Kennebunk runs from the inland Kennebunk Plains and West Kennebunk to the ocean at Kennebunk Beach, Gooch's Beach and the Lower Village, and it was a shipbuilding center until 1918, leaving many historic shipbuilders' homes.
The houses in Kennebunk
44% of the homes in Kennebunk are older than 1980 and 19% older than 1940; the median one dates from 1983; 65% are detached houses and 81% 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.
By the owners' own estimate, the median owned home in Kennebunk is worth about $487,700. 58% of homes have three or more bedrooms, and each bedroom needs an emergency escape opening under the egress rule.
Half the homes in Kennebunk were built before 1983, which makes its housing about 3 years newer than across York County as a whole (median 1980). Set against York County as a whole, owners live in 81% of occupied homes here against 77% county-wide, the median owner-estimated value is $487,700 here and $395,700 across the county and detached houses are 65% of the homes, below the county's 70%.

What that vintage turns up
The largest group of homes in Kennebunk, 32% 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 25% 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
Kennebunk has 3 listed: Kennebunk Historic District, Lower Alewive Historic District and Kennebunk Historic Preservation Overlay District (local). 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.

The rules in Kennebunk
Siding replacement Conditional
It depends on the job. Kennebunk requires a building permit for the construction or alteration of any building, but says repairs such as replacing loose siding do not need one; whole re-sides appear on the town's issued-permit report under exterior remodels.
Window replacement, same opening Permit required Enlarging or cutting an opening Permit required
The town's FAQ answers 'Do I need a permit for replacement windows and doors?' with "Yes. The State Model Energy Code requires windows and doors to meet current standards."
Maine sets this, not Kennebunk: U-0.30 or lower
With 11,536 residents in the 2020 Census, Kennebunk is over the 4,000 mark at which Maine requires a town to enforce the state's building and energy code. The town's FAQ ties replacement windows and doors to the energy code: they have to meet current standards.
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
Every permit has a $45 application processing fee, and building permits have a $40 minimum.
Local quirks
In Kennebunk's Historic Preservation Overlay District, created in 1963, no building permit for exterior work is issued until the Historic Preservation Commission grants a certificate of appropriateness.
