Here are common signs to look out for which will indicate if you have a mould issue or not:
Allergic Symptoms from Mould
If you are having a problem with allergies, then there's a good chance there could be mould growing somewhere in your home. Common allergic reactions to mould include sneezing, sore eyes and a runny nose or nasal congestion. Do you notice your allergic reactions are worse when you're at home but you feel better when you go out? If so then it's especially likely you could have mould. If you find that your allergies are worse in some other building, like your workplace, then there could be mould growing there instead.
Smelling a Mouldy Odour
When you have mould growing hidden away indoors, often a mouldy smell might be the only clue that it's there. Don't ignore mould odours if you can't see any mould. You should thoroughly inspect your indoor environment before any mould problems get worse.
Seeing Signs of Mould Growth
Visible mould growth might seem like an obvious sign of mould. However, many people don't notice small amounts of mould growth or they think it's just soot or dirt. Sometimes people simply ignore visible mould in their house. If you can see mould growth, even if it's only small, you should take action immediately. Small mould patches can spread and the fact that there is any mould shows that the conditions indoors are right for mould to grow.
If you don't take care of mould it will soon become a bigger problem. Visible mould growth could also be a sign that there is a much larger mould colony growing hidden away from view. Some mould growth looks white and thread-like. Other mould appears as clusters of small black spots. Mould can be black, grey-brown, grey-green or white in colour.
It is imperative that if you can answer yes to any of these signs or symptoms that you get the professionals to have a look as interfering with it on your own may worsen the situation.
