Expert Water Leak Detection & Repair
A hidden leak can quietly run up thousands of dollars in water bills, rot structural framing, and shut a facility down before anyone notices a stain on the ceiling. OnPoint Mechanical’s leak detection team uses acoustic listening equipment, thermal imaging, tracer gas, and line pressure testing to pinpoint the exact source of a leak without tearing your building apart.
From slab leaks and pinhole copper failures to pressurized supply lines, irrigation mains, and concealed drain leaks, our licensed plumbers (NPL 44659) handle the full scope of commercial leak work — detection, repair, re-piping, and coordination with your roofer, remediation contractor, or insurance adjuster. We respond 24/7/365 and typically arrive on-site within 4 hours of your call.

Our license (NPL 44659) covers the full scope of plumbing work in Texas.
Do you provide drain cleaning and sewer services?
Yes. We offer professional drain cleaning using cable machines, hydro-jetting, and camera inspection technology to clear blockages and diagnose sewer line conditions. For damaged sewer lines, we provide both traditional excavation repair and trenchless lining solutions.
How do you handle plumbing in occupied buildings?
Our plumbers are experienced working in occupied commercial buildings where tenant disruption must be minimized. We schedule work during off-hours when possible, protect finished surfaces, and communicate proactively with building management about water shutdowns and access requirements.
Do you install and service commercial water heaters?
Yes. We install, repair, and maintain all types of commercial water heaters including tank-style, tankless, heat pump, and indirect-fired units. We handle gas, electric, and solar-assisted systems sized to your facility’s hot water demand.
Is backflow testing required for commercial properties?
