I am trying to vent chimney buy feel no air going through.

[Gary111]

Hi, I am trying to vent a brocked up chimney breast, I have drilled a few holes but cant feel any air going up.

It felt like I went through 2 brick thicknesses.
Any ideas please?

Is it capped or open at the top??

 

[Gary111]

Hi, it's capped as far as I know, but the others in the building were capped but still ventilated.

You say: Your fireplace opening to the flue has been blocked, and you've drilled some holes.
Flues need through venting eg an inlet vent at the bottom of the flue, and an opening or custom vent at the top of the flue.

You also mention "capping" the flues in your property.
Are you saying a chimney stack or chimney stack pots have been capped?
Why not post pics showing where you drilled into the chimney breast, and where the flues have been capped?
Pics of the other fireplaces would also help.

Hi, Heres a pic of the top of the chimneys, hard to see as it's a 3 storey building, there is a fireplace on each floor

If its capped at the top you won't get thru ventilation.

Your pic shows a clay venting terminal - typically used for through venting a redundant flue where there is an opening or a vent at the bottom fireplace.
The pic also shows three air bricks in the stack brickwork suggesting that the air bricks are venting other redundant flues.
Your pic does not show how any of the flues have been capped - if they are indeed capped?

If you posted (as previously suggested) pics of all your fireplaces it would help?
A somehow obtained pic of the top of the stack - the flaunching - would also help?

Have you experienced leaks or staining on that gable wall and chimney breasts?

are all the fireplaces disused ?

The pic, of course, shows a clay venting terminal - the vertical slots indicate, to those who have experience and knowledge, that its an air vent for redundant flues.
Its not, and shouldn't be used as, a gas terminal.

Thanks for your answers, I have only just had time to post the picture of the fireplace.
I have drilled a few holes behind the vent cover.

The fireplaces are all disused.
I don't get much damp on the chimney breast, but want to generally improve ventilation in that room, the surveyor recommended that a vent be fitted.
Thanks

Gary111,
The pic shows a chimney breast with no signs of chemical staining. You could stitch drill or use a masonry hole saw to open up behind your plastic vent.
Pics of all the c/breasts were asked for - you might not see much but I might, simply due to experience.
Thats why I asked.
Best practice is for all chimney flues to be smoke tested and swept before any fireplace blocking up - and the condition of the stack flaunching and terminals determined.

Thanks, what I am.thinking is that if I can't feel any draw from a few holes drilled it's probably not worth drilling any more.

This flat is above the ground floor one, which does have bubbling paint.

paint on chimneybreast keeps bubbling and peeling

The paint on this side of the chimney breast keeps bubbling up. What can I do to remedy that please ? Ground floor flat in house built maybe 1900 Thanks

A bit late in the day, mate - you would have saved a bit of time and energy if you had mentioned your post Jan 2022 earlier.
I explained & suggested in that post what you should do.
Still dont see the pics requested?
