There is nothing like the glow of a woodburning stove on a dreich January evening. But that glow depends on one thing above all: dry wood. In a British winter, rain and damp are relentless. Logs left exposed or stored in a sealed shed soak up moisture and burn poorly, wasting money and lining your flue with tar. A few practical habits and the right kind of shelter will keep your logs in perfect condition from autumn through to spring.

Why damp logs are a false economy

Freshly cut wood can contain more than half its weight in water. Seasoned logs should be below 20 per cent moisture, ideally around 15 to 18 per cent. When you burn damp wood, the fire’s first job is to boil off that water. Less heat reaches the room, and you get more smoke, blackened stove glass, and a rapid build-up of tar and soot in the chimney. That increases the risk of a chimney fire.

If you buy logs by volume, you are partly paying for water. Dry logs light more easily, burn hotter, and leave far less mess. A simple moisture meter, costing less than a bag of logs, will tell you exactly what you have.

The right kind of shelter: open sides, good roof

The ideal log store is a simple structure with a solid roof and open sides. Rain must be kept off, but air must be free to move through the stack. Solid walls, sealed doors, and plastic wraps trap damp air inside and encourage mould. A shed with no ventilation is one of the worst places for logs.

• Position: Place the store against a south or west-facing wall, in full sun and exposed to the prevailing wind. Avoid trees, which drip and shade.
• Base: Raise logs at least 100mm off the ground on a slatted timber pallet or metal grate. Damp rises from soil and concrete.
• Roof: Use a sloping roof with a generous overhang of at least 300mm to keep out driving rain.
• Sides: Leave them open. If driving rain is a problem, fit removable slatted screens that can be taken off in dry weather.

Stacking and seasoning for a proper burn

How you stack logs matters almost as much as where. Split larger rounds before stacking: smaller pieces dry far faster. Remove loose bark and shake off dirt. Stack loosely, with the cut ends facing outwards so air can flow through. A criss-cross pattern at the ends helps.

Hardwoods such as ash, oak, beech, and birch need at least a year to season; softwoods like pine and spruce take six to nine months. Kiln-dried logs are ready to burn straight away, but if you store them outside, protect them just as carefully. Test a split log with a moisture meter: push the pins into the freshly exposed inside, not the outer face. Under 20 per cent is good; under 15 per cent is excellent.

In summer, leave the stack uncovered or just loosely covered to let the wind through. In autumn and winter, cover the top only. Never wrap a tarpaulin around the sides — that simply creates a humid microclimate.

Bringing logs indoors without making them damp again

One of the most common mistakes is carrying a wheelbarrow load of cold logs straight into a warm living room. Condensation forms on the cold wood, making it damp again within hours. Bring in only a day or two’s worth at a time.

• Small batches: Use a log basket or canvas bag and fill it no more than you will burn in 24 to 48 hours.
• Acclimatise: Let logs sit in a cool porch or utility room for a day before bringing them to the stove.
• Keep away from heat: Do not stack logs against radiators, external walls, or the stove itself. A basket beside the hearth is fine, but keep a safe distance from the flue.
• Indoor rack: A small slatted rack near the door lets air circulate and catches loose bark and debris.

Using sheds, shelters, and outdoor rooms wisely

A garden shed can work as a log store if you adapt it. Fit vents at low and high level to create a chimney effect, keep the door slightly ajar on dry days, and lay a slatted floor. Without these changes, a shed becomes a damp box.

Dedicated log stores — often simple lean-to shelters with open fronts — are better. They can be integrated into a larger outdoor room or covered seating area, but be careful. Insulated garden rooms and glazed summerhouses are designed to keep warmth in, not to dry wood. Storing logs there will raise humidity and may cause mould on the logs and the structure. Instead, keep the log store separate or in an unheated, well-ventilated lean-to. If you have a covered outdoor kitchen or potting area, a small open-fronted bay for logs is a practical addition.

Maintenance and troubleshooting through the wet months

Check your store regularly. White furry patches or a musty smell mean damp is trapped. Re-stack with more gaps and remove any solid covers from the sides. Clear gutters and check the roof for leaks before the worst of the winter.

Rotate your stock: use the oldest logs first and never pile fresh logs on top of seasoned ones. If a batch does get soaked, it can be re-dried, but it will take weeks. In the meantime, keep a small supply of kiln-dried logs or kindling indoors for immediate use. With a little care, your logs will stay dry, your stove will burn hot and clean, and your winter evenings will be exactly as they should be.
