How the Maine figures are worked out
Every range on this page is the national estimate with one adjustment: the labour portion is scaled by what construction actually pays in Maine.
Wages come from the BLS Quarterly Census of Employment and Wages, 2024 annual averages, NAICS 23 (Construction), private ownership. Maine averages $1,381 a week against $1,559 nationally, an index of 0.886. Applied to a labour share of 45%, that gives a multiplier of 0.949.
What this cannot tell you. It is a state average, and the gap between a metro and a rural county inside Maine is often wider than the gap between states. Materials are treated as national, which is close to true for lumber and shingles and less true where freight is long. Permit costs, local code and how busy contractors are that month move real quotes as much as wages do. Treat this as a starting point and get a written quote.
Questions about Maine costs
- Is home improvement more expensive in Maine?
- Construction wages in Maine run -11.4% against the national average of $1,559 a week. Labour is about 45% of a residential project and materials cost much the same everywhere, so that works out to roughly -5.1% on the price of a job. Maine pays more than 13 of the 51 states and the District of Columbia.
- Does the Maine adjustment hit some projects harder than others?
- No. It is a wage adjustment, so it moves every project by the same -5.1%, whether that is a tree removal or an addition. What changes is the dollar amount: ADU moves by about $9,200 while tree removal moves by less than $100. If a contractor tells you one trade is unusually expensive in Maine, that is a local market condition, not something this data can show.
- What is the cheapest home improvement project in Maine?
- Of the 36 projects priced here, tree removal is the least expensive at $600 to $1,000 for a typical job, and ADU is the most at $126,400 to $215,200. Both assume a mid finish level; every calculator lets you change the scope and the finish.
- Are these figures accurate for my city in Maine?
- They are state-level figures and should be read that way. The gap between a metro area and a rural county inside one state is often wider than the gap between two states, and the wage data behind this page does not resolve below the state. Use the range as a starting point for what to expect, then get an on-site quote, which is the only firm number.
