Bethlehem sits just east of Allentown along the Lehigh River and straddles two counties, Lehigh and Northampton. That matters more than people expect, because permits and inspections for drainage or foundation work go through the City of Bethlehem rather than Allentown, and the contractor needs to know which office to deal with.
Homeowners in Bethlehem call for the same problems seen across the valley: seepage at the floor joint after storms, sump pumps that can't keep up, and older walls that let water through the mortar. If your house is close to the river or a creek, mention that in your request, since high groundwater calls for a different fix than a single leaking crack. Ask the company for its Pennsylvania home improvement contractor registration number and proof of insurance before you sign anything.
