Scott did a wonderful job of the California knockdown ceilings and all surfaces, both horizontal and vertical. He managed to control most of the sanding dust although the cleanup at the end of the job was not quite what I had expected. With a little effort on our part however, we were back to normal in short order. I would hire Scott again - his pricing was very competitive, and he was reliably on schedule. I am comfortable doing drywall and finishing myself, but I usually have a professional do the taping and mudding to save on time and mess, and Scott filled the bill perfectly.
