When calling to make an appt, Jennifer was pleasant and willing to make sure they accomodated my schedule. When they came out – they called to say they could be there earlier. Very knowledgable and informed me of where any problems were showing on a diagram – I had a clr log from target and he stated this was a very good log to use (instead of trying to upsell me). He was very effecient and careful not to make a mess and put everything back in fireplace as he found it. Very pleased with level of knowledge and customer service. Highly recommend!
