* A common problem that is not addressed indoors is fixing your water leakages. Very often, we ignore water leakages into the home, which then allow the growth of fungus, mould, and mildew, which causes or worsens conditions such as asthma, wheezing, and sinus. Taking precautions such as fixing of leakages, maintenance repairs to prevent loss of heat/ cold indoors, will ensure better air quality inside.
