Slab Leak Repair Service
A hidden leak beneath your home's concrete foundation is one of the most stressful plumbing problems a homeowner can face. Slab leak repair addresses water lines that have started leaking underneath a concrete slab, a common issue in Nairobi properties built with in-slab copper or galvanized piping from the 1980s and 1990s. Left unaddressed, a slab leak can undermine a foundation, feed mold growth, and quietly inflate water bills for months before the damage becomes visible.
What Is a Slab Leak?
A slab leak occurs when a water supply or drain line running beneath a concrete floor develops a crack, corrosion hole, or joint failure. Because these pipes are buried in or under the slab, slab leak repair requires specialized detection equipment rather than simple guesswork — cutting into a floor without pinpointing the exact leak location can cause unnecessary damage and cost.
Signs You Need Slab Leak Repair
Homeowners across Nairobi, from Lavington to Buruburu, typically notice these warning signs before booking slab leak repair:
- Unexplained spikes in your water bill despite no change in usage
- A warm patch on the floor (usually indicates a hot water line leak)
- The sound of running water when all taps and appliances are off
- Cracks appearing in flooring, tiles, or nearby walls
- Damp carpet, warped flooring, or a persistent musty smell
- Low water pressure at fixtures throughout the house
The Slab Leak Repair Process
Our technicians follow a careful, non-destructive-first approach to slab leak repair:
- Leak detection — using acoustic listening devices and thermal imaging to pinpoint the exact leak location without unnecessary drilling.
- Assessment of repair method — depending on severity, we recommend either direct access repair (cutting a small section of slab), pipe re-routing above the slab, or full repiping.
- Water shutoff and controlled access — a minimal section of concrete is cut and removed only where required.
- Pipe repair or replacement — the damaged section is repaired or replaced with corrosion-resistant piping.
- Pressure testing — the repaired line is tested before the slab is patched.
- Slab restoration — concrete is patched and finished to match the surrounding floor.
