Why am I getting Mould in my shed?

If the outside temperature drops, any moisture inside the shed will cause condensation on the inside of the shed panels, roof, floor and possibly other items stored in the shed. This condensation will cause mould and mildew to form very quickly.

Moisture and Mould Issues In My Garden Shed

Garden sheds can suffer from moisture and damp issues at certain times of the year. Wooden sheds are even more prone to these problems, as timber is a perishable material. Winter and Spring are the main times, when there may a high level of moisture in the air. This is caused by wet weather and damp conditions.

Effects of moisture are…

Premature rot

Mould on interior panels and roof

Warping and sagging of timber

Preventing Damp Issues

There are a few things that you can do to prevent and minimise the damage which can be caused by moisture. A major cause of rot in garden sheds is rising damp, this is caused by ground water being absorbed through the floor bearers and into the floor. To prevent this from happening it is best sorted during the initial planning stages of siting and building the shed. You will need a barrier between the ground and the floor of the shed, to stop the moisture entering. How you do this will depend on what type of base you are using on which to position the shed... Bases made using gravel allow any rain water to flow freely through it and prevent water from pooling. This reduces the chances of water being soaked up by the floor bearers. Timber bases can be used to raise the shed completely off the ground, so that it is almost impossible for water to penetrate the floor bearers. Concrete and paving slab bases need to be a level as possible to allow water to run off and prevent it from pooling. A shed that sits in puddled water will inevitably absorb water. Not only can sheds suffer from ground moisture, but also from moisture in the air. This issue is particularly prevalent in Winter. Moisture, caused by damp, wet conditions can get trapped inside sheds, especially if they are not used often. If the outside temperature drops, any moisture inside the shed will cause condensation on the inside of the shed panels, roof, floor and possibly other items stored in the shed. This condensation will cause mould and mildew to form very quickly. To combat this issue, it is advised to allow the shed to vent as often as possible throughout the winter. This will enable fresh air to circulate around the building and stop moisture from building up. To do this, you can open the windows if you have them or leave the door open from time to time. It is also a good idea to not store wet or damp items in the shed, like garden tools or bikes etc… Try to dry them off before returning them to the shed. If you do get mould forming, it is advisable to remove it as quickly as possible with an anti-mould cleaner, before it penetrates and permanently damage the timber.

Is there a GFCI extension cord?

GFCI devices are available in wall mounted receptacles, circuit breakers, and portable devices like extension cords. Using GFCI extension cords offers protection against electric shocks and potentially lethal electrocutions.

rewci.com - Why Use GFCI Extension Cords? - R.E. Williams Contractor Inc.

As a matter of safety and best practices application, both homeowners and contractors should use GFCI protection when using extension cords in wet or even damp locations. GFCI, which stands for "ground fault circuit interrupter", is a safety device that prevents electrocutions, electric shocks, and burns from occurring year-in and year-out around the home, workplace, or construction site. Most importantly, GFCI devices are designed to protect people from severe, or even worse, fatal electric shocks. GFCI products detect ground faults, which can stop electrical fires before occurring or retard their progression. When electric current is leaking, it's said to have a ground fault. GFCI devices are available in wall mounted receptacles, circuit breakers, and portable devices like extension cords. Using GFCI extension cords offers protection against electric shocks and potentially lethal electrocutions. These devices monitor flowing electricity in a circuit. If there is a discrepancy between the amount of amperage current flowing and amperage current returning, the GFCI quickly turns off power to that circuit to protect the user from potential electrocution. GFCI extension cords can be used inside or outside. Homeowners should use the outdoor-rated, water-resistant GFCI heavy duty extension cord outside for lawn and garden tools and equipment, appliances, or holiday lighting. They offer ideal protection against electric shock from damaged cords or water exposure. Made out of 12-gauge cord, a GFCI heavy duty extension cord is strong and durable. Available in 25 ft, 50 ft, and 100 ft, coupled with three prong conductor cord, they can meet every need.
