Most leaking basements around Allentown are concrete block or older stone, and water tends to come in where the wall meets the floor rather than through one obvious crack. The common fix is an interior drain: the contractor opens a strip of floor along the walls, sets a perforated pipe in clean stone, and runs it to a sump pit. A pump then pushes the water out through a discharge line to the yard.
Because it's done from inside, nobody has to dig around the house or tear up landscaping, and it also catches water pushing up through the slab. Ask whether the quote includes a battery backup pump, where the discharge line will end, and how the floor will be patched. A clear quote spells out the length of drain, the pump model and the warranty, and says whether the warranty transfers if you sell the house.
