Permanent Sewer Line Replacement
Full sewer line replacement from cast iron to Schedule 40 PVC.
A failing sewer line can cause extensive damage to your property. If you notice any of these common warning signs, contact us immediately for a professional inspection.
Sewer Line Replacement — What Every Homeowner Should Know
When sewage backs up into your house or your yard stays soggy with foul-smelling water, you're looking at a collapsed or severely damaged main sewer line. This isn't something you can snake or patch your way out of — the pipe that carries waste from your home to the street has failed, and it needs to be dug up and replaced. Blackmon Plumbing handles full sewer line replacement throughout Greater Houston, swapping out failing cast iron and clay pipes for durable Schedule 40 PVC that'll outlast the house.
You'll know you need a complete line replacement when multiple drains back up at once, sewage bubbles up in your yard, or a camera inspection shows the pipe has collapsed or separated at the joints. In older Houston neighborhoods, we see a lot of cast iron lines from the 1960s and 70s that have finally rusted through, plus clay pipes that tree roots have completely destroyed. Sometimes the city will red-tag your connection during a routine inspection, giving you a deadline to replace the line before they shut off service.
We handle the entire job from permits to final inspection — excavation, tunneling under driveways when needed, proper pipe installation, backfill, and yard restoration. Our trucks carry the PVC pipe and fittings to complete most replacements without delays, and as a Texas licensed master plumber (MPL-38162), we pull permits and coordinate inspections so the work meets code. You get flat-rate pricing approved before we break ground, not hourly billing that climbs while we're digging.
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
We send an experienced crew equipped with specialized excavation tools and the pipe fittings needed to get the job done right. One coordinated project from start to city approval.
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. Our specialized tunneling equipment and experienced plumbers preserve 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.
