Homeowner FAQ
French drains, runoff, and yard drainage questions.
General planning information for South Bay property owners. An independent contractor must evaluate the property before recommending a scope or price.
What is a French drain?
It is commonly a gravel-filled trench containing perforated pipe. It can collect water from surrounding soil and direct it to a planned discharge location.
How do I know whether I need a French drain or a surface drain?
That depends on whether the water is moving through soil, running across the surface, arriving from a downspout, or pooling at a low point. A site evaluation can distinguish the source.
Where should drainage water go?
That depends on the property, elevation, available routing, and applicable local rules. A proposed system should include a clear discharge path before installation starts.
What should I photograph before requesting help?
Capture the problem area during or after rain, nearby downspouts, slope changes, existing drains, hardscape edges, and any visible outlet.
Can grading help with yard pooling?
In some cases, regrading or a swale can direct surface water away from a problem area. Whether it is appropriate depends on the lot and how runoff can be managed.
How much does drainage work cost?
Cost depends on access, excavation, materials, distance, depth, water source, and discharge solution. A contractor needs property details before giving a reliable estimate.
Does San Jose Drain Pros perform installations?
No. This site is an independent contractor-introduction service. Providers independently determine availability, licensing, scope, pricing, permits, and workmanship.
How does a contractor introduction work?
Submit a project request with your contact details and drainage issue. We store the request and may use it to facilitate contact with an independent provider.
