"I've called Sila before to work on my HVAC unit and realized they offer plumbing services when my tank-less water heater stopped working. They were able to come by that day I called to see what was wrong. Once they were onsite they deterimed my hot water valve stopped working and were able to replace it and got my hot water working in no time."

"Joe is an excetant professional contractor, he provided a very competitive quote for the replacement of a propane hot water heater. He was able to do the work the same day as he provided the quote. Work is clean neat and very professional looking. Would not hesitate to contact Joe again on any future heating and plumbing needs."

If you need a reliable install, I highly recommend Expedition!"

"Daigle were quick to reach out to quote me for the work we needed - replace a water heater and arrived early! Very personable, professional. However, pricing was an issue. They were way outside of what other plumbers charge for this service and way outside of what Angi's has listed as average project costs.

"Wonderful service from Adam! My water heater was struggling to keep up with my wife?s long showers - which by the way she heats them up hot as hell! ? Besides the point, Adam recommended sizing up the water heater in order to keep up with the demands of some crazy hot water. Incredibly fast installation process and Adam was really friendly. I would definitely recommend him to all my friends who are looking for a plumber. You should certainly give him a call!"

"Addario's Services did a great job installing a new high efficiency combo boiler in our home. After I requested an estimate, I got a quick call from the office to schedule a time for one of their comfort advisors to come out to our home. Sam, my comfort advisor was very knowledgeable, and I appreciated his low pressure presentation. Once the work was booked, because our installation was complex, Joe came out and came up with a plan to vent the exhaust on the side of my house to minimize the number of pipes on the front of my house. The installation went very well, and they installed a temporary water heater so we were only without hot water for less than a day. For the day we were without heat, they brought in plenty of space heaters to make us comfortable for that night. When the installation was complete, the installation technicians took lots of time to explain the operation of the new system, and to answer any questions I had. The system is working great and there have b"

"Keith did a great job. Very professional, right on time, got the job done fast and done right at a very competitive price. Took the time after installation to show me the job and explain the features of the water heater, and also gave me information on how to properly maintain the unit and other services he offers. I would strongly recommend anyone consider Keith's services."
