Sewer Line Repair & Replacement

Common warning signs of sewer line damage include:

• Multiple drain clogs throughout the house simultaneously
• Sewage odors from drains, the yard, or near the foundation
• Soggy patches or extra green grass in the yard above the sewer line
• Gurgling sounds from toilets or drains when water runs elsewhere
• Sewage backup in the lowest drains (usually basement floor drain or ground-floor bathtub)
• Foundation cracks or settling near the sewer line path

If you notice any combination of these, a sewer camera inspection can pinpoint the exact problem and location without digging.

Sewer line repair costs vary significantly based on the method and extent:

• Spot repair: $1,500–$4,000 for a localized section
• Trenchless pipe lining: $4,000–$9,000 for a full line
• Trenchless pipe bursting: $3,500–$8,000
• Traditional excavation replacement: $3,000–$12,000+ depending on depth and length

We always start with a camera inspection to determine the least invasive, most cost-effective approach. We provide upfront pricing with all options explained before work begins.

Trenchless sewer repair is a method of fixing or replacing sewer lines without digging a trench across your yard. There are two main techniques:

• Pipe lining (CIPP): A resin-coated liner is inserted into the existing pipe and inflated. It hardens to form a smooth "pipe within a pipe," sealing cracks and root intrusion points.
• Pipe bursting: A new pipe is pulled through the old one, breaking the old pipe apart as it goes. This is a full replacement without a trench.

Benefits of trenchless repair:

• Minimal landscape and hardscape disruption
• Faster completion (often 1 day vs. 2–3 for traditional)
• No need to remove driveways, sidewalks, or patios

Not every situation qualifies for trenchless methods — severely collapsed pipes or certain soil conditions may require traditional excavation. We assess after the camera inspection.

Absolutely — tree root intrusion is the #1 cause of sewer line damage in Clark County. Roots are naturally attracted to the moisture and nutrients inside sewer pipes. They enter through tiny cracks or joints and grow rapidly inside the pipe.

Over time, roots can:

• Create blockages that cause recurring backups
• Crack and break pipe walls from the inside
• Completely collapse older clay or cast iron pipes

Species to watch: large willows, poplars, maples, and Douglas firs near sewer lines are the biggest offenders. If you have large trees within 20 feet of your sewer line, we recommend a camera inspection every 1–2 years to catch root growth early.

The longevity of a sewer repair depends on the method and materials used:

• PVC replacement: 50–100+ years
• Trenchless pipe lining: 50+ years
• Pipe bursting with HDPE: 50–100+ years
• Spot repairs: 20–50+ years depending on surrounding pipe condition

Modern pipe materials (PVC, HDPE) are resistant to corrosion, root intrusion, and chemical degradation — far superior to the clay, Orangeburg, and cast iron pipes found in many older Southwest Washington homes.

In Clark County and most Southwest Washington jurisdictions, yes — sewer line repairs and replacements typically require a plumbing permit, especially if the work involves:

• Replacing sections of the main sewer line
• Connecting to the city sewer main
• Excavation in the public right-of-way

We handle all permit applications and inspections as part of our sewer line services. Permit costs are included in our quotes so there are no hidden fees. Working with a licensed plumber ensures the repair meets code and passes inspection the first time.
