable and good at laying out options. Two Google reviewers describe problems after the work. In 2024, a customer said they had spent a year trying to get their driveway fixed, that calls went unreturned and that a promise to make it right was not kept. In 2025, a homeowner said the driveway paved two years earlier was bumpy, that the top layer crumbled into loose patches with normal use even after sealcoating, and that a complaint in the first year got no reply. The BBB profile also shows one brief negative review saying the business did not stand behind its work. On Reddit in September 2026, several commenters in a Nashua-area paving thread recommended the company. One homeowner said Dave came out for an estimate and walked through how asphalt works and how the job would be done, and another said they had seen the company's work and that Sam had helped them out several times.
