Another blocking up chimneys thread.

[ScottishGasMan]

Hey all,

planning more work on my house at the minute, 1920 solid stone semi detached bungalow/cottage sort

on the main outside wall of the house there is a chimney, feeding two old openings in seperate rooms that have been boarded up along time ago.

both have small vents on them, one of which is in a bathroom half way up a wall (belive this used to be a bedroom a long time back) problem is i want to fit selotex and then tile over in that room

everyone says that you shouldnt block chimneys so as to prevent damp probs.

Would it then be acceptable to drill a few 15/20mm holes through the chimney to outside and fit a vent on outside wall so I can block over internally with out fear of damp issues?

Yes, the chimney can be vented either internally or externally, the essential thing here is to ventilate the stack...pinenot

P.S. just make sure the external vent is weather proofed

Thanks mate, that makes like a hundred times easyer. Just need to find some external vents now that dont look silly on a sandstone wall now


thanks again

Partial venting of a chimney is a bad idea. It encourages condensation.

I must admit, I had assumed the chimney to be open or capped & vented at the top already, and a external vent at or about knee level say, to provide a positive air flow.
Well spotted joe90 ...pinenot

Chimneys Open at the moment, will be trying to get elephants foot terminal or similar on soon, and vent dtilled to outside from chimney so I can seal up inside with celotex and tile backer
