Mould removal and treatment

Mould keeps coming back unless the moisture feeding it is fixed. Mould specialists treat the growth and help track down where the damp is coming from.

A common sign

“We clean the mould off the bedroom wall and it’s back a month later.”
That’s because the moisture is still there. Cleaning removes what you can see. Finding the source is what keeps it away.

About mould removal and treatment

Treat the mould, and find what’s feeding it.

Mould grows where moisture sits: on cold walls, in poorly ventilated rooms, around leaks and in damp corners. Treatment removes the growth safely, so spores aren’t spread through the house.

The more important part is finding why it’s there. It might be condensation, a leak, rising damp or poor ventilation. A good specialist will tell you what’s causing it and what needs to change.

Ask this

Ask what they think is causing the mould and how they’ll check. Treatment without fixing the cause usually means the mould returns.
