I can't help with a contractor, and you may have more in-depth
experience than I do, but I will relate my experiences with flat
plaster and pebble dash stucco.
1. flat plaster. I had specified veneer plaster over USG diamond
board - everything looked like it went in according to the plan, until
the recessed art lights grazed the surface vertically. It turned out
the subcontractor had not applied the correct thickness of veneer
plaster, so that at the joints it was thicker and with horizontal
joints every 4 feet above the finished floor, the wall was not
actually flat, but had bulges at the joints of the board beneath. In
hindsight, I should have watched the number of bags of plaster and the
quantity that was being used. The veneer plaster should have been a
uniform 1/8" thick, and it was very hard to tell how much plaster had
been applied by just looking. We did not measure the thickness until
it was too late, but we could easily have compared the volume of
plaster (in the number of bags of raw material) and the square footage
of coverage. This may not be the exact situation you are dealing
with, and simple patches in flat plaster should not be too difficult
or challenging for a true plasterer.
2. pebble-dash stucco. Patching this material requires close
attention to the size and shape of the pebbles, gravel, or sand (and
sometimes boulders - actually just large rocks - aka boulder-dash).
If it was originally applied with a sprayer, or flinger, or a trowel,
that is probably the way it needs to be applied in the repair. You'll
want to remove or re-attach any loose or degraded sections, depending
on how badly damaged it is. If you think you will have to replace
entire sections, you'll want to require samples and not rely on the
subcontractor's claims and promises that he or she will be able to
match adjacent or nearby panels without practice. To some extent, you
may want to consider wholesale replacement so that matching exactly is
not as important, though in the spirit of maintaining all the original
material possible, you may prefer slightly mis-matched repairs.

The interior plaster work is entirely flat plaster, patch and repair work.
The Exterior stucco is a pebble texture stucco and may need to be replaced, I need help to determine that.
Thanks you for any help.

Mr. Stephans. I am based in the Chicago area and could provide some recommendations for Chicago and Wisconsin-based plaster contractors/conservators. However, first, is this mainly/entirely flat plaster or is this decorative plaster? And, what's the extent of the work? And, is this simple patchwork or significant restoration/replication? What about the exterior stucco? These questions will definitely inform the list of recommended conservators and tradespeople I would recommend.

I need a qualified contractor to do interior residential paster work in Evansville, Wisconsin. I also need a qualified contractor to do exterior stucco work in Evansville, Wisconsin. These are two different projects, both historic residences in a local Historic District, which is listed on the National Register of Historic Places.
