Service Overview

What Is Commercial Leak Detection?

Quick answer

Commercial leak detection is leak location for properties other than single-family homes, including office buildings, restaurants, retail spaces, gas stations, apartments, HOAs and municipal buildings. It finds hidden leaks in supply lines, drains, sewer lines and building envelopes in complex, multi-unit plumbing systems while keeping disruption to the business as low as possible.

For a business to operate at maximum efficiency, its building and infrastructure have to work properly. Managing and maintaining commercial and municipal properties is a big task, from multi-unit buildings to complex plumbing layouts, making sure water, drain and sewer lines all work the way they should.

Pinpointing leaks in these buildings is a challenge of its own. Plumbing runs through shared walls, ceilings and slabs, and a leak in one area often appears somewhere else. When leaks are not noticed in time, they lead to significant damage and can interrupt your business and your tenants’ routines.

We know how important it is to keep your business running after a plumbing problem. Whether it is an emergency or a routine check, we locate the issue, explain what is going on and tell you the total cost of repair before we begin any repair work, with no hidden or extra fees.

How We Help

Leak Detection Surveys for Commercial and Municipal Properties

Finding leaks early protects your building, your budget and your operations. Here is how professional leak detection helps commercial and municipal owners:

  • Reduce non-revenue water. Locating leaks lowers wasted water and the treatment and pumping costs that come with it.
  • Avoid system contamination. With complex sanitation in commercial and municipal buildings, main line leaks can risk drawing in contaminated groundwater. Finding leaks helps prevent that.
  • Reduce liability. Catching leaks before they damage streets, underground utilities, tenant spaces and more lowers the risk of liability.
  • Limit disruption. Non-destructive detection avoids opening walls, ceilings and floors across occupied spaces to search.

Camera inspection for commercial drains

Rather than digging up a building to find the cause of a recurring clog or drain leak, we inspect the drain line visually with a camera. That identifies the problem faster and helps keep repair costs down. See sewer camera inspection.

High water bill in an apartment building?

Two things usually raise the question of a leak: a bill that keeps climbing and water use that has not changed. Other signs include cracks in the foundation, unpleasant odors and damp flooring or carpet. When you notice unusual changes, a pressure test of the plumbing system can confirm whether water is being lost, and leak detection can find where.

What counts as commercial leak detection?

Any property that is not a single-family residence, including offices, restaurants, retail spaces, gas stations, apartments, HOAs and municipal buildings.

We use non-destructive methods such as thermal imaging, pressure testing and acoustic equipment, and coordinate access around your operations to keep disruption low.

Commercial properties vary widely, so cost depends on the building and the scope. You will know the total cost of repair before any repair work begins.

If usage has not changed, a hidden leak is likely. A pressure test can confirm water loss, and leak detection can locate it, whether in a unit, a riser, under the slab or underground.

Yes. Call (619) 374-8554 any time.

Regular leak detection checks help catch problems before they disrupt your business. Ask us about scheduling them for your property.
