How Much Does Trenchless Sewer Line Replacement Cost on Average?

Trenchless sewer line replacement cost is not a flat rate; Apollo Plumbing confirms pricing only after a camera inspection and on-site evaluation. The biggest price drivers are how many feet of pipe need rehabilitation and which trenchless method fits best (spray-on coating or CIPP lining). Trenchless is designed to be quicker, cleaner, and more affordable than digging when conditions allow, and our crews regularly complete these projects around Bothell homes with minimal property disruption. For diagnostics, a camera inspection is complimentary for Apollo A-List members (regular price $489).

What most affects your quote:

• Total pipe length involved
• Depth and access (under landscaping, driveway, or slab)
• Pipe material and current damage (roots, cracks, collapse)
• Scope (spot repair vs full line) and any required surface restoration

Schedule a video camera inspection to get a precise project scope before you decide on repair or replacement. <br/> Updated: 2026-03-10 <br/> Need help in Bothell, WA? Call (425) 387-1507 or book online. "Sewer fixed and working great!" — Douglas R.
