Slab Leak Detection & Repair in Corona, CA
Call Now (951) 387-4879Corona sits on some of the most expansive clay soil in the Inland Empire, and that geology is a direct cause of the city's high slab leak rate. During the rainy season, the clay soil under Corona foundations absorbs water and swells. During the long dry months — June through October — it contracts and shrinks. This constant cycle of expansion and contraction creates movement under the slab that puts stress on the rigid copper supply lines running beneath your foundation. Over years of this cycle, copper joints and fittings fatigue, develop hairline cracks, and eventually start leaking pressurized water into the soil under your home.
But Corona's soil is only half the problem. The hard water from Corona's municipal supply at 15-25 grains per gallon is simultaneously corroding those same copper pipes from the inside out. While the soil is stressing the pipe from the outside, the mineral-rich water is thinning the pipe walls from within. This two-front attack means Corona homes develop slab leaks at a higher rate than cities with either hard water alone or expansive soil alone — it is the combination that makes Corona one of our busiest cities for slab leak work.
South Corona and Corona Hills homes from the 1980s-90s are in the prime window for slab leak failures right now. These homes have copper supply lines that are 30-40 years old — old enough for significant internal corrosion but young enough that many homeowners have never thought about their under-slab plumbing. Sierra Del Oro homes built on hillsides face additional stress from soil creep, where the slow downhill movement of hillside soil puts lateral pressure on the slab and everything underneath it. Older homes inside the Grand Boulevard circle have even older copper that may be on its second or third failure.
We detect slab leaks using electronic amplification, thermal imaging, and pressure isolation testing — all non-invasive methods that locate the leak through the concrete without tearing up your floor. Once we know the location, we present repair options with firm pricing. For conventional slab foundations, both direct access (jackhammer) and reroute through walls or attic are viable. For post-tension slabs in newer Corona developments, reroute is the only safe option. If you have had multiple slab leaks, a full water line reroute through the attic eliminates the problem permanently. After any slab leak repair, we strongly recommend installing a whole-house water softener to protect the remaining or new pipes from the hard water corrosion that caused the leak in the first place.
If your slab leak is actively causing flooding or significant water damage, call our 24/7 emergency line for immediate response.

Why Corona Homeowners Choose Us for Slab Leak Detection & Repair
Expansive Soil + Hard Water Expertise
We understand how Corona's clay soil movement and hard water work together to cause slab leaks at a higher rate than either factor alone. Our repair recommendations account for both forces.
Every Corona Neighborhood
We handle slab leaks throughout Corona — from 1890s homes inside the circle to 2000s developments in Dos Lagos. We know the construction patterns, foundation types, and soil conditions in every area.
Prevention-Focused
After repairing the immediate leak, we discuss strategies to prevent the next one — water softener installation, pressure regulation, and rerouting remaining at-risk lines before they fail.
Insurance Documentation Included
We provide complete photographic documentation of the detection, leak location, resulting damage, and completed repair to support your insurance claim.
Our Slab Leak Detection & Repair Process
Non-Invasive Leak Detection
We use electronic amplification equipment to detect the sound of pressurized water escaping under the slab, and thermal imaging cameras to identify temperature anomalies on the floor surface. In Corona, where expansive soil movement can cause leaks at joints and fittings rather than just pinhole corrosion, the detection profile is sometimes different — we listen for distinctive patterns that indicate a joint separation versus a pipe wall failure.
Pressure Isolation Test
We isolate the hot and cold supply lines and test each separately under pressure. This confirms which line is leaking, verifies our detection findings, and reveals whether there are single or multiple points of failure. In Corona homes where both soil stress and internal corrosion are factors, finding multiple pressure drops is not uncommon.
Repair Options and Upfront Pricing
We explain your repair options with firm pricing: direct access through the slab (for conventional foundations), single-line reroute through walls or attic, or full water line reroute for homes with multiple leaks. We also discuss prevention — a water softener to address the hard water corrosion, and whether remaining under-slab lines should be proactively rerouted before they fail.
Complete the Repair and Pressure Test
We perform the chosen repair and pressure-test the entire system to verify the fix holds. For direct access repairs, we patch the concrete and restore the affected area. For reroutes, we run new supply lines through walls or attic space with minimal disruption to your home.
Cleanup and Insurance Documentation
We clean up completely and provide detailed documentation with photographs for your insurance claim. Most homeowner's policies cover the resulting water damage (flooring, drywall, mold) though the plumbing repair itself is typically the homeowner's responsibility. We recommend contacting your insurer as soon as a slab leak is confirmed.
Frequently Asked Questions
Common signs include: an unexplained spike in your water bill (even a modest increase can indicate a slow leak), the sound of running water when all fixtures are turned off, warm or hot spots on tile or concrete floors (indicating a hot-side leak), damp or warped flooring, cracks appearing in walls or the foundation, or a musty smell near floor level. In Corona, where expansive soil already puts stress on foundations, slab leak damage compounds particularly quickly because the escaping water further saturates and swells the clay soil under your home, increasing foundation movement. Call us immediately if you notice any of these signs.
