If you burn wood at home, you already know that a pile of logs sitting on bare soil is a recipe for rot, bugs and smoky fires. The good news: you don’t need a fancy shed or an expensive metal rack. With two concrete blocks and six sturdy boards, you can build a simple V-shaped firewood rack in under an hour that keeps your wood off the damp ground and lets air flow around every log.
Why raise firewood off the ground?
Wood that touches soil wicks up moisture, stays wet longer and becomes a home for insects, fungi and mice. Raising your stack even a few inches makes a big difference:
- Better drying: air moves underneath the stack as well as around it.
- Less rot: the bottom row no longer sits in puddles or wet grass.
- Cleaner wood: fewer bugs, less mud carried into the house.
- Easier fires: dry, seasoned wood lights faster and produces less smoke and creosote.
Materials you’ll need
- 2 standard concrete blocks (hollow cinder blocks with two openings)
- 6 sturdy boards, such as 2x4s (pressure-treated or naturally rot-resistant lumber lasts longest)
- A saw, tape measure and level
- Optional: a tarp, metal roofing panel or a few boards for a top cover
How to build the V-shaped rack
- Pick a firm, level spot. Choose well-drained ground away from your house walls. Compact the soil or lay a few pavers so the blocks can’t sink or tilt.
- Place the blocks. Set the two concrete blocks parallel to each other, openings facing up. The distance between them sets the length of your rack (6 to 8 feet is a practical size).
- Add the base rails. Lay two boards horizontally between the blocks so the logs have a raised bed to sit on. They keep the bottom row off the soil.
- Insert the uprights. Slide two boards into the openings of each block, angling them outward to form a “V” at each end. Push them down firmly so they are well seated.
- Check for stability. Make sure the uprights don’t wobble. If they do, wedge small wood shims into the block openings.
- Stack your logs. Load the wood across the base rails, keeping the stack tight and even. Don’t stack higher than the uprights.
Tips for a safe, long-lasting rack
- Avoid overloading. A V-shaped rack is light-duty. Stack in moderation and keep the pile below the top of the uprights.
- Cover the top, not the sides. A sheet of metal roofing, a few boards or a tarp tied over the top protects the wood from rain and snow. Leave the sides open so moisture can escape.
- Leave space around it. Keep the rack a few feet from walls and fences so air can circulate.
- Use the oldest wood first. Load new wood at one end and burn from the other.
- Inspect each season. Check that the boards haven’t cracked or rotted and the blocks are still level.
How long does firewood take to dry on a rack?
Most freshly split hardwood needs 6 to 12 months (often longer for dense woods like oak) to reach a moisture content below about 20%, the level generally recommended for clean burning. Splitting logs before stacking and placing the rack in a sunny, breezy spot speeds things up. An inexpensive moisture meter takes the guesswork out of it.
Final thoughts
This concrete-block firewood rack is one of the cheapest and simplest backyard storage projects you can build. It keeps your wood raised, ventilated and easy to reach all winter long. Save this idea for your next weekend project and enjoy cleaner, warmer fires.
