What that vintage turns up

The largest group of homes in Sebago, 25% 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 20% 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.

The rules in Sebago

Siding replacement Not published

Sebago's permits page lists the work that needs no permit as roofing, exterior painting, interior painting and wallpapering, and siding is not on it. The Land Use Ordinance requires a Code Enforcement Officer permit for alterations such as decks and porches. Ask before a re-side.

Window replacement, same opening Not published Enlarging or cutting an opening Permit required

Window replacement is not on the no-permit list either. A new or enlarged opening is an alteration under the ordinance.

Maine sets this, not Sebago: U-0.30 or lower

Sebago counted 1,911 residents in the 2020 Census, under the 4,000 mark, so it need not enforce the state's code, and its pages do not say it does; the state still counts meeting the code as the owner's responsibility.

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.

Common questions about Sebago

What age of house is typical in Sebago?

25% went up in the 1980s and 1990s and 20% in 2000 or later; the median Sebago home dates from 1975, and 55% are older than 1980 (17% older than 1940). ACS 2020–2024.

Does Sebago require a permit for new siding or windows?

No rule is published. Sebago's rules say nothing on whether you need a permit to re-side or to replace a window in the same opening and require a permit to cut or enlarge an opening. Sebago's permits page lists the work that needs no permit as roofing, exterior painting, interior painting and wallpapering, and siding is not on it. Next door in Bridgton, a re-side needs no permit.

How energy-efficient does a new window have to be in Sebago?

Maine sets it statewide, not Sebago: a U-factor of 0.30 or lower under the 2021 energy code Maine adopted, with no limit on solar heat gain. Sebago counted 1,911 residents in the 2020 Census, under the 4,000 mark, so it need not enforce the state's code, and its pages do not say it does; the state still counts meeting the code as the owner's responsibility.

What does the egress rule mean for windows in Sebago?

Yes. 55% of Sebago's homes have three or more bedrooms (median owner-estimated value $298,000), and each bedroom needs an emergency escape opening: at least 5.7 square feet of net clear opening (5 at a grade-floor sill), 24 inches high and 20 inches wide, with the sill no more than 44 inches above the floor (IRC R310).
