Here is something that seems to be so basic in stone siding installs that no one ever asks it until they get into the situation.
“Where do I start my stone? Top down or bottom up?
Well what I can say is there really isn’t a right or wrong way to do it as long as they stick. The trouble with installing in a fashion that is unconventional is that you will have too many variables to look after. If you are doing the entire wall it may be a little easier, reason being is that you can hide some mistakes either near the ground or near the eves. If you are installing stone veneer as a wainscoting then it would make sense to start top down.
Let me explain, most times if you are only doing the first 3 to 4 feet up the wall you are going to use a ledge to separate the 2 types of siding. Well you want to make sure that your stones are parallel with the ledge. If you install your ledge and then start on the bottom and work your way up, you will likely have a disaster if you don’t snap a chalk line to keep you straight. If you use the foundation as your check to keep the stones straight the results will be disappointing. Take a read on this site it has some opinions on where to start.
The only one that made sense to me and I think everyone was missing it. Start with the corners first. Then decide where you want to go from there. Bottom line there is no wrong way as long as the walls don’t leak and the stone looks good.
