    I had two plumbing services out on a Friday after a sewage line blockage in our new house (that was missed on the home inspection) - neither could solve it (lacked the equipment) and both recommended I contact Roys. I went online and the reviews seemed a little mixed and they were not open over weekends (we had to put our house guests in a hotel over the weekend - an expensive lesson in believing what plumbers say on their websites or what home warranty providers claim). I thought it was worth giving them a try and was very impressed.

    I can’t say enough about Roy’s! Top notch customer service, incredibly thorough and helpful. Hard to find a company like this anymore.

    Our plumbing started backing up/moving slow one night. We assumed our tank was full and needed to be pumped (a first time for us). I got a referral to Roy's and called them first thing in the morning. After describing what happened the person on the phone agreed that was probably the case and would send their pump truck out. 2 men showed up in under an hour (I apologize but their names slipped my mind). They introduced themselves, exchanged a few words and started in checking the tank. They were kind, courteous, personable, and put us at ease pretty quickly.

    A disabled senior 3 Hour Plumbing Nightmare. After two and a half hours the worker decided to bring in the right piece of equipment to do the job. Plus $500 to remove / replace a toilet. $1,250 to unplug a toilet drain!!! Said overtime should have been added to that and showing up at 4pm. Left job unfinished with glass they broke in drain - I had to clean up shreds of glass off floor, and clean and caulk toilet. Yikes! - Priced like but Not licensed plumbers - No Repairs you have to call someone else.

    I had an external drain that was running slow. Curtis came out and cleared it - 150 feet out - then cleared if again from the lower end. Incredible job and Curtis was very patient. Highly recommend

    Response from the owner

    Hi Bill, Thank you for the positive review! Curtis is very good at what he does, we are lucky to have him on the team.

From the Google listing, checked 30 Aug 2026.

Several customers describe fast crews and stubborn blockages cleared. Derek says two men showed up in under an hour after a morning call, then checked the tank and walked his wife through what they saw inside. Curtis comes up by name more than once, snaking a line almost 100 feet after removing a toilet and clearing a slow outdoor drain from both ends, and Susan writes that the crew "got right to the problem".

Before You Call

Pumping is the service at the center of Roy's work, so an overdue tank or a house closing on a deadline both start with the same call. The question worth asking on the phone is how soon a pump truck can reach the property.
