Chris I would say £100 for a one off price that bird crap is going to need some soaking and scrubbing

.
Plus those panels look in a right state so a good soak in tfr or ubik should bring them up a treat.
Morning works mate

.
Monthly I would do it for £40- £50 not many windows and the pvc panels wont need rinsing so a quick wash (unless bird crap on them!!!)
Bi monthly £60 same as above mate.




Cheers
Stuart
