Dry rot treatment
Careful dry rot investigation, moisture-source correction and defined remedial scope.
Why diagnosis matters
Treat the cause, then repair the damage
Suspected dry rot requires prompt, careful investigation because growth can extend beyond the first visible area. The source of moisture and the true extent must be established before repair.

Common questions
About dry rot treatment
Can dry rot spread through masonry?+
Fungal strands can travel across masonry to reach timber under favourable damp conditions, which is why extent and moisture control matter.
Can I remain at home?+
This depends on extent, access, dust controls and treatment. We provide project-specific guidance.
Is all brown cracked timber dry rot?+
No. Visual similarities exist, so identification should consider the full set of signs and conditions.
