South Berwick, set off from Berwick in 1814, has some of the oldest houses in the area, including the Sarah Orne Jewett House of 1774 on Central Square and the Federal-style Hamilton House of about 1785. Its village center was listed on the National Register in 2010, and the town lies along the Salmon Falls River on the New Hampshire line.
The houses in South Berwick
44% of the homes in South Berwick are older than 1980 and 22% older than 1940; the median one dates from 1982; 77% are detached houses and 78% of occupied homes are owner-occupied. 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 $428,300, and 66% of homes have three bedrooms or more — each bedroom needs an emergency escape opening under the egress rule.
Half the homes in South Berwick were built before 1982, which makes its housing about the same age as across York County as a whole (median 1980). Set against York County as a whole, owners live in 78% of occupied homes here against 77% county-wide, the median owner-estimated value is $428,300 here and $395,700 across the county and detached houses are 77% of the homes, above the county's 70%.

What that vintage turns up
The largest group of homes in South Berwick, 38% 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 22% built before 1940
Nothing behind the boards sheds water: no house wrap and no flashing at the window heads, only paint and trim. A new window set into that wall needs a sill pan and head flashing improvised into old framing, so ask how the installer will lap it before you compare prices.

Historic districts
South Berwick has 1 listed: South Berwick Village 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
South Berwick shares a boundary with Berwick, North Berwick, Wells, York, Eliot, Rollinsford, New Hampshire, Dover, New Hampshire and Salmon Falls River.

The rules in South Berwick
Siding replacement No permit
No. South Berwick's Code Enforcement page lists "Replacing vinyl siding, clapboards, or other, like siding" among the work that needs no permit. The word that matters is like: changing the kind of siding is not on the list.
Window replacement, same opening No permit Enlarging or cutting an opening Permit required
The same list includes "Replacement windows, not requiring reframing." Reframing for a new or bigger opening needs a permit.
Maine sets this, not South Berwick: U-0.30 or lower
With 7,467 residents in the 2020 Census, South Berwick 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
The same page warns that if a home is in the Historic District, or within 1,500 feet of a historic property, special circumstances apply; in the Village Center and Liberty Street historic districts any change in a building's exterior appearance needs a Certificate of Appropriateness, with samples of any siding proposed.
