"Danny, from HL Bowman, quickly understood the scope of the installation and used his expertise to make the installation seamless. As a result, the filtration system he installed is now operating perfectly to remove particulates greater the 5 microns from our well water. I would highly recommend HL Bowman for your plumbing needs. "

"We decided not to go tankless but E&R did a great job installing a new 50 gal Rheem heater. Very quick and clean install. I will use them again in the future."

"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!"

"Would hire them in the future if I have a problem. Arrived right on time. The plumber was courteous, did a great job. I can't say if the cost was great because I have no idea what the cost of installing a copper water line to a refrigerator costs. It was more then I thought it would be, but could be what other plumbers charge."
