Warning Signs Your Pittsburgh Sewer Line Needs Repair
Traditional sewer line excavation adds $150–$350 per linear foot in landscaping restoration costs alone - on top of the repair itself. Trenchless costs less in total and leaves your yard, driveway, and landscaping completely untouched.
- Multiple drains backing up at the same time — main sewer line blockage or collapse
- Sewage backing up into basement drains or toilets — active line failure
- Rotten egg smell rising from multiple drains — sewer gas escaping through a break
- Wet or sunken patches appearing in your yard — underground pipe actively leaking

CIPP Lining (Cured-in-Place)
New resin liner created inside the existing pipe and cured into a smooth, seamless surface. 50+ year lifespan. Most corrosion-resistant option. Best for the majority of Pittsburgh homes.
Pipe Bursting
The old pipe is fractured outward while new pipe is simultaneously pulled through. Best when you need to upsize the line for higher flow capacity. No loss of pipe diameter.
Slip Lining
A new pipe slipped inside the existing line with gaps filled by strong grout. Used for specific pipe conditions and sizes where CIPP lining is not the optimal choice.

Homeowner Help Center
What is trenchless sewer repair?
Trenchless sewer repair is a way to repair or replace a damaged underground sewer line without digging one long trench across the yard. Instead, plumbers use small access points and specialized equipment to restore the pipe from inside the line. Depending on the condition of the pipe, the repair may involve pipe lining, pipe bursting, hydro jetting, or another sewer repair method. WJ McNabb Plumbing uses trenchless repair to help Pittsburgh homeowners fix serious sewer problems while protecting lawns, sidewalks, driveways, and landscaping as much as possible.
How much does trenchless sewer repair cost in Pittsburgh?
Trenchless sewer repair cost depends on the length of the damaged line, pipe depth, access points, pipe material, repair method, and whether the sewer line needs cleaning or camera inspection first. A short section of pipe lining is very different from replacing a longer or badly collapsed line. WJ McNabb Plumbing provides upfront pricing after inspecting the problem, so you know whether trenchless repair is a good fit and what the job will involve before work begins.
Is trenchless sewer repair better than digging up the yard?
Trenchless sewer repair can be a better choice when the damaged pipe can be repaired or replaced from small access points instead of a full open trench. It can reduce damage to grass, patios, sidewalks, driveways, retaining walls, and landscaping. It can also shorten the mess and restoration work after the repair. Traditional digging may still be needed for collapsed pipes, poor access, certain pipe conditions, or spot repairs. WJ McNabb Plumbing helps homeowners choose the method that solves the sewer problem with the least unnecessary disruption.
What is the difference between pipe lining and pipe bursting?
Pipe lining creates a new pipe inside the existing sewer line. It is often used when the old pipe still has enough shape to support the liner. Pipe bursting breaks the old pipe apart while pulling a new pipe into its place, which can be useful when the existing line is too damaged for lining but the path can still be followed. WJ McNabb Plumbing checks the pipe with the right diagnostic steps first, because the best method depends on the actual condition of the sewer line.
Can trenchless sewer repair fix tree root damage?
Yes, trenchless sewer repair can often help with sewer lines damaged by tree roots, but the right solution depends on how badly the pipe is cracked, separated, or collapsed. Roots usually enter through small openings in older sewer lines, then grow and catch waste until the line backs up. Cleaning the roots may provide temporary relief, but the openings often remain. WJ McNabb Plumbing can clear the line, inspect the damage, and recommend whether trenchless repair can seal or replace the damaged section.
Will trenchless sewer repair work on old clay or cast iron sewer lines?
Often, yes. Many Pittsburgh homes have older clay, cast iron, or aging sewer lines, and trenchless methods may work well when the pipe path is still usable. The key is the condition of the existing line. A cracked or root-damaged pipe may be a good candidate, while a fully collapsed or severely misaligned pipe may need another approach. WJ McNabb Plumbing evaluates the pipe before recommending trenchless repair, so the method matches the home and the line.
How long does trenchless sewer repair take?
Many trenchless sewer repairs can be completed faster than traditional excavation because there is less digging, less backfilling, and less property restoration. The timeline depends on the repair method, pipe length, access, cleaning needs, and how damaged the sewer line is. WJ McNabb Plumbing plans the job around getting the sewer line working again while limiting disruption to the home, yard, and daily routine.
Do I need a camera inspection before trenchless sewer repair?
A camera inspection is usually one of the most important steps before trenchless sewer repair. It helps identify roots, cracks, bellies, separations, blockages, pipe material, and collapsed sections. Without seeing inside the line, it is easy to recommend the wrong repair method. WJ McNabb Plumbing uses the inspection process to make sure trenchless repair is appropriate and to explain what is actually happening inside the sewer line.
