I have a Tudor-style house built in 1976 with stone (real), stucco (pressed wood), and wood trim. There are places that need patching and probably some trim boards at the bottom that need replacing. We also have an old intercom system that no longer works. I'd like to have that removed and fill in that stucco area. Any suggestions on how to get this done right? What should I look for when I get estimates? Is oil or water-based recommended?
