FAQs

We answer your most pressing questions!

Looking to eradicate damp & mildew in your property?

Properly ventilating your property requires fresh air to be supplied and stale air to be removed, along with the moisture in the room. Mould and mildew build up over time when moisture build-up isn't addressed. We have a range of intermittent, continuous and PIV fans units that help to remove stale and damp air to minimise the chances of having a harmful internal environment.
