License details

"Based in" is the city and county of the address on the business's license record.

What this license covers

• Drilling / construction: licensed to bore, case, complete, and plug water wells.
• Pump installation: licensed to install, repair, and replace well pumps, pressure tanks, and the piping between the well and the building.
• Geothermal loops: also licensed to bore the open- or closed-loop wells that serve a ground-source heat pump.
• Hydrofracturing: licensed to hydrofracture a low-yield well, pressurizing the bedrock to open water-bearing fractures, which can be cheaper than drilling deeper or drilling again.
• Cleaning / disinfection: licensed to chlorinate, clean, and redevelop an existing well, the usual response to a bacteria result or a well that has lost yield to buildup.
• Deepening: licensed to deepen an existing well rather than drill a new one, an option when a well runs dry or the water table drops.
