Finished Basements in Coopersburg, Pennsylvania

A median build year of 1958

Nearly a third of Coopersburg housing, 30.6 percent, predates 1940, and more than half of it predates 1960 (American Community Survey 2019 to 2023, table B25034). The borough covers under a square mile and was settled around 1730 as Freyburg.

The realistic Coopersburg basement is a stone or early-block cellar with headroom under seven feet, a coal-era chimney base still sitting in the middle of the floor, an original sixty to one hundred amp service, and in the 1950s houses a slab poured with no vapor barrier under it.

When the answer is not a finished basement

On a good number of these houses, reaching code-compliant ceiling height for a habitable room is not achievable without underpinning the foundation, which is a structural job with a structural price. We will tell you that on the walkthrough rather than after the deposit.

What often does make sense instead is a moisture and air-sealing package, a proper mechanical room, lighting and power brought up to current code, and a clean dry storage or hobby space. It is a smaller number and it is an honest one. This is the only page on this site where we say that, and we say it because the housing stock here warrants it.

Phasing and what it costs

Median household income in Coopersburg is $69,531, below the Lehigh County figure of $77,493, against a median home value of $282,700 (American Community Survey 2019 to 2023). Owner occupancy is 63.9 percent, the lowest of the boroughs and townships we serve.

So we phase work here more than anywhere else: dry it out and make it safe first, finish one bay properly second, add the bath or the bar later if you want them. At $75 to $125 per square foot, finishing six hundred square feet well beats finishing eleven hundred badly.

Coopersburg is its own borough with its own permit office, and the Coopersburg Historic District carries its own considerations on anything visible from the street. Schools are Southern Lehigh. Route 309 runs through the borough on Third Street.
