What affects the cost of Sewer Line Repair & Replacement
Frequently asked questions
How do I know if my sewer line needs repair or replacement?
Common signs include multiple clogged drains, sewage odors, gurgling toilets, lush patches in your yard, or sudden increases in your water bill. A professional inspection can confirm the issue.
What is trenchless sewer repair?
Trenchless repair methods, like pipe bursting or CIPP lining, allow us to fix or replace your sewer line with minimal digging, often requiring only one or two access points. This reduces disruption to your property.
How long does a sewer line repair or replacement typically take?
The duration varies depending on the method and complexity. Trenchless repairs can often be completed in 1-3 days, while traditional excavation and replacement might take 3-7 days.
Will my yard be damaged during the process?
With trenchless methods, yard disruption is minimal. For traditional excavation, we will need to dig a trench, but our team takes care to minimize damage and restore the site as much as possible after the work is done.
