Bay & Picture Windows for Gorham homes
Gorham houses on larger lots often look out over woods, yards or the river valleys of the Presumpscot and Stroudwater, and a picture window turns that outlook into the focal point of a living room. A single large fixed pane has no sashes to leak air, so it can outperform the smaller operable windows it replaces, and pairing it with casements or awning windows on each side keeps some ventilation.
Bay and bow windows project from the wall and bring light in from three directions, which suits a dark north-facing room in winter. Because a bay has its own small roof, it collects snow and needs flashing and ice-barrier underlayment like the main roof; bays that sag or leak usually lack proper support below or flashing above. Safety glass is required by code in large panes close to floors and doors. On the historic houses of Gorham Village, a new bay on a street-facing wall changes the house's appearance and may require historic review, while a rear elevation usually has more freedom. Cardinal installs picture, bay and bow units in vinyl, wood and clad materials.

How a Window Rough Opening Gets Flashed
- Sill pan — sloped, with dammed ends, so any water that gets past the window drains out, not into the wall
- Window unit — set directly on the sill pan before the sides are fastened
- Jamb flashing tape — laps over the sill pan on both sides, in the order water will travel
- Head flashing — tucks under the weather-resistive barrier above the opening
- Drainage — every layer sheds down and out, never behind the one below it

Gorham housing at a glance
Gorham counts about 6,800 housing units in the 2020 to 2024 Census estimates, with a median year built of 1988. Roughly a third of homes, about 33 percent, were built in 2000 or later, and about 29 percent date from the 1980s and 1990s, so most of the town's houses are under 45 years old. The older layer is substantial: about 14 percent of homes predate 1940 and about 21 percent predate 1960, including the wooden 19th-century houses of the Gorham Village historic district. Another 17 percent or so went up between 1960 and 1979. About 80 percent of homes are single-family detached and about 82 percent of occupied homes are owner-occupied. The estimates show essentially no seasonal housing, so nearly every house here is lived in year-round.
Gorham neighborhoods and architecture
Gorham was first settled in 1736 and incorporated in 1764. Gorham Village is the town center, with South Gorham, West Gorham, North Gorham, Little Falls and White Rock beyond it. The Gorham Historic District, listed on the National Register in 1992, covers about 25 acres and 42 historic buildings, mostly wooden houses in the Federal, Greek Revival and Italianate styles, with brick commercial blocks on School Street; the First Congregational Church dates from 1797. Next door, the Gorham Campus Historic District holds the University of Southern Maine campus, which grew from Gorham Academy, founded in 1806. The McLellan House, Baxter House and Stephen Longfellow House are also on the Register.
Permits and design review in Gorham
Permits in Gorham are handled by the Code Division of the town's Community Development department, and applications are now filed online through the SmartGov system. The town lists a Building Permit for Minor Projects that covers decks, sheds and pools, so a new deck or a deck replacement is permitted before construction; ask the Code Division whether a roofing, siding or window job needs one. Lots along the Presumpscot and other rivers fall under shoreland zoning and need a Shoreland Zoning Permit for work in that zone. Gorham also has a Historic Preservation Commission, which issues Historic Preservation Certificates for designated historic properties and districts.

Codes & Permits for Bay & Picture Windows in Gorham
In Gorham, exterior-work permits come from the town's code office. With 18,336 residents, over 4,000, Gorham is required to enforce the Maine Uniform Building and Energy Code (MUBEC). The Gorham Historic District, reviewed by the town's Historic Preservation Commission, covers part of Gorham Village.
- A fixed picture window does not itself satisfy IRC R310 egress for a bedroom; if a bay/picture window is installed in a sleeping room, the room still needs a separate code-compliant egress window or door meeting the R310 opening/sill dimensions elsewhere in the room. up.codes
- Bay windows project beyond the wall plane and typically require additional structural support (headers sized per the applicable IRC span tables, and often a knee-wall or bracket support system) beyond what a standard flat-wall window opening needs — sizing should follow the IRC's header/span-table provisions and, for the bay's roof/floor cantilever, engineered or manufacturer-specified support rather than a simple in-wall header swap. up.codes
- The same Climate Zone 6A / U-factor 0.30 fenestration requirement applies to bay and picture window units as to standard replacement windows under Maine's adopted 2021 IECC. up.codes
- Maine's Shoreland Zoning Act creates a regulated shoreland zone extending 250 feet (horizontal distance) from the normal high-water line of any great pond, river, or coastal wetland, and 75 feet from certain streams; the Act's stated purposes include protecting buildings and land from flooding/erosion and controlling water pollution, and it governs deck and other structure setbacks and the expansion of nonconforming structures within that zone (specific setback/expansion rules are set at the municipal-ordinance level under the state's model guidelines). maine.gov
How Cardinal Exteriors Handles Bay & Picture Windows in Gorham
- Maine's adopted energy code places Gorham in Climate Zone 6A, capping the U-factor on replacement windows at 0.30 — every unit we quote for a bay and picture windows job here meets that number or beats it.
- At least 21% of Gorham's homes predate 1960 — well ahead of 1978, when the EPA's lead-safe renovation rule kicks in — so we plan for lead-safe work practices on bay and picture windows whenever painted surfaces come off an older house here.
- The Gorham Historic District, reviewed by the town's Historic Preservation Commission, covers part of Gorham Village. We check whether a property falls inside that boundary before finalizing material and color.
- With 18,336 residents, Gorham is over Maine's 4,000-resident line, so the town enforces the statewide Uniform Building and Energy Code (MUBEC) on top of its own permit process.
- We confirm Gorham's permit process directly with the town before bay and picture windows starts.

What bay and picture windows involves
Picture windows are large fixed units that frame a view and pour light into a room. Bay and bow windows project out from the wall, adding floor space and light from three or more directions. Both are heavier and more exposed than an ordinary window, so the structure, support, roof and flashing around them matter. The Cumberland Center colonial on this site received Andersen 400 Series bay, double-hung and picture windows.
- The opening, header and framing are checked; widening an opening may need a new header.
- Bay and bow units are supported with cables, brackets or a framed seat so they do not sag.
- The small roof over a bay is flashed into the wall and roofed or capped to match the house.
- Insulation goes into the seat and head so the projection is not a cold spot.
- Interior seat boards, casing and exterior trim are finished to match.
Signs it is time
- A view you want to see more of from the main living space
- An old bay that sags, leaks at the roof, or feels cold at the seat
- Fogged glass in a large fixed unit
- A dark room that needs more daylight
