Leak Detection
& Repair
Professional leak detection using advanced technology to locate hidden leaks quickly and accurately — without unnecessary damage to your home.
Find Hidden Leaks Before They Cause Major Damage
Hidden leaks can silently waste thousands of gallons of water, promote mold growth, weaken structural framing, and drive up your utility bills — all before you even notice a problem. By the time you see water stains on your ceiling or walls, the damage is often already extensive.
M&M Heating, Cooling, Plumbing & Electrical uses advanced leak detection equipment — including acoustic listening devices, thermal imaging, and pressure testing — to pinpoint leaks behind walls, under slabs, and underground without tearing apart your home. For nearly 30 years, Front Range homeowners have trusted us to find the problem fast and fix it right.
Common Leak Issues
From slab leaks to hidden pipe failures, our advanced equipment finds the source fast.
Slab Leaks
Leaks beneath your home's concrete foundation can cause shifting, cracking, and extensive water damage. We use specialized equipment to detect them without breaking through your slab.
Hidden Pipe Leaks Behind Walls
Pipes hidden inside walls and ceilings can develop pinhole leaks or joint failures. Our non-invasive detection methods locate the exact spot without unnecessary drywall removal.
High Water Bills
An unexplained spike in your water bill often signals a hidden leak. We perform thorough pressure testing and detection to find the source and stop the waste.
Water Heater Leaks
Leaking water heaters can cause flooding and water damage in basements, utility rooms, and crawl spaces. We identify the source and recommend repair or replacement.
Outdoor & Underground Leaks
Main water lines, irrigation systems, and outdoor plumbing can develop leaks that go unnoticed for months. We locate underground leaks accurately to minimize excavation.

Your Leak Detection Questions Answered
How does professional leak detection work?
We use a combination of advanced technologies including acoustic listening devices that amplify the sound of water escaping pipes, thermal imaging cameras that detect temperature differences caused by moisture, electronic moisture meters, and pressure testing. These tools allow us to locate leaks precisely without invasive exploration.
Do you need to tear up my walls or floors to find a leak?
No. Our non-invasive detection methods are designed to locate leaks through walls, floors, and slabs without any demolition. We pinpoint the exact location first so that any repair work is targeted and minimal. You won't have unnecessary holes in your home.
What is a slab leak and how serious is it?
A slab leak occurs when a water or sewer pipe running beneath your home's concrete foundation develops a crack or hole. Left unaddressed, slab leaks can cause foundation shifting, cracking, mold growth, and significant structural damage. Early detection is critical — if you notice warm spots on your floor, the sound of running water when fixtures are off, or cracks in your foundation, call us right away.
What are common signs of a hidden leak?
Watch for unexplained increases in your water bill, the sound of running water when no fixtures are in use, musty or moldy odors, water stains on walls or ceilings, warped flooring, damp or warm spots on floors, and low water pressure. If you notice any of these signs, it's worth scheduling a professional leak detection inspection.
How much does leak detection cost?
The cost of leak detection depends on the complexity and location of the suspected leak. We provide upfront, transparent pricing before any work begins — no hidden fees or surprise charges. In many cases, the cost of detection saves you thousands in water damage repairs by catching the problem early. Contact us for a free leak assessment.
