We decided to convert our gas fireplace back to wood burning. Unknown to us we needed to reline the chimney, replace the damper and put in a stainless steel flue. This required breaking a hole in the chimney from the back, the back of which had just been renovated for our new dining room. Carleton came in and completed the work in 4 days. The work was done timely, with precision and with the highest quality. Notably the crew carried out the work with utmost care. They erected a tent around the fireplace, made as little noise as possible and created next to no dust at all. I strongly recommend them. You can be assured your fireplace will never be a cause for concern.
