Under-slab drain repair fixes damaged or clogged pipes that run beneath a home’s concrete foundation. Repair methods may include leak detection, trenchless pipe lining, or full pipe replacement, depending on the severity of the issue.
Common signs include warm or damp spots on floors, unexplained water bills, gurgling sounds, slow drains, lingering odors, or hairline cracks in tile or concrete. A professional can confirm the leak with camera inspections and pressure tests.
Yes, trenchless methods such as pipe lining or bursting are often effective beneath slabs with minimal disruption. The suitability depends on the pipe material, extent of damage, and available access points.
Common causes include soil movement, corrosion of older metal pipes, root intrusion, mineral buildup, and stress on joints. Improper slope or previous patchwork can also contribute to failures.
Simple spot repairs may take a few hours. Larger repairs requiring pipe lining or replacement may take one to two days, depending on access, drying times, and inspection results.
Not always. Many repairs use existing cleanouts or exterior access. If slab access is necessary, we make small, targeted openings to complete the repair and then restore the area.
Costs vary based on pipe length, material, access, and the method used. Tennessee Standard Plumbing provides upfront estimates after a thorough inspection, so you know the total cost before work begins.
Preventative measures include periodic camera inspections, avoiding the flushing of wipes or grease, using strainers in sinks and showers, and hydro jetting when necessary. Early maintenance keeps pipes clear and extends system life.
