Bay & Picture Windows for Scarborough homes
Scarborough offers more to look at than most towns in the county: the open grass and tidal channels of the 3,200-acre marsh, Saco Bay from Pine Point and Prouts Neck, and the beach at Higgins Beach. A fixed picture window takes in that kind of view with no sashes or muntins in the way, and a bay or bow window pushes the glass out from the wall so a room gains side views up and down the shore or across the marsh.
Large glass on an exposed wall needs to be sized for the wind it will face. Units near the water should carry a design-pressure rating suited to the site, and panes near floors and doors must be safety glass under the residential code. A bay window's small roof collects snow and ice like any other roof, so it needs its own flashing, underlayment and a solid support system below; a sagging bay usually traces back to inadequate support rather than the window. West- and south-facing glass over the marsh gets strong afternoon sun, and a low-emissivity coating cuts heat and fading. Cardinal installs picture, bay and bow units in wood, clad and vinyl, and one of the owners measures the opening before a price is written.

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

Scarborough housing at a glance
Census estimates for 2020 to 2024 put Scarborough at about 11,100 housing units with a median year built of 1988, a young housing stock for a town settled in 1635. About 30 percent of homes date from 2000 or later and roughly another 31 percent from the 1980s and 1990s, so a large share of houses are reaching the age when original roofs, builder-grade windows and first-generation siding come due together. About 24 percent went up between 1960 and 1979. The older layer is thinner but distinctive: about 16 percent of homes predate 1960 and about 8 percent predate 1940, including the summer cottages of Prouts Neck, many of which have changed little in more than a century. Roughly 69 percent of homes are single-family detached, about 77 percent of occupied homes are owner-occupied, and some 850 units are held for seasonal use.
Scarborough neighborhoods and architecture
Scarborough was settled in 1635 and incorporated in 1658, and it grew as a string of separate places rather than around one downtown: Pine Point, Higgins Beach and Prouts Neck on the shore, and Dunstan, Oak Hill, Eight Corners, North Scarborough and West Scarborough inland. Prouts Neck, first called Black Point, became a summer colony of Shingle-style cottages, many designed by Maine architect John Calvin Stevens. In 1884 he reworked a carriage house there into Winslow Homer's studio, now a National Historic Landmark owned by the Portland Museum of Art. The 3,200-acre Scarborough Marsh is fed by the Nonesuch, Libby and Dunstan rivers. Other National Register listings include the Dunstan Methodist Episcopal Church and the Richard Hunniwell House.
Permits and design review in Scarborough
Building permits in Scarborough go through the Code Enforcement division of the Planning and Codes Department, which applies the 2021 Maine Uniform Building and Energy Code and its residential code. The town's code FAQ says anyone who intends to construct, alter or repair a building must first obtain the required permit, so new decks and deck replacements are permitted before work starts; ask the office about roofing, siding and windows. Lots near the shore, marsh or rivers fall under Shoreland Zoning Ordinance 405C, and any development in a FEMA Special Flood Hazard Area needs a flood hazard permit, a condition of the town's membership in the National Flood Insurance Program.

Codes & Permits for Bay & Picture Windows in Scarborough
In Scarborough, exterior-work permits come from the Town of Scarborough Planning & Codes Department (Scarborough Municipal Building, Lower Level Room 125, 259 U.S. Route 1, Scarborough, ME 04070 (mailing: PO Box 360, Scarborough, ME 04070-0360), 207-730-4040). With 22,135 residents, over 4,000, Scarborough is required to enforce the Maine Uniform Building and Energy Code (MUBEC).
- 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 Scarborough
- Whatever we install for a bay and picture windows job in Scarborough is rated to Climate Zone 6A's 0.30 maximum U-factor, the energy-code ceiling Maine adopted statewide.
- With 16% of Scarborough's housing built before 1960, a real share of that stock predates 1978 as well, which means EPA lead-safe containment is part of bay and picture windows on an older Scarborough home more often than not.
- Scarborough's population (22,135) puts it above the threshold where Maine law requires full MUBEC enforcement, so this job is inspected against that code as well as the local permit.
- Anything that needs a permit for bay and picture windows goes through the Town of Scarborough Planning & Codes Department.

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
What affects the price of bay and picture windows
