Cleaned a customer's battersea penthouse suite (office) today next to the London Heliport, probably the windiest I've ever worked in.
Had to press myself flat against the glass several times, grasping the window frame. Wrap around roof terrace was thankfully big enough but feels awkward being 7 floors up. Water almost flying out of the bucket!
Wfp might be an option, but it's additional hassle getting a trolley + barrels up there. Suds flying everywhere so had to do some inventive fanning, but is nice and clean again.
Usually don't get to go up to London very often, so it's one of those special jobs that I do twice a year. Nice seeing the helicopters coming in to land at eye level. One of them with fixed skid type gear had to taxi/fly in sideways through the entrance of the heliport, it was so windy. Great skill.
