I have had deep cleaning help in the past, especially during difficult pregnancies. A crew came once a week for a few hours and deep cleaned everything, costing $80 for a four bedroom house. I tried to save money in other areas to cover the cost, but since it was always short-term I never specifically budgeted for it.
Overall, I have solved the problem of dealing with the house, errands, laundry, cooking, schooling, and just having 4 babies in 6 years, by always having another family member living with us. I'm the oldest of 7 and the first to marry in the family. I've had a couple of my younger siblings, fresh out of college and in need of a place to live, come live with us for a few years at a time. In exchange for room and board, they help with cleaning and babysitting. They get a few years to get on their feet financially while I get desperately needed help for free!
