Five Quick Fixes to Keep Rental Properties Mould Free in Wet Weather

18th February 2026

You have probably seen the news that it has rained somewhere in the UK every day so far this year. So while it has been raining cats and dogs, now is a good time to focus on the easiest ways to keep your rental property damp free.

One of the most common issues agents report, particularly in coastal and high rainfall areas, is mould. Often this is linked to condensation and day to day living habits, which is why it is important to work with a managing agent that educates and informs tenants before submitting repeated maintenance requests and contractor invoices. Regular tenant updates and short newsletters with practical tips on ventilation and heating help residents protect their homes and in turn save landlords unnecessary hassle and cost.

Did you know we also send tenants a monthly newsletter with local discounts and useful tips for maintaining their home, alongside regular check ins from their property manager? Proactive communication like this reduces avoidable maintenance and keeps properties in better condition.

Aside from tenant behaviour, it is still essential to keep your property as sealed and weather resistant as possible. Here are five quick fixes that make a noticeable difference.

1. Check roofs, gutters and drainage
Persistent rain quickly finds weak points. Look for slipped tiles, damaged flashing and blocked gutters. Ensure downpipes discharge away from walls and that soil or paving has not built up above the damp proof course. Keeping rainwater moving away from the building prevents moisture entering the fabric.

2. Make sure ventilation actually works
Most mould starts with trapped moisture. Check that bathroom and kitchen extractor fans run effectively and vent outdoors. Confirm window trickle vents are open and not painted shut. Humidity controlled fans are a simple upgrade that manages moisture automatically.

3. Keep steady background heat
Cold, underheated rooms attract condensation. Annual boiler servicing and balanced radiators help maintain even warmth. Modern controllable heating makes it easier for tenants to keep a low consistent temperature, which greatly reduces mould risk.

4. Seal the small gaps that let water in
Wind driven rain can enter through surprisingly small openings. Seal gaps around window frames, doors, pipes and cables. Replace tired silicone around baths and showers and fix minor leaks promptly before damp spreads into surrounding materials.

5. Keep tenants informed and engaged
If mould requests are increasing, share simple reminders about ventilation, heating and reporting early signs of damp. Encouraging tenants to open vents, use extractors and flag issues quickly helps distinguish lifestyle condensation from genuine defects and speeds up resolution.

With so much rain this year, a combination of good maintenance and clear tenant guidance goes a long way. A well sealed, well ventilated property stays drier, healthier and far less prone to mould.
