Customer reviews
“Stan was thorough and answered my questions about my old water heater and what it needs according to code and safety.”
“I had a tree root that busted through my sewer lateral as well as some bellying in the pipe that caused ponding. Elite was able to get the call Friday evening and have the job finished by Sunday morning. Omar was a friendly and knowledgeable technician who made sure we understood the improvements.”

A recurring blockage deserves a better look than another quick clearing. Tell dispatch how often it returns, which fixtures are affected, and whether anyone has already inspected the line with a camera.
A problem shared by toilets, tubs, or lower drains can point beyond one fixture. A camera inspection can help locate the obstruction or damaged section before sewer-line work is proposed.
Note the unit type, visible leak location, any error code, and whether every hot-water fixture is affected. The visit should determine whether repair is viable and what replacement would involve if it is not.
