Removing a chimney

#Post
1

I am getting a new roof soon and I was wondering the pros and cons of getting the chimney removed at the same time. I’ve live in the house and have never used the open fireplace.
Pros - The house is 60 years old and maybe the mortar will not hold the chimney together if there is ever an earthquake in Whangarei.
- at some stage I’ll be renting the house out and I wouldn’t want the tenants to use the fireplace.
Cons - Possibly I’ll have to get council consent to have it taken down
- the house will look weird without a chimney
- people may be more reluctant to buy it in the future

Does anyone have any thoughts on the matter? Thanks in advance.

depends on what condition its in and where it is on the house.
if poor condition i would rip it out and get rid of the fireplace and the chimney.

unfortunately i have seen house reno's where they covered up the old fireplace and left the chimney there, which then becomes a big issue later on.

Well we have taken down 3 x chimneys in the past, easy as, We didn't get any consent, this was is the good old days,if you want to see the hearth and such inside then you just need to take the top off to under the roof line. If you want to remove inside then it,s a little bit more involved. Some of the old brickwork can stay inside the wall if you want, just box it up and good to go.

Check with your local Council. It probably won't need consent, since the Chch earthquakes they changed a lot of the rules.
But just depending on how far you are going, since you only mention ' removing a chimney' & not ' removing chimney & fireplace' & if the house is wooden or brick & if it's a part of the exterior.
Then I guess it's just removal down to roofline & cover over everything else.

I have a rental and did the same last year. Take chimney down to roof level and then get some zincalum from Bunnings , replace and then get on with your day.

It would seem logical to take down a chimney due to earthquake risk however some councils still want to clip the ticket for a consent to remove. Check it out first with your local council. It can have implications for insurance and reselling.

If you take it down to the roof line it preserves the options for a future owner who may want to use the fireplace for a log burner etc. They just need to run a flue up the existing chimney inside then go outside through roofing. This is good if your house has a beautiful mantelpiece etc that you want to save.

If you get a professional they will look after the Council consent etc though it wouldn't hurt to ring your Council and ask for the two scenarios
1 removing to roofline and
2 totally removing inside and out.

You do not need a consent to remove a chimney . Somretines it is an easy job if the chimney is a brick one with no concrete core , but some old State House chimneys were poured in sol;id concrete with just the above roof line plastered . Those are a bitch to remove as the are solid with reinforcing in them most times .
You often gain quite a bit of space in the room it is remmoved from

Thank you all for your invaluable replies. I’ll need to check if there is a concrete core to the chimney. If so I’ll leave the chimney where it is. I was just planning to remove the chimney to the roof line as I figured it would become too complex and expensive removing the rest of the chimney down to the ground. The fireplace inside is nearly flush with the inside wall so I’d not gain any extra space inside the living room by removing it.

I’m thinking about removing a chip heater as well, but I’ll start a new thread for that.

A chippie with a wetback that is still functioning? Or even without a wetback? No, no don't do it. So simple and easy to run, a bit like scooters that need a 'cough' of petrol to run, the chippies I have had experience with can use wood, little bits, coal if you can get etc. I would leave it, have the flue swept and don't use it but don't pull it out.

Thanks for the feed back. I’m still thinking about what to do with the wet back. The door (original 1960s model) is broken and I’d have to put in a new unit. It did heat water apparently but the previous owners didn’t use it after a pipe burst and water went through the ceiling. Consumer magazine said they were inefficient at heating, but I guess if there was free wood, inefficiency wouldn’t matter, although emissions would.
