Most individuals don’t usually give their drain and sewer lines much thought until an issue arises. However, when your underground pipe breaks or fails, the main priority will always be to get the issue fixed as soon as possible. Luckily, Bob Oates Sewer & Rooter offers trenchless sewer repair in Bellevue, WA.

While traditional sewer line replacement has the same goal of restoring damaged pipes back to their optimal functionality, there are key differences between the dig-and-replace method and the trenchless solutions that our team specializes in.

Damage to the Yard

Traditional sewer pipe line repair and replacement services involved extensive excavation. In short, no yard is safe. In most cases, property owners would have to call for landscape restoration services – another expense to think about. Add that to the inconvenience of having your yard or property literally torn up.

Trenchless sewer repair services, on the other hand, still involve digging, but the amount is very minimal – the pipe technicians only need to get to the cleanout and the exit point so they could insert the pipe lining material.

Duration of the Project

How long it will take to replace sewer line depends on the method of pipe restoration that’s being utilized, along with how big the project is. With the dig-and-replace method, the pipe needs to be located, the trenches need to be made, the affected pipe needs to be removed and replaced, and finally, reburied. This process can span anywhere from a few days to weeks.

Trenchless sewer replacements can be done in a much shorter amount of time. It’s not uncommon for trenchless projects to be completed within a day, sometimes in mere hours.


Needless to say, trenchless repair techniques are more cost-efficient than traditional solutions since they require less time and work. In other words, you save on labor costs.

If you feel that you might need to replace sewer line utilizing the trenchless technique, contact Bob Oates Sewer & Rooter to learn more or to arrange a consultation with our team.
