What are the Causes of a Slab Leak?

May 20, 2020 | Blog

Having a slab leak can burn a hole in your wallet and cause massive issues with your home. That is why slab leak detection is very important to keep the situation from becoming worse and costing more money. Here are a few of the signs and causes of a slab leak in your home.

Signs You Have a Slab Leak

  • Unusually High Water Bills – Do you see a drastic increase in your water bill, but you’re using the same amount you normally do? This could be a sign you have a leak somewhere.
  • Wet Floor – The next thing you should look for is damp carpets or warped wooden floors that you can’t explain where the water came from. Water from a slab leak can collect and cause damage to flooring.
  • Mold and Mildew – If you can’t see any visual signs of a leak, check for the smell of mold. Mold can be a sign of water damage in places you can’t see, like in your walls.

What are the causes of slab leaks?

Pressure

One of the biggest reasons for a pipe to crack is because of pressure from the ground. Pressure can cause soil to shift and move the house slightly. This can be the result of a number of things – poor construction, soil erosion or earthquakes, to name a few. While we probably won’t be seeing any earthquakes in San Antonio or Boerne anytime soon, pressure can still affect your slab.

Abrasion

Pipes are subject to expand and contract due to the flow of hot and cold water. The running water also causes the pipes to rattle. Over time, pipes wear down due to the constant friction against concrete and gravel. As the metal of the pipes get thinner and thinner, it eventually causes a leak. Hot water pipes are more likely to break because the expansion causes more abrasion than cold water contracting.

Corrosion

Hot water doesn’t only contribute to the abrasion of the pipes but the corrosion of them, as well. Cold water can also cause corrosion, but the heat of the water and the metal of the pipes have a bigger reaction. This is more common to happen to older houses compared to more modern homes. The types of metal that are normally used in older homes are often those that can corrode, like copper. Copper may be resistant to corrosion, but it is not impossible for it to happen.

Roberta C.

Very Knowledgeable

I recently had several plumbing leaks repaired and couldn’t be happier with the prompt service I received from Parker and Sons. They are very knowledgeable, friendly, reasonably priced, and do quality work. I would definitely recommend them to my family and everyone. I would trust them to repair any leak in the house.

Stacey C.

Amazing Service!!!

Amazing service!!! Called and came the same day within 2 hrs. Our toilet had to be re-fitted and snaked. They did a beautiful job on the re-fitting and got the large piece of plastic out of the toilet. Will definitely be recommending them to friends and family. Great service, great people, hard to find these days!!!

Shakira C.

Excellent Service!

Excellent Service! We had some work done on our kitchen and Parker and Sons were able to come out to our house and help us with our remodel. Great guys and great service. I would recommend them to anyone needing a plumber service.

Brad B.

Great to Work With

Jim and his guys are great to work with. Had Parker & Sons come out to take a look at an AC unit at one of my rental properties. Unit is in the attic. Had to replace a coil on it and did a great job. Will definitely use again.

Jeff C.

Amazing Staff!

I have referred Parker and Sons to all of my customers and I would not think of referring anybody else. They have been great and very punctual. All of the plumbers and office staff have been amazing!

Miguel B.

Reasonable Prices

I was in good hands today with journeyman plumber Mark Rizley. He remained until all was better than before. He replaced a PRV and improved a mediocre repair recently done by another well known local company. The price remained reasonable despite the extra effort needed for the job. Well done Mark! Parker and Sons will be my first call in the future.

Todd D.

Fantastic Company!

This is a fantastic company with outstanding professionalism, quality of work, and customer service. While their prices are extremely competitive, their work doesn’t feel cheap like some of the companies you can hire of off Craigslist or on a FB yard sale page. This is a reputable company with proven work and licensed, skilled technicians.

Fair Prices & Excellent Work

Have used Parker & Sons 3 different times, once for a huge complex plumbing repair and twice for smaller jobs. Fair prices and excellent work/fast response time every time.
