Shop wood rot repair epoxy, consolidants, fillers, repair sticks and borate treatments for stabilizing and rebuilding damaged wood components. Assess the remaining wood and project requirements before choosing repair rather than replacement, especially for structural components.

Remove loose or failed material and determine whether sound wood remains. Structural, safety-critical or extensively deteriorated components may require professional assessment or replacement rather than a cosmetic repair.
A consolidant can firm porous wood before an epoxy putty or paste rebuilds missing profiles. Select compatible products and observe cure, sanding, coating and moisture requirements.
Correct water entry and persistent moisture before repair. Where appropriate, a borate treatment may complement the system. For other bonding work, compare epoxy adhesives.
When should rotten wood be replaced instead of repaired? Replace or obtain qualified advice when deterioration is extensive, load-bearing capacity is uncertain, or the moisture source cannot be corrected.
Can repaired wood be painted? Many cured repair epoxies can be sanded and coated, but the finish must be compatible and the product directions followed.
What is the usual repair sequence? Correct moisture, remove failed material, treat or consolidate where appropriate, rebuild with a compatible filler, then sand and finish.
