Showed up on time; thorough; cleaned up after himself; pleasant and knowledgeable; good communicator and most important, KNEW what he was doing. My furnace wasn't staying lit due to debris in the flue but Bob cleaned it all out and screened it and now it is running just fine. You may not know what a chimney sweep does but when you need one, Bob Fisher is the best! Plus he does other services. I recommend him without hesitation.
