Common Sewer Line Service Questions

You should hire a sewer service professional to unclog a main sewer line with tree roots. Tree roots can grow into the main sewer line, and this problem requires a specialized hydro jet, or rooter, that is powerful enough to clear the roots. The tree can also damage the main sewer line, and a professional will need to make repairs or replace the damaged sections. Sewer line replacement costs about $60 to $250 per linear foot.

Sewer line replacement costs often seem high because this is a labor-intensive project that requires excavation, pipe removal, and pipe replacement. It takes a team of experienced, licensed technicians to handle the planning required. Sewer pipe work also requires specialized equipment that can include high-tech inspection cameras, excavators, trenching machines, and relining tools. While costs can vary based on the type of piping you choose, high-quality pipe materials that provide years of safe usage can come at a premium.

A clogged sewer line is not typically covered by homeowner’s insurance, though some sewer line issues are covered. For instance, damage related to a fallen tree is usually covered. Though sewer line replacement is not covered in a standard insurance policy, some companies offer add-ons for this purpose. Read the fine print before spending your own money.

A sewer line should be cleaned at least once every 18 to 22 months. The process takes about 30 minutes or up to 5 hours, depending on the size of the line, how easy it is to access, and how long it’s been since the previous cleaning. If your sewer line hasn’t been cleaned in a couple of years or you don’t even know the last time it’s been cleaned, it’s time to call a pro.

Trenchless sewer replacements are actually a great solution for sewer lines located under concrete. A professional can still sleeve and burst old piping to make room for a new one without having to dig up your slab.
