Find It Before You Fix It

A stain appears on a ceiling, somebody looks at the wall above it, finds a crack and seals it. The water was entering two floors higher at a window perimeter and tracking down inside the wall. The repair was competent, the building still leaks, and the owner has now paid for a repair that could never have worked.

The pressure to skip investigation is real and it is usually financial. A board has a leak, a budget, and owners asking when it will stop. Investigation costs money and produces a report rather than a repair, so it reads as delay. The result is a building that has been repaired three times at the place where water appeared, which is almost never the place where water entered.

Water travels. It enters at a failed joint or a penetration, runs along a slab edge or inside a wall cavity, and shows up somewhere else entirely — often a floor down and several units over. Repairing the stain treats the symptom and guarantees a fourth call. The investigation is not an overhead on the repair; on a building that has already been patched more than once, it is the only thing that changes the outcome.

1. 01Investigate before scoping, always.
2. 02Test systematically rather than spraying the whole wall.
3. 03Open up where the evidence points, with the owner's agreement.
4. 04Report the finding in writing before pricing.

Note the conditions when the leak appears — wind direction, rainfall duration, whether it happens in every storm. That pattern narrows the search enormously and it is information the building's occupants already have.
