A few months ago we discovered termites in our house. We immediately had our home treated and today, taking advantage of the warm days, I started repairing the damage.
I cut the drywall away in the area of the damage, tore out the damaged
wood and replaced it with new.
The damage was to a non-load bearing wall so I was able to make
a new header with a length of 3/4" plywood sandwiched between
two 2X4's. Tomorrow I'll repair the drywall and it should be
as good as new.
