This company has total integrity. I am very pleased with their products, service and honesty. Another company tried to convince me I needed lots of new water equipment when it was actually working quite well. I trust Sterling and have had nothing but 100% positive experiences with them.

Outstanding...honest, very reasonable prices. I would recommend highly using Sterling. Small operation, but they care about you. The work was very professionally fitted, cleaned up beautifully after they were complete.

We're very happy with Sterling and their service! We had gotten a quote from another bigger name water treatment service that was a little hard to swallow, so we found Sterling to get a 2nd opinion. George was super quick and responsive, and they helped us verify what we actually needed, which saved us money. We'll see how the new system holds up but would definitely recommend Sterling if you're looking!
