New siding on a home in Cumberland County, Maine

Siding, Roofing, Windows & Decks in Brunswick, Maine

Brunswick sits at the north end of Casco Bay where the Androscoggin River drops over its falls, and its houses cover more than two centuries of building. Ship captains' homes along Middle Bay, Federal and Greek Revival houses around Bowdoin College, in-town streets near the old brick mills, 1980s subdivisions and homes built since 2000 all sit inside one town line. This page covers what that mix means for siding, windows, roofing and decks, and how the town's permit and village review process works.

Brunswick homes and what they need

Census estimates put Brunswick at roughly 9,500 housing units with a median year built of about 1982, so the typical house here is younger than in Portland but the range is wide. Close to one in five units dates from before 1940 and about 31 percent from before 1960, including the houses of the downtown and the Bowdoin neighborhoods. Another 16 percent or so went up between 1960 and 1979, and roughly 27 percent is from 2000 or later. About 71 percent of occupied homes are owner-occupied, and only about half of all units are single-family detached houses, which reflects the apartments, student housing and multi-unit buildings near the college and Maine Street. Seasonal homes are a small share, about 165 units. Expect clapboard Federal, Greek Revival and Colonial Revival houses in the historic districts, and vinyl-clad capes, ranches and colonials farther out.

Weather and exposure in Brunswick

Brunswick is coastal on its south side and inland on its north. Mere Point, Maquoit Bay and Middle Bay put houses in the path of salt air and wind off Casco Bay, while neighborhoods near the Androscoggin and out toward Durham feel more like an inland town. The Portland Jetport, the nearest long-record National Weather Service station, averaged about 69 inches of snow a year over the 1991 to 2020 normals, and Brunswick's own climate table shows roughly 51 inches of total precipitation. Winters swing above and below freezing many times, which works water into clapboard joints, cracked caulk and shingle edges. Nor'easters drive rain sideways into the east and north walls, and the shore points take the hardest wind.

Brunswick neighborhoods and architecture

Brunswick grew on the river. The Androscoggin falls about 41 feet in three stages here, and the town once had as many as 25 sawmills and, in 1809, Maine's first cotton mill. Bowdoin College, chartered in 1794, anchors the Federal Street Historic District, listed in 1976, with Federal, Greek Revival and Colonial Revival houses, First Parish Church and the Harriet Beecher Stowe House. Pennellville, on Middle Bay Cove, preserves ship captains' houses built between 1794 and 1860. Other neighborhoods include Cooks Corner, Mere Point, Bunganuc Landing and Brunswick Landing, the former Naval Air Station that closed in 2011.

Permits and design review in Brunswick

Building permits in Brunswick go through the Planning and Codes Office at Town Hall, 85 Union Street, on paper or through the online permit portal. Maine's building code moved to the 2021 International Residential Code on April 7, 2025. Much of the historic core lies in the Village Review Overlay District, where the Village Review Board issues a Certificate of Appropriateness for alterations; the town notes that replacing windows, facades and ornamentation with identical styles and materials is not subject to review, and staff can approve minor work not visible from a public way. Waterfront lots within 250 feet of tidal areas also fall under shoreland zoning.

Codes & Permits for Exterior Work in Brunswick

In Brunswick, exterior-work permits come from the Planning & Codes Office, Town of Brunswick Dept. of Planning and Development (85 Union Street, Brunswick, ME 04011, 207-725-6660). With 21,756 residents, over 4,000, Brunswick is required to enforce the Maine Uniform Building and Energy Code (MUBEC). The Federal Street and Pennellville Historic Districts hold National Register status; exterior work visible from the street in these areas draws extra scrutiny.

