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.
Our Haus isn't a contractor directory. We give you the local cost math, the permit reality, and the paperwork tools — the scope, the proposal comparison, and the vault your records live in.

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.
Common Brunswick neighborhoods where this work comes up: Federal Street Historic District, Brunswick Landing, Maine Street, Pleasant Hill, Mere Point.
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.
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.
Typical duration: 1–2 weeks on site for a typical single-level deck.
Size, material, height, and attachment method. Confirm footing depth for your town.
Building permit with a framing plan; some towns require zoning sign-off on setbacks first.
Dig, pour, and inspect before framing starts.
Ledger or freestanding frame, posts, beams, joists.
Surface, then the inspected safety items: stairs, guards, and handrails.
A deck is the most permit-sensitive outdoor project a homeowner takes on — footings below frost line, ledger attachment to the house, and railings are all inspected, and all three are where cheap bids cut corners. In New England the frost depth alone separates a real bid from a guess.
Full checklist: what should be in a contractor's estimate.
We don't keep a contractor directory, and we won't pretend to. The dependable process is to gather two or three referrals locally, check the Maine registration or license rules above, confirm general liability and workers' compensation directly with each carrier, then compare the written proposals side by side against the ranges on this page.

Run it through the quote range checker. We compare it against the Maine cost index, flag line items that look high, and review the contract against Maine home-improvement rules.
Check my quoteAlmost always, yes, once the deck attaches to the house or sits more than a couple of feet above grade. Footing and final inspections are standard. An unpermitted deck is a real problem at resale and with insurance if someone is hurt on it.
For most New England homeowners, yes on maintenance alone: no staining cycle and better resistance to freeze-thaw. The tradeoffs are heat retention in summer sun and a higher upfront line, plus the framing requirement of tighter joist spacing that should appear in the quote.
