Hi Slap Shot,
On what basis are you requesting the owners corporation to lodge an insurance claim? The Owners Corporations insurer are unlikely to get involved unless there has been any damage caused to common property. They will then only pay for the repair of damaged common property once they are certain that the cause has been rectified (evidenced by a tradesman’s invoice etc.).
The core of the issue you need to get to the bottom of is what is causing the excess moisture which may be caused by a raft of problems (not all of which will be the owners corporations responsibility to repair).
It is not uncommon for executive committees to want to inspect an issue prior to authorising the strata manager to engage a contractor in order to keep a check on expenditure incurred by the SM on their behalf (as can be witnessed by many concerned posts on this forum).
Now, if the EC members who made a visual inspection could not see a visible problem, I would recommend arranging for your own inspection of your unit. Once you have a professional opinion on whether there is: 1) a problem existing, and 2)what is the cause and solution to this problem; you will be in a very strong position to demand the owners corporation to rectify (if appropriate).
If the repairs and/or damage turn out to be claimable under the owners corporation’s insurance policy, then the strata manager should lodge a claim on behalf of the owners.
Please be aware that the most common cause of damp problems in apartments are the result of poor ventilation – especially in older buildings.
Good luck.
