Limestone ground

The borough has many underground streams that have carved out limestone and formed sinkholes, and its name comes from a spring that sinks into the ground. Ground movement can crack foundations and open new air paths at the sill. We seal those gaps; structural cracks need a structural repair first.

Newer homes, specific gaps

Homes from the 1990s and 2000s are tighter than older ones, but builders do not always seal everything. Common gaps are at the rim joist, in floors over garages, around recessed lights and at the attic hatch. We seal just those places.

Finishing basements

If you plan to finish the basement, foam the rim and insulate the walls first.
