We had our chimney cleaned today by Steve-our-plumber, who moonlights as a chimney sweep on weekends. It has been a while since we last needed his services, so Lisa showed him the new wider carport and other improvements, and also discussed with him some changes she's planning to do on her own. ("But if I mess it up, we'll call you and you'll earn some money cleaning up my mistakes.")
We do have the chimney swept annually. We use the fireplace heavily during the winter, and chimney fires are no joke.
