Domestic customers are done 4 or 8 weekly if we get behind due to bad weather or holidays that’s just a fact of life it's window cleaning it’s not going to kill them if the windows are dirty for a bit longer , we will not book jobs in for specific times to many variables but will do jobs on very large properties by booking a time and date but only jobs that run into hundreds of pounds per clean . Commercial is different we do do jobs on specific dates ,especially hotels, nursing homes , care homes , schools, etc but again theses are large jobs and very profitable,
