In an October 2022 Google review, a customer who gets rock and gravel from Alvin J Coleman & Son for driveway maintenance called the company friendly and timely: "They drop where I need to use it." A February 2022 customer wrote "Very nice people very very helpful!" and a December 2021 customer "Professional contracting team." Google shows 4.6 stars from 30 ratings. The company describes itself on its website as family owned and operated, specializing in heavy earthwork construction in both the private and public sector; it says it is based in Conway and travels throughout New Hampshire and into Maine and Vermont on a regular basis, and that it has been in business 86 years. An article on the construction trade site acppubs.com describes the company using excavators to clear blasted ledge, and a 2020 r/newhampshire commenter named Alvin J Coleman among contractors used by the state.
“Many of contractors used by the state are NH like continental or Alvin j coleman”
“worked closely with project's general contractor, Alvin J. Coleman & Son Inc.”
“Alvin J. Coleman & Son Inc. employs Caterpillar and Komatsu excavators to clear away blasted ledge during the widening of F.E. Everett Turnpike in New Hampshire.”
