Start a window-cleaning side hustle — one of the lowest-cost, highest-margin service businesses there is, and you can start it this weekend with a bucket and a squeegee.

Window cleaning is a near-pure-labor trade: the materials are cheap (soap, a squeegee, scrim, DI water), the demand is recurring (glass gets dirty on a predictable cycle), and a competent solo operator earning a strong per-hour rate needs only a modest route to make it worthwhile. Most homeowners want clean windows and have no interest in balancing on a ladder to get them — which is the entire opening. This is a done-for-you operating system for starting that gig solo, part-time, and self-funded — no LLC required, taxes as simple as Schedule C — and growing it as far as you want.

What's inside

The craft that separates a pro from a streaky amateur — traditional squeegee and water-fed pole. The squeegee technique and detailing that leaves glass streak-free (the amateur signature is streaks and missed edges), plus the water-fed-pole method for reaching second-story and hard-access glass safely from the ground, and the add-ons that lift the ticket — screens, tracks and sills, and hard-water/mineral-stain restoration. The safety and ladder discipline is built in.

An editable financial model built for a part-time, self-funded start — no loan, no lender. A ~$1,500 self-funded startup (squeegees, water-fed pole, DI setup, ladders, insurance), per-pane pricing around $4–8, an average residential job near $250, and a gross margin around 85% before your own pay — because window cleaning is a genuinely low-materials service where your time is a draw, not a cost. Change the pricing units, the job mix, or the route and the projection re-flows. Taxes are Schedule C + self-employment tax, with a clear "when to form an LLC" trigger for later.

The route-density and recurring-revenue engine that turns one-off jobs into a book. Neighborhood-batch scheduling (clean one house, quote the block), fast photo-based quoting, before/after proof and reviews, and recurring maintenance plans (quarterly or biannual) that turn a one-time clean into predictable repeat revenue — plus the realtor and property-manager relationships that add weekday work.

Who it's for

Built for one person starting a window-cleaning route on the side — distinct from pressure-washing or handyman work; this is a self-funded, part-time, grow-it-as-you-want service you can start this weekend. Instant download, yours to edit, single-buyer license.
