We called Hoffman Bro's first because they deal with both, and they charged us ~$300 to tell us the same thing as Spire and suggest we call a chimney sweep to check the flue pipe for blockages. We couldn't find a chimney sweep that either could be booked within the month to inspect and give us an estimate, and if they could be booked in that time frame they didn't understand the problem we described and wanted us to fork over hundreds to inspect and sweep our flue. Luckily, an acquantance gave us Crestside Ballwin's number. The receptionist called Dave over to learn about the problem and within a minute he figured that the roofers we had over a few weeks ago probably botched the install of the new flue pipe cap. They had a tech come over two hours after I called and sure enough that was the problem. Anyhow, these guys were solid for us, I'm super thankful we found them.

We have a service plan with them (Giant rip-off) but they wanted to charge $$ to come out and diagnose the problem and wanted to be paid in advance.
