What Causes Timber Decay?

Timber decay is typically the result of prolonged exposure to moisture. When timber becomes persistently damp, it creates the ideal environment for fungal spores to germinate and grow. The two main types of timber decay are:

• Wet Rot: Occurs when timber is in constant contact with moisture. Common in areas with leaking pipes or poor ventilation.

• Dry Rot: More serious, dry rot can spread through timber, masonry, and even behind plaster, often going undetected until significant damage is done.

Common Timber Infestation Culprits

Timber isn’t just vulnerable to fungi—it’s also at risk from insect infestations. The most frequent offenders in London properties include:

• Common Furniture Beetle (Anobium punctatum): Also known as woodworm, these insects bore into softwoods, leaving small exit holes and fine dust (frass).

• Deathwatch Beetle: Prefers hardwoods and is often found in historic buildings. They thrive in damp conditions and can cause significant structural damage.

• House Longhorn Beetle: Predominantly found in southern England, this pest attacks roof timbers, especially in modern buildings with poor ventilation.

How to Spot Timber Decay or Infestation

Here are the signs that could indicate timber problems in your London property:

• Crumbling or cracked timber surfaces

• Musty odours, especially in basements or loft spaces

• Flaking or discoloured wood

• Visible fungal growth or mycelium strands

• Fine dust (frass) beneath timbers

• Small round holes in wood surfaces

If you notice any of these symptoms, it’s important to arrange a timber survey quickly. Drysolve Surveying can help diagnose the issue accurately and recommend long-term solutions.

Prevention Strategies Every London Property Owner Should Know

✅ Control Moisture

Keep timber dry by addressing leaks, rising damp, or poor drainage. Ensure your property's ventilation is adequate, especially in crawl spaces, basements, and lofts.

✅ Regular Inspections

London’s climate and building styles make many homes prone to hidden dampness. A routine timber survey helps catch problems early—before they become costly.

✅ Timber Treatments

Professional treatments can eradicate active infestations and prevent new ones. Drysolve Surveying can recommend suitable preservative applications or treatments following a thorough inspection.

✅ Consider Ventilation Upgrades

Poor airflow is a leading contributor to moisture build-up. Installing passive or mechanical ventilation systems can make a significant difference, especially in older properties.
