Slab leak water damage

A slab leak is a pressurized water line leaking under or inside the concrete slab. The plumber finds and repairs or reroutes the line; the restoration company dries the flooring, baseboards and wall bottoms that water has soaked from below.

How the job runs

  1. 1Leak locationA plumber uses acoustic and thermal tools to find the leak, then repairs it through the slab or reroutes the line overhead.
  2. 2Moisture mappingThe restoration technician maps how far water spread through pad, tack strip and wall bottoms.
  3. 3Remove and dryWet pad, baseboards and sometimes the lower drywall are removed; drying equipment runs until the slab and walls read dry.

Most homes in the Phoenix metro are built on slabs, with supply lines running under or through the concrete. Hard water, soil movement and the age of copper lines in older neighborhoods all play a part. Water from a slab leak often shows up as warm spots, wet carpet edges or a surprising water bill.

Because water comes up from below, it saturates pad and the bottom of walls quietly. Drying a slab and the materials on top takes longer than a surface spill, and tile may need to come up.

What affects the cost

Every loss is different, so honest pricing starts with an on-site assessment. These are the factors that move the number.

  • Whether the plumber opened the slab or rerouted
  • Number of rooms and walls affected

  • You see water coming up through grout or cracks
  • The meter keeps moving after you shut off the main

FAQ

Slab leak water damage: common questions

Are slab leaks common in Arizona?

They're a frequent call in the Valley because so many homes sit on slabs with lines under the concrete. Hard water and older copper lines are common contributing factors.

Does insurance cover slab leaks?

Many policies cover access to the leak and the resulting water damage, but not the pipe repair itself. Coverage varies a lot, so read your policy and call your insurer before work starts.
