We have been doing siding installation out of Garfield for 25+ years. Guttenberg is 9.1 miles south-east of the shop, in Hudson County — well inside the area we work in regularly rather than the edge of it. Either way we still answer when you call about the job two winters later, which is the part that actually depends on being local.
A siding job is stripping the old material off, looking at the sheathing underneath, putting the weather barrier on properly, and hanging new panels with the trim and corners to match. The panels are what you see; the wrap behind them is what keeps the wall dry.
The densest county in the state. Row homes, brownstones and multi-family buildings on tight lots, much of it pre-war, with shared or near-shared walls and very little clearance between buildings. What is behind the siding matters more than what replaces it. Older walls were built before house wrap was standard, so the tear-off is often the first time anyone has looked at that sheathing since it went up.
We tear off rather than cover over, because going over the top means nobody inspects the wall and you lose the one chance to install the barrier correctly. Rot is photographed and priced per sheet before we touch it, and the site is swept at the end of every day rather than at the end of the job.
