Top Pre-Purchase Leak Inspection Services

An independent third-party leak inspection before you close. Catches plumbing problems standard home inspections miss — and gives you leverage if something turns up.

Service overview

A standard home inspection covers a lot of ground in a short time. A good inspector will catch obvious issues — visible leaks, water staining, fixture problems — but a four-hour walk-through isn't designed to detect a slab leak that hasn't surfaced yet, an irrigation system losing water underground, or a hot water line on its way out.

A pre-purchase leak inspection is the deeper look. It's specifically focused on the plumbing — supply lines, slab, irrigation, and water-using fixtures — and it's conducted by a leak detection specialist, not a generalist. For buyers in North Texas, where slab construction and expansive clay soils make plumbing failures common, it's one of the most cost-effective contingency-period inspections you can do.

What's included

A pre-purchase leak inspection from RGC covers:

  • Pressure test of supply lines to confirm the system is holding pressure
  • Acoustic and thermal scan of accessible slab areas for active leaks
  • Visual inspection of fixtures and water-using appliances for signs of past or current leaks
  • Irrigation system pressure check if the property has one
  • Inspection of the hot water heater, supply lines, and visible drain lines
  • Written report with photos, findings, and a recommended scope of any repairs

The report is formatted for use in real estate negotiations — clear language, dated photos, and itemized findings.

Why this matters in North Texas

The same conditions that make slab leaks routine for current homeowners — clay soil, foundation movement, aging mid-century housing stock — also make them a significant risk for buyers. A slab leak discovered the week after closing is the buyer's problem. A slab leak discovered the week before closing is a negotiation point.

We've seen pre-purchase inspections find:

  • Active slab leaks the seller was unaware of
  • Failed pressure regulators creating chronic high-pressure damage
  • Irrigation systems dumping water underground that the seller had absorbed into their water bill for months
  • Failing hot water heaters within months of complete failure

Each of these is something a buyer can negotiate around — *if* they know about it before closing.

Who hires us for this service

  • Home buyers who want a deeper plumbing-specific look than a general home inspection provides
  • Real estate agents representing buyers who want a credible third-party report to support negotiation
  • Listing agents representing sellers who want a clean inspection in hand before going to market
  • Investors doing due diligence on rental or flip properties

How it works

Schedule the inspection during your option period. We arrive at the property at a time that works for you and the listing agent, perform the inspection, and deliver a written report within 24 hours. Most pre-purchase inspections are completed in two to three hours on site.

If something turns up, you have time to act on it. If nothing does, you close with confidence.

Common questions

Questions we get on the phone, answered straight.

If somethings not covered here, call. The phone consult is the same five minutes whether you book a job or not.

How accurate is acoustic leak detection?

Within a few inches on most pressurized supply lines. The acoustic gear picks up the high-frequency sound water makes when it escapes the pipe wall, and we cross-reference the signal across multiple sensor positions. Thermal imaging confirms when hot-water lines are involved.

Will you cut into my walls or floors?

No. The whole point of acoustic detection is that it's non-invasive. We listen through finished surfaces and confirm with thermal — the only thing we cut into is the time you'd have lost guessing.

How long does a leak detection take?

Most jobs wrap up in two hours from the time Ralph arrives, including the walkthrough, acoustic sweep, thermal confirmation, marking the spot, and writing the report. Larger properties or trickier leaks can run longer; you'll know upfront.

Can you find a leak even when the water is off?

No, a leak only makes acoustic noise when water is moving through it. We do most of the work with the system pressurized; if the leak is intermittent, we may run controlled pressurization tests during the visit to bring the signature out.

Do I need to be home for the inspection?

If someone is on-site during the inspection, they must be 18 years of age or older to grant access and walk through what we're seeing. We prefer to have you (or another adult representative) there for the start and the handoff. If no one can be there, we'll work with whoever is coordinating the visit.
