How Much Does Trenchless Sewer Line Replacement Cost on Average?

Trenchless sewer line replacement typically costs $8,000–$15,000+ with Gold Star Plumbing, Heating, & Cooling. The biggest swings come from how far the pipe runs and the conditions around it underground. We use flat-rate, up-front pricing, and the $179 Diagnostic Visit is waived with repair after we confirm the scope with a camera inspection. Financing options, including 0% with approved credit and low monthly plans, are available. We routinely complete these projects across Long Island, including work near Hempstead.

What most affects price:

• Total linear feet and depth of the line
• Number of access pits and surface restoration needs (lawn, driveway, landscaping)
• Pipe diameter/material and damage severity (roots, offsets, collapses)
• Required code-compliant connections and inspections, plus any pre-cleaning like hydro-jetting

Final pricing is confirmed after on-site diagnostics and a camera inspection so you can choose repair or replacement with clarity. <br/> Updated: 2026-05-13 <br/> Need help in Hempstead, NY?
