I used Arête for some recent water damage in my condo and they did a great job! The plaster walls look much better(more smooth and even), even before the water damage occurred. The ceiling was peeling /discolored and the walls were bubbling out due to the water. They removed the damaged areas, applied skim coating over the plaster, sanded, primered, and painted. I would recommend them for any construction or renovation job. See my earlier post about my bathroom renovation last year — they did an excellent job!
