Siding Replacement in Biddeford, Maine

Biddeford's median home dates to about 1952, with roughly 41 percent of the housing stock built before 1940 and 56 percent before 1960, among the oldest profiles of any town in this service area. That reflects the mill era: dense triple-deckers, duplexes and worker cottages fill the neighborhoods around the old Pepperell and Lincoln Mills downtown, many with original wood clapboard, early asbestos-cement shingle, or an aging vinyl overlay from a past renovation. Outside the mill district, West Biddeford and the areas toward Route 1 hold newer capes, ranches and colonials built through the second half of the 20th century, and Biddeford Pool adds a smaller cluster of coastal cottages and shingle-style summer homes.

The Saco River runs through downtown Biddeford before reaching the Atlantic, and Biddeford Pool, at the city's southeastern tip, takes ocean weather directly: nor'easters, wind-driven rain and salt air that accelerates corrosion of fasteners and flashing faster than it does a few miles inland. Winters bring the usual freeze-thaw cycling that works on old clapboard, paint and roof shingles all over the city, and older, poorly insulated mill-era attics are especially prone to ice damming at the eaves during a hard winter. Away from the water, exposure is more typical for coastal York County, but the age of the housing stock means storm damage often reveals problems that have been building for decades.

Building permits in Biddeford go through the Code Enforcement Office, which enters near the City Theater on Main Street, for siding, roofing, window and deck work alike. Maine's Mandatory Shoreland Zoning Act applies within 250 feet of the Saco River and Biddeford's Atlantic coastline, including Biddeford Pool and Fortunes Rocks, which restricts how close new construction and some rebuilding can sit to the water. Exterior work on buildings within the Biddeford-Saco Mills Historic District downtown can face added design review, though most residential streets in the city fall outside that district's boundary.

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
