Hi melissaaimee/whale,
Having had health issues due to mould in a Strata Unit (which sounds remarkably similar to your complex – I hope you’re not in the same one!) it’s not the cold weather that is the problem but moisture. Mould growth is caused because the conditions are ripe for growth with the affected surroundings (common property) that provide the ideal conditions for mould growth.
The ‘wet’ weather may have helped exasperate the growth but the mould would have been there prior (lot of moulds/toxins are invisible), but it seems like your landlord and OC have established the presence of mould.
My advice would be to express your concerns with the landlord in a formal letter, seek a proposal to address the issue and state a reasonable timeframe for a response. Outline any further concerns you may have to ensure you are both on the same page. If you don’t hear back in a timely manner, apply to CTTT to have the issue formally dealt with.
With regards to the mould, the health issues can be excessive. If you have allergy like symptoms get checked by a specialist and tell them about the conditions you are living in. If a general ‘pin prick’ test is not conclusive (you may actually have an allergic disposition), there is a blood test available that is ‘a lot’ more conclusive. Either way an allergy specialist should be able to help you both out if you are suffering.
Best of luck and I hope it works out… if it doesn’t, you should move out!
