Cinderfella responded quickly to our call for help due to a blocked chimney which had extinguished our gas. They came out the same day, which was a Saturday, and removed the blockage (a squirrel's nest and the pesky skirrel that had decided to make its home in our chimney). They came back to install a new chimney liner the next working day. They knew what they were doing and were pleasant and friendly to deal with. I would certainly use them again.
