Fixing Basement Water in Bensalem, PA
Think of this site as a go-between. It isn't a contractor and never touches a basement; it passes your request to one independent contractor, who comes out, prices the job and does any work you hire them for. Contractors may pay this site to advertise, under a free trial for now. You pay nothing, and you won't be offered anything for reaching out.
Bensalem Township, in Bucks County about 15 miles northeast of Center City Philadelphia, counted 62,783 residents in the 2025 Census estimate. Founded in 1692 as "Salem," it includes Andalusia, Cornwells Heights, Eddington, Oakford and Trevose. Poquessing Creek marks its line with Northeast Philadelphia, and Neshaminy Creek its eastern edge.
1970s Houses, Poured and Block Walls
Bensalem has the youngest housing of the five townships on this site. The median home was built in 1975, about 30% went up during the 1970s alone, and only about 6% predate 1940 (Census survey). Roughly 42% are detached houses and about 20% are townhouses, so most basements here have poured concrete or concrete block walls rather than old stone.
Newer doesn't mean leak-proof. A 1970s basement has seen about fifty winters of freeze and thaw, and poured walls tend to leak at cracks, tie holes and the seam where wall meets floor. About 62% of homes are owner-occupied, with a median owner value of $364,400 (Census QuickFacts).
What Local Contractors Do in Bensalem, PA
The visiting contractor recommends the fix. Common jobs here:
- Crack repair. Poured walls from the 1970s and 1980s often show vertical shrinkage cracks that an injection can seal from inside.
- Sump pump work. Where a pit already exists, an older pump may need replacing, a check valve or a battery backup.
- Full waterproofing. An interior drain at the footing, carrying water to a sump, is the usual answer when seepage shows along several walls.
- Leak repair. A single wet spot at a utility opening or a window well can often be handled as a smaller job.
- Drainage outside. On flatter lots, downspouts that drop water right at the foundation are worth extending first.

Neshaminy on One Side, Poquessing on the Other
Bensalem sits between two creeks that run to the Delaware River. When Ida's remnants passed on September 2, 2021, the National Weather Service recorded the Neshaminy at Langhorne cresting at 20.84 feet, a major flood stage. On the township's other side, rising Poquessing Creek led to voluntary evacuations along flood-prone State Road.
By early September 2026, the National Weather Service office in Mount Holly had issued a record 147 flood warnings, and the Inquirer named Bensalem's Station Avenue a flooding trouble spot.
- Damp along the base of the wall. A wet strip where wall meets slab after heavy rain usually means water is finding that seam.
- A pump that cycles in dry weather. A sump running days after the rain stops may be pulling in a high water table.
- Water from the floor drain. That signals a sewer backup, not seepage, and calls for a different fix.
For a backup, start with the township. Bensalem's Municipal Building, 2400 Byberry Road, takes questions at 215-633-3600 about who handles sewer problems at your address.
Bensalem, PA Contractor Licenses and Permits
Before Bensalem issues a permit, the contractor has to hold a license with the township; that sits on top of the statewide home improvement registration with the Attorney General. Plumbing adds another step: new plumbing fixtures need approval from the Bucks County Water & Sewer Authority, so a basement bathroom or laundry sink added during the project falls under that rule. Building & Planning can be reached at 215-633-3644. Your contractor confirms which permits the work requires, and any plumbing should go to a licensed plumber.

Questions About Bensalem, PA Basements
My house was built in the 1970s. Isn't it too new to leak?
Not necessarily. Fifty years is long enough for a poured wall to develop shrinkage cracks or for block mortar to pass moisture. A contractor's visit can show whether water enters through a crack, a joint or the floor seam.
Who do I contact when water comes up through a floor drain in Bensalem?
Start with Bensalem Township at 215-633-3600 and ask who handles sewer backups for your street. The city's backwater-valve program stops at the Philadelphia line. A plumber can tell you whether a backwater valve makes sense for your house.
What if a basement bathroom is part of the project?
It adds steps. New plumbing fixtures in Bensalem need approval from the Bucks County Water & Sewer Authority, and that work belongs with a licensed plumber under a permit. Ask the contractor who will handle that part and get it written into the contract.
How much can a contractor ask for before the work starts?
Under Pennsylvania's home improvement law, a job over $5,000 generally can't carry a deposit above one-third of the price, plus any special-order materials, and no payment is due before the contract is signed.
