Slab Leak Repair: How Long Does It Take?
Timeline by Repair Method
Spot repair (break through the slab): The plumbing work itself takes one day. The plumber arrives in the morning, jackhammers through the slab at the marked location, replaces the damaged pipe section, and patches the concrete by end of day. The concrete patch needs 24 to 48 hours to cure before flooring can be installed over it. Flooring replacement takes an additional one to three days depending on the material and whether it needs to be ordered.
Tunneling: Two to three days for the complete plumbing repair. Day one is spent digging the access pit and beginning the tunnel. Day two continues the tunnel to reach the pipe and complete the repair. Day three (if needed) is for backfilling the tunnel, compacting the soil, and restoring the access pit area. Interior disruption is minimal since the work happens outside and beneath the home.
Pipe rerouting: One to two days for the plumbing. The plumber caps the old line and routes the new pipe through walls or attic on the first day. Testing and final connections are completed on the second day. Drywall patching and painting where the new pipe penetrated walls takes an additional one to two days.
Epoxy pipe lining: One day. The liner is inserted and inflated in the morning, and the epoxy cures over several hours. The treated pipe is typically back in service by the next morning. No concrete work, no flooring work, no drywall work.
Full repiping: Three to five days for a typical home. The crew works room by room, routing new PEX through walls and attic, connecting each fixture to the new supply lines, and capping the old under-slab pipes. The home may be without water for portions of each work day. Drywall patching, texture matching, and painting after repiping takes an additional two to four days.
What Can Delay the Timeline
Scheduling backlog. In areas with high slab leak volume (Texas, Arizona, California, Florida), plumbing companies may have a waiting list of one to two weeks during busy seasons. Emergency services are available but cost more. Getting on the schedule is often the longest delay in the entire project.
Insurance coordination. If you file an insurance claim for the water damage, the adjuster may need to inspect the damage before repairs begin. Adjuster availability can add three to ten business days to the timeline. To avoid unnecessary delays, ask the adjuster if they can do a virtual inspection using photos and video you provide, or whether they can authorize emergency mitigation (water shutoff, drying equipment) while scheduling the in-person visit.
Flooring material availability. If the repair required breaking through tile or hardwood flooring, matching the replacement material can take time. Discontinued tile may need to be sourced from specialty suppliers. Custom-stained hardwood may need to be ordered, stained, and finished before installation. Standard materials like carpet and vinyl are usually available within a few days.
Mold remediation. If the detection or repair process reveals mold growth beneath the flooring, mold remediation must be completed before new flooring is installed. Remediation typically takes two to five days for a localized area and must pass a clearance test before the area is closed up.
Foundation stabilization. If the slab leak caused foundation movement, the soil needs 30 to 90 days to dry and stabilize after the plumbing repair before foundation work can begin. This is the longest potential delay in a combined slab leak and foundation repair project, and it cannot be shortened without risking a failed foundation repair.
Emergency Situations
If you have an active slab leak that is causing visible flooding, rapidly rising water bills, or sounds of significant water flow under the floor, most plumbing companies offer same-day or next-day emergency service. Emergency calls typically carry a $100 to $300 surcharge but get you immediate water shutoff and a faster path to detection and repair.
While waiting for the plumber, shut off the water at the main shutoff valve to stop the leak. The water meter should stop moving once the valve is fully closed. This prevents further damage and water waste while you wait for the repair crew.
The plumbing repair takes one to five days depending on the method. The full project including scheduling, repair, and restoration typically takes one to three weeks. Insurance coordination, material sourcing, and mold remediation are the most common causes of timeline extensions.
