The right starting point.
French drains collect water through a subsurface drainage envelope. Trench or channel drains typically collect surface runoff through a grate, often beside pavement. Choose based on the source, flow, location, and outlet instead of using the names interchangeably.
What to review for your property
Subsurface seepage
Include subsurface seepage in your project assessment. Photos and a description of wet-weather conditions help define the questions to answer on site.
Surface runoff
Include surface runoff in your project assessment. Photos and a description of wet-weather conditions help define the questions to answer on site.
Grate placement
Include grate placement in your project assessment. Photos and a description of wet-weather conditions help define the questions to answer on site.
Outlet capacity
Include outlet capacity in your project assessment. Photos and a description of wet-weather conditions help define the questions to answer on site.
Before installation begins
Confirm the water source, utility locations, route, receiving point, and applicable local requirements. Public drains, streets, neighboring properties, and wetlands should never be assumed to be approved outlets. Ask which maintenance access and restoration work are included in the scope.
What determines the cost?
Length and depth are only part of the estimate. Excavation access, existing surfaces, soil conditions, materials, outlet construction, and restoration all change the scope. ValueDrainage confirms pricing for the individual property rather than promising one nationwide price.
Common questions
Is a French drain right for every wet yard?
No. Surface runoff, roof water, and subsurface moisture may need different solutions. A complete assessment determines the collection method and suitable outlet.
Can I request help for a business property?
Yes. Select the business / property manager option and describe access, operating hours, and the affected areas.
How do I find availability near me?
Use our state and city directory or submit your city and ZIP code. Availability is confirmed by property address.
