Answers to frequently asked trenchless sewer repair questions from Merrimack property owners.
Trenchless sewer repair in Merrimack typically costs $4,000 to $12,000 depending on pipe length, diameter, and damage extent. While the repair itself may cost more than excavation, total project cost is often lower because you avoid landscaping, driveway, and hardscape restoration.
Most trenchless sewer repairs in Merrimack are completed in a single day. CIPP lining cure times range from 2 to 6 hours, and pipe bursting installations are typically done in 4 to 8 hours. Compare that to 3 to 5 days for traditional excavation.
Yes. CIPP liners and burst-in HDPE pipe are rated for 50+ years of service. The seamless liner is actually more resistant to root intrusion than traditional jointed pipe because it has no joints for roots to enter. Scranton Sewer Authority warranties trenchless repairs in Merrimack.
Minimal. CIPP lining typically requires no excavation if a cleanout exists. Pipe bursting requires two small access pits at each end of the repair. Both methods avoid the full-length trench that traditional replacement requires.
Our reputation is built on results. Here is what our customers have to say.
"Had multiple drains backing up at the same time. Turned out to be a collapsed section of our sewer line. They found it with the camera, gave us options including trenchless repair, and had it fixed within two days."
"Our commercial kitchen drains were draining slower and slower. They did a full hydro jetting of the grease lines and cleaned the trap. Everything flows perfectly now. We are setting up quarterly maintenance."
"Had sewer line relining done after a camera inspection revealed multiple cracks. The liner went in smoothly and the crew showed us the before and after camera footage. Night and day difference inside the pipe."
