My apartment was built in 2005 and I moved in very soon after it was completed. Almost immediately, I started noticing a funky damp smell. I told the builders when they came in to fix up the apartment defects but they assured me it was just the dishwasher (which I have never used).
Since that time, the skirting near the sink has been deteriorating. The paint bubbled and the wood is expanding and then mould started to grow. Things came to a head last year when an overseas friend came to stay. I found him the next morning sleeping on the balcony. Apparently he had suffered an adverse reaction to the mould and spent the rest of his time in Melbourne staying with other people. I felt terrible.
Anyhow, I told our onsite manager earlier this year. He inspected the damage and suggested that there was definitely a leak under the kitchen bench somewhere. He said he would contact the builder.
Six months passed and then, last night, the builder gives me a call. He will check it out this morning. I hope he can identify and fix the problem.
