How We Repair Slab Leaks
You used to have to cut through your home’s slab to resolve a slab leak. Thanks to advancements in modern plumbing, however, we can now employ effective repair methods other than slab cutting.
Instead of cutting through your floor straight to the damaged area, we often rely on plumbing tunneling, which requires no floor entry or interior damage repair. In homes with multiple leaks, plumbing tunneling methods can sometimes save hundreds in repair costs. Tunneling also allows you to remain in your house while repairs are completed.
Signs of a Slab Leak
Catching a slab leak early saves you from extensive repairs, high water bills, and potential structural damage. We want to help you identify the common warning signs of a slab leak so that you know when to give our team at DNA Plumbing Services a call.
Here are some of the most common signs of a slab leak:
- Sudden increase in water bills. A surprisingly high water bill with no change in your household water usage often points to some kind of hidden leak that needs to be professionally addressed. A constant flow of water from a broken pipe under your foundation can add up quickly, and your monthly bill will reflect that.
- Sound of running water. Do you hear water running when all faucets and appliances are turned off? This is one of the most direct indicators of a leak. Listen closely to the floors and walls, especially in quiet parts of your house. The sound might be a faint drip or a constant trickle.
- Warm or hot spots on the floor. A leak in a hot water line will transfer heat to the concrete slab above it. If you notice a warm or hot spot on your floor, especially in a specific area, it likely indicates that a hot water line has a leak directly beneath it.
- Moisture or mildew on floors and carpets. Water from a slab leak seeps up through the foundation. This moisture often causes wet spots on carpets or warped floorboards. You might also notice a musty smell or see mildew and mold growing on the baseboards or carpet.
- Cracks in the foundation or walls. A persistent slab leak can compromise the integrity of your home’s foundation. The constant flow of water shifts the soil beneath the slab, leading to foundation movement. This movement often causes new cracks to appear in your home's foundation, walls, or even the ceiling.
What Happens If You Ignore a Slab Leak?
Ignoring a slab leak can lead to serious and costly consequences for your home. When you allow a leak to continue, the constant flow of water erodes the soil supporting your home’s foundation. This erosion creates voids beneath the concrete slab, causing the foundation to shift and settle unevenly. The structural instability from this movement leads to cracks in the foundation itself, as well as in your walls and ceilings, compromising the integrity of your home. You'll likely see warped flooring, buckled carpets, and a build-up of moisture that encourages the growth of mold and mildew, posing health risks and causing a musty odor throughout your home.
The financial consequences of ignoring a slab leak are also significant. As the leak progresses, your water bills will skyrocket because you're paying for water that's not being used. The water damage alone can ruin flooring, drywall, and personal belongings. Ultimately, what starts as a relatively simple plumbing fix can turn into an expensive, large-scale foundation repair project, so don’t wait to reach out if you think you could be dealing with a slab leak.
What Can Cause Slab Leaks in DFW?
Slab leaks in DFW can happen for a variety of reasons, with some directly related to the region's unique geological and environmental conditions. A major culprit is the expansive clay soil common throughout Texas. This soil type absorbs a large amount of water during wet periods, causing it to swell and put immense pressure on your home’s concrete slab and the pipes underneath. During dry spells, the soil contracts and pulls away, creating voids. This constant cycle of expansion and contraction stresses the pipes, causing them to crack, break, or dislocate at the joints over time.
Corrosion is another significant issue, especially for older homes with deteriorating pipes. The minerals in Texas's hard water and the chemical composition of the surrounding soil can cause a slow, corrosive reaction that eats away at the pipes, creating small pinhole leaks that gradually worsen. Additionally, poor installation practices, such as not properly supporting pipes during construction, can create weak points that are prone to failure under pressure. External factors like high water pressure and abrasion, where pipes rub against the concrete or other materials as they expand and contract with hot water, also contribute to the wear and tear that ultimately causes a slab leak.
We can assist with any necessary pipe repairs or repiping when addressing slab leaks. Call (214) 817-3755 or contact us online to schedule an inspection today.
