Is yard drainage the same as basement waterproofing?
Yard drainage cost depends on the runoff source, discharge route and extent of the work. Yard drainage manages outdoor runoff; basement waterproofing addresses water at or inside the foundation. Correcting roof drainage or surface flow may solve some basement moisture problems, while persistent buried-wall leakage needs a foundation assessment.
Our sister site covers yard drainage methods and costs. Use this site's calculator when the work is inside or at the basement wall.

SIGNS
What outdoor observations help explain a wet basement?
From a safe location, note where roof water lands, where surface water collects and whether nearby paving slopes toward the house. Share photos and the timing of indoor leakage with the inspector.

CAUSES
How can outdoor runoff affect a basement?
Poor surface drainage can concentrate water beside the foundation. That is different from humidity or a plumbing leak inside the building. Establish the source before choosing a trench, pump or wall treatment.

FIXES
Where should you plan yard drainage work?
Discuss roof drainage, grading and a suitable discharge location before buried foundation work. Confirm utility locations and local discharge rules before excavation.

Which costs belong in this scope?
Yard installation costs and methods are maintained on the sister site. A basement wall measurement is not a yard trench design.
