Find the Break Before Planning the Tunnel

Fast Plumbing uses sewer camera inspections and locating equipment to visually identify and locate breaks and damaged piping beneath the foundation. These findings help determine where access is needed and the extent of tunneling required for the repair. The proposed scope depends on the inspection findings and conditions at your property.

One Point of Contact, Oversight at Every Step

Fast Plumbing manages your under-slab sewer replacement project. We hire and direct the tunneling subcontractor and oversee the quality of their work every step of the way, coordinating the excavation with the plumbing work.

Engineering Review Before Backfill

Before backfilling begins, Fast Plumbing hires an engineer to evaluate the structure. City inspections take place along the way. The written project scope should explain excavation, plumbing replacement, inspection, backfill, and restoration responsibilities.

Assistance With Insurance Claims

When an insurance claim is involved, Fast Plumbing can provide camera inspection findings and repair documentation and coordinate with your insurance company as needed. Coverage and claim payments are determined by your insurer under the terms of your policy.

Is Tunneling Right for Every Property?

No. Exterior tunneling can provide access beneath a slab rather than through finished floors, but suitability depends on pipe location, access, soil, structural conditions, and the repair scope. Not every project can avoid interior excavation.

How Much Will It Cost, and How Long Will It Take?

The price and schedule depend on the inspection findings, access, extent of replacement, excavation, inspections, and restoration scope. Call Fast Plumbing to discuss an evaluation and a project-specific proposal. For other sewer problems, see our sewer line repair page.
