How to Store Firewood: Safe, Dry, and Ready to Burn

Storing firewood properly makes a noticeable difference to how your appliance performs. Dry logs burn hotter and cleaner. They keep your chimney safer. They save you money. They also make those winter evenings feel calmer because you’re not fighting with a fire that refuses to light.

As a chimney sweeping company working across homes and businesses since 2010, we’ve seen every firewood setup possible — the good, the great, and the risky. Safe firewood storage is simple once you understand the basics. Here, we’ll take you through everything you need to know about how to store firewood.

What’s the best way to store firewood?

Wood burns best when it’s properly seasoned and kept dry. The best way to store firewood is:

• Off the ground: Logs absorb moisture from soil or concrete. A raised base prevents damp climbing into the stack.
• Under cover but with airflow: A roof protects the wood from rain, and good ventilation ensures it continues to dry.
• Stacked neatly in rows: Neat rows improve airflow, help moisture escape, and stop mould forming.

In the UK climate, outdoor storage works well when the logs are protected by a roof and open sides. Wood needs both shelter and airflow. Fully enclosed boxes trap moisture. Leaving logs uncovered invites rain. A good log store sits between those extremes — practical, breathable, and easy to access.

If you’re storing kiln-dried wood, the principles are the same. Kiln-dried logs are low-moisture on delivery, but they’ll still pull moisture from the environment if stored badly.

Is it safe to store firewood indoors?

Indoor firewood storage works best when you only bring in what you need for a few days. A small stack by the stove is practical and convenient, as long as you refresh it regularly. Larger indoor piles tend to trap moisture, attract pests, create smells, and introduce avoidable fire safety risks.

Keeping the bulk of your firewood outside, where it can benefit from proper ventilation, helps your appliance burn more cleanly and keeps your home’s air quality healthier. When you do bring logs indoors, place them in an open basket with plenty of space around it, and avoid stacking them directly against a wall where airflow is limited.

Is it okay to store firewood in a garage?

A garage is fine for firewood if the garage is well ventilated. Many garages stay damp, which slows the drying process and encourages mould.

For garage storage to work well:

• Keep logs raised off the floor on pallets or shelves
• Allow air to circulate around the stack
• Avoid placing wood against cold external walls
• Keep the garage door open occasionally to refresh the air

Garages attached to homes tend to be warmer and drier, but still need airflow. Detached garages can be much colder and more humid. If the space feels damp, treat it like an outdoor location and prioritise ventilation.

Where not to store firewood

Some places cause more problems than they solve. Avoid storing firewood:

• Against your house: Timber attracts insects. Storing logs against exterior walls encourages pests to explore the property. It also traps moisture, increasing the risk of rot and mould.
• Directly on soil or grass: The bottom layer absorbs ground moisture, ruining the whole stack.
• In fully sealed containers: Closed boxes without ventilation turn into damp, mouldy chambers.
• Under tarps that touch the wood: A tarp pressed against the logs traps moisture and stops them drying.
• Inside lofts or basements: These spaces tend to be humid, poorly ventilated, or difficult to inspect for pests.

Think of firewood as a natural material that needs airflow and a dry base. Anywhere that restricts those two things is best avoided.

Does firewood need to breathe?

Yes. Firewood needs airflow to dry properly. Moisture escapes from the cut faces and moves into the surrounding air, and without good circulation the wood stays wet.

If your logs aren’t breathing enough, you’ll often notice mould forming, mushy or softened ends, mushrooms appearing between the pieces, a strong damp smell, or a stack that seems to take far too long to season. Ventilation matters just as much as keeping the top covered. Wood that can’t breathe simply won’t burn well.

Should you cover firewood?

Covering firewood helps protect it from rain and winter weather, but the way you cover it matters. Firewood needs airflow to stay dry, and the big mistake people make is wrapping the entire stack in a tarp. That traps moisture, slows seasoning, and encourages mould.

A good cover keeps rain and snow off the top while allowing the sides to breathe. The best method is:

• Cover only the top of the stack
• Keep the sides open for ventilation
• Secure the cover so it doesn’t flap against the logs
• Use a raised board or battens so the cover never touches the wood directly

In winter, a roof or partial cover becomes even more important. Cold winds, frost, and repeated freeze–thaw cycles all drive moisture back into the logs. A simple sheltered setup works well:

• A roof or top cover
• Open sides
• A raised base so the pile stays dry in wet weather
• A wind-protected location if possible

Logs don’t need wrapping. They need shelter and airflow. Keep the top protected and the sides open, and your firewood will stay dry, season well, and light easily all winter long.

Is it better to store wood vertically or horizontally?

Horizontal stacking is the safest and most stable method. The airflow is better, and the wood isn’t bearing its full weight on a single end.

Vertical stacking — standing logs upright — works only for short-term storage or decorative indoor displays. Outdoors, vertical stacks topple easily and trap moisture.

For long-term, safe storage, horizontal rows are the strongest approach.

Should wood be stored bark up or down?

This is a classic debate, and there’s a simple answer.

Bark facing up outdoors helps repel rain. It acts like a natural umbrella.

Bark facing down indoors or in a covered store can help moisture escape from the cut face more easily.

If your logs are under a roof and protected from rainfall, the bark direction makes little difference. If they’re partially exposed to the weather, bark-up provides better water shedding.

How long can you store firewood for?

Firewood lasts for years when stored well. Most hardwoods (oak, ash, beech) become optimal at around 18–24 months of seasoning. Softwoods dry faster, often within 6–12 months.

Once seasoned, wood doesn’t “expire”, but it does continue to age. Over several years, it can become more brittle, lighter, and faster burning. That doesn’t make it unsafe — it’s simply less dense.

The real issue is moisture. If your logs stay dry, you can store them for 3–4 years or more without a problem. If they get repeatedly damp, the lifespan shortens due to mould, rot, or insects.

How to store logs without a log store

Not everyone has space for a purpose-built log store. The good news is that you can still store firewood safely using simple materials.

• Use pallets: Stack two or three pallets on the ground to create a raised base. Add more pallets at the back to act as a wall. This instantly improves airflow and stability.
• Lean-to structure: A basic lean-to against a shed or fence works well, as long as the logs don’t directly touch the wall. Leave 5–10cm of space for ventilation.
• Metal shelving units: Outdoor-rated shelving creates a sturdy, elevated, breathable structure.
• Builder’s bags: Use only for seasoned wood. Keep the bag open at the top to allow moisture to escape. Don’t cinch it closed.
• Old crates or fruit bins: Strong, slatted wooden crates create perfect mini-stores with built-in ventilation.

You don’t need a fancy log store. You just need airflow, a dry top, and a raised base.

As chimney sweeps, inspectors, and HVAC specialists, we understand exactly what keeps a system running cleanly — and what puts a property at risk.

• Keep your firewood at least 5 metres from your home to reduce pest risk
• Store only a small indoor supply
• Sweep your chimney annually (or more often for heavy use)
• Use Ready to Burn certified suppliers where possible
• Avoid burning treated, painted, or construction timber

Dry wood burns cleaner and keeps your chimney safer. The safer your chimney, the safer your home.
