Excellent start. Sent the chimney sweep who was prompt, efficient and identified issues clearly. Visit to the showroom went well, too: identified model required. Problem arose when estimate received for it was higher than expected. Issue was the price of the aspirator that was needed in addition to the new fire. Only explanation was the model recommended was the basic and it could have cost a lot more. Asked for website of manufacturer but was given a name that Google wont find. Promised 'material' by email. After Xmas will start looking elsewhere. (Everyone is very nice, polite and pleasant to deal with.)
