![]() The other problem with the design is that, while it lasted however long (I doubt that building has been there for 50 years, but I get your point), because of the design what has to happen now is quite drastic. ![]() Greg- I agree that it's really not "underdesigned" structurally with the wood they used, but probably is if replacing with today's PT. I'm not sure that you could install and fasten to the interior without doing that. Well- to start, the only way to repair the cantilevers as they exist would be to remove the flooring to the interior to allow you to bring the new joists in to the house by some ration- 3-1 was the old standard. Re: Repairing/Sistering Cantilevered Deck Joist I would love to just cut all the joists back and install a ledger/beam/post, but not able to do it because of windows/decks below, so I'm stuck repairing or replacing this one.Īlso need to figure out whether the chimney was built cantilevered out over the deck, or if the put all the deck-boards down and built the chimney on top. Most of the joist only have 1/2" or so of rot along the tops, but there is one or two that are rotted 1"-2" down.The joists are untreated 2x12s the cantilever 8' out from the top plate. I'm just trying to figure out the best repair solution. I know I need to be asking an engineer, because no one here wants to give structural advice over the 'net, and I don't blame ya'll. I don't know who thought that building decks/balconies this way was a good idea, but I'd like to kick 'em square in the nether regions.Īt what point does it go from being able to sister a joist to actually having to remove and replace the entire joist or cut 'em all off and install a ledger/post/beam?
