French drain installation
Interior French drain help when water keeps reaching the basement.
Interior French drains and basement drainage systems collect water at the perimeter and move it toward a sump system. Basement Detective checks whether drainage, pump capacity, or another repair is needed.
Drainage warning signs
When a French drain or interior drainage system may be part of the fix.
Drainage plus pump path
Interior drainage is about controlling where water goes.
A French drain can help when water enters at the perimeter, builds pressure at the wall-floor joint, or needs a reliable path to the sump pump. The assessment confirms whether drainage, pump work, crack repair, or broader waterproofing is the right fit.
Drainage questions
Direct answers for homeowners.
What is an interior French drain?
It creates a drainage path that collects perimeter water and directs it toward a sump pump or discharge point.
Will a French drain stop basement water?
It can help when water is entering around the perimeter or wall-floor joint. If cracks, grading, sump capacity, or another path is involved, those may also need attention.
Can an interior French drain help prevent basement mold?
It can help when mold risk is driven by recurring water intrusion that the drain collects and routes away. Affected material still needs proper assessment and cleanup.
Do I need a French drain or a sump pump?
Often they work together. Drainage collects water, and the sump pump moves it out. The inspection should identify whether one or both are needed.
