Step one: Testing
Find the source
Before anything is installed, find out what’s feeding the damp. Testing shows humidity and moisture levels, so the work is aimed at the cause rather than guessed at.
Your goal
Improve mould and ventilation
Mould isn’t a cleaning problem – it’s a moisture problem. Find where the moisture comes from, get it out of the house, and the mould has far less to feed on.
This goal usually involves
Sealing a house keeps moisture in as well as heat. Plan the ventilation alongside the sealing, not after the mould turns up.
The pathway
Do it in this order.
You don’t have to tackle everything at once. But sticking to this sequence means each later upgrade can be smaller and cheaper – even if you space them out over years.
Step two: Ventilation
Get the moisture out
Damp air has to go somewhere. Sub floor fans dry out the space under the house, and heat recovery ventilation swaps stale indoor air for fresh without throwing the warmth away.
Step three: Insulation & draughts
Then seal and insulate
With ventilation in place, insulation and draught sealing keep the house warm without trapping the moisture. Warmer walls and ceilings also mean less condensation forming on them.
Not sure where to start?
Stop guessing, start saving: find your home’s energy score.
Don’t waste money on upgrades you don’t need. A professional home energy assessment shows where your house loses heat and power, so your budget goes where it makes the biggest difference.
