hi there
we never ever subbed out the window cleaning, because of the costing involved, i was quoted £1.50 per pane per side, and at that pint makes it far to expensive.
the bathrooms and the kitchens are going to take the time.
the airing cupboard, make sure that you wipe down all the pipework, valves etc.
the door architrave, especially the tp architrave, alng with the top of the doors.
the door hinges, may well have paint on them.
the top of the kitchen units need to be cleaned, along with the underside of the wall units, these will be dirty after the tiling.
light switches and sockets require cleaning, and paint removing, the top of the boiler will need wiping. the tps of the skirtings will be very dusty.
pull out the drawers completely in the kitchen, you'll be amazed at the amount f debris in the carcass of the drawer unit.
regards
martin
