Frequently Asked Questions

It depends on the cause and the size of the basement. Sealing one leaking crack costs far less than a full perimeter drain system. Ask for a written estimate that names the cause of the water, the exact work, and the warranty terms, and compare at least two.

Exterior work stops water at the wall but requires excavation and costs more. Interior drainage manages water that reaches the wall and is usually less disruptive. Many homes are well served by interior drainage plus better grading and downspouts.

Some fixes are DIY-friendly: cleaning gutters, extending downspouts, and regrading soil away from the house. Waterproof paints rarely solve active leaks. If water returns after rain, have the cause diagnosed.

If water collects under the slab or at the footing, a sump system gives it somewhere to go. If you already have one, consider a battery backup, since storms that cause flooding often cause power outages too.

Thin vertical cracks are often shrinkage. Horizontal cracks, stair-step cracks in block walls, cracks wider than about a quarter inch, or walls that lean inward should be looked at by a professional.

Coverage varies widely by policy. Seepage and groundwater are often excluded, and sump backup may need a separate rider. Check your policy or ask your agent.

Your request is shared with a local waterproofing contractor serving your area, who will contact you to schedule an inspection. See the disclosure at the bottom of every page.
