Deck 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.

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.

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.

When an old deck is soft, wobbly or pulling away from the house, a full replacement is treated as a new build: the old deck comes off, the footings and framing are built new, and the new surface, railings and stairs go on. That is the only way to deal with hidden rot at the ledger and frost-heaved footings, and it is how Cardinal Exteriors approaches it. It lets you change the size, shape and material at the same time.

• The existing deck is removed and disposed of, and the house wall behind the ledger is inspected.
• Rotted rim or sheathing behind the old ledger is repaired and the wall is flashed.
• New footings go below frost; new posts, beams and joists are framed.
• New decking, railings, stairs and landings are installed in the material you choose.
• Permits are pulled where required and the site is cleaned up.

• Soft or spongy boards and joists
• A ledger pulling away from the house or rust-streaked fasteners
• Posts that have heaved, leaned or rotted at the base
• Railings that wobble or are lower than today's code expects

• Removal and disposal of the old deck
• Repairs to the house wall behind the ledger
