Professional Slab Leak Detection
DFW homes sit on shifting clay soil that stresses the copper pipes beneath the slab, making slab leaks common here. MasterTex Plumbing & Drain uses electronic amplification, thermal imaging, and pressure testing to pinpoint slab leaks without tearing up your floors. Once located, we explain your repair options — direct access or reroute — with upfront pricing.
The Slab Leak Detection Difference
Non-Invasive Detection
Electronic and thermal tools find the leak without jackhammering your slab to search.
Foundation Protection
Catching a slab leak early prevents foundation movement, mold, and costly structural repair.
Clear Repair Options
Direct repair, reroute, or re-pipe — we explain the pros, cons, and price of each. A water-line (supply-side) slab leak spot repair is $2,250–$4,550.
Insurance Documentation
