They were able to set up an appointment that worked well for me, were here when they booked it, their service man addressed all my issues, explained what was needed in a very positive way, and that’s why I always use local contractors, they’re the best

Complete rip off. They use pressure sales tactics to overcharge, sending 2 guys to do bare basic plumbing job on a toilet valve. After overcharging, can’t even finish the job correctly. What exactly did I pay for? Do yourself a favor, hire someone else.

We needed a new oil burner and Pat made the time to see us after hours to accommodate our work hours, explained the problem clearly, and replaced it quickly and professionally the next day.The work was high quality, the price was fair. Bobby the technician and his crew were excellent respectful young men and left everything clean and in place.It’s hard to find someone this reliable and honest—highly recommend to anyone who needs plumbing work done!

I used Cassidy for 3 plumbing jobs in my home this year. Very satisfied with their work. The office staff is pleasant and helpful. Each tech sent to my home was friendly, thorough and professional. Would highly recommend.

I used Cassidy plumbing to prep my tankless combo boiler for the winter. Unfortunately, although my system needed more work than I had originally planned, plumber Joe C was able to explain what needed to be replaced and why in great detail. He was able to make all the repairs and completely flush all the air out of the system. Something the last plumber didn’t bother to do. Although all plumbing services are expensive nowadays, I really like that they have set pricing for all of their repairs. For each individual part that you need replaced, they give you a flat rate which includes the part(s) and labor. Highly recommended I will be using Cassidy plumbing again in the future.

This place has been a beacon of hope for my previously sick 12 thousand pound cast iron rusty pipes. I recently had Joe come by with his techs to replace the ancient pipes in my basement and to modernize them to properly vented PVCs and it's been a huge game changer. The water in my house actually drains instead of getting caught in oddly sized big>small>big pipe conversions. Who would have thought that plumbing to code is so much more efficient than going with the "playskool - my first drainage system" setup.

The first two pictures are the old lead pipe parts from ancient Rome.

Cassidy Plumbing and Heating really came through. Had a last minute non-emergency. They were able to fit me in the next day first thing in the morning. Tommy was an excellent tech and did a thorough and clean job. New mixing valve, and cleaned up some old copper in the shower. He is friendly and explained all of it. Thanks!

I had an emergency and they came fast!!! Tom was very patient and helpful. I have a pretty small crawlspace and had a bad leak!!! Tom went and found the leak like if his life depended on it… they are very professional and I felt pretty confident and satisfied with the service. The price was actually less than what I was expecting! Cassidy plumbing will be my go to plumbing company. I will refer them to anyone who needs plumbing services.

Cassidy came out to help us with our garbage disposal drain lines. He was very honest and knowledgeable. His prices are very reasonable and he was so easy to schedule and work with. Thank you Cassidy! We will for sure be using you again if the need arises! We appreciate you!

Jude J

We were stuck! Our countertop and sink was coming and our plumber, scheduled to connect the faucet, drain, and filter, was ill. Cassidy Plumbing was able to help us, and was amazingly responsive. Bobby came when expected, did a fine job, and left everything neat and clean. They are not cheap, but if they were, we probably would have had to wait a week or more. They discounted the filter install, so that helped.

Beverley Joseph

I recently had a pipe leaking near my boiler and called Cassidy Plumbing for help. I was impressed by their prompt response—the service person arrived within an hour of my call. They quickly identified the issue and efficiently fixed it. The whole process was smooth and professional. I'm grateful for their excellent service and quick resolution. Highly recommend!

I recently had the pleasure of working with Cassidy Plumbing and Heating, Inc. for a boiler service, and I cannot praise Joe Garcia and his assistant enough for their outstanding work. From the moment they arrived, it was clear that they were knowledgeable and dedicated to their craft.

Joe and his assistant performed a thorough inspection of my boiler and quickly identified several developing issues that required attention. What impressed me most was their approach; they were not pushy at all and took the time to explain the problems and potential solutions without applying any pressure to make immediate decisions. They provided on-the-spot estimates, which was incredibly helpful for my budget planning.

I also want to acknowledge their hard work—after diligently servicing the boiler, both men left covered in soot, a testament to their diligence and commitment to getting the job done right. It’s clear they take pride in their work.

Additionally, Bernadette's assistance in setting up the appointment was seamless and very friendly, making the entire process hassle-free.

Overall, I highly recommend Cassidy Plumbing and Heating, Inc. if you need boiler service. Joe, his assistant, and Bernadette exemplify excellent customer service and professionalism!

