We had the small leak in one baseboard heater in the basement. The leak
traveled across the floor and soaked a 10' section of the baseboard. I
bought a new baseboard a few weeks ago and left it in the basement. I
took the old one off the other day and I painted the new one.
Under the old baseboard, there was some mold forming on the sheetrock. I
am letting it air dry for a few days before I put on some alcohol-based
Killz (shellac). When I do that I will put a second coat on the
baseboard so that I can install the new section next week.
