A damp shed is usually caused by condensation or from water entering the shed, normally through a leak. It can be disastrous, because damp can cause extensive damage and rot to your shed, as well as ruining expensive tools or equipment stored inside. With this in mind, here’s how to stop a shed getting damp.
General maintenance and carrying out repairs to your shed is perhaps one of the key points when looking at how to stop a shed getting damp.
Every year, apply a wood treatment to the exterior walls to prevent moisture getting in and making your shed damp and mouldy.
Inspect the windows and doors on your shed; check for damage or decay and make repairs as necessary. Any gaps where rainwater can get in are likely to cause damp, so close them up or apply a sealant around windows to prevent leaks. Make sure your shed guttering is not blocked or damaged, which can cause leaks through your shed roof.
Check your shed roof, including the felt for tears or rips and repair where necessary. When it’s time to replace the felt, you may want to consider applying a damp proof membrane to the shed roof to help prevent moisture from forming inside.

Insulating your shed will raise the surface temperature, which will help to prevent condensation and therefore damp. Insulating your shed will also make it more efficient in preventing heat loss. Solid foam insulation is available in different thicknesses and provides the most effective form of insulation for sheds.
If you’re wondering how to stop a shed getting damp, then one of the best things you can do is ventilate it. Ensuring you have air circulating around your shed prevents a build-up of moisture. Install windows and vents which can help combat stuffy air or, if you’re short on space with no room for windows, opt for fans or a whirlybird vent.
Open the windows and door every few days on milder days throughout the year to help keep moisture levels down and prevent the build-up of damp in your shed. Ventilation throughout the year is essential and can help prepare your shed for winter.
Heating your shed can help control the damp levels. If your shed is connected to electricity, then there are several options for heating including electric radiators or electric convention heaters. If you’re not connected to electricity, then a wood burner can work well.
If you live in a coastal area, or if somewhere that is prone to a high level of rainfall, you may want to consider installing a dehumidifier which can help prevent damp.
Thinking about how to stop a shed getting damp is important, because it means protecting and enhancing the longevity of your shed. Preventing damp within a shed also means protecting your tools, equipment or whatever you have stored inside too.