Cassidy Plumbing exceeded my high expectations based on their highly-rated reviews. Their team handled my urgent pipe repair with exceptional care, from the initial office contact (Kai) through completion (Richard). Every interaction was marked by genuine respect and professionalism – a refreshing change from my previous experiences with repair services. The quality work was fairly priced, making it easy to confidently recommend their services to anyone needing a reliable plumber in the area.

Cassidy Plumbing has great customer service and is very reliable. They always do their best to fix things efficiently and quickly. I highly recommend their services.

Leah Price

15:36 22 Nov 24

I put my faith in Google reviews when the plumber I was initially referred to was too booked up to see me soon enough (in fairness to them, i called at the end of the week and next week is Thanksgiving so there are fewer work windows) so I looked up another plumber in the area and chose the best reviewed one, which was Cassidy! They were able to come out the next morning and were upfront about all costs. Everyone from the woman I spoke to on the phone to the workers were friendly, honest, and knowledgeable and they worked efficiently. I'm very pleased 😊 I will call them again the next time I need a plumber!

Kandice Law

15:34 30 Oct 24

I’ve used them a few times for various kitchen sink issues (which they predicted but didn’t pressure me into fixing). They come out quickly, are up front about pricing and what needs to be fixed, and get it done quickly. They even send a text with a picture of who is coming to your house so you know who they are. I highly recommend!

Vicki Torres

13:35 29 Oct 24

Thank you for giving me peace of mind by fixing my plumbing issues correctly. Your technicians were knowledgeable professionals who were courteous and respectful. They listened to the concerns and their suggestions were much appreciated. Doug did an excellent job and so did Chris who was here for another issue. I like the quality work they both did. Thank you again for the excellent service.

1st time using Cassidy and not the last. My new plumbing and heating company. Dan is the man. His knowledge of my Navien is exactly what I needed. He is personable and explains in layman’s terms how my system works, what is a problem, and how to move foward. Thanks Cassidy and thanks again Dan!

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!

They made some recommendations, which i followed through. Through the entire ordeal,Bernadette and Theresa kept in touch on a regular basis. I highly recommend Cassidy plumbing.

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!!

Pete M

20:12 06 Mar 24

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!!

John Fitzpatrick

22:56 20 Feb 24

Cassidy is professional, punctual, and clearly communicate. Thank you for guidance and repairing our corroded pipe. Thanks for installing the valve for the expansion tank too! I didn’t realize how much money that will save us in the future. 🙏🙏

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!

Preventative Plumbing Maintenance: Protect Your Home and Business in Nelsonville, NY

At Cassidy Plumbing and Heating, Inc., we advise on routine maintenance to catch small problems before they develop into larger ones. Much like a car requires consistent care for smooth operation, your plumbing system needs regular attention to work efficiently. We also offer flexible financing options to help manage the cost of necessary plumbing services. Here’s why preventative plumbing maintenance is vital for safeguarding your home or business:

Early Problem Detection
Routine plumbing checks allow our skilled plumbers to spot potential issues before they cause significant damage. Whether it’s a minor pipe leak, an aging water heater, or a clogged drain, early detection helps prevent bigger problems. Addressing these concerns early minimizes the risk of water damage and expensive repairs.
System Efficiency
Regular maintenance keeps your plumbing running smoothly. For example, periodic drain cleaning prevents blockages, while maintaining your water heater ensures a reliable hot water supply. An efficient system saves you both time and money on repairs and energy costs.
Prolonged Lifespan of Plumbing Systems
Routine maintenance extends the life of your pipes, water heater, faucets, and other fixtures. By tackling issues like corrosion and mineral buildup, we help prevent the need for early replacements. This ensures your plumbing continues to serve you reliably for many years.
Preventing Water Damage
Water damage is one of the most expensive problems a homeowner or business can face. Leaks, burst pipes, and malfunctioning water heaters can lead to costly repairs. Preventative maintenance minimizes the likelihood of these issues, protecting your property from water damage.
Avoiding Plumbing Crises
Emergency plumbing issues, such as a burst pipe or flooding, can disrupt your home or business and lead to expensive fixes. Regular inspections reduce the likelihood of such emergencies. Preventative care addresses small concerns before they escalate into significant problems.
Water Conservation and Savings
Maintaining your plumbing system ensures efficient water usage. A well-maintained system prevents waste, helping reduce utility bills. Whether it’s fixing leaks or optimizing your water heater, preventative maintenance conserves water and saves money.
Peace of Mind
One of the greatest advantages of preventative plumbing maintenance is the peace of mind it offers. With regular professional inspections and care, you can rest assured that your plumbing system is in good hands, allowing you to focus on what matters most without worrying about unexpected issues.
