Yes. Whenever site conditions allow, we use trenchless methods to repair or replace sewer lines with minimal digging. Trenchless work protects your landscaping, driveway, and hardscape while restoring your sewer line — often faster and with less disruption than traditional excavation.
Cost depends on the length and depth of the line, the type of damage, access to the pipe, and whether a repair or full replacement is needed. Because every property is different, we provide a free, upfront estimate after diagnosing the issue — so you know the price before any work begins.
In most cases, the property owner is responsible for the sewer lateral that runs from the home to the city’s main line, while the municipality maintains the main itself. We can inspect your line, identify exactly where the problem is, and explain your options.