  • Maine's adopted 2021 IRC requires all exterior wall coverings (siding) to be installed per the applicable code section and, where referenced, the manufacturer's installation instructions, with fastener penetration and spacing set by Table R703.3(1) — a full-envelope re-siding job (removing sheathing/house-wrap, not just cladding) is code work subject to a building permit in mandatorily-enforcing towns even where a simple like-for-like cladding swap might be treated as exempt maintenance by a given town; permit posture for the latter varies by municipality. up.codes
  • A weather-resistive barrier is required under exterior wall coverings generally (R703.2), meaning a proper re-siding job that exposes the sheathing must also address the house-wrap/felt layer, not just the visible cladding. up.codes
  • Maine's Shoreland Zoning Act creates a regulated shoreland zone extending 250 feet (horizontal distance) from the normal high-water line of any great pond, river, or coastal wetland, and 75 feet from certain streams; the Act's stated purposes include protecting buildings and land from flooding/erosion and controlling water pollution, and it governs deck and other structure setbacks and the expansion of nonconforming structures within that zone (specific setback/expansion rules are set at the municipal-ordinance level under the state's model guidelines). maine.gov
  • By Maine law (25 M.R.S. §2373), 'the code must be enforced in a municipality that has more than 4,000 residents' (per the most recent federal census); municipalities at or below that population are not required to adopt/enforce MUBEC but may opt in locally, per the state's own program page: 'All municipalities with a population greater than 4,000 are required, by statute, to enforce the MUBEC. Municipalities with a population under 4,000 may choose to enforce the MUBEC.' mainelegislature.org

How Cardinal Exteriors Handles Exterior Work in Brunswick

  • With 21,756 residents, Brunswick is over Maine's 4,000-resident line, so the town enforces the statewide Uniform Building and Energy Code (MUBEC) on top of its own permit process.
  • With 31% of Brunswick's housing built before 1960, a real share of that stock predates 1978 as well, which means EPA lead-safe containment is part of exterior work on an older Brunswick home more often than not.
  • The Federal Street and Pennellville Historic Districts hold National Register status; exterior work visible from the street in these areas draws extra scrutiny. We check whether a property falls inside that boundary before finalizing material and color.
  • Because Brunswick has coastal, lake or river frontage, Maine's Mandatory Shoreland Zoning Act may apply to work close to the water, which can affect setbacks on a rebuild.
  • We file for exterior work permits at the Planning & Codes Office, Town of Brunswick Dept. of Planning and Development before work starts, not after.

Siding in Brunswick

Windows in Brunswick

  • Window Replacement in BrunswickWith about 31 percent of Brunswick's housing built before 1960, many homes here still have original single-pane wood sashes with storm windows added over them, or early replacement windows from the 1980s whose seals have failed and fogged.
  • Bay & Picture Windows in BrunswickBrunswick's water views are mostly on the south and west sides of town, where Mere Point, Maquoit Bay and Middle Bay open up toward Casco Bay.

Roofing in Brunswick

  • Roof Replacement in BrunswickSnow, ice dams and wind drive most roof replacements in Brunswick.
  • Asphalt Shingle Roofing in BrunswickArchitectural asphalt shingles cover most of Brunswick's post-1960 houses, from the capes and colonials of the 1970s and 1980s to homes built since 2000, and they remain the most economical way to re-roof them.
  • Metal Roofing in BrunswickStanding seam and metal shingle roofs suit many Brunswick properties: farmhouses and barns on the rural roads north of town, cottages on Mere Point and Bunganuc, and newer homes whose owners want a roof that sheds snow and lasts.

Decks in Brunswick

  • Deck Building in BrunswickA new deck in Brunswick has to deal with frost, lot shape and, on the water, shoreland rules.
  • Composite & PVC Decks in BrunswickComposite and PVC decking fits the way many Brunswick homes are used.
  • Deck Replacement in BrunswickMany decks added to Brunswick houses in the 1980s and 1990s were built with pressure-treated lumber, nailed ledgers and shallow footings, and after thirty-plus Maine winters the problems add up: ledger boards that were never flashed and have rotted the rim joist behind them, posts sitting on blocks that heave in spring, and railings too low or too open for today's code.
