Composite & PVC Decks for Freeport homes
Composite and PVC boards suit Freeport's shore and seasonal homes, some 280 of which are held for occasional use, because they skip the yearly washing, sanding and staining that wood needs. Capped composite boards resist salt, sun and moisture far better than the early products that stained and faded, and PVC boards take on almost no water, which helps on a deck near the Harraseeket that catches fog and spray. Hidden fasteners leave a clean surface for bare feet.
Shade is the other factor. A deck under oaks and pines on a wooded lot stays damp longer, and mildew grows on any surface that does not dry, composite included, so board color, spacing and airflow underneath all matter. Darker boards get hot in full sun, while lighter ones stay cooler on a south-facing deck. Composite still sits on a wood frame, so the structure below needs the same care as a wood deck: joist spacing matched to the board, ground-contact lumber for posts and beams, and flashing tape on joist tops. Freeze-thaw moves boards, so gapping to the maker's spec prevents buckling. Composite railings, fascia and stair treads can match the surface.

How a Deck Structure Is Built
- Footing — poured below Maine’s frost line so winter heaving cannot move it
- Post — carries the beam load down to the footing
- Beam — spans between posts and carries the outer ends of the joists
- Ledger — bolted to the house framing, with flashing that diverts water away from the wall
- Joists — span from the ledger to the beam, sized and spaced to the decking and the load
- Decking — the walking surface, fastened on top with spacing for drainage

Freeport housing at a glance
Census estimates (ACS 2020-2024) put Freeport at roughly 4,250 housing units with a median year built of 1984, young for a town incorporated in 1789: about 17 percent of homes predate 1940 and about a quarter predate 1960; another 18 or 19 percent went up between 1960 and 1979, and roughly 30 percent were built in 2000 or later, leaving about a quarter from the 1980s and 1990s. Around 72 percent are single-family detached houses, close to 78 percent of occupied homes are owner-occupied, and some 280 units are held for seasonal use. The oldest stock is Federal and Greek Revival: the c. 1790 Mitchell-Soule-Davis cape and the c. 1830 brick Harrington House survive on Main Street, and saltbox farmhouses such as the Pettengill House and the Capt. Greenfield Pote House stand near Mast Landing and on Wolfe's Neck. Newer neighborhoods fill in between Route 1, I-295 and the river.
Permits and design review in Freeport
Building permits come from the Codes Enforcement office at Freeport Town Hall, 30 Main Street. A permit is required for any structural work or change of use, alterations may need one too, and the town asks owners to check with the codes officer first; a complete residential application is usually approved within a week. The residential checklist asks deck applicants for pier locations, framing, fastening, guards, handrails and stairs, and asks for a window and door schedule with U-factors. Downtown renovations fall under the Design Review Ordinance and the Project Review Board, and land within 250 feet of tidal water or a coastal wetland is in the state shoreland zone.
Weather and exposure in Freeport
Freeport sits at the northeastern corner of Casco Bay, and the Harraseeket River carries the tide inland past South Freeport, Porter's Landing and Mast Landing. Houses on Wolfe's Neck, in South Freeport and along the river take salt air, fog and northeast wind off the bay in nor'easters, while homes west of I-295 sit in more sheltered, wooded country. Snow is a real load here: Portland International Jetport, the nearest long-record weather station, averages about 69 inches a season under the 1991-2020 normals, most of it from December through March. Winters swing above and below freezing again and again, so water that gets behind trim, into siding joints or under shingles freezes, expands and works deeper with each cycle. Ice dams form on poorly insulated older roofs.

Codes & Permits for Composite Decks in Freeport
In Freeport, exterior-work permits come from the Freeport Codes Enforcement (30 Main Street, Freeport, ME 04032, 207-865-4743). With 8,737 residents, over 4,000, Freeport is required to enforce the Maine Uniform Building and Energy Code (MUBEC). The Harraseeket and Freeport Main Street Historic Districts cover the village's maritime and commercial core.
- Maine's adopted 2021 IRC (R507.2.2) requires plastic composite deck boards, stair treads, guards, and handrails to comply with ASTM D7032, and (R507.2.2.1) to be labeled with the allowable load and maximum allowable span determined under ASTM D7032 — meaning composite span limits come from the product's own ASTM D7032 listing/manufacturer data rather than the standard wood joist-span tables, and are often shorter, requiring closer joist spacing than an equivalent wood board. up.codes
- Composite decking installation must follow both the code and the manufacturer's instructions (R507.2.2.5), so a given product's specific fastening pattern and joist spacing should be pulled from its ICC-ES evaluation report or manufacturer install guide, not assumed from a generic wood-deck spec. 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 Composite Decks in Freeport
- Maine's adopted deck code (R507.2.4) requires a corrosion-resistant ledger flashing at least 0.019 inch thick, or an approved nonmetallic equivalent — every ledger-attached deck we build in Freeport gets it.
- We set every Freeport deck's footings below frost depth and size them to the actual load, following Maine's adopted residential code rather than a rule of thumb.
- Because Freeport 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.
- With 8,737 residents, Freeport 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.
- Anything that needs a permit for composite and PVC decks goes through the Freeport Codes Enforcement.

What composite and PVC decks involves
Composite and PVC decking do not need staining, do not splinter, and resist rot, which is why they have become the default for new decks in Maine. Composite boards blend wood fiber and plastic under a protective cap; PVC boards are all synthetic and lighter. The North Deering farmhouse on this site got a rebuilt deck with AZEK composite decking. The framing underneath is still wood, so it is built to last as long as the boards on top.
- Layout, size and board color are chosen with the owner at the estimate visit.
- Footings and framing are built to code, with joist spacing that suits the board manufacturer's span rules.
- Joist tape or flashing protects the tops of joists and the ledger.
- Boards go down with hidden fasteners or color-matched screws and the expansion gaps the product requires.
- Matching railings, stair treads, fascia and landings finish the deck.
Signs it is time
- You are done staining and sealing a wood deck every year or two
- The deck is in shade or near water where wood stays damp
- You want a deck that stays barefoot-friendly with no splinters
What affects the price of composite and PVC decks
