I have a ninety-year-old house which means it doesn't have any drywall. It's all plaster and brick. So I had to find somebody who knew how to work with plaster walls. I found Paul Riggs of Worldgate Plaster & Stucco. He and his crew knew what they were doing. I was surprised when they finished the plaster in one day. The plaster was at least two or three inches thick and they went all the way down to the brick. Then each layer was applied in order. It was an excellent job and I feel like it was an excellent price for what I got. Five stars for Worldgate Plaster & Stucco.
