Slab Leak Detection & Repair for Businesses in Castle Rock
Slab leaks can be particularly damaging for commercial buildings, especially those built on concrete slab foundations. Rocky mountain ground makes trenching for sewer and water lines harder, and lines must be buried below the local frost depth. These leaks, often caused by shifting soil or corrosive water, can undermine foundations, lead to mold growth, and cause serious water waste. Our technicians use modern acoustic and thermal imaging equipment to pinpoint slab leaks without invasive demolition. Once located, we provide efficient repair solutions, often involving re-routing or pipe repair, to protect your commercial property and prevent costly structural damage in Castle Rock.
Grease Trap Installation & Cleaning in Castle Rock
Restaurants and food service establishments in Castle Rock rely on working grease traps to prevent fats, oils, and grease (FOG) from entering the sewer system. GFR Plumbing offers expert grease trap installation, repair, and regular cleaning services. We make sure your grease trap is correctly sized for your business's needs and maintained to comply with local FOG regulations, preventing costly blockages and potential fines from the city.
Commercial Water Heaters and Boilers in Castle Rock, CO
Commercial kitchens, gyms and multi-family buildings need large amounts of hot water. We service and install high-input tank water heaters, tankless racks and boiler-fed systems with storage tanks.

Mineral scale can build up in these systems fast, so we offer descaling and flushing on a schedule. We also install mixing valves to deliver safe temperatures at handwashing sinks.
