Bigotry at home to cleaner, sadly (11)
I believe the answer is:
intolerance
'bigotry' is the definition.
(I've seen this before)
'home to cleaner sadly' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'sadly' indicates an anagram.
'cleaner' with letters rearranged gives 'lerance'.
'in'+'to'+'lerance'='INTOLERANCE'
'at' is the link.
(Other definitions for intolerance that I've seen before include "D W Griffith film" , "Lack of acceptance of others' views" , "Inability to endure (something)" , "antipathy to different views" , "Unreasonable refusal to accept" .)
