A few people asked me to post the chimney repair recommendations I received, so here they are:

3 people recommended  American Chimney and Fireplace ( https://americanchimneyandfireplace.com/index.html) (this place received the most enthusiastic recommendations of the bunch)

2 people recommended Comfort Living Fireplaces, which both noted is family-owned

3 people recommended Hearth and Home Furnishings in Zelienople

2 people recommended The Fireplace and Patio store. One person noted that they only install logs, but do not fix the gas line

2 people recommended Ed's Woodshed

1 person recommended Black Knight Chimney (for chimney work, not sure whether they do gas logs)

1 person strongly suggested NOT using Advance Chimney Sweeps

Hope this is useful,
EM
