Hello my name is James and I am a new member. MY trade is auto repair and up until about a month ago I was sacred to death of home repairs but am slowing making friends with the hammer!!
Anyway, My chimney was repaired about 4 years ago but unfortunately has started to leak again. Since the chimney is not used I was thinking of removing it. The inside is a brick face the rest is wood all the way up and it is attached to the side of the house. I was thinking of having a professional do the job as I am an amature. What do I expect to pay..?
James, that chimney sits in a valley. It's not impossible to provide a proper flashing that will make it serviceable. The money you spend to remove and repair the roof deck could be spent to make it functional. I'm thinking resale value is why I'd say fix it. A fireplace that can't be used is not a asset of the structure. If you need to find a qualified installer check at the local roofing supply houses not the apron store for a good company.
If you're set on getting rid of it. Remove it from the fascia board up and turn that area underneath into patio storage.
Cost? Check with a local contractor that does room renovations or additions for a local cost.
You could get rid of the top of it, because it is a poor design, but also keep the bottom portion. Extend the roof a bit, And install a vented gas fireplace that vents out the wall, and keep your ambiance of a fireplace.
