Dry rot in basement outside wall
2x4 studs crumbling behind drywall. No water stains on drywall. Bought house and lived here 4yrs. How to know age of dry rot?.. is it possible there was leak over 4yrs ago and drywalled but and parged block foundation outside (appears to be bulging outside)
2x4s struts crumble and shrunken ckose to 50% ....
Would this be recent or possibly over 4yrs
Pls need advice. Thankyou
