You can demonstrate damp by taking readings with a damp meter – not expensive and obtainable from Bunnings.
Or you can just say to the strata manager, “how about I take the owners corp to NCAT to force them to fix this, and you to Fair Trading for incompetence, while I’m at it?”
Too many strata managers see their job as being to protect the committee by minimising spending at some individual owners’ expense, including their health. If the strata manager won’t budge, talk to a lawyer (click on the ad at the top of the page) or Flat Chat’s friends at StrataAnswers.
