Start with the source
Note whether water appears after rain, near wall cracks or windows, or where the wall meets the floor. Check whether gutters, downspouts, or the slope of the ground send water toward the house. Condensation and plumbing leaks can also cause dampness. An on-site assessment can help tell these problems apart.
Compare waterproofing options
Options may include extending downspouts, changing the slope of the ground (grading), exterior waterproofing, interior drainage, or a sump pump. Interior drainage collects and carries away water that reaches the system; exterior measures address water outside the basement. Ask where the water will go, what maintenance is needed, and whether any wall or foundation movement needs a separate evaluation.
