Greetings,

I have a moist basement which has caused the joists (sistered 2x8s) to
mold and start to decay. The floor is still sound but I imagine the
joists will have to be sistered again in a number of years if this is
allowed to continue. What can I do to solve this problem? Is there
something (low cost?) that I can treat (spray?) the wood with?

Thanks,
William
