Sewer Line Leak Detection & Repair in San Luis Obispo
Many SLO homes sit on slabs or crawlspaces with original cast iron drain lines. Over decades, cast iron can rust through at the bottom of the pipe, leaking slowly under floors before anyone notices.
What affects the cost?
Cost depends on how hard the leak is to reach, whether it is under a slab, the repair method, and floor or landscape restoration. Finding the exact spot first keeps repair costs down. Always ask for a written quote and a copy of any camera footage before work begins.
Helpful tips
- Act early: slow leaks damage subfloors and foundations.
- Ask for the camera footage of the leak.
- Check whether your insurance covers resulting water damage.
