Frequently Asked Questions

What is the trenchless sewer repair process like?

The entire trenchless repair process is non-invasive and typically completed in one day. It involves three main steps:

  1. Inspection and Cleaning: The line is inspected with a camera to confirm the damage. Then, the pipe is cleaned, often using a hydro jetter, to remove all debris, scale, and root mass.

  2. Liner Installation: A flexible tube, saturated with a specialized epoxy resin, is inserted into the pipe through an existing access point. It's inflated to press the resin tightly against the old pipe walls.

  3. Curing: The resin is hardened (cured), creating a seamless, structural Cured-In-Place Pipe (CIPP) liner inside the old pipe.

Will you have to dig up my yard, driveway, or patio?

The trenchless method is a "No-Dig" solution designed to avoid major excavation. The process is usually performed through an existing sewer access point, such as a cleanout or manhole. This approach preserves your landscaping, driveway, and any hardscaping, minimizing disruption and avoiding expensive restoration costs. However if no access point exists then a small excavation may be necessary in order to perform the repairs.

What is Cured-In-Place Pipe (CIPP) lining?

Cured-In-Place Pipe (CIPP) lining is a structural product that creates a brand-new, permanent pipe right inside your existing damaged sewer line. Think of it as installing a seamless pipe-within-a-pipe.

It begins as a flexible, felt tube saturated with a powerful epoxy resin. This tube is inserted into the old sewer line, inflated to match the shape of the existing pipe, and then cured (hardened). Once cured, the CIPP liner is a joint-free, rock-hard structural component that seals all cracks and prevents root growth, designed to give your sewer system an extended lifespan of 50 years or more.

My pipe has cracks and roots; can trenchless repair fix that?

Yes, trenchless repair is highly effective for pipes with cracks and root intrusion, assuming the pipe is structurally sound enough to host the new liner. The process begins with a thorough cleaning of the line, often with a powerful hydro jetter, to clear all roots and debris. The new CIPP liner is then installed. Once cured, the seamless lining completely seals all existing cracks and eliminates the joints, which are the main entry points for roots, preventing future intrusion.

Can trenchless repair fix a pipe that is collapsed or severely sagging (bellied)?

No. The trenchless lining method requires the existing pipe to be mostly intact to host the new liner. If the pipe is fully collapsed, the liner cannot be pulled through and installed correctly. If the pipe has a severe sag or "belly," the standing water and solid waste will prevent proper adhesion of the liner, and the issue of improper flow grade can only be fixed by a full replacement using traditional excavation.

When is a trenchless repair better than a full replacement?

Trenchless repair is the superior choice when your sewer line has structural defects (like cracks, joint leaks, or minor root intrusion) but is still properly graded and not fully collapsed. It delivers a permanent, long-term fix with significantly less impact than digging. Here are the key factors when choosing trenchless repair over a full replacement:

  • Property Disruption:

    • Trenchless Repair: Requires minimal to no digging and preserves your existing yard, driveway, and landscaping.

    • Full Replacement: Requires two access pits (pipe bursting) or digging the entire length of the pipe (traditional excavation).

  • Project Time:

    • Trenchless Repair: Fast, usually completed and ready for use in a couple of days.

    • Full Replacement: Slower, often taking around a week due to the time required for excavation, pipe laying, backfilling, and site restoration.

  • Cost Efficiency:

    • Trenchless Repair: More cost-effective overall by eliminating the significant expenses of restoring concrete, asphalt, or extensive landscaping.

    • Full Replacement: The cost of surface restoration is often added to the final bill, making the total project price much higher.

  • Type of Damage:

    • Trenchless Repair is best for: Cracks, failed joints, tree root damage, and minor corrosion.

    • Full Replacement is required for: Fully collapsed sections, or severe pipe sags (bellies) that require the line's grade to be corrected.

In summary, if your pipe's flow grade is good, trenchless repair is the fastest, least disruptive, and most cost-effective solution.

Does the new liner make my pipe smaller and cause clogs?

The new liner does slightly reduce the overall internal diameter of the pipe by a small amount (typically about 1/8 to 1/4 inch). However, this does not negatively affect the flow or increase the risk of clogs. Because the new CIPP lining is seamless and has a smooth interior surface, wastewater moves through the pipe more efficiently than it did in the old, rough, or damaged line.
