I have run in to a snag trying to “plumb” the front of my (future) home. The house is a 1860 balloon frame, two story structure with the original shiplap siding. The gable end of the house leans back about 5 inches out of plumb.
The original plan was to fir out the wall and put up some new wood siding – leaving the original siding on to keep everything from moving. (forgot to mention – have already taken care of the foundation problem that caused the lean and have run plumb sister studs on the interior).
I started by running 2x up each corner of the front of the home – shimming and blocking along the way so that I have two parallel, plumb corners on the house. My intention was to run cross bracing or nailing strips horizontally and vertically.
Starting from the bottom of the house – I began to sun sheathing over the 2x “frame” that I created. Around the same time I started to think about fire blocking and the chimney that I created on the outside of my house by building inspector stopped by enroute from another inspection down the road.
We came up with two problems that I created – the concealed space on the exterior of the house and a possible vapor barrier nightmare.
Anyone have an idea how I might prevent this? Removing the old siding is the easiest, I guess – but I hate to remove anything that helps hold her together. I have more than a few studs that run 3/4 of the way up the house and stop. It seems to me that there has to be a way to address both the moisture and fire problems.
Thanks in advance.
