Six Items You Must Never Store in Your Garden Shed, Experts Warn
Garden sheds are often seen as the perfect solution for extra storage space, but piling up spare items there can lead to serious hazards. According to specialists, storing certain items in outdoor structures can increase fire risks, attract unwanted pests, and cause damage that may go unnoticed until it's too late.
Paints, Solvents, and Thinners
Christopher Murphy MBE, founder of garden building specialists Dunster House, explains that keeping paints, solvents, and thinners in a shed is a common mistake. These items are highly sensitive to temperature changes. In cold weather, they can freeze and separate, while heat can make them unstable or unusable.
Better alternative: Store paint according to manufacturer instructions in a cool, dry, indoor spot like a closet or utility room, with a consistent temperature between 15-25°C, avoiding extreme heat, direct sunlight, and freezing conditions.
Fertiliser, Weed Killers, and Garden Chemicals
While it might seem logical to keep garden staples in a shed, chemicals like fertilisers and weedkillers risk clumping, leaking, or deteriorating in damp conditions. Extreme temperatures can diminish their potency and render them unsafe.
Better alternative: Keep these products in their original containers, sealed and stored in a cool, dry, well-ventilated area away from living spaces and food items. Raise bags off the floor using pallets or bricks, and seal open bags in lidded containers to keep moisture and pests out.
Electronics and Batteries
Temperature swings and dampness can wreak havoc on delicate components, causing corrosion and shortening their lifespan. Additionally, rodents seeking warmth in outbuildings may chew through cables and chargers, causing costly damage.
Better alternative: Keep electronics and batteries inside the house in a moisture-free, preferably airtight location.
Flammable Waste, Petrol, Fuel, and Oily Rags
Petrol, propane canisters, paints, and some solvents are highly flammable, and even a small spark can pose a serious fire risk in wooden sheds. Oily rags and cloths can self-heat over time and ignite without warning, especially in enclosed spaces during warmer weather.
Better alternative: Store these items in a container or structure designed specifically for flammable materials, such as a ventilated metal unit positioned well away from the house or boundary.
Food, Pet Food, or Animal Food
Anything edible that's prone to spoiling, attracting unwanted visitors, or deteriorating in fluctuating temperatures and humidity has no place in your shed. Sheds are not built to maintain the steady, cool conditions necessary for safe food storage.
Better alternative: Sheds are far better suited to non-perishable items only, and even then, food storage should be kept to a minimum wherever possible.
Paper and Photos
Moisture in the air, swinging temperatures, and inadequate airflow can cause paperwork and photographs to buckle, discolour, or develop mould. Vermin like mice and rats can also wreak havoc on paper, packaging, and stored possessions.
Better alternative: Crucial paperwork, cherished photographs, and treasured keepsakes should always be kept inside the home in a moisture-free, temperature-controlled setting.
