Yeah Commercial interiors are sometimes lucrative
I actually admit to doing the odd one
What i really meant was, when a householder asks for trad on exterior i flatly refuse
I used a squeegee for at least 10 years so I'm capable without being top!!!
I gave an inside clean on an office i do the exterior of, to my youngest son, £100 for just over 2 hrs is ok, and he's not lightning like me, he does a good methodical job
