A historically rural farm and mill town that has grown into a bedroom community of Portland. It is home to the Gorham campus of the University of Southern Maine, where the Federal-style Academy Building dates to 1806, and its old Presumpscot River mill sites now lie under the Dundee Dam pond.
The houses in Gorham
Of the homes in Gorham, 38% predate 1980 and 14% predate 1940; the median one dates from 1988. Detached single-family houses make up 80%; owners live in 81% 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.
By the owners' own estimate, the median owned home in Gorham is worth about $460,900. 69% of homes have three or more bedrooms, and each bedroom needs an emergency escape opening under the egress rule.
Half the homes in Gorham were built before 1988, which makes its housing about 12 years newer than across Cumberland County as a whole (median 1976). Set against Cumberland County as a whole, owners live in 81% of occupied homes here against 70% county-wide, the median owner-estimated value is $460,900 here and $451,200 across the county and detached houses are 80% of the homes, above the county's 63%.

What that vintage turns up
The largest group of homes in Gorham, 33% of them, was built in 2000 or later, so that is the house described here.
Double-glazed low-e vinyl or fiberglass windows, usually installed with flashing tape over a house wrap. These rarely need replacing for age; when one fails it is usually a seal or a piece of hardware, and the maker's warranty is worth checking before anything else. Heavy frost or water on the inside of the glass in a cold snap is more often a humidity problem in a tight house than a window defect.
Vinyl, fiber cement or engineered wood over oriented strand board and a house wrap, the wall assembly the current code expects. The weak points are workmanship, not materials: tape that let go at the window corners, a missing kickout where a roof edge meets a sidewall, J-channel run tight with no room for the siding to move.
The one to watch on a house of this age
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.
And on the 29% built in the 1980s and 1990s
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.

Historic districts
Gorham has 3 listed: Gorham Historic District, Gorham Campus Historic District and South Street Historic District. 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
Gorham shares a boundary with Windham, Standish, Buxton, Scarborough, Westbrook and Presumpscot River.

The rules in Gorham
Siding replacement Permit required
Yes, by the town's own rule. Gorham's Code Division says any alteration to an existing structure requires a building permit, and its land use code requires one before a building is structurally altered. Neither names siding, so confirm with the Code Enforcement Officer.
Window replacement, same opening Permit required Enlarging or cutting an opening Permit required
The same rule reaches window replacement and, plainly, any new or enlarged opening.
Maine sets this, not Gorham: U-0.30 or lower
With 18,336 residents in the 2020 Census, Gorham 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.
What the permit costs
Alterations are charged $12 per thousand dollars of labor and materials, with a $50 minimum.
Local quirks
Gorham's code handout gives the bedroom egress rule: a sill no more than 44 inches above the finished floor and a bottom sash that opens to at least 5.7 square feet, 20 inches wide and 24 inches high. In the Gorham Village Center District, street-facing exteriors are to be traditional New England materials or materials that replicate them, such as vinyl clapboard, and products such as T1-11 or plywood are barred on facades visible from a public street.
