Allen Clough, the owner of 21st Century Sweep, has been wonderful to work with. He is very knowledgeable about the chimney business and was able to explain (in simple terms) what was needed for my chimney to be repaired. He referred me to excellent resources and spent extra time answering my questions. He went above and beyond to make my fireplace look nice and included many things at no extra charge. He is a kind man who knows his stuff! I would highly recommend his services to anyone.
