This commercial property in Warren had lived with sewer blockages, backups and downtime for years. The line had already been “fixed” once. That earlier repair turned out to be the problem.

The problem: backups that kept coming back

The building’s main sewer line kept blocking and backing up. Every backup meant downtime for the property, and it had been going on for years.

What caused it: a repair done wrong

Years earlier, another plumbing company had “fixed” this main sewer line. They did it wrong. The property kept getting blockages because the line was never really repaired.

How we fixed it

We excavated 11.5 feet down to the main sewer line.
We uncovered the failed section from the earlier repair.
We rebuilt the main line the right way. No shortcuts and no temporary patches.

The result

The property dealt with backups until we stepped in. With the failed repair dug out and the main line rebuilt, the cause of those backups is gone.

If your building keeps backing up

A building that backs up again and again may not have “just another clog.” It may have a repair that was never done correctly. Another cleaning can clear the line for a while, but it can’t fix a pipe that was repaired wrong.

When cleaning will solve the problem, we tell you that before anyone talks about digging. When the pipe itself has failed, we repair it with our own excavation equipment and crew. See sewer line repair and replacement, excavation and sewer camera inspection.
