I am working on replacing decking and found a couple of rotted joist I decided to replace as well.
The joist size is 2x8-12. I purchased the replacement joists however when I took one rotten out and compared with the new one, it turned out the new one is 1/4" wider. The label on both old and new joists says 2x8-12, but the exact width of the old one is 7" and new one is 7 1/4". Did I get wrong product? The old deck may be 10 years old -- is it just result of the wood shrinking over years? If so does it mean I can't replace a few joists and should do it for all of them? Technically I could cut off the extra piece but if it is shrinking, then it will become uneven in a few years.
Any guidance would be much appreciated
