We had the outdoor faucet break underground while washing the car after hours. Went to “google” plumbers and I remembered the “Happy Hiller” commercials from the radio and called. Great experience from their answering the phone, returning to confirm a plumber was on his way, to the young man capping off the pipe. All within a short amount of time. Their availability mattered to us. Close

We had a drip in our bathtub area that needed to be addressed, some issues with toilets and water pressure that was straining our pipes. Making an appointment online was easy and we had someone here the next morning, right on time as promised. Communication from the office and the pro was great. David B. was super helpful, professional, friendly, respectful of us having a cat to keep inside, etc. We are very happy with our choice to go with Hiller! Close

Paul from Hiller came to our house and was here on time, really friendly to deal with and he was able to help get us taken care of quickly. We bought our home a year ago and the toilet in our master bath was always slow to flush. Sadly it was overflowing and we couldn't clear it ourselves. Paul came out and found that 26 feet into the drain line there was a blockage. He was able to get the entire thing cleared out for us and showed us what he did so we understood the process. These type of repairs aren't cheap but the quality of their work makes it worth it! We are really glad we called Hiller to get this repair done and would definitely use them again. Five Star Review all the way! Thank you so much Paul! Close

Hiller sent expert specialists, technicians, and a project manager to my home to discuss my hot water issues, to include all facets of switching from a tank to tankless water heater, which I subsequently requested they install. During the discussions, I also requested the installation of a whole house water filtration system in addition to my request to upgrade to a tankless water heater. Work expertly accomplished. Great company, and highly skilled team of folks across the board; they did a fantastic job. I am am a VERY happy customer. UPDATE: Anthony and his expert technician installed a dehumidifier on 27 July 2022; my review stands, outstanding service and crew!

The service was so quick! I booked an appointment for the next day, the messaged me that they had an immediate opening. I was able to have my outlets fixed within a couple of hours of visiting their website. The man who came to fix it was very nice! He explained things in ways I could understand. They also got to the root of the problem, without over charging or trying to make it a bigger problem than it was. I 100% recommend. Close

We needed the power cut to two extra stove eyes in the kitchen. Jay arrived on time, and knew just what to do safely and efficiently. Would recommend!
