"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."

"They were up front with what is wrong. Provided explanation of the quote. Asked permission to get access to places. They explain the reasoning for the cost and the risks if ignored. Pricing was fair. Went above an beyond to solve the water heater issue we had. Even calling in an electrician to help with a fix. They were on-time to early on their scheduled appointments. Excellent customer service."
