Septic System Repairs & Excavation
Don't let big corporate plumbing franchises force you into a $30,000 full-system replacement when a targeted, precision repair is all you need. We repair broken lines, failed D-boxes, and crushed pipes quickly.
Precision Diagnosis & Targeted Excavation
Most septic failures are localized: a vehicle drove over a shallow PVC header line, tree roots broke into a distribution box, or an inlet baffle fell into the tank. You don't always need to tear up your entire property to fix it.
Knights Construction and Supplies uses compact, rubber-tracked mini excavators with smooth-edge buckets. We locate the exact break point, trench cleanly down to the failure without damaging surrounding mature trees or landscaping, make the repair to Chatham County Health standards, and backfill with proper granular bedding.
Distribution Box (D-Box) Replacement
When an old concrete D-box crumbles or tips out of level, wastewater floods one trench while starving others. We set new level plastic or polymer D-boxes with speed levelers.
Crushed & Root-Damaged Line Repair
Excavating and splicing crushed SDR-35 or schedule 40 transfer pipes between the tank and drain field. Heavy-duty root barriers installed.
Drain Field Trench Rejuvenation
Clearing bio-mat clogging, replacing compacted gravel aggregate, or installing auxiliary lateral runs to restore natural absorption in dense Piedmont clay.
Septic Tank Riser & Lid Upgrades
Bring buried inspection ports and clean-outs up to ground level. Never dig up your lawn with a shovel again just to inspect your tank.
