"The Hague Team are experts. Would hire them again. Evaluated my need in 20 minutes or less, then set up a new Water softener install for the next morning. New WS installed in 2.5 hours and Hague loaded the solar salt, and explained every procedure. They help me with making Notes for my reference guide."

"Have a whole home water filter (Aquasana) that was already installed. Was happy to find an outfit that was comfortable working with a system they didn't install. I was really impressed with Hague. Herminio arrived right on time and quickly understood what he had to do. He quickly and carefully got the new water softening tanks primed, flushed, and installed. He took care to check for leaks. Will definitely hire Hague again."

"James Matthews was the John C. Flood plumber that responded to my call for water leakage from the kitchen faucet. He quickly located the source of the water leak and repaired it quickly. The cold water supply line valve had locked up and couldn't be turned off, so James quickly replaced the old dial valve with a 1/4 turn valve (which had already been done for the supply lines for the dishwater and hot water). In and out in quick order and cleaned up all debris. Very personable, too."
