Does anyone know a good and reliable mason in the Groton area? (alternately, a general contractor who appreciates old houses?) We've been trying to have work done on rebuilding the foundation of an unfinished room at the back of our house. The GC we've been trying to work with seems really good, but he's had trouble getting a mason - they don't show to look at the site, or once they do show they don't return his calls. We've been working on this since May and need to get the foundation done so we can install a first floor bath before I have some needed knee surgery. Any recommendations would be appreciated. Thanks!
