i want to reside a 25 yr old garage. the bottom of the 1/2" celotex sheathing sucked up some h2o over the years, and looked like this when i took off the old siding.
i've decided to cut off the bottom 2' all the way around and put on some pressure treated 1/2" OSB in it's place. i've noticed there is some water damage throughout the celotex...you know, a splotch here or there.
my q's are:
- is my 'plan' the correct way the best overall way to do this job?
- do i have to replace all boards that have water stain on them, or can i leave the partially (but still intact) stained boards up and re-side over them once i replace the lower pieces to seal up the bottom?
thanks so much!
