"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."

"Given the fact that having a water heater fail is never a fun experience, Joe and his team did such a fantastic job of making the situation so much better for us. Honest, hard working, fair pricing, and quality work. They were honestly a lifesaver given my wife was recently pregnant and being without hot water is not an option. They came out quickly for the estimate and there the next day for the install. Professional and courtesy and all around great team. Highly recommend!!!"
