CSST Repair and Bonding in Middletown, DE
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 reduces the risk of a lightning-related leak during thunderstorms. A high water table means heavy rain can push groundwater into crawlspaces and basements, making a working sump pump important.

Black Iron Pipe Repair in Middletown, DE
Many older homes in Middletown, DE utilize black iron pipes for gas lines. While durable, these pipes can corrode over time, especially at joints, leading to leaks. Our team is skilled in repairing and replacing sections of black iron pipe, ensuring secure, threaded connections and applying appropriate pipe sealant for a leak-free system. We also check for proper grounding and bonding to prevent electrolysis.

Pool Heater, Fire Pit and BBQ Lines in Middletown, DE

Our specialists in Middletown are trained to repair or replace damaged CSST, making sure all connections are properly seated and sealed with approved fittings and that the system is correctly bonded and grounded according to manufacturer specifications and local codes.

Natural Gas Leak Detection & Repair in Middletown
Detecting a natural gas leak requires specialized equipment and expertise.
