Crawl Space Drainage & Sump in Columbia, TN
Interior drain and sump to move standing water out before anything gets sealed.
Where water actually pools under the house, sealing it in is the wrong order of operations. A perimeter drain collects it and a sump pumps it clear of the foundation before the space is lined.
Water usually has an outside cause first: gutters discharging at the foundation, grading that falls toward the house, or a downspout that ends six inches from the wall. Those are the cheap fixes, and a contractor who does not mention them before quoting a drain system is skipping the easy answer.
Typical cost: $2,500 - $8,000 depending on trench length and discharge run
When crawl space drainage is the right call
- Standing water after rain, not just damp soil
- A water line or tide mark on piers or foundation walls
- An existing sump that runs constantly or has failed

Common questions
Do I need drainage before encapsulation?
If water pools under the house, yes. A liner over standing water traps it and hides it.
Where does the sump discharge to?
Away from the foundation, and far enough that it does not circle back. A discharge that ends beside the wall recycles the same water.
