Why Drainage Is the Foundation's Biggest Enemy
Over 90% of foundation problems in the Chattanooga area trace back to water — either surface water running toward the foundation, hydrostatic pressure from saturated soil, or water intrusion through the foundation wall itself. Fixing the structure without fixing the drainage means the problem will return.
Drainage Solutions We Install
Exterior French drains intercept surface and subsurface water before it reaches the foundation. Interior perimeter drain systems (with sump pump) manage water that enters through the foundation wall. Downspout extensions and grading corrections redirect roof runoff away from the structure. Window well drains prevent below-grade window flooding. We design the right combination for each property's specific conditions.
Drainage Solution Cost in Chattanooga
A standard exterior French drain installation runs $1,500–$3,500 for a typical residential perimeter. Interior drain systems with sump pump run $3,000–$6,000. Comprehensive systems addressing multiple water sources run $5,000–$8,000. We provide a detailed written proposal after the site assessment.
