Start with a timeline, not a coating
Marietta is in Cobb County. For a property in or around the city, the useful local detail is the actual building and lot, not a citywide assumption about flooding. Record whether moisture begins during rain, hours later or in dry weather. A leak below a pipe opening suggests a different investigation from water appearing across a wall-floor joint. Dry-weather moisture also warrants consideration of plumbing or condensation before exterior excavation is proposed.
Keep localized repairs and perimeter drainage distinct
A defined opening may be suitable for a targeted repair after its condition and source are understood. Repeated seepage at multiple points can require a wider collection and discharge plan. Ask what the recommendation addresses, what it leaves unchanged and how the contractor will verify the suspected entry path. Painting over a stain can hide evidence without explaining the source; photograph it before cleaning or refinishing.
Decide what access you can realistically provide
Finished basement walls, shelving and floor coverings may conceal the first wet area. Outside, a patio, porch or driveway can complicate access to the foundation. Describe these obstacles during the initial conversation. Before agreeing to work, ask what needs to be moved or opened, who handles finish restoration and whether the proposed scope depends on inspecting a currently concealed surface.
Treat movement as a separate question
A leaking crack is not automatically a structural failure. However, visible displacement, bowing or changing crack width should be assessed by an appropriately qualified structural professional rather than treated solely as a waterproofing detail. For a Marietta evaluation, gather prior repair information and photographs taken safely over time. Call with the property location to confirm service availability and discuss the appropriate next step before scheduling.
