Renovating in Brunswick, ME
Brunswick sits at the northern edge of the Portland labor market, and pricing reflects it — close to the Maine average rather than the Portland premium. Contractors here often serve the Bath and Topsham corridor as well, so travel time is priced into smaller jobs.

Maine regional index with a 0.99× Brunswick metro factor, 10% contingency included. Budgeting estimates, not quotes.
Estimated range — based on BLS OEWS national average wages and BLS PPI material indexes applied to Our Haus baseline unit costs, as of June 2026. Estimates are shown as a range and help set expectations. They are not a quote, a verified price, or an appraisal of what a contractor will charge.
Housing stock and what it means for cost
Federal and Greek Revival homes on and near Federal Street and Park Row, mill-era housing near the Androscoggin, mid-century neighborhoods around the former naval air station, and newer building at Brunswick Landing. The historic stock is genuinely old — expect plaster, original framing, and lead paint.
Neighborhoods: Federal Street Historic District, Brunswick Landing, Maine Street, Pleasant Hill, Mere Point.
Permits and contract rules
Authority: Town of Brunswick Codes Enforcement Department
Building permit plus zoning review; trades pull electrical and plumbing separately. Exterior work in the Federal Street and Park Row historic districts goes through additional review. Shoreland zoning applies along the Androscoggin and out toward Mere Point and Simpsons Point.
Maine requires a written contract for home-construction or repair work over $3,000. The contract must include the contractor's name and address, the work and materials, the total price, a payment schedule, start and completion dates, a warranty statement, and notice of the state's contractor-dispute mediation program. Maine does not license general contractors, so verify insurance directly with the carrier.
Season and scheduling
April through November for exterior work, with the spring queue filling early. Winters here are slightly harder than on the immediate coast, so weather protection for open framing is a real budget line.
