Why It's Critical:

Prevents Sewage Backups: A damaged or collapsed lateral can send sewage back into your home

Protects Public Health: Ensures proper containment and removal of wastewater

Code & Compliance: Most municipalities require replacement when selling or remodeling

Frequently Asked Questions

What is a sewer lateral, and why would I need to replace it?

Your sewer lateral is the underground pipe that connects your home’s plumbing to the city sewer system. If it’s cracked, collapsed, or blocked by roots, it can cause sewage backups, slow drains, or health risks. Many Bay Area cities require lateral upgrades before a home can be sold or remodeled.

The open trench method allows for full visibilityprecise slope correction, and secure, watertight connections — making it the most trusted solution for long-term reliability. It’s ideal when dealing with older pipes, major damage, or when local codes require visual inspection.

Most open trench replacements take 2 to 4 days, depending on trench depth, pipe length, and access. This timeline includes excavation, pipe installation, inspection, and backfilling — though permit approvals and city inspections may add extra time.

  • Spot repair is quicker and less expensive but only fixes a short section and may not address underlying issues.
  • Full replacement is more comprehensive, ensures code compliance, and typically lasts 50–100 years.
    Our technician will provide clear pricing and help you weigh long-term value vs. short-term fixes.
