Checklist

- Keep water away from foundations as locally advised.
- Plan overflow for large storms.
- Choose plants suited to local conditions.

Common homeowner questions
What evidence separates routine dampness from a drainage problem in rain garden drainage?
Rain gardens can manage certain runoff conditions, but placement, soil infiltration, overflow, maintenance, and distance from structures matter. Homeowners should avoid placing water where it worsens foundation problems. Compare timing, location, photos, rain amount, duration, and whether water appears near foundation walls, crawlspaces, sump discharge, grading, gutters, downspouts, or paved surfaces.
Which photos make rain garden drainage easier for a contractor to diagnose?
Use one wide photo showing rooflines, slope, downspouts, paved areas, and the house wall, then close photos of stains, ponding, erosion, cracks, drains, or discharge points with the date and rain context.
How soon after rain should I document rain garden drainage?
Take notes during the rain if safe, again within a few hours, and once the area dries. That sequence shows whether water is flowing through, pooling briefly, or staying long enough to suggest a grading, gutter, sump, or drainage defect.
What scope details matter before paying for rain garden drainage work?
Ask the contractor to identify the observed cause, proposed water path, materials, discharge location, exclusions, access damage, and how the repair will be checked during the first meaningful rain.
