A small borough

Clarks Summit was incorporated on August 30, 1911, and covers about 1.6 square miles. The 2020 census counted 5,108 residents, and the median household income was $87,102. The oldest standing house, the former Snook family home on South State Street, was built in 1837.

Mid-century homes

Ranches, split-levels and colonials from the 1960s and 1970s usually have some attic insulation, often thin and settled, plus bare rim joists and leaky attic hatches. Attic sealing, cellulose to R-49 or more and rim joist foam are the usual plan. Walls often have batts that have slumped; we check before quoting.

Older homes

The pre-war houses in Clarks Summit get the full old-house treatment: wall-top blocking, attic sealing, dense-pack walls and sill foam.

Higher ground

Clarks Summit sits north of Scranton on higher ground above the valley. Winters here bring plenty of snow, and ice dams are common on houses that leak heat into the attic.

Code and zone

Pennsylvania's 2021 UCC took effect January 1, 2026. Lackawanna County is in PHRC's Central zone and OpenEI's Zone 5A. DOE recommends R-60 for an uninsulated Zone 5 attic, or adding R-49 over 3 to 4 inches.

Costs

A typical Clarks Summit job

For a 1960s ranch or split-level, a common plan is: seal the attic floor and top up to R-49 or more, foam the rim joist, and dense-pack any walls where batts have slumped. For an older colonial or Victorian, add wall-top blocking and full dense-pack walls.
