Here are a few suggestions:
- Make sure that gutters are clear and that downspouts carry water away from the house.
- Fix any signs where potential mould can grow.
- Make sure you look for standing water around refrigerators, toilets, water tanks, washers, anywhere water is used before you leave.
- Pay attention to plumbing.
- Keep your holiday-home clean before you’re departure – ensure to clean and disinfect along the windows.
- Eliminate clutter. Keep the air moving freely in every part of the house.
- Invest in a good dehumidifier. You will need a dehumidifier that can drain away continuously so that you don’t have to worry about emptying the container (which will fill up each day) and auto-restart so that if you have a power cut, the dehumidifier will restart in the mode that you set rather than go into standby mode waiting for you to press a button.
