What is sewer line repair?

Sewer line repair addresses the lateral that carries wastewater from your home to the municipal sewer. Older Durham Region homes often have clay or cast iron laterals that crack, corrode and admit tree roots, and newer PVC lines can be crushed or separated at joints. Hayes Plumbing locates the damage with a camera and repairs the section or replaces the line for homes and businesses across the region.

“Amazing fast service and quality plumber. I had an issue with shower lever not working - turns out the cartridge inside was broken. I contacted Hayes at 445 pm and a plumber was at my place within hours and had the job done in 20 mins. The best part about the service was he was cleaning along the way. Will always use them going forward”
