Wood & Its Moisture Level: A Complete Guide
Recent data from the Guild of Master Chimney Sweeps reveals that incorrect wood moisture levels contribute to over 30% of chimney-related issues in British homes. For Cambridge’s historic properties, particularly those in conservation areas, understanding proper wood moisture content is crucial for safe and efficient heating.
Understanding Wood Moisture Content for Local Properties
The unique climate of Cambridgeshire, with its typical British oceanic weather patterns, presents specific challenges for wood storage and seasoning. Our extensive experience serving properties across Cambridge, Ely, and surrounding areas has shown that local weather conditions significantly impact wood moisture levels.
Types of Wood and Moisture Content
Different wood types available in Cambridgeshire have varying moisture levels:
Kiln-Dried Wood
- Moisture content: 8-20%
- Variation depends on:
- Initial drying process
- Storage conditions
- Exposure to local weather
Green Wood
- Moisture content: Often exceeds 30%
- Common sources:
- Garden maintenance
- Local landscape work
- Tree surgery operations
Seasoned Wood
- Traditional drying method
- Typical British seasoning time:
- One year per inch thickness
- Local humidity rarely allows below 16%
- Cambridge’s climate may extend drying time
Impact on Your Chimney System
According to HETAS guidelines, burning wood with high moisture content can:
- Reduce heating efficiency by up to 20%
- Increase creosote formation
- Accelerate chimney deterioration
- Risk chimney fires
The Science Behind Moisture Content
When burning wood with 20% moisture:
- 20% of heat energy wasted
- Reduced fire temperature
- Increased smoke production
- Higher risk of tar deposits

Frequently Asked Questions
How can I tell if my wood is properly seasoned?
Use a moisture meter to check levels are below 20%. Look for splits in the wood ends and listen for a hollow sound when pieces are knocked together.
How should I store wood in Cambridge’s climate?
Store wood off the ground in a well-ventilated shelter, protected from rain but allowing air flow. Consider local weather patterns when choosing storage locations.
What’s the best wood for period properties in Cambridge?
Hardwoods like ash and oak are ideal for traditional fireplaces in period properties, providing longer burn times and higher heat output.
Storage Tips for Local Conditions
Given Cambridgeshire’s weather patterns:
- Elevate wood storage off damp ground
- Ensure good airflow
- Protect from prevailing winds
- Consider covered but ventilated storage
