Verified, Not Assumed

A repair is completed and everybody waits for rain. If it leaks again the owner has lost months, the interior damage has continued, and nobody can tell whether the repair failed or a second path exists. Testing on completion answers that immediately.

Testing after the work is the easiest thing on a program to drop, because by then the building looks finished, the scaffolding costs money every week it stands, and everyone wants to be done. It is also the only step that distinguishes a repair that worked from a repair that looks like it worked. Envelope work is largely invisible once complete, which is precisely why it needs verification rather than inspection.

The practical consequence of skipping it is that the next rain is the test, the scaffolding is gone, and any failure now costs mobilization again. Testing while access is still standing is dramatically cheaper than testing after it comes down. That is the whole argument, and it is an argument about money rather than about diligence.

1. 01Test every repair before declaring it complete.
2. 02Document the test and give the record to the owner.
3. 03Investigate further if the test is not clean.
4. 04Not rely on the next storm as verification.

Ask any envelope contractor whether they water test after repair. Most do not, and the honest reason is that a test can show the repair did not work — which is exactly why it is worth doing.
