FAQs
What is trenchless pipe bursting and how does it repair a damaged main line?
Trenchless pipe bursting is a method of replacing a failing sewer or water main without digging an open trench the entire length of the pipe. A bursting head is pulled through the old line, fracturing it outward while simultaneously towing in a new, seamless high-density polyethylene (HDPE) pipe of the same or larger diameter. Once the new pipe is in place, service connections are reinstated, leaving you with a brand-new main line that meets current code and resists root intrusion, corrosion, and leaks.
When is pipe bursting the right solution for my Lenoir City property?
Pipe bursting is ideal when the existing line is severely cracked, collapsed, or undersized, and when the yard, driveway, or landscaping makes open-cut excavation undesirable. In Lenoir City’s clay and loam soils, the technique performs well on vitrified clay, cast iron, Orangeburg, and some PVC lines up to 300 ft in length and 2"–12" in diameter. We verify suitability with a video inspection and locate utilities to ensure the bursting head has a clear path.
How much disruption should I expect compared with traditional trenching?
Only two small access pits—one at each end of the run—are needed. This means: • Minimal damage to lawns, flower beds, patios, and driveways. • Little or no need to remove mature trees or fencing. • Faster site restoration—usually just backfilling and sodding the two pits. Homeowners who choose pipe bursting typically save 80–90 % in landscape repair costs compared with full-length trenching.
How long does a typical trenchless pipe bursting project take, and will my water service be interrupted?
Most residential jobs in Lenoir City are completed in one day. We schedule utility locates first, then: 1) Morning—dig the entry and exit pits. 2) Midday—insert the bursting rod and pull the new pipe. 3) Afternoon—reconnect services, test, and backfill. Water or sewer service is usually offline for 4–6 hours. We coordinate with you beforehand so the outage happens during a convenient window.
What does trenchless pipe bursting cost in Lenoir City and what factors affect the price?
A typical single-family home main line replacement (50–75 ft, 4" pipe) ranges from $3,500 to $6,500. Variables include: • Length and diameter of the pipe • Depth of the existing line • Number of service connections or bends • Soil conditions and presence of rock • Access issues (driveways, retaining walls, etc.) We provide a fixed quote after a camera inspection so you know exactly what to expect—no surprise add-ons.
Are permits and inspections required, and do you offer warranties on the new pipe?
Yes. Lenoir City and Loudon County require a plumbing permit and inspection for main line replacements. We handle the paperwork, coordinate with the city’s building department, and schedule final approval. All of our pipe bursting installations come with a 10-year labor warranty and a 50-year manufacturer’s warranty on the HDPE pipe. If any workmanship-related issue arises within the warranty period, we will repair it at no cost to you.
