Common homeowner questions
What evidence separates routine dampness from a drainage problem in drainage contractor bid comparison?
A drainage bid comparison should document the problem being solved, proposed route, outlet location, materials, excavation limits, restoration work, exclusions, maintenance expectations, and what evidence will show the project worked. 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 drainage contractor bid comparison 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 drainage contractor bid comparison?
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 drainage contractor bid comparison 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.
