"Discovered our 6 yo gas water heater developed a leak. Decided to call on these guys as they provide the annual maintenance for our A/C and furnace. Called early AM and they were able to have a service technician on-site within 3 hours. After inspecting the tank and finding the source, the technician proposed the replacement options. Although most seem costly, the technician did a great job of explaining the work involved and how much time it would take. After doing some research, I went with these guys....and everything went to plan. Was able to schedule an appointment that worked for our schedule. The same technician came back out with another colleague. The entire job took about 5 hours. They answered all my questions. And they worked very neat. Yeah, they weren't the 'cheapest.' But, they corrected some previous issues, worked efficiently and completed the job correctly and in relatively quick time. They new exactly what to do and how to do it. Very good experience. Thanks, SILA team!"

"Included in the price of the 50 gallon water heater I needed was the plumbers picking up the new water heater, transporting it to my home, navigating the steps down to the basement, and taking away the old water heater. All for the price on the receipt for the new water heater. What Mr. Simpson charges for is the installation of the new water heater and the peace of mind that comes with having a master plumber do a masterful job. Articulate, polite, and efficient, he made me aware of everything he was doing every step of the way. He is obviously a person who takes pride in his work. Mr. Simpson's work comes with a guarantee to amend any problem that arises. A guarantee I have not needed to avail myself of, but appreciate nonetheless. I am thoroughly satisfied with the job he did, and recommend him as an honest tradesman."
