A farming town settled by families from Gloucester, Massachusetts, and home to Sabbathday Lake Shaker Village, founded in 1783 and the last Shaker community still run by the Shakers themselves. The old town center is the New Gloucester Historic District.
The houses in New Gloucester
Of the homes in New Gloucester, 35% predate 1980 and 11% predate 1940; the median one dates from 1991. Detached single-family houses make up 70%; owners live in 83% of the occupied ones. A sizable share of homes here date from before 1980, the era the federal lead rule covers (homes built before 1978). What the lead rule requires of a contractor.
Owners here put the median home's value at about $357,100, and 63% of homes have three bedrooms or more — each bedroom needs an emergency escape opening under the egress rule.
Half the homes in New Gloucester were built before 1991, which makes its housing about 15 years newer than across Cumberland County as a whole (median 1976). Set against Cumberland County as a whole, owners live in 83% of occupied homes here against 70% county-wide, the median owner-estimated value is $357,100 here and $451,200 across the county and detached houses are 70% of the homes, above the county's 63%.

What that vintage turns up
The largest group of homes in New Gloucester, 33% of them, was built in the 1980s and 1990s, so that is the house described here.
Double-glazed vinyl or clad wood windows with a nailing fin, many now thirty or forty years old. The common failure is the seal between the panes: once it lets go the glass fogs between the layers and the gas fill is gone. When the frames are still square and dry, new sealed glass in the old frame is the cheaper repair; when the frames are cracked or the sills are soft, it is time for the whole unit.
The capes, colonials and raised ranches of the subdivisions that spread across the commuter towns, sided in vinyl or cedar clapboard over plywood or particle-board sheathing, with felt paper or an early house wrap behind it. The siding itself usually holds up; what to look at is what water has done at the corners, around the windows and under any deck ledger fastened through the siding.
The one to watch on a house of this age
Windows of this era were often sealed to the wrap with caulk and little else. When the siding comes off, check the sheathing below each window's lower corners: that is where a failed caulk joint shows up first, as dark, soft wood.
And on the 31% built in 2000 or later
Houses built to recent Maine codes are tight, and Maine now holds new houses to a lower air-leakage limit than the national code. A tight house with too little ventilation fogs its windows all winter; before blaming the glass, check the humidity and the bath and kitchen fans.

Historic districts
New Gloucester has 2 listed: New Gloucester Historic District and Shaker Village. A National Register listing on its own does not limit what you fit; a local district or landmark designation can, and in several towns here a change of siding material or window sash needs a certificate before the permit. Which towns' rules bind, and how.
Next door
New Gloucester shares a boundary with Gray, Raymond, Pownal, North Yarmouth, Poland, Auburn and Durham.

The rules in New Gloucester
Siding replacement Conditional
The town's pages say two things. Its 'When do I need a permit?' handout lists roofing, siding and the replacement of windows or doors as regular maintenance with no permit fee, and says maintenance that does not alter the structure needs no permit; the 2026 Zoning Ordinance says all maintenance and repair work in New Gloucester requires a permit from the Code Enforcement Officer. Ask the CEO which applies.
Window replacement, same opening Conditional Enlarging or cutting an opening Permit required
Window replacement is on the same no-fee maintenance list. Any change in structure, a new or larger opening included, requires a permit.
Maine sets this, not New Gloucester: U-0.30 or lower
With 5,676 residents in the 2020 Census, New Gloucester is over the 4,000 mark at which Maine requires a town to enforce the state's building and energy code.
That is the 2021 energy code’s window figure, with no solar heat gain limit.
ENERGY STAR’s own figure here is U-0.22 or lower with an SHGC of 0.17 or higher, stricter than any code edition in force. When the code applies to a replacement window, and when it does not.
Local quirks
In the Historic Resource Overlay District, the ordinance asks for original siding to be kept, repaired or replaced with the same material when possible, allows aluminum or vinyl as an acceptable alternative, and requires it to go on without irreversibly damaging or hiding the building's architectural features.
