Who we help

Leak detection for realtors and escrow

A leak that turns up during an inspection period is a negotiation with a deadline. What you need is a location, in writing, before the deadline — not a theory.

What you actually need from us

A location, a document, and a straight answer about timing

Three things, in that order.

A leak that is merely suspected stalls a transaction. A leak that has been located — this line, this point, this is what putting it right involves — can be scoped, negotiated and closed around. The whole value of an instrumented locate in a deal is that it converts an open question into a known quantity.

So we do three things for a transaction. We locate the leak, rather than pointing at the damage. We write it up in language that can be forwarded to a client, the other side and a lender without translation. And we tell you honestly whether we can do it inside your inspection period, because a hopeful yes that slips is worse for you than an early no.

We report what the equipment shows, in the direction it points. If the property turns out not to have a leak, that is the finding and it goes in writing the same way. We have no interest in which way a deal goes.

On a listing

Where leaks show up in transactions

The pool on a vacant listing

An auto-fill will hide a loss indefinitely, so the level looks perfect right up to the day the new owner closes the valve. Closing the auto-fill and running a bucket test is the simplest way to de-risk a listing with a pool.

The service line

The buried run from the meter to the house belongs to the property. A leak on it shows on usage long before it shows on the surface, and the surface sign can be far from the fault.

Water main leaks →

Under the slab

A warm spot, damp flooring at a wall, or a meter that will not settle. A post-tension slab must not be cut without proper assessment, which is why the locate has to be precise before anyone quotes a repair.

How we work a deal

Built around your deadline

  1. Send the deadline, not the closing date

    The inspection deadline is what everything works back from, and we will tell you straight away whether it fits. We do not publish arrival windows, so you get a real answer on the phone instead of a slogan.

  2. One message settles access

    Who lets us in, whether the water can be shut off for a pressure test, and whether the pool equipment can be run. Those three answers decide what can be tested on the day.

  3. We test, then we locate

    Pressure, sound, dye, thermal imaging and line tracing, in whichever combination this particular property calls for.

  4. Findings in writing, same language for everyone

    What was tested, what was found, where it is, and what the repair involves. One document, forwardable as it stands.

  5. Repair, or just the locate

    Most leaks we locate we can also repair. If the work is better done after close or by somebody else, the locate stands on its own.

Know the pipe before you list

What build era tells you about a house

You already read houses by age. This is the plumbing version of the same instinct. In Arcadia, 67 percent of the housing predates 1980; in the Encanto and Willo area it is 75 percent, and in Maryvale 62 percent. Under that stock the supply is usually copper with galvanised steel at the older end, and it tends to fail where a line was bent or where it rubs — which means the leak is rarely where the wet carpet is.

The growth end of the metro is the mirror image. In Buckeye 89 percent of housing has gone up since 2000, in Laveen 86 percent and in Gilbert 59 percent. That is PEX and newer copper, which rarely fails along a run and usually fails at a fitting or a manifold. Newer houses are not leak-proof; they simply hide their leaks in different places.

Housing figures: U.S. Census Bureau, American Community Survey 5-year estimates (2023).

Straight answers

Questions from agents

Can you get out before my inspection deadline?

Tell us the date and we will give you a straight answer rather than an optimistic one. We do not publish arrival windows because the honest answer depends on the week.

Is this the same as a home inspection?

No, and it is not a substitute for one. A home inspection is a broad visual survey; a leak locate is a narrow instrumented test of the water systems, using pressure, sound, dye and thermal imaging.

Whose side are you on?

Neither. We report what the equipment shows, in the direction it points, and the document reads the same whether the buyer or the seller instructed us.

The listing is vacant with a pool. What would you suggest first?

Close the auto-fill and run the bucket test, before anybody drives anywhere. An auto-fill keeps a leaking pool at a perfect level, which is exactly what makes a vacant listing misleading.

Can you give my client something to negotiate with?

We can give you facts: what was tested, where the leak is and what the repair involves. What anyone does with those in a negotiation is not our business and we stay out of it.

Do you work with escrow and title timelines?

Routinely. Give us the deadline that matters and one contact for access, and we work backwards from it.

Send us the address and the deadline

One line about what the property is doing, the inspection deadline and who handles access is enough to start.

On the clock?

Call or text the address and the deadline. You will get a straight answer about what can be tested and when.
