I needed my kitchen faucet and the strainer replaced after leaving for vacation in the cold winter and the pipe bursted. I saw their truck parked in the shopping plaza I was coming out of in Orange, CT and decided to give them a call. They gave a fair range of what to expect in terms of cost to repair and replace with the Kohlers faucet I got from Costco. The service tech Ryan arrived early and was thorough and efficient. He made sure everything was setup correctly and that there were no leaks elsewhere. They did such a good job at a fair price that I had them fix the toilet upstairs and then come back another time to fix the leaking outside faucet. I highly recommend and they are now my go to as a homeowner in West Haven if I need any plumbing work done. The call out fee of $105 is deducted from the final cost of the work I had them do. I think it’s reasonable considering I had plumbers from Facebook groups quote/ask me for double just to come out and assess the problem. Or the one previous plumber that did come out for free ended up quoting me over $1,000 to just fix the kitchen sink. I’m glad I found them and I also appreciate how they emailed a clear invoice after. The little things makes working with them easy they are an upstanding business.

Would give 6⭐️s if we could. Absolutely fantastic experience with Onze from start to finish! The team was professional, punctual, and tidy throughout the entire boiler installation. Everything was explained clearly, the work was completed to a high standard, and you can tell they genuinely care about customer satisfaction. Wouldn’t hesitate to recommend — 10/10!

I was away for a couple of weeks and returned home to some kind of leak from the furnace. Onze was referred by my regular furnace company who was unable to get to me with the urgency required to assess the situation. One phone call to Jason and 30 minutes later there was a professional named Dave on the job. Jason and Dave worked together seamlessly to get the parts needed, and then Dave did the work in less than 2hours. Onze exceeded my expectations on the speed, quality and cost of fixing the problem. I recommend them Highly!

Jason was incredibly professional and responsive. He came out the same day to resolve my tankless heater issue. His prices are very fair. Thank you.
