Semi takes us a day, these big detached houses I allow 2 days, but finish at 3pm knackered by then hahah so usually pop back the following for a few hours to clean up properly and make sure the customer is a happy bunny.
I do not do these full time like you - window cleaning and some pressure washing is my fav. Probably do 1 a week during April to the middle of September then that is it. I go to Spain from the 5th January until the 15th of March, we have a little house in Nerja so roof money pays for the break.
Week off next week, off fishing for a few days on the Wear for the Sea Trout. Then we start a big very mossy awkward one on my return, will pop a few photos up of this one.
