7 Ways to Prevent Condensation In Your Shed

Condensation occurs when warm, moist air comes into contact with cooler surfaces. This can lead to rusting, mould, and mildew, damaging the structure of your shed and any items stored within. 

Today, Atlas Sheds will discuss effective strategies for keeping your shed dry, comfortable, and condensation-free. This will increase the durability and longevity of your garden structure.

1. Increase Ventilation

There are many ways to increase the ventilation in your shed to ensure an ongoing supply of fresh air. Two of the most common options include:

1. Install air vents: Air vents are the perfect way to improve air circulation in your shed. Place them near the roofline to allow warm air to escape. 
2. Exhaust fans: Exhaust fans remove moist air from inside the shed. Place these on the floor or ceiling to prevent humidity from settling onto surfaces. 

2. Use Insulation

Insulation helps to keep your shed warm throughout the winter whilst preventing the warm, moist air from condensing on cold surfaces. 

Materials such as tone-based mineral fibre insulation, PIR boards, and rigid foam boards are excellent options for shed insulation and are very thermally efficient. 

Place insulation on the walls, floors, and ceiling to seal all points where moisture can seep in. 

3. Employ a Dehumidifier

This proactive approach is beneficial for climates with high humidity levels or during summer when the air tends to be damper.

Dehumidifiers draw moist air in and release dry air back into the environment. Choose the perfect size for your shed for effective ventilation. Avoid placing it behind furniture where airflow is restricted. 

4. Install a Concrete Vapor Barrier

Concrete vapour barriers prevent moisture in the ground from seeping into the structure of your shed.

This is a polyethene plastic sheet that is laid over the ground before the concrete slab is based. The ground should be levelled and prepared before the barrier is placed. 

Ensure it covers the entire area to prevent mould and mildew growth. 

5. Caulking and Sealing

Caulking and sealing is a method used to cover up small gaps, cracks, and holes in your shed. 

Inspect any windows, doors, and the base of your shed for any damage. It’s also important to examine the corners of your roof where the joints meet for cracks in the ceiling. 

Choose a silicone-based caulk and use a caulking gun to apply the substance to any cracks and gaps in your shed.

For larger gaps, use expanding foam insulation or weatherstripping to protect your shed from moisture ingress. 

6. Proper Storage and Organisation

A cluttered shed leads to poor air circulation. This causes a buildup of moisture, leading to condensation on the surfaces of your shed.

To prevent this, organise your shed, throwing out old and rusted objects. Add vertical shelving and use airtight plastic storage boxes to contain your items. This reduces the risk of moisture damage. 

For large equipment or furniture, elevate them off the ground using pallets or stands to improve air circulation. Silica gel packets can be added to storage containers to absorb moisture. 

7. Install a Window Fan or Air Conditioner

A window fan can be used to pull fresh, dry air into the shed and expel any stagnant, humid air. 

You can adjust the fan's settings during different seasons to prepare your shed for changing weather. This is an energy-efficient and cost-effective solution to reducing condensation. 

Air conditioners are best used in environments that are constantly hot and humid. They remove moisture from inside your shed and lower temperature levels, making your shed more comfortable.
