Water Leak Detection in Ontario

Hearing a drip you can’t locate, or watching your water bill climb for no obvious reason? In Ontario’s older tract neighborhoods and newer developments alike, a hidden leak behind drywall or under a slab rarely announces itself with a puddle. It shows up as a warped baseboard, a warm spot on the floor, or a meter that keeps spinning after every fixture is shut off. We answer 24/7 and bring the equipment needed to find the source without tearing the house apart first.

Why Ontario Properties See Leak Detection Issues

Ontario sits in the Inland Empire, where summer ground temperatures and the region’s expansive clay soils put real stress on buried plumbing. That soil swells and contracts with the seasonal moisture swings common to San Bernardino County, and over years that movement shifts and stresses the copper or galvanized lines running under slab-on-grade foundations, a construction style used heavily in the tract homes built across Ontario from the 1960s through the 1980s. Add the mineral-heavy water typical of this part of the Inland Empire, and pinhole leaks in older copper supply lines become a recurring call for us. Newer construction isn’t immune either: PEX manifolds and tankless water heater installations can develop slow leaks at fittings that go unnoticed until a ceiling stain or a spike in the water bill gives it away.

Our Water Leak Detection Process in Ontario

We start by ruling out the obvious: toilet flappers, irrigation valves, and water heater connections, since these account for a good share of the “mystery leak” calls we get in Ontario’s residential neighborhoods. If the source isn’t visible, we move to acoustic listening equipment that picks up the sound of pressurized water escaping through a pipe, which works especially well on the concrete slab foundations common across the city. For slab leak detection specifically, we pair acoustic data with thermal imaging to spot the temperature differential a leak creates in the flooring above it, then confirm with moisture meters before anyone cuts into drywall or flooring. This matters in Ontario because so much of the housing stock is single-story slab construction, where a leak under the kitchen or a bathroom can travel laterally under the concrete before it ever surfaces, making guesswork expensive and destructive if you skip proper detection.

Equipment & Methods We Use for Leak Detection

Our technicians carry acoustic leak detectors, infrared thermal cameras, and moisture meters calibrated for both plaster and modern drywall assemblies, since Ontario has a mix of both depending on the decade a home was built. For slab leaks, we also use tracer gas detection when acoustic readings are inconclusive, which happens more often than homeowners expect on slabs poured over the clay-heavy soils found through much of the city. All of our water-related diagnostic and drying work follows IICRC S500 standards, and our technicians hold WRT and ASD certifications, so the detection process lines up with what most insurance carriers expect to see documented if the leak turns into a claim.

Local note

One thing that trips up a lot of DIY leak-hunting in Ontario: irrigation lines for front and back yard sprinkler systems often run close to the same trenches as household supply lines in homes built during the city’s major growth decades. A leak that looks like it’s coming from inside the house can actually be an irrigation line failure just outside the foundation, and vice versa. We test both systems separately before confirming a diagnosis, because treating an irrigation leak as a structural plumbing leak (or the reverse) wastes time and, in slab homes, can mean cutting into the wrong section of concrete.

If you’re dealing with a water bill that doesn’t add up, a damp spot that won’t dry, or a slab that’s warm in one spot and not another, call Dry County Restoration at (951) 667-9910. We’re licensed (#1083555) and carry the certifications adjusters look for, and we document every step of the detection process so you have a clear record whether the leak turns into a repair, a drying job, or an insurance claim.
