Master Services does not stand behind their work!! They made a chimney cap for us that didn’t fit according to our contractor which will cause it to take in water on the inside. It wasn’t made long enough around the outside edge. When our contractor tried to explain this to the General Manager, he was told that “they made the chimney cap just like the old one”. Who does that?? Who just puts up any old thing if they can tell it needs improvement?? Our chimney is at least 35 feet up in the air. There is no way we could possibly tell if their work was good until our contractor told us. Also, we had to call them back recently to finish bolting it on because it wasn’t installed properly and started rattling really loud during a storm. Terrible experience with them. Would NEVER recommend them to anybody.
