Signs You Need Sewer Repair or Replacement
Sewer problems often start small but can lead to costly damage if left unaddressed. Recognizing the early warning signs can help prevent bigger plumbing issues.
Here are some common indicators that your sewer line may need repair or replacement:
- Slow or gurgling drains. If sinks, tubs, or toilets are draining slowly—or making gurgling noises—there may be a blockage in your sewer line. This is especially concerning when multiple drains in your home are affected, as it often points to a deeper issue in the main sewer line rather than a simple clog. Our team uses advanced drain and sewer camera inspections to pinpoint blockages and assess whether a deep cleaning or a more extensive repair is needed.
- Sewage smells in your home or yard. A strong sewer odor inside your home or in your yard could mean there’s a crack or leak in the sewer line. In Arizona’s dry climate, sewer gas leaks can become noticeable more quickly than in other regions. If you notice persistent foul odors, it’s worth having your sewer line inspected. We perform non-invasive sewer line inspections to locate leaks and assess whether a targeted repair or full pipe replacement is the best solution.

Sewer Services We Offer
Sewer Line Repair
Not all sewer problems require a full replacement. If damage is limited to a small section of the pipe, a targeted repair may be all that's needed. Common issues like small cracks, isolated root intrusion, or minor pipe shifts can often be fixed without replacing the entire sewer line.
We assess the damage using camera inspections to determine if a repair is possible. By fixing the affected area, we help homeowners avoid unnecessary costs while restoring proper drainage.
Sewer Line Replacement
If a sewer line is severely damaged, corroded, or made from outdated materials like clay or cast iron, replacement is often the best long-term solution. Arizona’s hard water and shifting desert soil can cause pipes to deteriorate faster, leading to frequent backups or leaks.
We replace old sewer lines with durable materials designed to withstand local conditions. Our team handles the entire process, from excavation to installation, minimizing disruption to your home or business.
