Cole's Drilling LLC is a specialty ground-drilling contractor based in DeRidder, Louisiana with approximately 30 years of operating history. The company holds active membership in the National Ground Water Association (NGWA). Their documented service list includes geothermal drilling, geothermal manifolding, coil tubing insertion for geothermal systems, and earthwork — a scope that extends beyond basic boring offered by generalist drillers to include the loop-field integration work (manifolding and coil insertion) that ties the ground loop to the heat pump system. Cole's also provides water well drilling, well pump service, and well water testing. The firm accepts geothermal work beyond its DeRidder base through nationwide referrals. As a specialty driller with three decades of operating history and NGWA membership, Cole's represents the drilling half of the geothermal installation chain for Beauregard Parish and surrounding parishes in southwest Louisiana.
