Soft, cracked or cuboidal timber
Loss of strength and characteristic cracking can indicate fungal decay and needs investigation of the moisture source.
What a useful investigation should establish.
A proposal is more useful when it explains the likely cause, the evidence, the affected construction and why a particular repair is being considered.
- Locate leaks, condensation, blocked ventilation, damp masonry and ground moisture affecting the timber.
- Identify the timber, decay pattern or insect evidence and assess whether activity is current.
- Probe and inspect accessible sections, including vulnerable bearings and concealed interfaces where justified.
- Escalate significant section loss or load-bearing concerns for structural assessment and design.

How the repair may be approached.
Remove the moisture source
Repair defects and improve ventilation so timber can return toward a safe equilibrium condition.
Retain sound timber where possible
Not every historic flight hole or stained surface requires chemical treatment or wholesale replacement.
Targeted authorised treatment
Where treatment is justified, the product must be authorised for the intended use and applied in accordance with its label.
Repair or replace damaged sections
Local reinforcement, resin repair or replacement depends on extent, location and structural design requirements.
Important limitation
Spraying exposed timber without resolving moisture is unlikely to provide a durable outcome. Old insect holes do not necessarily indicate current activity, and structural timber repairs should not be specified without understanding load paths and remaining section.
