CSST Repair and Bonding in Helena, MT
Corrugated stainless steel tubing is common in newer homes, especially in attics. CSST can be damaged by nails, rodents or lightning, and older yellow jacket CSST needs proper bonding. We repair damaged sections with manufacturer-approved fittings and verify bonding to the electrical system. This lowers the risk of a lightning-related leak during severe storms. Spring snowmelt is the biggest water event of the year in Montana, raising rivers and groundwater and pushing water into basements.

Corroded & Damaged Gas Pipe Replacement in Helena
Over time, ground movement and moisture can cause underground gas lines to corrode or become damaged, along with tree roots and age. Some areas have expansive clay that swells when wet, which can shift foundations and stress buried pipes. We specialize in replacing compromised sections of gas piping, using durable materials like polyethylene (PE) for underground lines or black iron pipe for exposed sections, all installed to current code. Our repairs prevent future leaks and protect the long-term reliability of your gas supply in Helena.
Gas Leak Detection & Repair in Helena
Suspecting a gas leak is a serious concern, and prompt action is crucial. Our technicians use modern gas leak detection equipment, like electronic sniffers and soap solutions, to pinpoint the exact location of a leak in your home in Helena. Once identified, we perform precise repairs, which can involve patching, replacing sections of pipe, or tightening connections, always keeping the highest safety standards and proper pressure testing after the repair.

Gas Leak Detection in Helena
A rotten egg smell, hissing near a line, dead plants over a buried pipe or a gas meter that moves with everything off are common leak signs.

Appliance Connector and Shutoff Repair in Helena
Old flexible connectors, especially uncoated brass ones, can crack and leak. We replace them with new coated stainless connectors sized for the appliance and install easy-to-reach shutoff valves.
