How to Reduce Mold Caused by May Damp
With the arrival of warmer but wetter weather in May, many homes face an increase in dampness, which can lead to mold growth. Mold not only affects your home’s appearance and smell, but it can also impact your health—especially for those with allergies or asthma. This guide is for tenants and homeowners looking to keep their properties dry, fresh, and mold-free during the damp spring months.

Improve ventilation
One of the most effective ways to combat mold is by improving airflow throughout your home. Open windows when the weather allows, especially in areas like kitchens, bathrooms, and bedrooms. Use extractor fans where available, and consider investing in a dehumidifier to reduce moisture levels indoors.

Identify and fix sources of moisture
Check for leaks in roofs, windows, and plumbing—these are common culprits during May rains. Condensation on windows or walls can also be a sign of poor insulation or high humidity. Make repairs promptly and wipe down condensation-prone surfaces regularly to prevent mold from taking hold.

Dry laundry properly
Drying clothes indoors can add a surprising amount of moisture to the air. If outdoor drying isn’t an option, try using a tumble dryer or drying clothes in a well-ventilated room with the window open. Avoid placing damp clothes on radiators, as this can lead to condensation and eventual mold on nearby walls.

Keep humidity under control
Use a hygrometer to monitor indoor humidity. The ideal range is between 40–60%. If levels are consistently higher, it’s time to take action with moisture absorbers, dehumidifiers, or professional help. Bathrooms and kitchens often benefit from additional ventilation or regular use of fans even after use.

Regularly clean and inspect mold-prone areas
Check behind furniture, around window frames, and in corners where air doesn’t circulate well. If you spot any mold, clean it immediately using appropriate mold-cleaning solutions and wear gloves and a mask to protect yourself during cleaning.

If you’re struggling with damp or mold in your rented property, reach out to your landlord or property manager. For homeowners, it may be worth consulting a damp specialist to assess more serious or recurring issues.
