When the main sewer line fails, you usually find out all at once: several drains back up together, the yard smells, or wastewater rises in the lowest fixture in the house. It is one of the most disruptive plumbing problems a McKinney homeowner can face, and it is almost never a quick guess — it takes a camera to see what is really going on underground.
Our soil and our trees make sewer lines a recurring issue here. Blackland Prairie clay shifts with every wet-dry swing, and over years that movement cracks pipe joints and creates low spots (bellies) where waste collects. Roots from mature trees chase the moisture and grow inside the line. Homes near the historic downtown square may still have original clay tile or cast-iron sewers that have simply reached the end of their life, while newer subdivisions can suffer settling as the ground under fresh construction adjusts.
We start every sewer job with a camera so you are paying to fix what is actually wrong — and where trenchless methods fit, we repair the line without digging up your whole yard.
Signs of a sewer line problem
- Multiple drains backing up at the same time
- Sewage smell inside the house or out in the yard
- Gurgling toilets when you run a sink or the washer
- Wastewater rising in a tub or floor drain
- Patches of extra-green, soggy, or sunken lawn over the line
- Slow drains throughout the house, not just one fixture
- Repeated main-line clogs after cabling
How we handle it
- 1
Camera inspection first
We run a sewer camera through the line to see the exact problem and its distance from the cleanout — roots, a crack, a belly, a separated joint, or a collapse.
- 2
Locate and confirm the fault
We mark the spot above ground and measure depth, so any dig is targeted and we know whether a trenchless method will work.
- 3
Present repair options in writing
You get clear choices — a spot repair, trenchless lining or pipe bursting, or a full replacement — with the trade-offs and costs spelled out.
- 4
Repair and re-camera
We complete the work, restore the area, and run the camera again to confirm the line is clear, sealed, and flowing correctly.
Trenchless vs. traditional replacement
Not every sewer repair means an open trench across the yard. Where the existing pipe allows it, trenchless methods fix the line through small access points, saving your landscaping, driveway, and patio.
Trenchless options
- Pipe lining (CIPP): a resin-saturated liner is cured inside the old pipe, creating a new seamless pipe within it — good for cracks and root intrusion
- Pipe bursting: a new pipe is pulled through the old one while breaking it apart — good for collapsed or badly bellied lines
- Both need only entry and exit pits instead of a full trench
When traditional dig is the right call
A fully collapsed line, a severe belly that needs re-grading, or a run under obstacles sometimes still requires excavation. When it does, we keep the trench as narrow as the job allows and restore the area properly.
Roots and clay: the North Texas pattern
The most common sewer failure we see follows the same script: expansive clay shifts, a joint opens a hair, roots find the water and grow in, waste snags on the roots, and the line backs up. Cabling clears it for a while, but the roots return. A camera tells us whether the pipe is sound enough to keep clearing or worn enough to justify lining or replacement.
Why choose us for sewer work
Sewer replacement is a big-ticket repair, and you deserve to see the evidence before you spend. We camera first, show you the footage, and never sell a replacement when a targeted repair will do. Work is performed under our Texas Responsible Master Plumber, licensed and insured, with a written warranty on the job.
Why McKinney homeowners choose us for sewer lines
- Every sewer job starts with a camera pushed down the line, so you watch the crack, belly, or root intrusion on screen before spending a dollar.
- Where the pipe allows it, trenchless lining or pipe bursting fixes the line through small pits and spares your yard, driveway, and patio.
- We re-camera after the repair to confirm the line is sealed and flowing correctly, not just cleared enough to last the week.
- Fifteen-plus years under our Texas Responsible Master Plumber means we read Collin County clay-and-root sewer failures accurately the first time.
- We never sell a full replacement when a targeted repair will hold, and every job comes with upfront pricing and a written warranty.
What affects the price
Sewer work spans a wide range depending on length, depth, and method — the DFW benchmarks below are context, and the camera inspection sets the real scope.
- Length of line affected and how deep it is buried
- Spot repair versus lining, bursting, or full replacement
- Trenchless feasibility versus open excavation
- Pipe material and age (clay tile, cast iron, PVC)
- Obstacles above the line — driveways, patios, mature trees
- Permits, city inspection, and traffic or right-of-way factors
- Restoration of landscaping or hardscape afterward
| Service | Typical DFW range* |
|---|---|
| Sewer repair / replacement | $3,000–$15,000+ |
| Drain cleaning (main line) | $150–$400 |
