Plastic sheds are a good option for those seeking a low-maintenance, short-term storage solution. However, they are not entirely maintenance-free. One of the main issues with plastic sheds is condensation, which can lead to mould and damage to the contents of the shed. This occurs when warm, moist air hits a colder surface, such as the roof or walls of the shed. While proper ventilation can help reduce condensation, it is important to note that plastic sheds are excellent insulators, trapping heat and moisture inside. To prevent condensation, it is crucial to minimise dampness in the foundations and ensure that the shed is anchored to a firm, level foundation with proper drainage.

What You'll Learn
Plastic sheds are prone to condensation
Plastic sheds are particularly susceptible to condensation when there is dampness in the foundations. The air inside the shed is always slightly warmer than the outside, so any moisture in the foundation will rise until it touches the cold roof panels. The moisture then condenses, drips down, and becomes part of a condensation cycle. This is difficult to stop, so it is important to minimise dampness at the outset.
To prevent condensation in your plastic shed, it is advisable to take similar measures to those used for a timber shed. For example, proper shed placement can make a difference. Position the shed away from areas prone to water accumulation and ensure it has a solid and level foundation to prevent water seepage and encourage drainage. A well-drained location is key.
Proper ventilation and airflow within the shed are also important to reduce the chances of condensation and moisture buildup. This can be achieved through vents or by simply opening the windows to let fresh air in. However, more ventilation can also make the shed colder and increase condensation, so it is important to keep the shed a few degrees warmer at night to prevent the air from getting down to the dew point.

Ventilation and airflow prevent condensation
Plastic sheds are prone to condensation, which can cause mould and damp. However, this can be prevented through proper ventilation and airflow.
Condensation occurs when warm, moist air hits a cold surface. As plastic is a great insulator, it keeps the heat inside a shed well. But because plastic is not breathable, it also keeps water inside. The air inside a shed is always slightly warmer than outside, so any moisture in the foundation or seepage from outside will rise until it hits the cold roof and wall panels. It then condenses into water droplets, which drip down and become part of a condensation cycle.
To prevent condensation, ensure your shed has adequate ventilation and airflow. This can be achieved through vents or by simply opening the windows to let fresh air circulate. Weatherstripping can be used on windows, doors, and gaps to improve airflow. It is also important to routinely inspect your shed to identify and fix any sources of dampness. For example, thick vegetation surrounding your shed can block airflow, creating a humid microclimate inside. A weak or poorly constructed plastic shed base can also worsen moisture problems.
When building a shed, it is important to let the foundation "cure" for at least seven days after casting the concrete, and longer if the atmosphere is damp. This will prevent the water drying up from the concrete from creating a condensation cycle. After bolting the shed to the concrete or slabs, apply mastic or silicone sealant to the inside of the shed base rails to preserve drainage and prevent water seepage.

Damp foundations cause condensation
Plastic sheds are prone to condensation and must be ventilated regularly to protect their contents from mould and damp. While rot and mould are not an issue with plastic sheds, condensation can cause mould to grow, which can damage equipment and furnishings.
Damp foundations are a common cause of condensation. Water can seep into a shed through its foundation floor and walls. This is known as rising damp and is often present in older buildings, which typically lack a waterproof barrier between the ground and basement-level floors and walls. Building materials used in old basement walls, such as concrete and cement, are porous, meaning damp vapours travel through them easily.
To prevent rising damp, it is important to have a solid and level foundation for structural support and to prevent water seepage. A well-built foundation should have a proper footing design and a proper connection between the foundation wall and the structure above. For example, anchor bolts or straps at the sill plate and floor joists nailed to the sill plate.
In addition to a well-built foundation, proper shed placement can also help to prevent damp. Position the shed away from areas prone to water accumulation and ensure it is in a well-drained location. You can also seal the concrete to stop water from penetrating through.
If you are experiencing condensation in your plastic shed, there are a few things you can do to try and reduce it. Firstly, ensure the shed is well-ventilated by opening windows or using vents. You can also try to keep the shed a few degrees warmer at night to prevent the air from getting down to the dew point. Using insulation or a small heater can help with this.

Condensation prevention methods
Proper Shed Placement
Position your shed in a well-drained location, away from areas prone to water accumulation. Ensure that it is not situated near water sources like sprinklers or downspouts, as this can increase the chances of moisture finding its way into the shed. Avoid placing it too close to thick vegetation, as this can block airflow and create a humid microclimate inside.
Solid and Level Foundation
A solid and level foundation is crucial for structural support and to prevent water seepage. Consider using a steel foundation kit, applying a waterproof membrane, and sealing seams with waterproof tape. Alternatively, you can seal and waterproof a concrete foundation to prevent moisture penetration.
Ventilation and Airflow
Proper ventilation and airflow are key to reducing condensation. Install air vents near the roofline to allow warm, moist air to escape. Exhaust fans can also be placed on the floor or ceiling to remove humidity from the shed. Opening doors and windows can help improve airflow, especially in smaller sheds.
Insulation
Insulation helps raise the surface temperature, preventing condensation and reducing heat loss. It also acts as a vapour barrier, preventing moisture from entering the shed. Insulation products with a reflective foil surface and a closed-cell foam structure are ideal for this purpose.
Dehumidifier
Using a dehumidifier is an effective way to remove moisture from the air, especially if you are storing valuable items that are sensitive to moisture. While this method may be more costly, it is worth considering if you have items that could be damaged by excess humidity.
Anti-Condensation Products
There are various anti-condensation products available, such as paints and spray foams, designed to protect the underside of your shed roof. Anti-condensation roof sheets can also be installed, but ensure that your ventilation is sufficient to prevent the sheets from holding too much water.

Condensation and mould
Plastic sheds are prone to condensation, which can lead to mould and damp. This occurs when warm, moist air hits a colder surface, such as a roof or wall panel. While plastic sheds are excellent insulators, they are not breathable, so they can trap water vapour inside.
To prevent condensation and mould, it is important to minimise dampness in the foundations and ensure proper ventilation and airflow. When building a plastic shed, it is essential to follow the manufacturer's instructions correctly, ensuring proper overlapping of roof and wall panels. The foundations should be solid and level, with a damp-proof membrane, to prevent water seepage and encourage drainage. The ground must be well-drained and level, and the shed should be positioned away from areas prone to water accumulation.
Proper ventilation is key to reducing condensation and moisture buildup. This can be achieved through vents, windows, or by simply opening doors to let fresh air circulate. Routine inspections are necessary to identify and fix any sources of dampness, such as leaks or cracks. In very cold climates, keeping the shed a few degrees warmer at night can help prevent the air inside from reaching the dew point and condensing.
While mould and rot are not typically issues with plastic sheds, condensation can still cause damage to the contents of the shed. Therefore, it is important to take preventative measures to minimise condensation and ensure proper airflow and ventilation.
