Bay & Picture Windows for Chebeague Island homes
Most Chebeague homes are within sight of salt water, and the view is often across Broad Sound, toward Cousins Island or down the bay toward Long Island and Portland. Large picture windows and projecting bays are how owners bring that into the living room. For older cottages, replacing a pair of small windows with one fixed unit flanked by operable casements is a common way to open a view without changing the character of the house.
Big glass on an exposed island has to be sized for the wind. Units need design-pressure ratings suited to coastal exposure, and the rough opening often needs a new header when a wall is widened. A projecting bay adds a small roof of its own, which must be flashed carefully to the wall and built to carry snow load, since snow drifting off the main roof tends to settle there. Orientation matters too: west-facing glass toward the mainland gets long afternoon sun, while east-facing units take the brunt of storm rain. Low-E coatings and insulated frames keep a wall of glass from turning a heated room cold in winter.

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

Chebeague Island housing at a glance
Census estimates count about 554 housing units in the town, and the median year built is 1938, which makes Chebeague one of the oldest housing stocks in Cumberland County. Roughly 51 percent of units predate 1940 and about 57 percent predate 1960. Building slowed sharply after that: only around 9 percent went up between 1960 and 1979, while about 20 percent date from 2000 or later. Nearly 97 percent of units are single-family detached houses, and about 71 percent of year-round households own their home. The defining number is seasonal use: about 263 units, close to half the total, are held for seasonal or occasional occupancy. Expect wood-frame capes and farmhouses from the fishing and stone-sloop era, cottages and former boarding houses from the summer-hotel years, and a newer layer of homes built since 2000.
Chebeague Island neighborhoods and architecture
The island is about three miles long and a mile wide, running from Chebeague Point in the north to Deer Point in the south, with North Road and South Road tying it together. Nineteenth-century islanders fished, farmed and crewed the stone sloops that carried quarried granite down the East Coast; by 1900 there were five hotels serving summer visitors who came by steamboat. The Chebeague Island Inn, built in the 1880s as the Hillcrest and rebuilt in 1925, overlooks the Stone Wharf. The Great Chebeague Golf Club, listed on the National Register in 2015, uses a Cape from about 1807 as its clubhouse, and the 1871 schoolhouse now serves as the island history museum.
Permits and design review in Chebeague Island
Building permits come from the Town of Chebeague Island Code Enforcement office, which posts its monthly permit reports online. The town's zoning ordinance says no building may be erected, structurally altered, enlarged or moved without a permit from the Code Enforcement Officer, and a new or enlarged structure needs a site plan showing the lot, buildings and yards. The town fee schedule has a separate category for decks and sheds, and fines for building without a permit start at double the fee. Shoreland overlay districts cover the waterfront, with setbacks set by the town's Shoreland Zoning Ordinance, and a dozen small islands in the town are entirely Resource Protection.

Codes & Permits for Bay & Picture Windows in Chebeague Island
In Chebeague Island, exterior-work permits come from the Town of Chebeague Island Code Enforcement Office (Paul Demers, Code Enforcement Officer) (192 North Road, Chebeague Island, ME 04017, (207) 846-3148 (office); (207) 630-8256 (cell); CodeOffice@townofchebeagueisland.org). Chebeague Island sits at or under the 4,000-resident line where MUBEC enforcement is a local option rather than a state mandate.
- 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 Chebeague Island
- Maine's adopted energy code places Chebeague Island 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 57% of Chebeague Island'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.
- Chebeague Island, at 555 residents, sits under the population line where MUBEC enforcement is a state requirement — the town may still choose to enforce it locally, and the permit process applies regardless.
- Materials cross by ferry or barge (Chebeague Transportation Company) from Cousins Island in Yarmouth, April through November. We build the schedule around that before ordering materials.
- We file for bay and picture windows permits at the Town of Chebeague Island Code Enforcement Office (Paul Demers, Code Enforcement Officer) before work starts, not after.

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
- Size and configuration: picture, bay or bow, number of units
