Vinyl Siding Installation in Casco, Maine

Census estimates count about 2,970 housing units in Casco, with a median year built of 1988, noticeably newer than Raymond's 1976. Only about 5 percent predate 1940 and around 18 percent predate 1960, while roughly 31 percent have gone up since 2000. About 76 percent are single-family detached homes, a lower share than in neighboring Raymond, and about 90 percent of occupied homes are owned by the people living in them. Seasonal use is large: roughly 1,210 units, about four in ten, are held for seasonal or recreational occupancy, from shoreline cottages to second homes. The town also runs a short-term rental registration ordinance, since many lake houses are rented by the week. The older layer is small but real, including a Federal-style house from about 1795 in South Casco.

Casco is inland, so the weather that wears on houses here is snow, cold and the wind off big water, not salt. Published normals from the National Weather Service office in nearby Gray show about 84 inches of snow a year for 1991-2020, well above the roughly 69 inches at the Portland Jetport. Deep cold and midwinter thaws alternate from December into March. Cottages on the north shore of Sebago Lake face miles of open water to the south, and Sebago rarely freezes over completely, so that exposure lasts through the winter. Houses on Pleasant Lake, Thomas Pond and the smaller ponds sit among tall pines, where shade and needle litter keep roofs and decks damp.

Casco's Code Enforcement Department, which the town calls its building department, works from the town office at 635 Meadow Road and meets by appointment. Since April 7, 2025 the town enforces the 2021 I-codes under Maine's uniform building code. The building permit application asks whether a lot is in shoreland, water body, wetland or resource protection zoning, wants a plot plan with roadside and lakeside setbacks, and records lot coverage. Permits are valid for one year. Work in the shoreland zone, within 250 feet of a great pond, uses a separate Shoreland Project Permit Application with photos before and after construction.

Premium vinyl siding is the fastest way to a tight, low-maintenance exterior. Today's thicker panels come in clapboard, Dutch lap, board-and-batten and shake profiles and in colors that were not possible a generation ago. The projects shown on this site include CertainTeed Monogram vinyl siding, used to replace rotting wood clapboards and 1970s metal siding on Portland homes. Vinyl moves with temperature, so how it is hung matters as much as which panel you pick.

• Old siding is removed and the wall is checked for soft sheathing and past leaks.
• House wrap and flashing go on first, with extra care around windows, doors and roof-to-wall joints.
• Starter strip, J-channel and corner posts are set straight and level so every course lines up.
• Panels are nailed in the center of the slots and left loose enough to expand and contract through a Maine winter and summer.
• Trim is wrapped or replaced with low-maintenance millwork so there is nothing left to paint.

• You are tired of repainting wood clapboards every few years
• The existing vinyl is faded, cracked, or loose after wind storms
• The budget needs a whole-house result rather than one premium wall
• You want an insulated panel to take the edge off drafty walls

• Panel grade and thickness, and whether it is insulated
• Profile: clapboard, Dutch lap, board-and-batten or shake
• Amount of trim, soffit and fascia wrapped or replaced
• Tear-off and sheathing repairs
• House height and access
