The window cleaning year

When
Busiestspring and summer, and the weeks before Christmas
QuietestJanuary and February, and any run of freezing weather

Customers still want clean windows, but frost stops you working and some customers pause over winter.

How to smooth it out

  • Agree a fixed monthly price with regular customers so they pay the same amount all year, quiet months included
  • Add conservatory roofs, fascias and gutters as extras you can do on drier winter days
  • Move to eight-weekly visits in winter rather than losing the customer
  • Use the slow weeks to walk a new street and fill gaps in the round

The buffer you'd need

Add your running costs to the bills you must cover personally, then hold two to three months of that in a separate account.

Example: a buffer for window cleaning
  1. Running costs: £235 a month (from the example in how to price window cleaning)
  2. Personal bills: £1,400 a month
  3. One month: £1,635

Three months: £4,905

Make the quiet weeks useful

  • Review prices and raise the ones that are too low
  • Ask for reviews and update your photos
  • Leaflet a new street, ready for the busy season
  • Service and replace your kit
  • Do the admin: records, receipts and insurance renewal

Regular customers on an agreed monthly price keep your income steady through the quiet weeks. The general guide has more: surviving the quiet months.
