Wood Rot Repair

Rot only spreads while there is moisture to feed it. We find how far it has gone, cut back to sound wood, fix the water problem and install new treated lumber, bracing and connectors. The repair is sized to the damage, from a small patch to a full replacement of a section.

Questions

Common questions

Will the rot spread?

Only if moisture remains. We fix the source as part of the repair.

Can you save partly damaged wood?

If it is sound after cleaning and drying, yes. We probe to decide.

Do I need new subfloor?

If it is soft or stained through, replacement is usual.
