This was an evening emergency call to an answering service. I was quickly called back by Cassidy Plumbing and informed of response and fees which I agreed to.I received a call from responding plumber and given a time frame of arrival. Upon arrival the plumber listened to me and communicated to me what he will do to stop a water heater leak which he completed.Upon completion the plumber cleaned the area he worked in and will notify the office on a follow up call and further repairs needed.For the response and assistance in this emergency it was definitely peace of mind and a great job by Cassidy Plumbing.

We had a problem recently with a bathtub that wouldn't drain after a bath. Cassidy Plumbing came that afternoon and fixed the problem immediately. We have had problems in the past with plumbers that take their time in solving the problem. When you have a problem you want it taken care of quickly. We are very satisfied with Cassidy and have made them our go-to plumbers. This takes a load off our minds knowing that we will have reliable service going forward with a crucial part of living space.

On April 30, I called Cassidy Plumbing for the 1st time. Teressa asked me about my plumbing problem, I said, our Toto Toilet would not stop filling. Terresa said technician Chris will be over in the afternoon. Chris arrived, solved the toilet filling issue. As he was flush testing the toilet, Chris asked if I heard the pipes hammering? I said yes, they do that regularly. Chris asked to test the water pressure in the house and found the pressure was very HIGH.Chris suggested he remove, clean, adjust and reattach the pressure relief valve. He did and the valve would not lower the water pressure in our house. So we had Chris install a new pressure relief valve. When Chris was done, he kept the panel open for me to check the valve the next morning. I checked, the new valve was damp (a very tiny leak). I called Cassidy Plumbing and another technician arrived with an apprentice who is learning the craft. They removed the new valve. Checked it and reseated it. Again, leaving the panel off for me to check in the morning. Well, it was damp (still leaking). I called, and Teressa sent Chris back. When he checked the new valve, Chris found the new valve had a hair line crack. So, a new, new pressure relief valve was installed and, it works just fine! And our pipes do not hammer. Through the three visits, the Cassidy Plumbing "Team" did everything needed to solve our problem. We are very pleased to have found Cassidy Plumbing to handle all our plumbing needs.

We've used Cassidy Plumbing on several occasions and each time....they are completely transparent and thorough. We found out the pipe under our tub had broken and we needed an entire new one installed. Called the after hours service on Thursday and they were able to come the very next day. George and his assistant arrived at around 12:45 and completed the entire job at around 3:00pm. Went through everything they did and where other things would possibly need repair in the near future. I trust Cassidy with our plumbing and look forward to working with them again!

We recently had a new toilet and bidet seat installed. The young men removed the old toilet very neatly and efficiently. They found the existing gasket under the toilet base needed to be replaced and took care of that. They also found that the cold water hookup had some evidence of rusting and did not line up well with the new toilet. In order to install a new line they needed to open a small access point in the ceiling of the boiler room. Once this was done, they patched the ceiling. They did a beautiful installation and showed us how the bidet functioned. The work area was spotless when they were done and they removed all of the packaging and debris. Both young men were friendly and professional. I was very comfortable having them in my house and would not hesitate to have them back to do other projects!!

Cassidy Plumbing is now my first call for any plumbing issues.I recently had a bad leak in my well water tank late on a Thursday night and put in an emergency call to Cassidy. The owner [Patrick] got back to me [via his phone while he was out of the country] and told me which valves to close and power source to stop the leak for the evening. By the time I called the office in the morning the office staff [Bernadette & Theresa] had already known about the issue, ordered and located the right tank and was able to have their staff install it the same afternoon. So....in less than 24 hrs, Cassidy Plumbing was able to get our facility up and running by Friday afternoon before the weekend. Also, the cost was within the estimate which is appreciated because there are companies who would take advantage of a customer's vulnerable situation, not Cassidy Plumbing. I highly recommend them!!

On behalf of the D'Amore family, (Peter and Yolanda) we would like to thank Cassidy Plumbing and their team for installing new water lines and tapping a drain for a washing machine hookup in our home. Bernadette was instrumental in arranging the service appointment, processing the building permit, and keeping in touch with us throughout the entire process. The tradesmen, Bobby and Dino, were punctual, friendly and professional. They did a great job. A shout out to Joe as well who made himself available to meet with the building inspector upon completion of the work. Thank you all for a job well done! This is our second time contracting Cassidy Plumbing but it won't be our last. They are that good!
