Chimney

[stuart45]

The reason roofers get called in to do brickwork and pointing on chimneys in the private sector is that nowadays they are the only ones with ladders to go up and do it. It's the same with lead flashings. Traditionally it's the plumber that was trained to do the job properly, but it's hard enough for people to get a plumber out anyway and even less chance of getting one up on the roof.
When you work for a company the scaffold would be set up for the correct trades to come in. e,g, bricklayers to rebuild the stack, roofers to tile to it, plumbers to do the flashing.

That angle is somewhere between 1 and 2 degrees. When it gets to 20 you need to worry.

this is the other side of the chimney. I did notice these cracks about a year ago when the roofer came to remove and re cement the top of the chimney. I guess there was a miscommunication because I thought they had been repointed/ fixed at the time and it wasn’t until we got a better picture today I’ve realised they are still the same.

I’ve asked a brick layer to come and have a look in the week. I’ve sent him these photos plus ones from inside the loft. He’s not overly concerned and said he will diagnose better when he’s here but not to worry.

I guess my next question is would it be worth having this removed to the roof? Or could that cause more issues later on? I have no idea what would be the best

OP,
Dont remove the chimney stack - there are many good reasons for keeping stacks.
The above pic shows a few bricks that can be re-pointed - or they could be
carefully removed, cleaned & re-bedded. The whole stack needs to be correctly re-pointed.

Hopefully, the flues have been swept, and there is ventilation in the fireplace blocking?

Thank you for your reply. There’s no air brick so the person I spoke to yesterday said we can put one in. The flues haven’t been swept that I know of. The chimney hasn’t been in use for almost 30 years. We’ve owned the house 2 years but it’s the house I grew up in so there’s lots of projects that were started and never finished

Hi sorry to bother you. Recently our new neighbours mentioned that their chimney leans in a little. This got me looking at ours and im wondering if it needs looking at? Is it normal for them to lean a little? It’s a 1960s build with the fireplace inside bricked up but not removed.

They lean, and its generally not a problem. More important to get the flashing right, which appears to be the vase.

OP,
Lack of through ventilation in flues esp. soot dirty flues can cause chemical attacks to stack mortar (see post 11). Its a possibility that chemical attacks have been gradually taking place in your redundant flues for some time.
Occasionally you can pass a house gable where the back wall of a chimney breast shows a long dark streak - that streak is from unswept/unventilated flues.

Thank you. Your post has brought back some memories of when I was younger and we had a coal fire, my dad would sweep the chimney I’m not sure if it as done when the gas went in and the fireplace was bricked up but there’s definitely no ventilation so I’ll get an air brick put in.

It might be a daft question but the chimney the other side of the house that joins to next door has a gas fire in it. We’ve not used it and I have a feeling it was disconnected. I’ll find out next time the plumber is doing some work but if it’s not being used will I also need an air brick there?
