flue lining, chimney lining.
We have an 1860 brownstone. The flue from the garden level fireplace was never lined. When our tenants recently had a fire, our upper duplex filled with smoke. We have had several different firms come and give estimates, but I’m not sure who to go with. Also, what size liner to get: 7″, 8″ or 9″. The fireplace/firebox is apparently larger than normal and a couple people said 9″ is the way to go, but that would likely mean moving or removing the wall of the unused flue next to the one in question, and a huge mess and a lot of work. Also, what’s the best material? Double-wall? Smooth wall? Should it be insulated? We’re in Park Slope. Would greatly appreciate any comments from personal experience. Oh, the opening at the roof is about 9″ x 9″ but if you look down, the flue gets smaller, and then bends to the right. The other idea someone had was to just put a 6″ liner in, and have a fan on the roof. The fan costs $1500 – $2000, and increases the cost of the job significantly. But, it would likely be far less of a mess to run such a small tube down the flue. I’m disinclined to go the fan route because it’s just something else to break and worry about, and what if the tenants forget to use it or it breaks mid-fire? I want the fireplace to be idiot-proof. Thanks for your input.
