ZSL Plumbing just installed a new boiler in our home and were an absolute pleasure to work with. Our new boiler system is neat and they labeled each zone for us. John and Robert were extremely responsive, patient, accommodating and were able to answer all of our questions. Our home was left clean and we couldn’t be happier with their work. Highly recommend ZSL!

We are so glad we found ZSL Plumbing through our Yelp search. After speaking with several other companies, ZSL was the most responsive, friendly, and accommodating. They explained options to solve an issue with our baseboard heaters and did not push me to do more than needed. They arrived on time and repaired the unit quickly and efficiently. A few hours after the work was done, we called with additional questions, and they responded right away. You could not ask for a more honest, professional, and skillful company than ZSL Plumbing. We definitely plan to work with them on any future projects and happily recommend them!

We have found our next generation family plumber! Rob at ZSL Plumbing is personal, professional and thorough. He explains everything. *They are prompt in returning calls. *They schedule an appointment sooner rather than later if there is a problem that could escalate, e.g. leak, etc. *They respect the home, use the basement door,instead of going through the home. *They always spend time time on the end result to discuss the problem and its resolution. *Always reinforce to call if the problem reoccurs. *They never rush through your job. Very happy to recommend them. We now know more about the world of sump pumps!

I highly recommend ZSL Plumbing. Great team, extremely professional, friendly and knowledgeable. They did an amazing job on my new bathroom and addressed several other items that have been on my list for years. It's comforting to know I have their number for any plumbing needs or emergencies in the future. Patrick D

I chose this Plumbing Company after looking at many Plumbers over the internet and looking at the reviews. These guys were extremely professional and experts in their field. They repaired a very difficult connection and piping work in my garage ceiling to my bath tub and solved my water leak problems. I STRONGLY recommend them to anyone needing any type of plumbing work. Thank you ZSL Plumbing , I will call you again in the future.....
