Sewer Line Services for Longview Homes and Businesses

Common Causes in Cowlitz County

  • Tree root intrusion that cracks joints or blocks flow
  • Aging clay or cast-iron pipes that corrode or collapse
  • Soil shifting and heavy rains that create bellies or misalignments
  • Grease and non-flushables that accelerate buildup and blockages

If multiple fixtures are backing up or you notice lush patches over the line, a camera inspection can confirm the cause and location.

Repair vs. Replacement

Not every problem requires a full dig.

  • Spot repair is ideal for localized cracks or intrusions.
  • Sectional replacement addresses longer damaged runs.
  • Full replacement is recommended when the line is severely deteriorated, undersized, or repeatedly failing.

We will compare costs, timelines, and restoration needs, and include financing options so you can decide with confidence.

Trenchless Options

Many Longview properties qualify for trenchless methods that minimize disruption to landscaping and hardscape.

  • CIPP lining forms a seamless pipe inside the old one.
  • Pipe bursting replaces a failed pipe by pulling a new line into the same path.

These methods reduce surface impact and can shorten project timelines. For details, see your dedicated Trenchless Sewer Repair page.
