Neighbours Bathroom Exhaust in Chimney Flue

[rideforever]

Got a victorian maisonette and the gff has a bathroom exhaust that goes into the chimney and is causing damp patches. His pipe runs from his bathroom fan about 1 m under my living room floor into the chimney.
Question is if we can agree that he needs to get a proper pipe put in, where does it go?
He might press me to run a pipe another 3m under my living room floor? Noisewise, cutting through 100 year old floors wise and running a plastic pipe in front of the fire place wise ... I don't think that would be good for us up here. On the lease I own the floor, I guess that's normal.
Or is it his responsibility to put it on his side of the ceiling which would be the top of his bedroom wall or out the back onto the flat roof?
Cheers for any advice.

Could the pipe be extended to vent out of the top of the chimney?

Yes he should have chimney liner or trunking the length of the chimney and yes he can't encroach on your property to do it. Depending on the type of fan he is using it may not powerful enough to blow air up and out the chimney and that would contribute to damp.

I am sure it would be easy to do that, however it's 8m from inlet to chimney pot vertical and the result will be a puddle at the bottom I suppose. At the moment its 8m of brick that's taking the condensation.

How do you know so much about his vent pipe without lifting your floor?

What makes you believe that the extractor is causing the problem? If it's an old (fossil fuel) chimney then it could be several reasons that stains are showing.

There is a stain 3 m above the exhaust into the chimney point, which is the ceiling of the 1st floor. With 2nd floor and loft above it.
No services on that side.
Also patches wax and wane even when it's 30C outside.
