Leak Detection

Some leaks announce themselves with a puddle. The worst ones don't — they quietly rot drywall, swell subfloors, and double your water bill before you notice. We find hidden leaks without tearing your house apart guessing.

What we handle

• Slab leaks under concrete foundations
• In-wall leaks inside finished walls and ceilings
• Underground yard leaks between the meter and the house
• Supply line leaks — pinhole copper, PEX fitting failures, poly-b issues
• Drain line leaks that only show when a specific fixture is used
• Water heater and toilet leaks that look like condensation
• Irrigation and hose bib leaks that spike the summer bill
• Pool and equipment leaks on the plumbing side

Signs you need leak detection

• An unexplained jump in your water bill
• A meter that keeps spinning when nothing is running
• Warm spots on the floor (hot-side slab leak)
• Damp drywall, bubbling paint, or stains on the ceiling
• A mildew smell in a room that shouldn't have one
• Low water pressure that came on gradually
• Cracks in slab or foundation that weren't there last year

How we do it

1. Start with the meter — we verify there's actually a leak and narrow down whether it's supply side or irrigation side
2. Isolate the system. Shut off zones one at a time to cut the search area down to a room or a run
3. Use the right tool: acoustic listening equipment for pressurized leaks, thermal imaging for hot-water leaks behind finishes, tracer gas for slab and yard lines
4. Mark the location precisely — a four-inch access cut instead of a four-foot hole
5. Give you a written repair estimate with options. Reroute, spot repair, or repipe a section — you decide once you see the data

Residential, commercial, or new construction

Most leak detection is residential — finished homes where tearing into walls is expensive. Commercial buildings call us for slab leaks and between-tenant wall leaks that insurance wants documented. On new construction, pressure testing during rough-in catches issues before the drywall goes up, which is a much better day for everyone.

Why call Prestige

Finding the leak is half the job — fixing it without turning your living room into a construction site is the other half. We do both. Licensed and insured, upfront on pricing, and we put our findings in writing for your records and your insurance company. If we can't locate it, you don't pay a locate fee. Call for a free estimate.
