Sewer Line Repair & Replacement

From trenchless pipe patching to full sewer line excavation, our master plumbers fix underground pipe problems the right way — with upfront pricing and the most economical solution for your home.

WARNING SIGNS

How to Tell If Your Sewer Line Needs Repair

Underground sewer problems don’t always announce themselves right away. Here are the most common signs that something is wrong beneath your yard.

Recurring Drain Backups

If multiple drains in your home back up at the same time — or your main line keeps clogging even after clearing — the problem is likely in your underground sewer pipe.

Soggy or Sunken Yard

Unexplained wet spots, sinkholes, or areas of unusually green grass in your yard can indicate a leaking or broken sewer line underground.

Slow Drains Throughout the House

When every drain in your home is slow — not just one fixture — the issue is usually in the main sewer line, not individual drain pipes.

Sewage Odors

Persistent sewer smells in your yard or near your foundation are a strong indicator that a sewer pipe has cracked, separated at a joint, or collapsed.

Gurgling Drains

Gurgling sounds from toilets, sinks, or tubs when you run water elsewhere in the house can signal a blockage or break in your sewer line causing air pockets.

Foundation Cracks or Shifting

A broken sewer line near your foundation can erode soil and cause settling, leading to cracks in your foundation or uneven floors inside the home.

WHAT WE DO

Underground Sewer & Water Line Services

When your sewer line breaks, collapses, or separates underground, you need a team that can diagnose the problem accurately and present you with the most cost-effective repair. At Southside Plumbing, that’s exactly what we do.

Our master plumbers start every sewer job with a camera inspection to see exactly what’s happening inside your pipe. From there, we’ll walk you through your options — whether that’s a targeted pipe patch, a section of pipe replacement, or a full yard line excavation — and give you upfront pricing before any work begins.

We handle sewer pipes, water lines from the meter to your home, and even water lines bent or damaged by foundation settling. Our goal is always the same: find the most economical solution that solves the problem permanently.

TRENCHLESS REPAIR

Sewer Pipe Patching

Not every sewer problem requires digging up your yard. When the damage is localized — a crack, a joint separation, root intrusion at a single point, or a small hole — pipe patching can repair the problem from the inside without excavation.

We use trenchless technology that places a resin-saturated fiberglass patch inside the pipe at the exact point of failure. The patch is inflated and cured in place, creating a permanent structural repair that restores full flow.

  • Repairs pipes up to 4″ in diameter
  • Fixes cracks, joint separations, root intrusion damage, and small holes
  • No digging — the patch is installed through an existing cleanout or access point
  • We always look for the most economical solution first

FULL LINE REPLACEMENT

Underground Sewer Line Replacement

When damage extends beyond what a patch can fix — multiple failure points, widespread corrosion, a collapsed pipe, or deterioration along the full length of the line — the pipe needs to be replaced. Southside Plumbing excavates and replaces all types of underground residential sewer pipes.

We replace cast iron, clay, and any other sewer pipe material found in residential homes in the south Denver metro area. Many homes built before the 1980s have cast iron pipes that corrode from the inside out over decades. Clay pipes are prone to root intrusion and joint separation. Whatever the material, our master plumbers will develop a replacement plan that minimizes disruption to your home and restores reliable drainage.

  • All pipe types: cast iron, clay, ABS, and more

  • Replaced with modern, long-lasting PVC piping
  • Interior and exterior sewer lines

Sewer Line Replacement: Before, During & After

Here’s what a typical sewer line replacement looks like from start to finish. Every job begins with a camera inspection and ends with a fully restored yard.

Before

Diagnosis & Assessment

Our master plumber runs a sewer camera inspection to locate the exact point of failure — whether it’s a crack, collapse, root intrusion, or pipe separation. We mark the area and present you with your repair options and upfront pricing.

During

Excavation & Replacement

We carefully excavate the failed section, remove the damaged pipe, and install new piping with proper grade and connections. All work is performed to code and inspected. We protect your property throughout the process.

After

Restoration & Verification

Once the new pipe is installed and passes inspection, we backfill the trench and restore your yard. A final camera inspection confirms the new line is clear and flowing properly. Your sewer system is back to full function.

OUR PROCESS

How We Diagnose Your Sewer Problem

We don’t guess. Every sewer repair starts with a thorough inspection so we can give you an accurate diagnosis and the most economical repair plan.

  • 1

    Sewer Camera Inspection – We insert a high-definition camera into your sewer line to visually inspect the condition of the pipe from the inside. This shows us exactly where the damage is, what type of damage it is, and how far it extends.

  • 2

    Locate & Mark – Using the camera’s built-in locator, we pinpoint the exact location and depth of the problem underground. This lets us plan the most targeted, least invasive repair possible.

  • 3

    Review Your Options – We walk you through what we found, show you the camera footage, and present your repair options — from a simple pipe patch to a full line replacement. You get upfront pricing for each option so you can make the best decision for your home and budget.

  • 4

    Execute the Repair – Once you approve, we schedule the work and get it done. After the repair is complete, we run the camera again to verify the line is clear and functioning properly.

Sewer Repair FAQ

Sewer pipe patching at Southside Plumbing starts as low as $4,600 to line pipe up to 4 inches in diameter, or as low as $55/month with financing. Deferred interest plans are available. The final cost depends on the location, depth, and extent of the damage. We always look for the most economical solution and provide clear, upfront pricing before any work begins.

Pipe patching is a trenchless repair method that fixes localized damage inside a sewer pipe without digging up your yard. A resin-saturated fiberglass patch is inserted into the pipe and inflated at the exact point of damage, creating a permanent structural repair from the inside. It works on pipes up to 4 inches in diameter and can repair cracks, joint separations, root intrusion damage, and small holes.

An occasional clog is normal, but recurring clogs can indicate a partial blockage deeper in the line — or even a main sewer issue. If plunging doesn’t fix it, it’s worth having a pro take a look with a camera to catch the real problem before it gets worse.
