AMP Builders works on the structure of a house, not the trim: its building permits cover dormers, additions, siding and window work, plus bathroom alterations, on jobs in Cohasset, Hingham and Norwell valued between $21,000 and $246,000. The company is based on Chief Justice Cushing Highway in Cohasset and is owned by Steven Aronson. Its Massachusetts home improvement contractor registration, #202389, is active. Seven projects are shown on its BuildZoom profile, and the business came up in a January 2026 thread on the r/SouthShore subreddit. For a dormer, an addition or a siding job on the South Shore, this is a sensible outfit to get a number from. Ask to see a recent Cohasset or Hingham job of a size close to yours, put the schedule and the payment milestones in the contract, and confirm the insurance covers the scope you have in mind.
