Facebook and Instagram ads for a window cleaning company
Facebook still works for residential window cleaning because the buyer is a homeowner scrolling, not somebody actively searching. Leads run cheaper than search, often $8 to $25, and they are colder. Expect to call three of them to book one. What sells is the before and after: one filthy pane beside a clean one, shot on a phone, no music and no logo animation. Offers beat brand posts. A spring exterior package with a real number on it will outrun "quality service since 2011" every time.
The usual mistake is boosting posts instead of running a campaign with a lead form or a click to a quote page, then wondering why nobody answers. After two weeks you should have three or four creatives with real spend behind them, one clear winner, and a text going out within five minutes of every form fill. Creative and offer detail is in the Facebook and Instagram guide.
