Vinyl Siding Installation in Portland, Maine

Portland has roughly 36,600 housing units, and the American Community Survey estimates a median year built of 1946. About 46 percent predate 1940 and about 61 percent predate 1960, while only about 16 percent date from 1960 to 1979 and about 11 percent from 2000 or later. Owners occupy about 47 percent of occupied homes, and single-family detached houses make up only about 36 percent of the stock, so multi-unit buildings are the norm rather than the exception. After the Great Fire of 1866 the peninsula was rebuilt largely in Victorian and Italianate styles, and wood-framed triple-deckers fill much of the older residential grid. Off the peninsula, Deering and the outer neighborhoods run to capes, colonials and mid-century houses. The census also counts nearly 1,900 seasonal units, many of them island cottages in Casco Bay.

Portland sits on a peninsula in Casco Bay, and exposure changes block to block. Houses on the eastern and western ends of the peninsula, along the harbor and on the islands take wind straight off the water, while inland neighborhoods such as Deering and Stroudwater are more sheltered. Snowfall averages about 69 inches a year, but the city has seen seasons as light as 30 inches and as heavy as 150. Severe nor'easters arrive in winter with wind-driven rain and snow that finds any gap in old clapboard, trim or window casing. Repeated freeze and thaw works on paint, caulk and shingles, and salt air on the waterfront and islands speeds corrosion of fasteners, flashing and exposed metal.

Building permits in Portland go through the city's Permitting and Inspections Department, which handles permits, licensing and inspections in one office. A new deck is structural work and needs a building permit; ask the department whether a given roof, siding or window job needs one before work starts. Portland also has a strong historic preservation ordinance. Properties in local districts including the West End, India Street, Congress Street, Deering Street, Stroudwater and the Old Port waterfront need a certificate of appropriateness for exterior alterations, reviewed by preservation staff or the Historic Preservation Board. Waterfront and island lots may also fall under shoreland zoning.

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
