Signs & Causes of Residential Slab Leaks

As a homeowner, you are never expecting a slab leak to occur. Knowing what signs to look for and the potential causes of slab leaks can aid you in catching an issue early and potentially avoid more costly repairs down the road.

Some signs of a slab leak can include:

Unexpectedly High Water Bills

A sudden increase in water bills without any corresponding increase in water usage can be a sign of an underlying slab leak.

Damp or Wet Flooring

Moisture or water seeping up through the floor, especially in the absence of any spills or visible plumbing issues, is a common sign.

Mold and Mildew Growth

Excess moisture from a slab leak can lead to mold and mildew growth, often seen on walls, floors, or baseboards.

Low Water Pressure

A decrease in water pressure in faucets and fixtures can indicate a water leak, including one beneath the slab.

Warm or Hot Spots on Floors

If there are unexplained warm or hot spots on the floor, it might indicate a hot water line leak under the slab.

Cracks in Walls or Flooring

Slab movement due to water damage can cause cracks in the walls and flooring of your home.

Some of the reasons a slab leak can occur in your home include:


Over time, pipes can corrode, especially in areas with hard water, leading to leaks.


The movement of pipes due to shifting soil, settling, or vibrations from construction can cause pipes to rub against rocks or other pipes, leading to abrasion and eventual leaks.

Water Chemistry

Highly acidic or alkaline water can accelerate pipe corrosion, increasing the likelihood of leaks.

Tree Root Intrusion

Tree roots seeking water can penetrate pipes and cause damage, leading to leaks.

Soil Conditions

Expansive soils that swell and contract with moisture levels can exert pressure on pipes, potentially causing damage and leaks.

High Water Pressure

Excessively high water pressure can strain pipes and cause them to develop leaks over time.

It’s crucial to address slab leaks promptly to prevent further damage to the foundation, structural elements, and home interiors. If any of these signs or causes are suspected, be sure to contact Mammoth Plumbing as soon as possible for a thorough inspection and necessary repairs.

Excellent4.6 Based on 23 reviews from review us onAngel Fultz-SmithAngel Fultz-Smith ★★★★★ Mammoth Plumbing has been my go-to plumber for the past few years. They have solved minor problems related to clogs, sinks, and the water heater, and they also installed the gas line for a stand-alone home generator. Their pricing is competitive and reasonable, and I trust them to be honest when assessing a problem. Jon and his team conduct their business with integrity and transparency, and I have recommended them to friends and clients over the years. They're fantastic and I cannot recommend them enough.Response from the ownerThank you ms. Fultz-smith for the review it's always a pleasure working for such great clients, thanks for the referral.

Highly recommend them. There should be a 6th star.Update. We had some serious under-slab plumbing issues. They were able to accurately diagnose the issue where other companies had failed. They put everything back as it was, and even added some smart clean outs and tie-ins for future plans. The most impressive part was though was how much the hustled to get it all done. They even sent my wife flowers when they learned she had gone into labor. Absolutely amazing.Response from the ownerthank you Mr. bower, we really appreciate your business! JohnJohn ★★★★★ I just wanted to send you a big shout out for great service. Jimmy came out to look into my washing machine waste line which also has my drain from the AC unit and it had been slightly overflowing. I first used a safe drain opener to possibly open the line, but in addition wanted to have it looked at to make sure everything was okay. He did an outstanding job scoping the line and found just a small amount of sediment on the walls. I just wanted to let you know that I will highly recommend your company to anyone needing quality professional plumbing work done!JohnResponse from the ownerThank you so much for your business and your patience, it was a pleasure working for you, I will pass this letter on to jimmy.
