Separate yard drainage from plumbing
If the issue is an outdoor French drain, catch basin, channel drain, buried downspout line, yard drain pipe, swale edge, or outlet, describe it as yard drainage. Sewer, sink, toilet, and indoor pipe backups need a plumbing channel.
Find the failure point
Common outdoor issues include a clogged yard drain, covered grates, sediment in basins, blocked outlets, crushed pipe, root intrusion, settled trenches, missing cleanouts, or a route that no longer has enough slope.
Document the existing system
Photos of visible grates, basins, cleanouts, outlets, pipe ends, wet areas, recent landscaping, and any known installation records can help a provider decide whether cleaning, repair, rerouting, or replacement should be discussed.
Ask about maintenance access
A repair estimate should explain how the system can be opened, flushed, inspected, or cleaned later so the same blockage does not become a recurring hidden problem.
Check public and utility boundaries
If the repair touches a swale, right-of-way, culvert, public catch basin, driveway edge, or buried utility area, ask what City, utility-marking, license, insurance, or professional review questions apply before work starts.
