The Customer’s Concern: Buckling Floors

When this customer noticed their hardwood floors were buckling, naturally, they immediately feared a slab leak. Slab leaks can cause extensive damage and can be costly to repair. Concerned about the potential for major damage, they reached out to Aaron Services for help.

Understanding Slab Leaks

A slab leak occurs when pipes under the concrete foundation of a home break or crack. This issue is most common in homes without basements, but it can also happen under basement floors. Pipes can leak as they age, or certain piping materials, like blue polybutylene, have been determined to be defective. Slab leaks can lead to significant structural damage and high repair costs because accessing the pipes beneath the concrete is challenging.

Fortunately, homeowners insurance often covers much of the cost associated with repairing a slab leak. While the pipe repair itself may not be covered, the costs of accessing the leak and restoring the area afterward may be. At Aaron Services, we have extensive experience working with insurance companies to keep the process hassle-free for our customers.

Slab Leak Signs: What to Watch For

Recognizing slab leak signs early can save you from extensive damage and expensive repairs. Below are some of the most common indicators that there may be a leak beneath your home’s concrete foundation.

1. Warm or Hot Spots on the Floor

Feeling heat underfoot? This is one of the most common slab leak signs, especially when the leak is from a hot water line. If you notice certain areas of your tile, hardwood, or laminate floor feeling warmer than others, it’s time to schedule a professional inspection.

2. Buckling or Warped Flooring

When water accumulates under your flooring, it can cause the materials to shift, swell, or buckle. Warped floorboards, lifted tiles, or soft spots in the floor are all serious slab leak signs. Left unchecked, the damage may spread to walls, baseboards, or cabinets.

3. Wet or Damp Spots on the Floor

Persistent dampness or discoloration on your floor with no known source often indicates a hidden leak below the slab. If these wet spots continue to appear or reappear after drying, it’s a strong sign that you may be dealing with a slab leak.

4. Sudden Increase in Your Water Bill

A spike in your water bill—without an obvious change in water usage—can signal a leak somewhere in your plumbing system. If other leak sources have been ruled out, consider slab leak detection as your next step.

5. Sounds of Running Water When Fixtures Are Off

If you can hear water running or hissing when no taps or appliances are in use, it might be due to water escaping from a slab leak. These sounds often go unnoticed until they become more frequent or louder.

Signs It Might Not Be a Slab Leak

Not every floor issue is caused by plumbing. Here are a few conditions that mimic slab leak signs:

  • Symptoms only appear after rain: This may indicate foundation seepage or improper drainage, rather than a plumbing-related issue.
  • Condensation or leaks from appliances: Water from AC units, refrigerators, or water heaters can cause floor moisture and staining, similar to a slab leak.

If you’re noticing any of these slab leak signs—or you’re unsure whether you’re dealing with a plumbing issue—schedule an expert evaluation with Aaron Plumbing. Our team uses non-invasive slab leak detection tools to accurately diagnose the problem and help protect your home.

Aaron Services to the Rescue

Our experienced technician arrived promptly and conducted a thorough inspection of the area. Armed with advanced leak detection equipment, he carefully examined the entire space to identify the source of the problem. Using our state-of-the-art leak detection tools, our technician meticulously checked for leaks. Instead of finding a costly slab leak, he discovered that the source of the problem was actually in the wall, hidden behind the drywall. This meant a less involved and much more affordable repair for the customer.

The Real Source of the Problem

Upon further inspection, we found that the issue was a leaking section of the drainpipe behind the wall. Several small holes in the pipe were causing the water damage, which led to the buckling hardwood floors.

We carefully opened the wall, ensuring minimal damage for a straightforward repair. Inside, we found the leaking drainpipe section and noted several small holes causing the issue. But that wasn’t all we found; there was also evidence of mold, indicating that this slow hidden leak had been causing unseen damage for some time.

Hidden Danger: Mold

It’s a good thing the customer called us when they did. Slow hidden leaks like this can lead to major mold problems over time, which can be costly and hazardous to health. The combination of moisture and darkness can encourage fast mold growth. Early detection and prompt repair are crucial in preventing such issues.

This situation highlights the importance of calling professionals promptly. Slow hidden leaks can lead to significant damage and health hazards if left untreated. At Aaron Services, our timely intervention ensured that the problem was addressed before it could escalate further.

The Repair Process

We replaced the leaking section of the drainpipe with new, high-quality piping. With the repair completed, the area is safe from further water damage. Our customer was thrilled with our quick and reliable service. They sent in a glowing review, expressing their relief and satisfaction with the outcome. They were grateful that what they feared was a major issue turned out to be a manageable and affordable repair.

Aaron Plumbing was awesome. I thought I had a slab leak and when Stevie assessed everything he discovered it was a leak behind the powder room wall. Thanks to Stevie I didn’t have to pay as much on repairs.
