Water Heater Installation
We provide professional water heater installation and repair services for residential and commercial properties in Pasadena and surrounding areas. Our technicians diagnose performance issues and recommend energy-efficient replacements when needed. With expertise in both traditional tank systems and modern tankless models, we ensure reliable hot water supply while optimizing energy efficiency and system longevity.
Backflow Testing
Our licensed backflow prevention specialists conduct comprehensive testing and installation to protect water systems from contamination. We serve commercial and industrial clients across Houston with code-compliant solutions. Using state-certified equipment, we identify cross-connection risks and implement appropriate prevention measures. Annual testing services help businesses maintain regulatory compliance and ensure public water safety.
PEX Re-piping
We specialize in PEX re-piping solutions for residential and commercial properties experiencing pipe corrosion or leaks. Our minimally invasive installation method reduces property disruption while providing durable, flexible piping systems.
