FAQs
What is trenchless main line repair, and how does it work in Dandridge?
Trenchless main line repair is a modern plumbing technique that fixes or replaces damaged sewer and water lines without extensive digging. In Dandridge, we typically use pipe bursting or pipe lining (cured-in-place pipe, CIPP). Pipe bursting pulls a new HDPE pipe through the old line while breaking the existing pipe outward. Pipe lining inserts a resin-soaked liner into the pipe, which hardens to create a smooth, joint-free interior. Both methods require only small access points at either end of the line, preserving your yard, driveway, and landscaping.
How do I know if my home’s main sewer line qualifies for trenchless repair?
Most clay, cast-iron, or PVC lines from 2" to 12" in diameter can be repaired trenchlessly as long as the pipe path is mostly straight and there’s space to set up entry and exit pits. We perform a video camera inspection first to locate breaks, root intrusion, or bellies. If the line has collapsed completely or has severe misalignments, a short open-cut section may be required, but the majority of the run can still be trenchless. Our technician will give you a precise assessment after the inspection.
Is trenchless repair more expensive than traditional digging methods?
Per linear foot, trenchless repair can cost slightly more than conventional excavation. However, it frequently saves money overall because you avoid landscape restoration, driveway or sidewalk replacement, and days of labor. In Dandridge, homeowners often find the total project cost comparable—or even lower—when factoring in the avoided collateral damage. Additionally, the new pipe or liner typically comes with a 50-year warranty, reducing long-term maintenance costs.
How long does a trenchless main line job take from start to finish?
Most residential trenchless repairs in Dandridge are completed in one day. The process generally involves a 1- to 2-hour camera inspection and hydro-jet cleaning, followed by 2-4 hours for lining or bursting, and a final camera confirmation. Because there’s minimal excavation and no need to regrade soil, you regain full use of your plumbing system the same day, and your property is left virtually untouched.
Will trenchless repair disrupt my landscaping or driveway?
One of the biggest advantages of trenchless technology is its minimal impact. We create two small access pits—usually 3'×3'—at the start and end points of the line. This means trees, shrubs, patios, and driveways remain intact. If the existing clean-out is usable, we sometimes only need one pit. Afterward, we backfill the holes and restore the surface, leaving your yard looking nearly the same as before the project began.
Does Dandridge, TN require permits for trenchless sewer work, and do you handle that?
Yes. Jefferson County and the Town of Dandridge require plumbing permits and utility locate tickets for any main line replacement or repair, including trenchless methods. Our team handles all permitting, inspections, and Tennessee One-Call utility marking on your behalf. We coordinate with local inspectors to ensure the new line meets state and local code, so you don’t have to worry about paperwork or compliance issues.
