Pinpointing Failed Supply Lines Beneath Plano Foundations
A Housing Stock Now Old Enough to Leak
Plano grew in waves and the plumbing shows it. Hunters Glen, Los Rios, and the streets east of Custer Road filled in through the 1970s, while Willow Bend, Deerfield, and the neighborhoods feeding the Legacy West corridor went up across the 1980s and 1990s. Almost all of it sits on a concrete slab with copper supply lines run underneath, and copper of that age is reaching the end of its service life. The Blackland clay below swells after heavy rain along Spring Creek and shrinks through a dry August, working the pipe against the concrete until a pinhole opens, usually on the hot side first, often with no visible water indoors.
The Diagnostic Sequence We Follow
A slab leak rarely announces its exact spot. We begin at the meter, isolate the house, and confirm the loss is genuinely under the foundation rather than in an aging sprinkler zone or the yard line, which is a common mix-up on older west Plano lots. The system is then pressurized and surveyed with acoustic equipment sensitive enough to hear water escaping through several inches of concrete. Line tracing maps the real route of the hot and cold runs, since builder drawings rarely survive decades of remodels, and thermal imaging confirms a hot line break by the warm signature it leaves in tile, wood, or carpet. We mark one spot, not a general area.
Local Conditions We Read Before Recommending a Repair
Casto Leak Detection & Plumbing is based in Richardson, minutes down Central Expressway from most of Plano, and we have worked in this trade for more than twenty years under Texas license M#45508. Homes near Bob Woodruff Park and along the Spring Creek greenbelt sit where soil moisture swings hardest, so those conditions get read rather than ignored. City of Plano water pressure is strong enough that a small under-slab pinhole wastes a surprising volume before it ever shows on a bill. Non-invasive testing protects your flooring, landscaping, and post-tension cables until a repair plan is settled. Call (972) 348-0253 for a same-day or next-day appointment.
