Greetings I’m doing some trim and paint work on the south side of our house following a bathroom remodel. I have found some rot in the upper section of our siding. I assume I need to replace the board. I also assume i need to start on one end of the wall and work my way to the problem area, replace, then reinstall so pieces overlap (?). Here is the existing z-bar Sound right? Anything else to consider? Just grab the cats paw and go? Thanks.
