Hi there, 

in both our bathrooms there are drafts coming in from where the sink pipe comes through tiles… what is the best way to stop this….

 

we moved in last winter and need fixed before it gets cold…

 

thank you

Is the draught coming in from outside or from inside pipe boxing? Do the pipes run to outside or into an internal soil pipe in a box? Is it a cavity wall house or is it dot and dabbed? 
 

 

Can you post a picture that will clarify the question above.  Also more details on the house, age, type of construction etc.

 

You can seal any gap around the pipe with something like solicone sealant but that may just shift the draught to somewhere else if you are not fixing the root problem of how the fraught is getting in.
