"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."

"Damian was very professional, came on time and finished the water heater installation in timely manner, I will definitely use his services again."

"First off, the consult was great. I was able to add services to my initial request and received a deal doing so. I also added a second set of services later that month. Adam and Steve completed the work and were completely professional and super efficient. They answered my questions and made sure I understood the work being performed. They worked with my schedule and were fantastic. I had a gas hook-up for a change from electric stove to gas stove - they even took care of the permits and inspection. They removed an old water access point for the fridge's icemaker that was in an awkward spot. They also added a regulator for the water pressure and water filtration system. Fantastic work all around. Should we need any more plumbing/gas work, I would definitely hire them again."

"They installed our malfunctioned water heater the same day. Jonathan and Raul did everything very professionally. We highly recommend them and will be using them for our next projects."
