Sewer Line Repair
Backup? Slow drains? Sewage smell? We scope it with a camera, explain what's wrong, and fix it without tearing up the whole yard.
Call 412-265-5479Signs You Have a Sewer Line Problem
Sewer problems do not fix themselves. The longer you wait, the worse it gets. If you notice any of these warning signs, call us for a camera inspection.
Everything’s slow at once
HighSink drags, tub drags, toilet flushes weakly — all in the same hour. When multiple fixtures slow simultaneously, the issue is downstream of all of them, which means the main line.
That smell outside near the foundation
HighA distinct sewer smell coming from a yard corner, a cleanout, or along the foundation often means the lateral line has cracked or a joint has opened up. The smell rides on the groundwater.
Strip of lawn that’s weirdly green
MediumA seam of grass that grows taller and greener than the rest of the yard — especially running toward the street — is a textbook sign of a leaking sewer lateral feeding that patch of ground.
Sewage coming up somewhere it shouldn’t
CriticalBlack water at a basement floor drain, tub, or toilet base means the line is fully obstructed or collapsed. This is the 'call right now' scenario — 412-265-5479 on a weekend, nights, whenever.
New foundation crack after heavy rain
HighIf a leaking underground lateral is eroding the soil beneath a section of your foundation, cracks start to show — especially on the downhill side of a hillside lot. Often worse after a few wet weeks.
Drain flies that won’t leave
MediumPersistent drain flies or a sudden pest issue in a basement usually means a break in the line somewhere — sewer gas and moisture breeding them from inside the pipe.
Sewer Camera Inspection
We never guess about sewer problems. Before recommending any repair, we run a high-definition camera through your sewer line to see exactly what is going on.
What the Camera Shows Us
- Exact location and depth of the problem
- Tree root intrusion and severity
- Cracks, breaks, and pipe collapse
- Bellied or misaligned pipe sections
- Grease buildup and blockages
Why It Matters
A camera inspection eliminates guesswork. You will see exactly what we see, and we will explain your options clearly. No one should agree to dig up their yard based on a guess.
We also recommend camera inspections before buying an older Pittsburgh home. Many homes in neighborhoods like Mt. Lebanon, Dormont, and Brookline still have original sewer lines that may be nearing the end of their life.
Sewer Line Repair Methods
CIPP lining (cured-in-place pipe)
Best for: Cracked, offset, or root-invaded lines that are still generally the right shape.
A resin-saturated felt liner is pulled into the existing pipe and inflated. It cures into a seamless new pipe inside the old one — no joints, no root entry points.
Advantages:
- Minimal digging — usually just an access pit at each end
- Keeps driveways, patios, landscaping, slate sidewalks intact
- Done in a day once we're on site
- 60-80 year design life on the liner itself
Pipe bursting
Best for: Lines too far gone to line — collapses, heavy deformation, or undersized 4" laterals you want upgraded.
A bursting head is winched through the old pipe, fracturing it outward while simultaneously pulling new HDPE pipe in behind it. Full replacement, minimal excavation.
Advantages:
- Replaces the pipe entirely — new material, new life
- Only access pits needed — no full trench
- Works on collapsed clay, cracked cast iron, and undersized lines
- Can upsize the pipe diameter at the same time
Open-trench excavation
Best for: Bellied pipes, multi-point damage, or shallow laterals that need regrading.
Dig, remove, replace. Sometimes the right answer when conditions (bellies, multiple connections, shallow grade) rule out trenchless.
Advantages:
- Direct visual inspection of surrounding soil and joints
- Can correct pipe slope and re-pitch belly sections
- Straightforward on new-construction or limited-access properties
- Allows for rerouting if the original path was poor
Why Pittsburgh Homes Are Prone to Sewer Problems
The Pittsburgh area presents unique challenges for underground sewer lines. Understanding these factors helps you know when to get your line inspected.
Mature trees, vulnerable joints
Pittsburgh neighborhoods with 80+ year oaks and maples — Mt. Lebanon, Sewickley, Dormont, Squirrel Hill — see root intrusion constantly. Feeder roots find any open joint and make themselves at home.
Clay tile and cast iron past their design life
Vitrified clay laterals installed between 1900 and 1960 had an intended life of 50-60 years. If your house is in that age range and has never had the lateral replaced, the math has run out.
Hillside settlement
On hillside lots, the soil behind retaining walls and under yards shifts measurably over decades. Sewer laterals develop bellies or joint separations wherever that movement concentrates.
The freeze-thaw clock
Our winters cycle the top three feet of soil through freeze and thaw dozens of times a year. Any pipe already slightly compromised — a hairline crack, a loose joint — gets worked on by that cycle every single year.
