A slab leak occurs when a water line beneath your home’s concrete foundation develops a leak due to corrosion, shifting soil, aging pipes, or high water pressure. Homes throughout North County San Diego—especially in Vista, Oceanside, and San Marcos—are commonly built on slab foundations, making early detection critical.
Unresolved slab leaks can cause:
• Foundation damage
• Mold and mildew growth
• Cracked or warped flooring
• High water bills
• Loss of water pressure

Homeowners in Carlsbad, Encinitas, and surrounding coastal areas often experience slab leaks due to soil movement and corrosion.
Common warning signs include:
• Sudden increases in water bills
• Warm spots on floors
• Sound of running water when fixtures are off
• Damp carpet or tile
• Cracks in walls or flooring
• Musty odors
• Reduced water pressure
