Professional Diagnosis, Repair & Long-Term Protection

Timber preservation is the process of protecting structural and non-structural timber from decay, rot and insect infestation. Problems such as woodworm, wet rot and dry rot can significantly weaken a building if left untreated, particularly where timber has been exposed to persistent moisture.

Effective timber preservation always starts with accurate diagnosis. Treating timber without addressing the moisture source will result in repeat failure, unnecessary cost and ongoing damage.

Why timber preservation matters

Timber forms a critical part of most buildings — floors, joists, roof structures, lintels and internal joinery all rely on timber remaining dry and sound.

Where moisture is present, timber becomes vulnerable to:

  • Fungal decay (wet rot and dry rot)
  • Insect infestation (woodworm)
  • Structural weakening
  • Expensive secondary repairs

Early assessment and targeted treatment preserves as much original timber as possible and keeps repair costs under control.

What causes timber decay and infestation?

Timber problems almost always stem from excess moisture. Common contributing factors include:

  • Rising damp at floor level

  • Penetrating damp from external defects

  • Condensation in poorly ventilated areas

  • Plumbing or roof leaks

  • Blocked sub-floor ventilation

  • Bridged damp proof courses

Unless the moisture source is identified and resolved, timber treatments alone will not provide a lasting solution.

Wet rot in timber

Wet rot occurs when timber remains damp for prolonged periods. It is commonly found in:

  • Roof timbers affected by leaks
  • Floor joists near damp walls
  • Window frames and external joinery

Typical signs of wet rot include:

  • Darkened or bleached timber
  • Spongy or soft texture
  • Long cracking or splitting
  • Localised decay close to moisture source

Wet rot does not spread through masonry, but it can severely weaken affected timber if ignored.

Dry rot in timber

Dry rot is a more aggressive fungal decay caused by Serpula lacrymans. It thrives in damp, poorly ventilated environments and can spread beyond the original moisture source.

Common indicators include:

  • Cuboidal cracking in timber

  • Dry, brittle wood that crumbles easily

  • Musty, mushroom-like odour

  • White or grey cotton-wool growth (mycelium)

  • Rust-coloured dust from spores

Dry rot can spread through masonry and plaster, making early diagnosis critical.

Timber treatment & preservation services

Our timber preservation process is designed to be targeted, proportionate and evidence-led.

1. Timber & damp survey

We assess:

  • Timber moisture content

  • Extent of decay or infestation

  • Structural integrity

  • Presence of salts or fungal growth

  • Underlying damp sources

2. Repair vs replacement assessment

Where possible, sound timber is retained. Only timber beyond economic repair is removed and replaced.

3. Targeted treatment

Remaining timber is treated with professional-grade fungicidal and insecticidal preservatives to prevent further decay or infestation.

4. Timber replacement (if required)

New timber is pre-treated and installed to current standards, ensuring durability and long-term protection.

Damp proofing and timber preservation go hand-in-hand

Timber problems rarely exist in isolation. Damp conditions provide the environment fungi and insects need to thrive.

Long-term timber preservation often requires:

  • Damp proof course repairs or installation
  • Removal of bridging
  • Improved ventilation
  • Repairs to external defects
  • Moisture management strategies

Treating timber without addressing damp leads to repeat failure.

When should you arrange a timber survey?

You should seek professional assessment if:

  • Damp has been identified near timber

  • Floors feel springy or uneven

  • Woodworm activity is suspected

  • Musty smells are present

  • You are buying or selling a property

  • Timber decay has been flagged in a survey

Hidden timber decay is common beneath floors and in roof voids and should never be guessed at.
