Commercial Leak Detection & Repair Services in Merced, CA

Plumbing leaks are one of the most common—and most costly—problems in commercial buildings. Even newer copper or plastic piping systems can develop pinhole leaks or loose joints over time. Because most commercial plumbing is hidden behind walls or ceilings, leaks can go undetected for months. That’s where MCM Plumbing comes in.

• Advanced equipment for non-invasive diagnosis
• Licensed A, C-36, and C-34 Commercial Plumbing Contractor

We use industry-leading tools and diagnostic techniques to locate and repair water leaks quickly—before they cause structural damage or drive up your water bill.

Warning Signs of Hidden Plumbing Leaks

Leaks don’t always show themselves with dramatic floods. Here are some subtle signs that your commercial building may have a hidden water leak:

• Unexpected spike in your water bill – A hidden leak can waste hundreds of gallons per month.
• Water stains on ceiling tiles or drywall – Often a telltale sign of a slow leak from above.
• Unusual indoor humidity – Damp air or musty smells can indicate pipe leaks behind walls.
• Low water pressure at fixtures – A leak in a main or lateral line can reduce system performance.

Even without visible signs, we recommend scheduling leak detection every few years for commercial properties. Early intervention can save thousands in water damage and utility costs.

How We Find Commercial Water Leaks

Our commercial leak detection process combines years of plumbing experience with the latest technology. We start with a full inspection to look for obvious signs, then use precision tools to locate the leak:

• Acoustic listening devices – Detect sound changes in pressurized lines
• Thermal imaging – Identify temperature anomalies behind walls or under slabs
• Electronic pipe locators – Pinpoint underground or in-wall lines

Once the leak is found, we’ll make targeted repairs—minimizing the need to cut into walls, ceilings, or flooring.
