Siding Replacement in Falmouth, Maine

Census estimates for 2020 to 2024 count about 5,300 housing units in Falmouth, with a median year built of 1986. Roughly 14 percent went up before 1940, about 16 percent between 1960 and 1979, about 31 percent in the 1980s and 1990s, and about 27 percent in 2000 or later. Around 84 percent of occupied homes are lived in by their owners, and about 81 percent of all units are single-family detached houses; the town's 2024 comprehensive plan notes that fewer than 10 percent sit in buildings of three or more units. An older layer runs underneath the subdivisions: a 1992 to 1993 survey recorded 985 buildings from before 1945, including farms, schools and summer homes in colonial, Federal, Greek Revival, Italianate and Romanesque styles. About 190 units are held for seasonal use.

Falmouth has no weather station of its own; the nearest long-term record is Portland International Jetport, a few miles away, where snowfall averages about 69 inches a year and February nights average around 17 degrees under the 1991 to 2020 normals. The coldest reading on that record is 39 below zero, in February 1943. Along Falmouth Foreside, houses face open water on Casco Bay and take the brunt of northeast storms, wind-driven rain and salt carried off the bay. Inland toward West Falmouth and Highland Lake the salt load drops, but tree cover, lake humidity and long stretches of freezing and thawing work on roofs, trim and deck boards instead.

Permits come from the Community Development Code Enforcement Division at 271 Falmouth Road. The town enforces the Maine Uniform Building and Energy Code, which means the 2021 International Residential, Building, Existing Building and Energy Conservation Codes. Its permit guidance says work that alters or repairs a structure needs a building permit, and it specifically requires one for replacement windows so egress can be checked. Painting and similar finish work is exempt; roofing, siding and decks are not on the exempt list. Shoreland zoning covers land within 250 feet of Casco Bay, the Presumpscot River, Highland Lake and qualifying wetlands, and within 100 feet of designated streams.

Siding replacement is more than new cladding. The old siding comes off, the sheathing underneath is inspected and repaired where it has gone soft, a new weather-resistive barrier and flashing go on around every opening, and the new siding and trim are installed as one system. In Maine, where wind-driven rain, freeze-thaw cycles and long winters test every seam, the layers you never see decide how long the wall lasts.

• An owner walks the house, measures every wall, and notes rot, past leaks, and how many layers of old siding are on it.
• Old siding and trim are stripped to the sheathing, and damaged boards are cut out and replaced before anything new goes on.
• A house wrap or other weather-resistive barrier is lapped shingle-style, with flashing tape and head flashing at windows and doors.
• New corner boards, window and door casing, and frieze trim go up, then the siding itself, fastened to the manufacturer's spacing.
• Debris is hauled away, magnetic sweeps pick up nails, and the job is walked with you before the last crew leaves.

• Clapboards or shingles that are cupped, split, or soft when pressed
• Paint that peels within a few seasons of being painted
• Stains, mold, or bubbling paint on interior walls after storms
• Dated aluminum, asbestos-cement or 1970s metal siding you want gone
• Rooms that feel drafty along exterior walls

• Wall area and how many stories need staging or lifts
• How many layers of old siding come off, and whether any need special handling
• Sheathing repairs found once the old siding is off
• The siding material chosen: vinyl, fiber cement, cedar or composite
• Trim detail: corner boards, window casing, frieze boards and brackets
• Whether windows or the roof are replaced in the same visit
