The technician was efficient and thorough, and he provided very helpful information and explanations throughout the process. I enjoyed the experience and learned a lot, and now we have good information on which to base our decisions regarding servicing our chimney. I do not know how the service compares to that of other companies in terms of price because I did not check other companies. (I just went by the BBB rating of A+ and the recommendation of a realtor.) However, the information and service we received was well worth the money! And he technician (David) was very nice and enjoyable to work with.
