Slab leaks are hidden, but the damage they cause is not
Peninsula homes built on slab foundations are at risk
Many Bay Area homes, particularly those built from the 1950s through the 1980s, sit on concrete slab foundations with water supply and drain lines running through or beneath the concrete. Over time, these pipes can corrode, shift, or develop pinhole leaks. Because the leak is hidden under your foundation, it often goes undetected for weeks or months, quietly saturating the soil, undermining the slab, and damaging your flooring from below.
We find the leak without tearing up your floor
Our technicians use electronic leak detection equipment, including acoustic listening devices and thermal imaging, to pinpoint the exact location of the leak beneath your slab. This precision means we only need to access a small, targeted area rather than jackhammering large sections of your floor.
Multiple repair options, tailored to your situation
Not every slab leak requires the same fix. Depending on the location, severity, and age of your plumbing, we may recommend a direct repair, a reroute through walls or ceilings, or in some cases, an epoxy lining. We explain each option clearly so you can make an informed decision.
What to expect before, during, and after a slab leak repair
Before
A Caccia technician arrives with electronic leak detection equipment and systematically scans the affected area to pinpoint the leak’s location. We confirm the source, explain the repair options, and provide upfront pricing.
During
Depending on the repair method, we either open a targeted section of the slab to access the damaged pipe, reroute the line through an alternative path, or apply an internal lining. We work carefully to protect your flooring and minimize the footprint of the repair.
After
Once the repair is complete, we test the system for pressure and confirm the leak is resolved. We clean up the work area and discuss any follow-up needs, such as flooring restoration or a whole-home plumbing evaluation if the leak suggests broader pipe deterioration.
6 Signs You May Have a Slab Leak
Unexplained Increase in Your Water Bill
A sudden spike in water usage with no change in your habits is one of the earliest indicators of a hidden leak.
Warm Spots on Floor
If a section of your floor feels noticeably warmer than the surrounding area, a hot water line beneath the slab may be leaking.
Sound of Running Water
If you can hear water flowing through pipes even when all fixtures and appliances are off, water is going somewhere it should not be.
Cracks in Your Foundation or Walls
Water saturating the soil beneath your foundation can cause the slab to shift, leading to visible cracks in your floors, walls, or foundation.
Damp or Warped Flooring
Moisture seeping up through the slab can cause carpet to feel damp, hardwood to warp, or tile to loosen without any visible water source.
Mold or Mildew Smell
A persistent musty odor, especially near the floor, can indicate moisture trapped beneath your slab, creating ideal conditions for mold growth.
