A roaring fire is one of life's simple pleasures, warming the home, creating ambiance and offering a reliable source of heat during colder months. But not all firewood is the same. Using low-quality firewood can result in frustrating fires, inefficient burning and even long-term damage to your fireplace or stove.
In this article, we’ll look at five tell-tale signs you’re using low-quality firewood, how to remedy the situation, and how to ensure you’re choosing the right wood for maximum warmth and efficiency.
1. Your Firewood Feels Damp or Heavy
One of the most obvious signs of poor-quality firewood is that it feels wet or unusually heavy. Good firewood should be well-seasoned meaning it’s been allowed to dry out for at least 6–12 months after being cut. Wet or “green” wood contains high levels of moisture, making it difficult to light and sustain a fire.
The Fix: Invest in a moisture meter to test your firewood. Seasoned wood should have a moisture content of 20% or less. If your wood is damp, store it in a dry, ventilated area off the ground and covered on top (but open on the sides) to allow proper air circulation. Better yet, buy properly seasoned or kiln-dried firewood from a trusted supplier.
2. You Notice Excessive Smoke
A fire should produce minimal smoke once it’s burning steadily. If your fire is emitting thick, dark smoke, it's a strong indicator that the wood is either too wet or of poor quality. Smoke not only wastes energy but also contributes to creosote buildup in chimneys, which can pose a serious fire hazard.
The Fix: Always burn hardwoods like oak, ash, or beech that are properly dried. Avoid softwoods and woods that haven’t been seasoned. If you’re noticing excessive smoke, stop using that batch of wood and replace it with a higher-quality option.
3. You’re Constantly Struggling to Keep the Fire Going
If your fire keeps going out, the issue may not be your technique—it might be your fuel. Low-quality firewood often lacks the density and dryness needed for consistent burning. Unseasoned or soft wood burns out quickly and doesn’t produce lasting heat.
The Fix: Switch to hardwoods that are dense and properly dried. Hardwoods burn longer and hotter, making them ideal for home heating. Kiln-dried wood, in particular, offers exceptional burn quality and easy lighting.
4. There’s a Strong, Unpleasant Smell
All firewood has a natural aroma, but if your fire emits a sour, musty, or acrid smell, it's likely due to mould, fungus, or chemical contamination. This can happen when wood is improperly stored or if it's been exposed to painted or treated surfaces.
The Fix: Never burn painted, stained, or chemically treated wood, as it can release toxic fumes. Ensure your firewood is stored correctly—off the ground, away from moisture, and covered from rain. If you detect any strange smells, discard the affected wood immediately.
5. You See Mould, Fungus, or Insects
Visibly mouldy or infested wood is a clear sign of poor quality. Not only does this type of firewood burn inefficiently, but it can also introduce pests into your home and damage your fireplace or stove.
The Fix: Inspect your firewood regularly for mould, fungi, or insect activity. Use a dry, ventilated shed or covered wood store to keep your logs in peak condition. For peace of mind, consider buying kiln-dried firewood, which is treated at high temperatures to eliminate moisture and pests.
What Makes Good Firewood?
To ensure you’re getting the best burn, look for:
- Kiln-dried or seasoned hardwoods like ash, oak, or hornbeam.
- Low moisture content (ideally under 20%).
- Clean-cut logs, free of mould, dirt, or pests.
- A reputable supplier who can certify the wood’s origin and drying process.
Avoid firewood that’s freshly cut, soft, or unlabelled it may be cheaper up front, but it can cost more in the long run through damage, inefficiency, and added maintenance.
The Bottom Line
Using high-quality firewood not only improves your home’s warmth and comfort but also protects your fireplace and keeps your household safe. Poor firewood wastes time, energy, and money. By knowing what to look for and what to avoid you can ensure every fire you light burns beautifully.
