Since I have used this company through my previous job for many many services, I called them for service at my own home. They are polite, prompt, honest, hardworking, clean and respectful. I had a backup in our basement shower and not only did they come and clear it first thing the very next day, the tech also was kind enough to clean the sewage out of the shower and he made absolutely no mess whatsoever in my home. The service was quick, efficient, and perfectly done. I would recommend Oliver Plumbing to any and all customers needing prompt quality work done for any residential or commercial plumbing or heating repair required.
