Fast friendly service

Fast friendly service. We had a non-emergency is a blockage. They said they would get us on the schedule for tomorrow. However, they called a short time later and said we’re passing by And called to see if coming by in a half an hour would work into our schedule. It did. They came by and quickly assessed and fixed the problem. They were very very friendly

Courteous Professional Service

Imperial Plumbing called me promptly to set up an initial appointment to diagnose my problem. They arrived on time for the first visit and early for the second visit. The two plumbers that came to replace my water heater, Toby and Jeremy, were very courteous and professional. I am extremely pleased with their work and the entire repair/replacement experience.
