How Leak Detection Works

1

Initial Assessment

We review symptoms, check your water bill, and narrow down the likely leak location.

2

Detection Equipment

We use acoustic sensors, thermal cameras, and moisture meters to pinpoint the exact leak location without unnecessary demolition.

3

Leak Confirmed

Once we locate the leak, we explain what's leaking, where it is, and what repair is needed.

4

Repair or Referral

If it's a plumbing leak we can fix, we provide pricing and proceed. If it's a structural or roofing issue, we'll point you to the right specialist.

Frequently Asked Questions

How much does leak detection cost?
Leak detection typically costs $200 to $500 depending on the complexity. If we perform the repair, the detection cost is often included or discounted.
Can you find leaks without tearing up walls?
Yes. We use non-invasive methods like acoustic listening devices, thermal imaging, and moisture meters to locate leaks without unnecessary demolition. We only open walls where the leak is confirmed.
What if the leak is under the slab?
Slab leaks are common in NYC. We use specialized equipment to detect under-slab leaks and can either repair the pipe or reroute plumbing if necessary.
How long does leak detection take?
Most leak detection jobs take 1 to 3 hours depending on the building size and leak complexity. Simple leaks can be found in under an hour.
