Handling Slab Leaks in Your Home

Slab leaks can be a serious issue if left unchecked. They can cause mildew and molding under carpeted slabs or even cracks in tiles, walls, and flooring. In addition to cosmetic damage, slab leaks can also cause foundation issues due to the accumulation of water underground.

By understanding the causes of these leaks, it will be easier to diagnose them. There are also several indicators to look for when making a determination on whether a slab leak exists. Depending on the size of the leak and the damage caused, repair times may vary.


While causes for slab leaks can vary widely, the most common types involve piping, commercial chemicals, and ground issues.

  • Pipes – The most common piping issues that result in slab leaks are either bad pipes that result from rusting metal pipes that have cracked or poorly assembled pipes due to loose fittings.
  • Commercial Chemicals – When pipes become clogged, one of the easiest solutions is to use commercial grade chemicals to eat through the clog. The downside of this method is that sometimes the chemicals eat through the pipes as well.
  • Ground Issues - Shifting soil or the intrusion of roots can rupture pipes causing a leak.

Slab Leak Presence

If you have ever wondered if you have a slab leak there are several indications to consider. The first and foremost method of detection is simply looking at your water bill for the month and seeing if there are abnormally high charges. If so, you know there is at least some sort of problem. To pinpoint a slab leak look for signs like:

  • Excessive moisture of mildew under carpets that cover a slab.
  • Hearing running water even after all of the faucets in the building have been turned off.
  • Cracking in uncovered slab flooring followed by moisture seepage.
  • Warm patches on the floor when the hot water is running.

Repair Time

Repair time will vary depending on the amount of unseen damage. Smaller repairs can be completed in about a day like sport repairs or epoxy pipe coatings at the site of the leak. Medium to large repairs can take 2-5 days depending on how much slab must be removed.
