Additions, structural repair and trim carpentry

More room, a house that's sound again, and the finish work that makes it look like it was always there. Over two decades of working on houses in Greater Boston.

Additions

If you want to add a room or a whole wing, we'll build it. Often you can gain the space with less:

  • Finish the attic or basement for a guest room, playroom, hobby room or home theater.
  • Convert a room that no longer fits the way you live, like the kids' old rooms into a gym and a home office.
  • Add a bump-out for a breakfast nook, a bay window or a walk-in closet, on a cantilever or a ground-level foundation.

New rooms we build often: bedrooms, bathrooms, living rooms, sunrooms, garages, mudrooms, dormers, storage rooms and offices.

Structural repair

Boston-area weather is hard on houses, vintage ones especially, and some newer homes have problems from faulty work at the start. We repair foundation walls, floor joists, rafters and window and door headers, and replace support beams in houses that are sinking. To open up a floor plan we replace load-bearing walls with LVL beams. We also fix squeaking floors and level slanted ones.

Trim, molding and carpentry

A simple crown molding, custom door casings or a complete whole-house finishing job. After 20 years renovating in Boston we know the old houses and their out-of-square corners.

What customers say

  • “The guys at AMS were great they gave us several options for our renovation which included replacing an old deck for a new bigger one and adding a new 4 season sunroom… The mantle for the fireplace was custom made for an electric insert we picked.”

    Chris Summerlin
  • “The bathroom came out beautiful and the small addition blended in seamlessly with the homes exterior.”
