I don’t think that sound unreasonable when I think about how long it takes me to clean my internal windows and I’m pretty fit and agile. They get a wash with soapy water and then a squirt of window cleaner and a good polish.
I pay my outdoor window cleaner £20 for a house that has a similar number of windows to yours when I include a large garden room. He uses a pole-driven, filtered-water system. It takes him about 20 minutes to do the outside. He cleans two neighbours' similar houses so he’s charging say £60 an hour.
Cleaning indoor windows is a different kind of task. You don’t want to be slopping water over floors and carpets for a start. Plus there is wallpaper, window dressings and furniture to take into account and negotiate.
When I clean my indoor windows I tend to do two rooms at a time e.g. two bedrooms at a time, sitting room and hallway, kitchen and utility room. dining room which has large french windows and garden room off; two bathrooms. Say an hour for each pair, taking into account removing and replacing window dressings.
It can take me a good two hours to clean the inside windows of my garden room including moving all the plants around. It’s south facing so it can take a lot of effort to get them smear free in the sunlight. Paintwork gets a wash down too. It can get humid in there so I have to keep an eye out for mould forming in the gap between glass and frame which adds to the cleaning task if I have to give it a scrub with an old toothbrush.
If you allow an hour for two rooms at only £20 an hour, the cost soon mounts up.
Why do hospitals, most of whom have large catchment areas, make accessing them so difficult?
