Customers say: True professional
"I initially contacted Franco for a chimney inspection and cleaning. He discovered that our fireplace chimney needed a bit of work as expected, but more importantly the furnace chimney did not have a liner whatsoever. He came back the next day after gathering supplies to complete the job. He explained everything from start to finish and provided before and after photos of the work. I would absolutely recommend Franco to anyone."
