A Maine Contractor That Knows Maine Homes

Most of the homes we work on were built before 1980. They have balloon framing, knob-and-tube wiring, fieldstone foundations, and insulation practices that made sense at the time but leave today’s homeowners with cold floors, high heating bills, and moisture problems that show up decades later.

Maine’s climate adds pressure that contractors from away simply have not dealt with. Freeze-thaw cycles that stress every joint and seam. Humid summers that condense on cold surfaces and grow mold in crawl spaces and attics. Heating loads that expose every gap in your thermal envelope, every winter, without mercy.

We work across the state because the problems are the same whether you are in Portland, Bangor, or Rangeley — but the homes are different enough that you need a team that has seen them all.

Our assessors and installers are Maine-licensed, Efficiency Maine certified, and BPI-certified building analysts. We do not send a salesperson to your door. We send a technician who can tell you what your home actually needs.

What to Expect When You Call

Local Response, Not a Call Center

When you call (207) 777-6020, you reach our team — not an answering service or a national scheduling platform. We know the towns we work in, the housing stock in those areas, and the contractors and inspectors our customers often work alongside. That local knowledge matters when you are trying to understand what your home actually needs.

One Team for Multiple Services

Mattra handles mold remediation, insulation, air sealing, crawl space encapsulation, roofing, siding, rot repair, water damage repair, and more — all under one license and one crew. You do not have to coordinate five different contractors for a home that has overlapping problems. We assess everything in one visit and can coordinate the work in the right sequence.
