Water supply piping where hidden leaks commonly start

Leak Detection & Repair

Find the leak before you open the wall

A stain on a basement ceiling tells you where water landed, not where it came from. In a house with sixty-year-old supply lines the difference matters, because guessing means opening drywall until you get lucky.

  • Wall, ceiling and under-slab leaks
  • Water bill spikes and running meters
  • Located before anything is opened
  • Repair and patch in one visit

Signs

How hidden leaks announce themselves

Most homeowners notice one of these three weeks before they find any actual water.

The bill jumped

A water bill up noticeably with no change in use is the most common first sign of a leak you cannot see.

The meter moves

Shut off every fixture and watch the meter. If it is still turning, water is going somewhere it should not.

Something feels off

A damp patch on a basement wall, a musty smell in one room, or paint that keeps bubbling in the same place.

Not sure whether it is a leak or something else? Our guide on signs you need a plumber covers what is worth a call.

Why it matters

Why locating it properly saves money

Exploratory holes are expensive

Opening drywall to look for a leak means patching, texturing and painting every guess that was wrong. Locating first means one opening.

Finished basements raise the cost

A lot of Florissant split-levels have finished lower levels. Guessing wrong down there is drywall, trim and flooring, not just a patch.

Small leaks do real damage

A slow leak inside a wall does not flood anything. It rots framing and grows mold quietly for months.

And it settles insurance questions

A documented location and cause is far more useful to an adjuster than a hole and a guess.

Common sources

Where they usually turn out to be

In this housing stock the same handful of culprits come up again and again.

Corroded galvanized supply developing pinholes inside walls, which is by far the most common in homes that were never repiped. Failing supply lines to toilets and under sinks, cheap to replace and responsible for a surprising share of ceiling damage. Shower valves leaking behind tile in original bathrooms. Water heater fittings. And out in the yard, a service line between the meter and the house that has taken on a pinhole and is quietly soaking the ground, often showing up as one suspiciously green patch of lawn.
