We replace old plumbing with new PEX or copper, improving water quality and pressure throughout your whole home. This is a key upgrade for many older homes.

Water Line Replacement in Florissant, MO
A leaking main water line can lead to significant water loss, high bills and foundation damage, which is a serious concern for homes on slab foundations. Our water line replacement services address issues like corroded pipes, leaks or low water pressure. We locate the leak, excavate the area if necessary and replace the damaged section or the entire line with durable PEX or copper piping. We make sure of a secure, leak-free connection from the meter to your home, restoring reliable water flow.
Water Heater Replacement in Florissant
When your water heater is leaking, not heating or providing too little hot water, it is often more economical to replace it than to repair it, especially if it is over 10 years old. We install standard tank water heaters, sized properly for your home's needs and compliant with current energy efficiency standards. Our team handles the safe removal of your old unit and the careful installation of your new one, connecting gas or electric lines and confirming correct venting and pressure relief valve operation for performance and safety.
Well Pump and Pressure Tank Replacement in Florissant, MO
Rural properties rely on well pumps to deliver water, and pump failure means no water at all. Typical signs include pressure that fluctuates, a pump that cycles rapidly or no water at the tap. We replace submersible and jet pumps and waterlogged pressure tanks with correctly sized equipment. Pressure switch settings are adjusted for steady pressure throughout the home.
Tankless Water Heater Replacement in Florissant, MO
Upgrade to endless hot water with a tankless water heater replacement. These units heat water on demand, saving energy and space, which is a great benefit for Florissant homes. We specialize in replacing older tankless units or converting from traditional tank heaters to high-efficiency tankless models from brands like Rinnai and Noritz. Our service includes assessing your home's gas line capacity or electrical service, ensuring proper venting and precise installation to maximize efficiency and longevity.
Gas Line Replacement in Florissant
Old or damaged gas lines pose a serious safety risk and need immediate attention. If you suspect a gas leak or your gas lines show signs of corrosion or age, our licensed plumbers in Florissant can perform safe and code-compliant gas line replacement. We use approved materials like black steel pipe or corrugated stainless steel tubing (CSST) for secure installations, making sure all connections are leak-tested and meet strict safety regulations for your home's protection.
Sewer Line Replacement in Florissant
Persistent sewer backups, foul odors or lush spots in your yard can signal a failing sewer line. Basements are common in many areas, so sump pumps and foundation drainage are an important part of keeping homes dry. We offer complete sewer line replacement using trenchless technology whenever possible, limiting disruption to your landscaping. For more severe damage, traditional excavation is performed with careful attention. We make sure new lines are properly graded, connected and compliant with local Florissant plumbing codes, preventing future blockages and costly repairs.
