Mold & Mildew

WHY DO THEY OCCUR?

​Mold
It’s a kind of fungus that develops from airborne spores. It usually grows in damp, warm conditions without much airflow, which is why household bathrooms and loft spaces often suffer from mold. It is often simply caused by humid conditions and lack of ventilation, but sometimes mold on walls can be due to plumbing leaks, both inside and outside the property. Badly insulated heating pipes can also cause a build-up of moisture behind the walls.

Mildew
Name for the most common type of mold on walls, Characterized by spots that can then spread over larger areas if left untreated. Many decks, fences and concrete surfaces will have either green or black mildew.
