Here are two pictures of the house next door during application of the vinyl siding.    

Note that there is no barrier wrap (e.g., Dupont Tyvek®, etc.) on the house.  For some reason, the house was not wrapped prior to the siding going up, so it is being applied as the siding is put up.  

The siding on the other side of the house was put up with no barrier wrap under it…and had to be torn down and put up again after applying the wrap.

It took about two days to put all the siding up.
