If you have mould in your home, you know how hard it is to get rid of—and how much damage it can do.

Mould grows on surfaces like wood and wallpaper, but it can also grow inside the walls of your home. If you don’t deal with it quickly, mould can spread throughout the entire house.

Mould also produces toxic chemicals that can cause permanent damage to your health. If you suffer from a serious lung disease like asthma or COPD, mould can be life-threatening!
