How does Maine compare with the national average for a wood deck addition?

Homeowners in Maine typically recoup about 83% of the project's cost at resale, versus ~83% nationally. Maine is part of the New England Census division, which has the 4th-highest renovation resale returns of the 9 U.S. divisions.

What most affects the actual return in Maine?

Recency and condition. In Roots' model, work under 2 years old counts fully toward resale value, then depreciates toward ~20% after 10 years. A home with a documented maintenance record also typically sells closer to asking. Market conditions in the New England division set the regional baseline.

Where do these numbers come from?

Roots calibrates the national baseline for a wood deck addition against the 2024 Cost vs. Value Report (Zonda), then applies a New England-division adjustment derived from division-level averages in the 2024 Cost vs. Value Report, plus the model's own age and condition factors. Figures are modeled estimates, not appraisals.

Is a wood deck addition worth it in Maine?

Quick answer: It can be. In Maine, a wood deck addition typically returns about 83% of its cost at resale, in line with the ~83% national average. You likely won't recoup the full cost, but Maine is one of the stronger markets for it.

How Maine compares

Maine is part of the New England U.S. Census division, which has the 4th-highest renovation resale returns of the 9 divisions in Roots' valuation model. In practice that means a wood deck addition that returns ~83% of its cost nationally typically returns ~83% for a Maine home.

The same regional adjustment applies across the division (Maine plus CT, MA, NH, RI, VT). Nationwide, the spread for this project runs from ~68% in the West North Central division to ~97% in the Pacific division. See the national breakdown for every region.

The New England market

New England has some of the oldest housing stock in the country, and buyers here are used to paying a premium for homes that have been genuinely kept up. Long heating seasons and freeze-thaw winters punish deferred maintenance, so move-in-ready condition carries real weight at resale.

The outdoor season is short here, so buyers tend to value outdoor amenities more cautiously than in the Sun Belt.

Protect the value you add

Whatever the project returns on paper, condition decides what you actually get: in Roots' model the value of completed work fades as it ages, and a documented maintenance record helps a home sell closer to asking. If you're planning around resale value, start with upkeep. The free maintenance checklist generator builds a seasonal schedule for Maine homes in about a minute.
