Sewer Line Replacement — What Every Homeowner Should Know
Signs You Need a Sewer Line Replacement
Multiple slow-running or clogged drains — When several fixtures back up simultaneously, the main sewer line is compromised
Foul sewage odors in your yard or home — Broken pipes leak raw sewage into surrounding soil
Gurgling noises from toilets and drains — Air pockets form when water can't flow through damaged sections
Unusual lush, green patches of grass in your lawn — Sewage acts as fertilizer where pipes leak underground
Waterlogged spots or sinkholes in the yard — Saturated soil indicates major pipe failure beneath
Foundation cracks or shifting — Eroded soil from sewer leaks undermines structural support
Sewage backing up into your tub or shower — Complete blockage forces waste water back through lowest drain points
Our Sewer Line Replacement Process
Sewer Camera Inspection
We begin with a high-definition video camera inspection to accurately locate the source of the problem and assess the overall condition of your sewer line. This eliminates guesswork and prevents unnecessary digging.
Detailed Quote & Permitting
You receive a clear, upfront quote for the full replacement. We handle all required city permits to ensure the project is fully compliant with local codes. No surprise fees or permit delays.
Excavation or Tunneling
Our experienced crew carefully excavates the line using trenching or tunneling methods to minimize disruption to your home, driveway, and landscaping. We bring the right equipment for your specific site conditions.
Old Pipe Removal & New Pipe Installation
We remove the old, damaged pipe and install a brand new, high-quality Schedule 40 PVC sewer line, ensuring the proper grade for optimal flow. Professional installation prevents future settling and blockages.
System Testing & Inspection
The new line is thoroughly tested to confirm it's working flawlessly. We then coordinate with city inspectors to get the work approved. Your replacement meets all municipal standards.
Backfill & Site Cleanup
Once the inspection is passed, we carefully backfill the trench or tunnel and perform a basic restoration of the work area, leaving your property clean. Permanent repair, permanent solution.
Our Sewer Replacement Methods
Conventional Excavation (Trenching)
The most common and effective method for sewer line replacement. We dig a trench to provide full access for removing the old pipe and installing the new one. Complete visibility means accurate diagnosis and proper installation. We see every connection, every joint, every potential problem point. This method delivers the most reliable, long-lasting repair.
Tunneling
When the sewer line runs under driveways, patios, or mature landscaping, we tunnel beneath them. We replace the pipe without destroying surface structures. Specialized tunneling equipment on our mobile warehouse preserves your property investment. We access the damaged pipe while leaving your driveway, patio, and landscaping intact. Both methods use the same high-grade materials and professional installation standards. We carry everything needed for either approach—no second trips for specialty equipment or missing components.
