"I had plumbing leaks in a couple of places, but the men that did the work went above and beyond by replacing every component involved top to bottom to ensure there would be no leaks for a long time to come. Very satisfied with the quality of work as well as how quickly it was done."

"I've used All Star Rooter on three occasions and have been very pleased with the work provided. Always professional, punctual and careful, they are specialists. An important indicator of their skill is their position in the industry - three different plumbing companies have recommended All Star Rooter. They will calmly approach a stressful situation and do their best to reach a successful outcome. On this occasion they were able to clear an on-going clog efficiently."

"Went well. I thought that I might need a new trap or elbow since water was leaking. As it turned out, it was the sprayer that was leaking and not the elbow. The tech did not try to oversell me all new plumbing and I appreciate that."
