"After spending 2 days trying to find someone to replace my hot water heater, Home Advisor recommended this company. They fit me into their schedule the same day and it was installed about 4 hours after my initially contact with them. Casey and Phil were great. Had them look at a couple of other minor future projects to do while they were here. Will definitely hire them again."

"After having our water heater and gas boiler inspected, we learned that the water heater needed to be replaced and the gas boiler required thousands of dollars in repairs.  I originally contacted Peter Zereski about the water heater and also mentioned the issue with the boiler.  Peter carefully answered all of my questions and then asked if I was interested in a tankless unit that would supply all of the hot water to the house as well as the heat.  I ended up going with the tankless system which, after rebates, costs about the same as buying a new water heater and repairing the boiler.  Not only that but we now have a high efficiency system.  Peter was extremely knowledgeable about plumbing and very responsive.  The installation was a major task and he and his team managed to complete it within 3 days.  I am very pleased with how the installation turned out and will definitely use his services in the future

"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."

"I had to repair my heating system during this winter. A few months later I used them to replace my very old water heater system. They were very fair in their pricing and cleaned up the whole area very well. They checked my thermostat to be sure I understood how it worked. They were very patient with me as I tend to ask a lot of questions. They were very prompt and professional. I would recommend them highly to do your next service job."
