FAQs
What is a slab leak and why does it occur in Knoxville homes?
A slab leak is a break or crack in the water lines that run beneath the concrete foundation (slab) of your home. In Knoxville, shifting soil, seasonal temperature changes, aging copper or galvanized pipes, and even minor seismic activity can stress the pipes under your slab. Over time, these stresses can lead to pinhole leaks or full pipe ruptures. Because the leak is hidden below the concrete, water can erode soil, weaken the foundation, and cause significant structural and moisture damage if left unaddressed.
How can I tell if I have a slab leak?
Common signs include: 1) a sudden spike in your water bill, 2) the sound of running water when no fixtures are on, 3) warm or damp spots on flooring, 4) cracks in walls or flooring, 5) mold or mildew odors, and 6) reduced water pressure. In Knoxville’s humid climate, moisture issues can escalate quickly, so if you notice even one of these symptoms, call an emergency plumber immediately.
Why is a slab leak considered an emergency plumbing issue?
Slab leaks can undermine your home’s foundation, leading to costly structural repairs, warp flooring, and foster mold growth that affects indoor air quality. Because water runs continuously, damage can spread rapidly. Quick action limits repair costs and prevents health hazards. That’s why our Knoxville team offers 24/7 emergency response for slab leaks—time is critical.
What should I do while waiting for an emergency plumber to arrive?
1) Shut off your home’s main water valve to stop the flow and minimize flooding. 2) Turn off your water heater to prevent damage from running dry. 3) Move furniture or valuables away from damp areas. 4) Use towels or a wet/dry vacuum to remove standing water if it’s safe. 5) Document any visible damage with photos for insurance claims. Our technicians can guide you by phone until they reach your location, typically within an hour anywhere in the Knoxville area.
How does your Knoxville plumbing team detect and repair slab leaks?
We start with non-invasive electronic leak detection, acoustic listening devices, and infrared thermal imaging to pinpoint the exact leak location without tearing up large sections of flooring. Depending on severity, repair options include: direct access and pipe repair, epoxy pipe lining, or rerouting the water line around the slab. We follow Tennessee building codes, obtain any required permits, and always discuss repair options and pricing upfront.
Will my homeowner’s insurance cover slab leak repairs?
Coverage varies by policy, but many Knoxville homeowners find that insurance will pay for water damage remediation (dry-out, mold removal, floor replacement) though not always for the plumbing repair itself. Keep detailed records, photos, and invoices. Our office staff can help you prepare documentation and work with your adjuster to maximize your claim and reduce out-of-pocket costs.
