What matters for slab leak repair in Norwalk

Hot-water lines

Hot lines expand and contract with every use and are the most common under-slab failures.

Spot repair vs reroute

One leak in otherwise good pipe may justify a spot repair. Repeated leaks favor rerouting through walls and attic.

Foundation concerns

A long-running leak can wash soil from under the slab, so do not wait once a leak is confirmed.

Warning signs to watch for in Norwalk homes

  • Warm or hot spots on the floor
  • Cracks in tile or flooring
  • Damp carpet or swelling wood floors
  • Sound of running water with nothing on
  • Water meter moving
  • Water heater running more often than usual
