Our Methods

We've refined four core retrofit approaches across 400+ projects in Charleston's Historic District. Each one balances code compliance, preservation, and honest scoping.

Cast-Iron Stack Replacement

Diagnosing, planning, and replacing deteriorating cast-iron drain stacks while minimizing wall damage and maintaining code-compliant venting.

Water Service Upgrade

Lead service line removal, material selection for Charleston's coastal environment, and concealed routing through historic walls.

Integration with Preservation

Working with architects, conservators, and contractors to retrofit modern plumbing without compromising historic fabric or finishes.
