What Our Customers are Saying…
Upon your recommendation I recently had my oil burner chimney repaired/replaced by Guaranteed Chimney. They increased the size of the flue to seven inches from four inches. The negative draft is now five.
This company was very professional and reasonable in their pricing. I highly recommended them.
