A useful drainage inspection follows the water from source to outlet. We look at roof runoff, grading, inlets, cleanouts, pipe routes, discharge points, erosion and moisture evidence so repair decisions are based on the cause rather than the symptom.

Planning for San Bernardino Properties
Local drainage work has to account for intense summer heat, compacted soil, short periods of concentrated rain, irrigation, block walls, finished patios and the elevation changes found toward the northern foothills. A reliable system also needs a discharge point that can be inspected and maintained.
Before digging, the route should be checked for practical access and utilities. Work that affects a public right-of-way, curb, sidewalk or municipal drainage feature may involve additional requirements.

Drainage System Inspection — FAQs
How can I tell if a drain is clogged or poorly designed?
A clog often creates localized backup. A design issue can show up as water bypassing the trench, an outlet that is too high, or persistent ponding even when the pipe is open.
Can pipe be inspected without digging?
Sometimes. Accessible cleanouts or open pipe ends may allow controlled testing or camera inspection, but corrugated pipe, tight bends, roots and collapsed sections can limit access.
Should a French drain carry downspout water?
Not automatically. Solid pipe is usually better for concentrated roof runoff, while the French drain collects subsurface water.
When is the best time for inspection?
Dry-weather inspections are useful, but active or recent rain can reveal ponding marks, wet retaining-wall areas, sediment trails and outlet flow that are otherwise hidden.
