FAQs
What is trenchless main line repair and how does it work?
Trenchless main line repair is a family of technologies that fix or replace underground sewer or water lines without digging a long, open trench. Instead, we create one or two small access points to reach the pipe. From there, we insert specialized equipment to either rehabilitate the existing line with a resin-soaked liner (cured-in-place pipe, or CIPP) or install a brand-new pipe by breaking up the old one (pipe bursting). The finished result is a seamless, code-approved pipe that meets or exceeds the life expectancy of new conventional piping—all completed with minimal surface disruption.
Which trenchless techniques do you offer in Oakdale and when are they used?
Our Oakdale crews specialize in two primary methods: 1. Cured-In-Place Pipe (CIPP) Lining – Ideal when the host pipe is still structurally sound but has cracks, small offsets, root intrusion, or corrosion. A felt or fiberglass liner impregnated with epoxy is inverted or pulled into the pipe, inflated, and cured to form a tight, joint-less new pipe inside the old one. 2. Pipe Bursting – Best when the existing line is collapsed, undersized, or made of materials such as Orangeburg or clay that are beyond rehabilitation. A bursting head is pulled through the old pipe, fracturing it outward while simultaneously pulling in a new HDPE pipe of equal or greater diameter. Our technicians perform a camera inspection first to determine which option delivers the longest-lasting and most cost-effective repair for your specific main line issue.
Will trenchless repair damage my landscaping, driveway, or mature trees?
One of the biggest advantages of trenchless technology is its ability to protect your property. Because we only need small entry and exit pits—usually 3-4 ft² each—your lawn, flower beds, hardscaping, and mature trees remain largely untouched. Driveways and sidewalks typically require no demolition. Any displaced sod or pavers around the access pits are carefully removed, set aside, and restored after the repair. In most cases, the area heals within a few weeks and no one can tell a repair was done.
How long does a typical trenchless main line project take from start to finish?
For a single-family home in Oakdale, most jobs are completed in one day: half a day for setup and cleaning the existing line, and half a day for lining or bursting, curing, and final camera inspection. More complex projects involving multiple bends, deeper pipes, or longer runs (over 100 feet) may extend to two days. Either way, trenchless methods are dramatically faster than traditional excavation, which can take several days to a week and require additional time for landscaping and concrete repairs.
What factors affect the cost of trenchless repair versus traditional excavation?
Key cost drivers include: • Pipe length and diameter – Larger or longer runs use more liner material or require more HDPE pipe. • Depth and access – Deeper lines may need bigger entry pits or shoring, although still far less than full trenching. • Pipe condition – Extensive root removal or descaling before lining can add labor. • Number of tie-ins and bends – Each connection to branch lines or multiple 45°/90° elbows adds complexity. • Type of trenchless method – Pipe bursting is generally more expensive than CIPP but may be the only option if the host pipe is fully collapsed. Overall, trenchless repair in Oakdale often ends up 10–30% less expensive than a traditional dig when you factor in landscape restoration, concrete replacement, and additional downtime.
Are permits and inspections required in Oakdale, and do you handle that process?
Yes. The City of Oakdale Building Inspections Division requires a plumbing permit and a final inspection for any main line repair or replacement, including trenchless work. Our team pulls the necessary permits on your behalf, schedules all city inspections, and provides the post-repair video documentation the inspector needs to sign off. We stay on-site for the inspection, handle any questions, and ensure the project is fully code-compliant before we close the access pits and restore your property.
