FAQs
What is trenchless pipe replacement, and how is it different from traditional excavation?
Trenchless pipe replacement is a modern technique that installs a new main sewer or water line without digging an open trench the entire length of the pipe. Instead, technicians create one or two small access points and use specialized equipment to pull or push a new pipe into place, bursting or lining the old pipe as they go. Unlike traditional excavation, trenchless methods avoid large trenches, reduce property disruption, shorten project time, and often lower overall restoration costs.
Which main line problems can trenchless technology solve?
Trenchless replacement works for most problems found in Harriman’s older and newer sewer or water mains, including root intrusion, severe corrosion, offset or collapsed sections, frequent blockages, and pipes damaged by ground movement. As long as the existing line follows a relatively straight path and there is sufficient access on both ends, trenchless techniques can typically rehabilitate or fully replace clay, cast-iron, PVC, Orangeburg, or concrete lines.
How long does a trenchless sewer line replacement usually take in Harriman?
Most residential trenchless replacements are completed in a single day. The first few hours are spent setting up equipment, inspecting the line with a camera, and preparing the entry and exit pits. The actual pipe bursting or lining often takes less than an hour. After installation, we perform a final camera inspection and backfill the access points. Larger or more complex projects—such as long runs, multiple bends, or limited access—may require up to two days, but this is still far faster than traditional dig-and-replace methods.
Will trenchless pipe replacement damage my yard, landscaping, or driveway?
Because trenchless technology eliminates the need to dig a continuous trench, surface disruption is minimal. We create small access pits—typically 3–4 feet square—at either end of the pipe run. Your lawn, flower beds, patios, and driveways remain largely untouched, and any disturbed area is restored once the new line is in place. Homeowners in Harriman appreciate that they avoid the widespread turf removal, tree loss, and concrete demolition that often accompany conventional digging.
How much does trenchless main line replacement cost in Harriman, and what affects the price?
Prices generally range from $90 to $180 per linear foot for most Harriman residences, but the exact cost depends on several factors: length and diameter of the pipe, depth below ground, number of bends or connections, need for clean-outs, type of replacement method (pipe bursting vs. cured-in-place lining), soil conditions, and local permit fees. While the upfront price can be comparable to or slightly higher than traditional excavation, homeowners typically save on landscape restoration, driveway repairs, and project time, making trenchless the more economical choice overall.
Is trenchless pipe replacement a long-term solution, and what kind of warranty do you offer?
Yes. We install high-density polyethylene (HDPE) or epoxy-lined pipes rated for 50+ years of service life, resistant to roots, corrosion, and joint failure. After installation, we camera-inspect the line to verify proper placement and flow. Our standard warranty in Harriman covers materials and workmanship for 10 years, and extended warranty options up to 25 years are available. With proper use and routine maintenance, your new trenchless main line should last as long as—or longer than—any traditionally installed pipe.
