scope of work

What do you need done?

the guide

Start outside

Clean gutters, extend downspouts, and grade soil away from the house. Many wet basements improve dramatically before any interior system is installed.

What affects the price

Linear footage of drainage, the number of sump pumps, wall repairs, and whether the basement is finished.

Structural or not

Hairline vertical cracks in poured walls are common. Horizontal cracks, bowing block walls and stair-step cracks deserve an engineer’s assessment.

Rules and paperwork in Pennsylvania

  • Pennsylvania’s Home Improvement Consumer Protection Act requires most contractors who perform home improvements to register with the Attorney General’s office and to give you a written contract for any job over $500. The registration number belongs on the estimate and the contract — ask for it.
  • Building permits in Pennsylvania are issued under the Uniform Construction Code by each municipality or the inspection agency it appoints, so the local building or codes office decides what needs a permit and an inspection.
  • Much of southeastern Pennsylvania is in EPA’s highest radon potential zone, and elevated levels have been found in every county. Test before finishing or sealing below-grade space; Pennsylvania certifies radon testers and mitigators through the Department of Environmental Protection.

Rules change — confirm current requirements with the agency and with your municipality.

Questions to ask before you hire

  1. What is causing the water, and how do you know?
  2. Does the system have a battery backup?
  3. Is the warranty transferable to a buyer?
  4. What is your Pennsylvania Home Improvement Contractor registration number?

Frequently asked questions

Is radon common in my town?

Much of southeastern Pennsylvania is in EPA’s highest radon potential zone, and elevated levels have been found in every county. Testing is inexpensive and the only way to know.

Will waterproof paint solve it?

Coatings do not stop water under pressure. Drainage does.

Does homeowners insurance cover a wet basement?

Groundwater seepage is typically excluded; sump failure may be covered with an added endorsement.
