GB still got a lot to learn mate!!

i would of charged a min of £60 for the roof and id of cleaned the windows/outside gutters on the conservatory as part of the service.
it would takes about 90 mins from pulling up to driving away.
this is what i would of done.
ladders and stand off(so there not resting on the gutters)climb up and spray a strong mix of tfr/warm water with pressure sprayer(already mixed before i set off for work) 2 panels at a time.
while thats soaks in.get the wfp out(with stiff vikan sill on the end!)spray another 2 panels and wfp the first 2 while the other 2 soak in etc,etc until there all scrubbed and rinsed well.
then concentrate on the ends of the roof and outside gutters with just the wfp.finally finish with a good scrub and rinse of the conny windows!(job done!!).
time taken about 90 mins.
