"I worked with Jesse to help with a clogged bathtub drain after I tried plunging it myself. I explained over the phone that I was dealing with backflow problems and each time I used the bathroom sink the water would end up back in the tub. Unlike another plumber who said they would need to charge me to snake both the tub and the bathroom sink, Jesse explained it would likely just need to be the sink and there is an issue in the shared drainage pipe. Jesse communicated clearly when he'd arrive and on his availabilites, and helped resolve the issue quickly and cleaned up after himself. He also gave me additional advice on how to manage my drainage issues in the future, and another toilet problem I had. Good guy to work with, and got the job done. Would hire again."

"Tony was very pleasant to work with. He accommodated my schedule, even with a big winter storm that had just rolled through. Tony and his team finished the project in about a day and a half and I couldn’t be more pleased! Not only was the job exactly what I needed/requested, but it was a very neat and clean job. His team respected my house and left the work area spotless. I will definitely call Tony if I ever need anything plumbing related."

"I had lost water pressure on Saturday and made a emergency call to a unknown company from google. I talked to a person immediately from Cassidy Plumbing and was told I would get a call from an employee in one hour. An employee called and would come over in 15 minutes. I was amazed at the response time. He check out my water system thoroughly and told me that I wasn't getting water in the well tank causing me to lose pressure but also I was not getting any pressure straight from the well either. It was either the water pressure tank with the pressure switch or the water pump that was causing this problem. The pressure gauge was also broken. He explained fully what needed to be done, the price for each issue and since he was not able to do anything until Monday, I was first on the list.
Cassidy Plumbing called me in the morning and told me that they would be their in one hour. They came promptly and went to the well tank first and found out the pressure switch had corroded and the well tank was also not doing it's job. The tank was about 15 years old and the switch was more than 25 years old. I was told and saw everything that needed to be replaced and the price. When replacing the valve close to the water filter housing the piping broke off and upon looking at it this was corroded too! I was able to get a discount for the water filter housing since they were working on that section of piping and it was unexpected. Afterwards they tested the water pressure to make sure all was working and that the register near the pressure switch was functioning.
My water room is the size of a closet. Inside is the water heater, water softener system (tank for salt and two tall cylinders), electrical box, telephone box, cast iron plumbing for toilet and the well tank. It was tight to say the least and they did a neat job of putting everything together and cleaning up.
I have had to replace my well pump and another time the electrical wiring to the pump and both these companies could not compare to the professionalism and services that Cassidy Plumbing and Heating."
