For years my wife and I were told by so called Fireplace Repair "EXPERTS" that we could only use the fireplace again if we had a venting fan system installed for thousands of dollars. Scott, came out on time, provided us a completely free inspection, and wrote an honest estimate. We hired him! When the parts arrived, in less than one day, Scott had our fireplace back up to code, and working just fine! Well Don On Top Service. Harvey Warshaw, a more than satisfied customer.
