I have some termite damage to a select number of diagonal 1″x6″ subfloor boards. I could just replace the affected boards but I would really like to replace the whole subfloor with 3/4″ treated plywood tongue and groove.
What is the exact proceedure for removal and replacement of the subfloor?
1. Do you just cut into the old subfloor at the wall edges?
2. Is treated plywood ok for the subfloor in the interior of a house?
3. Do you lay the 4’x8′ sheets of plywood perpendicular to the joists and staggered?
