How to Detect a Slab Leak Before it's Too Late

Nov 18

A slab leak is a serious issue that can lead to extensive damage to your home if left undetected. But how can you tell if you have a slab leak? And how long can a slab leak go undetected before it becomes a major problem?

Well, first of all, a slab leak is a type of plumbing issue that occurs when the water supply line leaks underneath your home's concrete foundation. This can lead to serious damage to your home if left undetected, as it can cause extensive water damage to your floors, walls, and even furniture.

One of the easiest ways to determine whether or not you have a slab leak is to call your trusted slab leak detection Scottsdale, AZ. They will be able to use special equipment to detect any leaks that might be occurring in your home, and they can typically do this within just a few hours.

5 Signs You Have a Slab Leak 

A slab leak is a water leak that occurs in the pipes beneath your home’s foundation. Slab leaks can be caused by a number of factors, including corrosion, poor water pressure, or settling shifting soil. Because they occur underground, they can be difficult to detect—but there are some telltale signs. If you think you may have a slab leak, look out for the following five red flags.


  1. Unexplained increases in your water bill.

If you suddenly find yourself paying significantly more for water than you used to, it could be because water is leaking from your pipes and running up your bill. Check for leaks in other areas of your home, such as dripping faucets or toilets that run constantly, and if you can't find any leaks there, it's time to call a professional to check for a slab leak.


  1. The sound of running water when all appliances are turned off.

This is one of the most common signs of a slab leak. If you hear running water even when all water-using appliances in your home are turned off, it's likely that there is water leaking somewhere in your plumbing system. 


  1. Water stains on your ceiling or walls.

If you see water stains on your ceilings or walls, it's important to have them checked out right away as they could be indicative of a serious problem with your plumbing. 


  1. Warm spots on your floor.

Slab leaks can sometimes be detected by feeling for warm spots on your floors—particularly if they are made of concrete, which conducts heat well. If you suspect you have a slab leak, put your hand on the floor and see if you can feel any warmth emanating from it; if so, there's a good chance you have a leak. 


  1. Mold or mildew growth in strange places.

Because slab leaks often result in excess moisture seeping into your home, they can also lead to mold or mildew growth in unusual places—such as on walls or ceilings that don't typically retain moisture. If you see mold or mildew growing in an unexpected spot, it's worth investigating to see if there might be a hidden leak causing the problem. 


Slab leaks can be serious business—so if you think you may have one, it's important to act fast and call a professional slab leak detection Scottsdale, AZ to investigate further and make any necessary repairs. Don't ignore the early warning signs; doing so could cause extensive damage to your home and end up costing you thousands of dollars down the line!
