We Fix the Cause, Not the Symptom

Most sewer problems do not start where they show up, and fixing the surface issue rarely solves anything long term. At Kenco Plumbing & Drains, we use sewer camera inspections to understand what is happening inside your line, whether it is root intrusion, pipe damage, or buildup that continues to return over time. From there, we recommend a solution based on the actual condition of your system, not a guess. That may involve a targeted repair or a full sewer line replacement depending on what we find. Every job is handled by our licensed and insured professionals following proper standards and local code requirements, with a focus on durability, performance, and preventing the same issue from happening again.

FAQs

Answers You Can Rely On

How do I know if the problem is in my sewer line?

If multiple drains in your home begin slowing down at the same time, the issue may be deeper in the sewer line. You might also notice gurgling sounds in pipes, unpleasant odors, or water backing up in lower fixtures like tubs or floor drains. Our team can inspect the system and locate the source of the blockage within the sewer line.

What causes sewer line clogs?

Sewer line blockages often develop when materials like grease, food waste, sanitary products, or so-called “flushable” wipes collect inside the pipe over time. These materials can build up along the interior of the sewer line and restrict how wastewater moves away from your home.

Can a sewer line be repaired, or does it always need replacement?

Not every sewer line problem requires replacing the entire pipe. In many cases, targeted repair can restore a damaged section or remove a blockage. If the pipe has deteriorated or sustained more extensive damage, replacement may be the better long-term solution.

Why do sewer line problems affect multiple drains at once?

All of the drains in your home eventually connect to the main sewer line. When that pipe becomes blocked or damaged, wastewater from several fixtures may struggle to move through the system. This is why slow drainage or backups often appear in more than one place.
