My 5-yr old house exterior is hardi-plank siding. But at the bottom, it's a
piece of wood plank covering on concrete foundation. The plank is about 1-2
inches above yard ground. Use fingers to check from bottom, the wood plank
is not tightly attached to the concrete. Somewhere around the house, I can
feel quite hollow.
Should I seal the gap between the wood plank and the concrete foundation?
That would be a hard job if yes.
