We rent a 2-bedroom basement apartment in North Vancouver, BC. It does rain a lot and a wet puddle forms in my son’s bedroom. This house is 60 years plus, but we just found mould growing under my sons bed, black and brown mushroom looking. We have only lived here for 10 months. What are the health issues we face? I am 56 years and I have heart disease. My son is 24 years and has breathing problems. Our small dog, a 7 year old Bichon Frise sleeps a lot.
