Read what some of our past plumbing and heating
customers say about us.
“Onze Southern Connecticut Plumbing and Heating were introduced to us by a client. Will Onze and his commercial team of installers were professional, followed all safety requirements, neat and responsive. The Onze team was always on time and worked through any questions on this design build project. I recommend Will Onze and the Onze team and look forward to working with them on future projects.”
Jason Henry
Owner/Project Manager, JMLS
“We had Onze Plumbing do all above ground and mechanical plumbing for our 10k sq ft food manufacturing facility. Will was hands-on throughout the entire process, fairly priced, and has a very professional staff. Whenever I asked questions the staff and foreman on site were able to answer my questions thoroughly and accurately. The plumbing for the project was done on time and impeccably. I highly recommend Onze for commercial work and welcome anyone to reach out and ask me personally about my experience.”
Don Carlo Battimelli
Co-President, Battimelli Foods
“Thank you so much for your hard work on the T-Mobile Danbury project and for ensuring the project was so successful. This one had some challenges in the beginning but your ability to pivot quickly enabled the project to stay on schedule and finish on the original timeline. I appreciate your effort and hope to work with you soon.”
Thanks,
