I have an older deck that has a wide (approx 25 feet) unsupported span. The railing on the deck seems to be pulling outward, probably due to planters on it, and general heavy usage. The underside of the deck has fairly good support via two by eights. It appears that the railing is attached via nails only.
I need to figure out how to reattach the railing in a way that won't come out again. My first thought is replace the nails with bolts, but I'm not sure if I need to also replace the railing's wood. Would bolts work? How do I determine if I should replace the wood?
