Find Hidden Water Leaks Before They Cause Costly Damage
Plumbing problems can interrupt tenants, customers, employees, and daily business. Capital City Plumbing and Leak Detection Services provides responsive commercial diagnostics, repairs, and planned plumbing work with attention to access, shutdowns, approvals, documentation, and the needs of an occupied property.
Professional Detection for Leaks You Cannot See
Hidden leaks are often discovered only after a water bill rises, paint begins to bubble, flooring changes color, or a musty odor appears. Because water can travel away from its source, the wettest visible area is not always where the leak began.
Our technicians evaluate the plumbing system and affected areas using the detection methods best suited to the conditions. Depending on the property and suspected leak, this may include moisture measurements, pressure testing, acoustic listening, and thermal imaging. The goal is to locate the likely source as accurately as possible while limiting unnecessary opening of walls, floors, or ceilings.
Signs You May Need This Service

An unexplained increase in your water bill

Damp, stained, bubbling, or peeling walls and ceilings

How We Locate the Problem
- We discuss the symptoms, affected areas, and recent plumbing history.
- We inspect accessible fixtures, supply lines, and visible plumbing components.
- We test and scan the suspected area with appropriate diagnostic equipment.
- We explain our findings and recommend the next step, including repair options when applicable.
California Code and Permit Considerations
Detection may be completed without altering the plumbing. If access confirms a leaking supply, waste, or drainage line, the resulting repair should use approved materials and joining methods and preserve potable-water protection, drainage performance, access, support, and testing required by the California Plumbing Code.
Opening a finished surface to inspect conditions is different from altering piping. The repair, permit, inspection, and finish-restoration scope should be identified before work proceeds.
