Start with the condition at your address

Basement waterproofing starts by identifying the water source. Rainwater, groundwater, plumbing leaks and condensation can need different responses. An inspection should trace the entry path before recommending surface drainage, crack treatment, interior collection and pumping, or exterior water-control work.

Share your city, the part of the home affected, when the issue appears, and any previous inspection or repair records. Confirm the contractor and appointment terms before scheduling.
