"We have had several Sila visits in recent months - all exceptional. VISIT 1: We had old pipes and valves that limited our dishwasher, so we had that replaced. While there, the Sila agent suggested we replace some of the attached lines and managed to streamline our hookups by removing some of the unneeded valves and connections no longer needed. VISIT 2: We similarly had a great visit and instal from David, who did a very beautiful install on our new water heater. He removed the broken unit, improved the connection design, put in improved valves and labelled each with a tag, then tagged other connections through the basement."

"Called them up for replacing my cracked sewage pipe in the basement. They came out, gave a free estimate with reasonable pricing and immediate availability. Did a courtesy camera scope of the entire sewage pipe out to the city line while the pipes were open. Finished work within estimated window and charged at the original estimated price. Polite and clear with communication."

"The company was professional and responsive from the consultation to the office staff to the various people who worked on our project. I had tried to contact about 10 companies to get our heater/ on demand hot water heater replaced. Addario's was the only one who responded immediately and was able to fit us into their schedule to get the work done. We had contact with at least 8 staff people in various capacities, and all were professional, polite and knowledgeable. We also appreciated the senior discount for our project and assistance with the MassSave rebate process.. It has been difficult for us to find service people since we move to Gloucester. We were surprised that the company services this area and we would definitely use them again for plumbing or electrical services."

"Replacement was urged by technician after routine inspection of heating system. Water heater wasn't part of the service but, tech checked it anyway. Nice enough of him to do that. After showing me his concern (legitimate) I asked for a quote to replace. Outrageously expensive considering cost of materials. Later learned techs are incentivized to sell service and parts. Dropped them as my go to plumbing and heating guys. Water heater still working 3years after urgent replacement was quoted"
