Houston Slab Leak Detection and Repair

Think that you may have a leak under your foundation? You’ve come to the right spot. Wedgeworth Plumbing is the Houston slab leak experts!

What is a Slab Leak?

In the Houston area, many homes are built on a slab of concrete, with the plumbing system running underneath it. 

A slab leak, also called a foundation leak or concrete slab leak, is a water leak in the pipes under the concrete foundation of your home or business. This type of leak can cause significant damage to a building’s structure and lead to the development of mold. It’s important that foundation leaks are repaired as soon as possible by a licensed Houston plumbing professional to prevent further damage.

What Causes Slab Leaks?

Foundation movement

If the foundation shifts, the pipes can move as well, which could cause them to pull apart, crack, or break. Foundation movement can be due to Houston’s unique soil expanding and contracting with the changing weather, extreme flooding in the Houston region in recent years, or poor-quality foundation repairs.

Corroded copper or cast iron pipes

Over time, water and chemicals in and around pipes can cause them to break down or rust. Common causes include the use of water softeners and cleaning solutions. Corrosion can also happen when the water velocity in the pipes is too high, if pipes are sitting in wet soil, and where copper pipes come into contact with the steel rebar in the concrete foundation.

  • Pipes that are broken or cracked by tree roots
  • Poor installation of sewer lines or incoming water lines

What are the Symptoms or Problems of a Houston Slab Leak?

Because Houston slab leaks happen below the foundation of your home or business, you may not notice signs of a leak until water has built up and already caused damage. If you notice any of these things, you may have an under slab leak.

Water bill is unusually high

Unfortunately, this is usually how many home or business owners discover they have a leak in their water supply line. Even a small “pinhole” leak can waste over 10,000 gallons of water in just a month.

Excess water around the foundation

Unfortunately, a sewer line can leak under the foundation for years before being noticed. With the expansive soils in Houston, a sewer leak could cause the soil to swell. You may notice wet flower beds or soggy dirt around the building’s foundation. Over time, all that water can cause the slab to erode.

Structural damage to the building

If enough water is present, Texas’ expansive soil can swell up enough to actually lift a building. When this lifting, or heaving, is due to a water leak, you’ll see the foundation buckle. Cracks in floors or walls, floors that are uneven, or doors dragging on the floor are all signs that there could be a water leak under your building’s concrete slab.

Sound of running water

If you can hear water running through the pipes when there isn’t any water being used, that’s a good sign that there could be a leak.

Damp or warm spots on floor

When there’s a leak under the slab, water can seep up through the concrete and onto your flooring. Wet floors, carpet, or baseboards are all possible signs of a leak. Mildew under your flooring is another indicator. If areas of the floor feel warm or even hot, you could have a hot water line leaking out under your foundation.

Remember, these problems will only get worse with time, so it’s important to call the professionals at Wedgeworth Plumbing as soon as you suspect a slab leak. We’ll find and fix the leak, so you can be sure your home or business is a stable, safe, healthy place to be.

Houston Slab Leak Detection

Before a leak can be fixed, we have to confirm that there is a leak, and find exactly where it’s located. Wedgeworth Plumbing starts investigating a slab leak by visually inspecting your property for the signs listed above. Based on this evidence, we can usually determine whether the source of the leak is more likely to be a sewer pipe or water supply line. Then we can begin the actual testing.

Detecting leaks from a sewer line

To check for sewer line leaks, hydrostatic testing is used. A special ball is placed in the main sewer line and inflated until it’s big enough to plug the line. Then we attempt to fill the entire system with water. After 20 minutes, if the lines can’t be filled or they’ve lost water, there’s a slab leak. Once we’ve confirmed a sewer line leak, we have to figure out where it is. We use a special camera to go into the sewer lines and inspect them visually. We can also perform a leak isolation test, which involves filling different sections of pipe with water to see if it will hold.

Detecting water supply line leaks

A pressure test checks for leaks by checking the water pressure delivered from the main supply at the street and comparing it to the pressure in the lines after the supply from the street is turned off. If the pressure in your home’s water lines drops, there’s a leak somewhere.

After a water supply line leak is confirmed, the location is determined by first checking faucets and toilets for drips and leaks. If there are none found, acoustical listening devices can be used to detect the sound of leaking water under the building.

Wedgeworth Plumbing also recommends slab leak detection in these situations:

  • Before any foundation work is started
  • After foundation repair has been completed
  • Before you buy a home
  • Once a year in areas where foundation cracks are common

Once we’ve discovered where the leak under your slab is located, we can fix it.

Houston Slab Leak Repair

Repairing a slab leak quickly will prevent further damage, which saves you money and hassle. Before your repair is started, it’s a good idea to check with your homeowner’s insurance agent to see if you have coverage for any or all of the work to be done.

Because these types of repairs deal with your home’s foundation and demolition, plumbing, and concrete work is usually required, you should choose a licensed professional. Wedgeworth Plumbing uses high-quality materials, and our technicians have the knowledge and skill to not only fix the leak, but to prevent it from happening again. Before beginning the job, we’ll get any required permits and have all utilities marked if outside excavation is needed. The entire process could take up to a week, and we test the lines when we’re done to make sure the leak has been fixed.

The way we fix your slab leak will depend on the location of the leak and the type of pipe that’s leaking. It may be necessary to directly access the leak through the concrete slab and replace the affected section of pipe. Often, the line can just be re-routed through the walls and attic of your building. In this case, the leaky pipe under the slab is simply closed off. This method allows for water line repair without damage to your floors or breaking through the slab. Tunneling a pipe underneath the slab is another option. A newer way to fix slab leaks is to coat the inside of the pipe with an epoxy to seal up the existing leak and prevent future ones. Wedgeworth Plumbing will evaluate your situation to determine the most cost-effective and least invasive way to repair your slab leak.

I had two other companies come to our home and we were told we had to replace the valve for the faucet, which would involve removing tile. Rex came and was confident and replaced our cartridge and fixed the shower for half the cost of replacing a valve. I highly recommend this company.read more

This was a frustrating project because of the unforeseen issues but Damondrick had a great attitude the entire time and stayed late on a Saturday night to make sure the job got done.

Review of Wedgeworth Plumbing

I live in an old house and the plumbing is a nightmare. We've used Wedgeworth numerous times and they do quality work. Damondrick in particular is personable, knowledgeable, and trustworthy. I have used Wedgeworth for quick fixes and larger piping issues, they're good with both. I would recommend Wedgeworth for all plumbing issues.

Wedgeworth dispatched a plumber, Damondrick, to our house within an hour to respond to a water pipe leak that was dripping onto the ceiling below the leak. Damondrick was a real gentleman while in our home and you can tell he was very focused on doing good job - which he did! We were so satisfied with the whole experience and are very happy the leak is was repaired quickly and without any hassles. By the way, Wedgeworth has helped us two other times and both of those experiences were positive also. Thanks guys for the help!
