FAQs
What exactly is trenchless main line repair and how does it work?
Trenchless repair is a no-dig (or minimal-dig) method of fixing or replacing your home’s main sewer line without excavating a long trench through your yard. We typically use one of two techniques: 1. CIPP (Cured-in-Place Pipe) Lining – A flexible, resin-saturated liner is inverted or pulled through the damaged pipe, then cured with hot water, steam, or UV light to create a seamless, structural “pipe within a pipe.” 2. Pipe Bursting – A bursting head fractures the old line outward while simultaneously pulling a new HDPE pipe into the same path. Both methods require only one or two small access pits, restore full flow capacity, and are rated to last 50+ years.
How can I tell if my McMinnville property needs a main line repair?
Common warning signs include repeated drain clogs throughout the house, gurgling noises in toilets, sewage odors indoors or in the yard, wet or sunken patches of lawn even in dry weather, and wastewater backing up in tubs or floor drains. Because McMinnville’s clay soils and older homes often have original clay or concrete pipes, root intrusion and pipe collapse are prevalent. A video camera inspection will confirm the exact condition of the line and whether trenchless repair is appropriate.
Will trenchless repair disturb my landscaping, driveway, or mature trees?
One of the biggest advantages is minimal surface disruption. We only need an entry and an exit pit—usually about 3–4 ft² each—near your home and at the city connection or clean-out. Your lawn, garden beds, concrete patio, and trees stay intact because we do not dig an open trench the entire length of the pipe. After the job, we backfill the pits and restore the small areas we touched, saving you thousands in landscape and hardscape repairs.
How long does a trenchless main line replacement take compared with traditional excavation?
For most McMinnville residences, the trenchless process—inspection, cleaning, lining or bursting, curing, and final camera verification—can be completed in a single day. Even complex jobs rarely exceed two days. Conventional dig-and-replace projects often take 3–5 days, sometimes longer if permits, traffic control, or utility conflicts arise. Less time means less inconvenience, fewer days without water service, and lower labor costs.
Is trenchless repair approved for McMinnville’s existing clay and concrete sewer lines, and is it safe?
Yes. The City of McMinnville Building & Planning Department recognizes both CIPP lining and pipe bursting as accepted rehabilitation methods, provided all work complies with Oregon Plumbing Specialty Code. Our technicians pull permits, schedule inspections, call in utility locates, and furnish post-repair videos to the city. The new liner or HDPE pipe is chemical-resistant, root-proof, and has a design life of 50 years or more, making it safer and more reliable than the original clay, concrete, or Orangeburg pipe it replaces.
How much does trenchless main line repair cost, and do you offer warranties?
Pricing depends on pipe diameter, depth, length, and site access, but most McMinnville residential projects run $85–$150 per linear foot, all-inclusive. Because you avoid large excavation, you also save on landscape and driveway restoration. We provide written estimates after a free camera inspection, offer straightforward financing options, and back our workmanship with a 10-year labor warranty. The pipe manufacturer’s material warranty is typically 50 years, giving you long-term peace of mind.
