My home is older and doesn’t have weeping tile. Should I dig up the walls to add weeping tile now?

I am not an expert but I always say, if it isn’t broken, don’t fix it. If you have a wet basement I suggest trying other fixes before trying to install weeping tile. Make sure for instance, that the slope drains water away from the home. Also cover low basement windows with a plastic cover so water doesn’t get in that way. Be sure to check the downspouts. Finally you also may want to add an outside sump. In my opinion don’t try to fix weeping tile until all the other less expensive options have been tried.
