Warm spots on the floor

A leak on a hot water line under the slab warms the floor above it. You may feel a warm patch on tile, often near the kitchen, bathrooms or water heater.

A jump in the water bill

If your bill rises without any change in how you use water, a hidden leak is a likely cause. Compare with the same month last year.

The sound of running water

With every fixture off, listen near the floor. A hiss or rushing sound can be water escaping under the slab.

A meter that keeps moving

Turn off every fixture and watch the meter's small leak indicator. If it moves, water is going somewhere.

Quick slab leak test

  • Turn off every fixture
  • Check the meter leak indicator
  • Wait an hour and check again
  • Feel the floor for warm spots

Damp baseboards or flooring

Water from a slab leak can wick up into baseboards or show as damp carpet or lifting plank flooring with no leak above.

Cracks or loose tiles

New cracks in tile or grout, or tiles that sound hollow, can be a sign of moisture or movement under the floor.

If water is already in the house

This guide is about slab leak signs peoria homeowners should know, but if water is already on the floor or coming through a ceiling, the order of steps is the same everywhere in Peoria: close the main valve, keep people away from wet outlets, take photos of the water and the source, and call for help. The faster water is removed, the more of the house can be dried in place instead of torn out.

What it can cost

Costs connected to slab leak signs peoria homeowners should know depend on how much water got out, how long it sat and which materials were wet. A leak found within an hour and dried the same day is usually a modest bill. The same leak found a week later, after it soaked cabinets, carpet pad and drywall, can cost many times more and may need rebuilding. Ask any provider to explain how the price is set before work starts, and ask whether they can bill your insurer directly if the cause is covered.

Renters and landlords

If you rent in Peoria, report anything related to slab leak signs peoria homeowners should know to your landlord or property manager right away, in writing, with photos. The building is usually the owner's responsibility, while your belongings are covered by renters insurance if you have it. Landlords who act the same day protect the property and keep tenants in place, which almost always costs less than a slow response.

Why Peoria slabs have leaks

Copper lines under a slab sit against concrete and gravel. Every time hot water runs, the pipe expands and contracts slightly, and over years that movement can wear a hole where the pipe touches something hard. Hard water wears the inside at the same time. Homes from the 1980s and 1990s are the most common slab leak calls.

Leak detection

A leak detection specialist uses pressure tests to confirm which line is leaking and acoustic equipment and sometimes thermal cameras to pinpoint where. A good pinpoint means a smaller opening in the floor or a better plan for rerouting.

Repair choices

Spot repairs open the slab right over the leak. Reroutes run a new line through the attic and walls and abandon the old one. Repipes replace all the supply lines. Each has trade-offs in cost, disruption and how likely another leak is.

Drying after the repair

Once the line is fixed, the restoration company dries the slab, the setting bed under tile and anything that wicked up water. Concrete dries slowly, so slab jobs often take longer than leaks above the floor. New flooring should wait until the slab reads dry.

Slab leaks and the water bill

The City of Peoria bills water monthly, and a sudden jump is often the first clue. Keep a few months of bills handy so you can compare. If the use doubled without a new pool fill, guests or a landscaping change, do the meter test the same day.

What to do next

Close the main valve if you suspect an active leak. Call a leak detection plumber to pinpoint it and a restoration company to dry the slab and flooring once the repair is made.
