Are you looking to turn your garden shed into a stylish summer house or just sick of walking into a sweaty shed in the summer to get something?
You're not the only one.
There's nothing worse than a damp shed, and in the UK we can almost all say we have become witness to these issues. From rainy autumns, a cold winter, then warm summers-- there's no winning with British weather.
Lucky for you I have actually spent some time researching this topic, looking at the best way to get rid of pesky condensation in your shed so you can enjoy your summers or just access your tools with ease.
Now let me tell you something:
I have spent hours building this step by step guide, so we can get to the bottom of this annoying cause and ways to prevent and help reduce it in the future.
But enough of me chatting, let's get into it!
This is the first thing we need to look at is the cause. Metal garden sheds are most prone to condensation because moisture gets trapped inside the shed.
This is quite a task to prevent this as the inevitable temperature change throughout the year, on warmer days the water vapour in the shed will begin the evaporate to the roof and then when it cools down or reaches a cooler area (like the roof) then it will begin to condensate and drop back to the floor.
You may even notice water droplets on the roof as you walk into your shed.
This then turns into a vicious cycle and as this continues, more damage to your shed occurs-- not to mention the harmful bacteria and mould build up as a result of this process.
But there's no need to panic, I'm here to help.
Prevention is always better than a cure, which is why we're going to look at the assembly of the shed to prevent the cause before it's too late.
Fixtures and fittings: The number one issue may be down to the construction of the shed if your shed has tiny gaps in it, it may bring in the damp from the outside-- giving it a space for bacteria and mould breed.
The best way to help with this problem is to secure the panels and roof in place to be as tightened as possible to reduce any gaps.
Securing these panels will level out and reduce moisture in the atmosphere from getting inside of the shed.
You should also focus on having good insulation on the walls, roof and panels, especially around the windows and door to reduce the drastic temperature change.
The base of the shed: This is also another key cause of this problem-- fitting a secure base is crucial to reduce moisture seeping into the shed.
Well, the first rule of thumb to make your shed damp proof and protect it from moisture buildup is to keep your shed as dry as possible.
Keep your shed on a raised base floor, instead of on the ground. For example, use a concrete slab foundation to make sure that it has an effective moisture barrier underneath to limit water being transferred inside.
Make sure you allow a week or two for the concrete to fully dry all the way through before placing your garden shed on top, to reduce moisture even more.
Cutting off the source related to condensation by reducing water from entering the shed from the ground floor, will massively help with the condensation issue. Once the source of water is removed, so will the condensation as the shed will be dry.
Improve ventilation as a whole will allow the air to circulate which prevents air moisture and condensation.
You can do this by making small holes in each side of the shed to balance the air and temperature inside of the garden shed. This allows the moisture and condensation to escape, instead of building up inside.
But wait let me tell you something!
Keeping the garden shed well ventilated will allow for a breeze, good air circulation and less condensation.
With stopping the source of the problem and balancing out the ventilation as a whole, condensation will be massively reduced-- issues solved.
You can also prevent any damp from getting in by installing a damp proof membrane under the base, this prevents moisture from trickling up into the base-- causing all the problems.
This is something you should consider before building your shed as it may be more difficult after it is fully installed. Pairing this with a raised floor will massively reduce condensation in metal sheds.
Once everything is set up and ready to go you should check that the shed is well attached to the base with a waterproof sealant on the inside (don't do this on the outside). This allows for the moisture to drain outside instead of condensing inside.
But here's the kicker:
It also allows for a good amount of airflow between the floor around the base to help with the drainage of moisture further.
If your metal shed is also installed on a concrete slab without a damp proof membrane there are ways you can still reduce and limit the air moisture.
Installing and using a shed dehumidifier, window fan or install a few vents will let in the fresh air which will ensure to balance out the airflow. This will reduce the humidity of the shed and help circulate air and stop condensation.
If you have a hot shower, condensation builds up in the bathroom but once you open window it begins to clear, this is the same concept.
This is usually because the timber is much thicker (12mm usually), this then acts as insulation so it doesn't become too cold or too warm as the weather changes.
Metal is a strong conductor of heat and therefore is more prone to the problem of condensation, plus metal sheds are usually a lot thinner so they get colder in the winter and scorching hot in the summer.
Even though 12mm of timber isn't enough to keep a building warm it does help prevent condensation as drastic changes in weather conditions occur and prevent damage over time.
Timber garden sheds are also much more ventilated which helps circulate the air inside the shed, preventing condensation build-up.
The best way to solve the problem of condensation is to stop the source of water by adapting the base, make it more ventilated and well insulated.
This will allow you to store your belongings without having to worry about harmful moisture, bacteria, mould buildup.
This guide provides you with the best tips as prevention is always better than a cure-- hope this helps!
