How to Start a Window Cleaning Business: Gear, Pricing, and First Customers

Window cleaning is one of the lowest-cost, fastest-to-revenue home service businesses you can start. Startup costs run $500-$2,500, the skill floor is learnable in weeks, and recurring commercial work builds a predictable base most trades would envy. Here is what it actually takes to go from zero to a real business.

Startup Costs and Essential Gear

You can start residential window cleaning with less than $1,000 in equipment:

• Squeegees and channels in 2-3 sizes, plus spare rubber: $60-$120
• T-bars, sleeves, and scrubbers: $40-$80
• Towels, scrapers, applicators, holsters, bucket: $80-$150
• Extension pole (up to 24-30 ft reach): $80-$200
• Ladder (fiberglass, appropriate rating) and stabilizer: $250-$500

The one upgrade worth considering early is a water-fed pole system ($1,200-$3,500 with a pure-water setup). It lets you clean exterior glass up to 3-4 stories from the ground, faster and safer than ladder work, and it is the standard for storefront routes and two-story residential exteriors.

Beyond gear: a reliable vehicle, general liability insurance ($400-$900/year, non-negotiable, commercial clients will ask for the certificate), and whatever business registration your state requires. Total realistic launch budget: $1,500-$4,000 including insurance and basic marketing.

Pricing: Per Pane Beats Guessing

Window cleaners price per pane, per window, or per job. Per-pane is the most defensible because it scales with actual work:

• Standard pane, exterior only: $4-$8
• Interior + exterior: $8-$14 per pane
• Screens: $2-$5 each; tracks and sills: $1-$3 per window
• French panes, storm windows, hard-water stains, post-construction: priced up or quoted separately, these can double the time

Set a job minimum of $150-$250 for residential; below that, the drive and setup eat the margin. A typical 20-window home at interior/exterior rates lands between $250 and $450 depending on market and access.

For storefronts, price low per visit but win the frequency: a $30-$60 storefront cleaned biweekly is $780-$1,560 a year from one stop, and storefront routes cluster tightly, so drive time per dollar is minimal.

Landing Your First 20 Customers

The first customers come from proximity and proof, not ads:

1. Storefront walking route. Pick a commercial strip, clean one anchor storefront cheap or free, then walk the block with a simple offer: "I do the shop two doors down every other week; first clean is half price." Storefront owners buy from people standing in front of them.
2. Door hangers around every completed house job, mentioning the neighbor's address. Clean windows are visible from the street; the timing sells itself.
3. Google Business Profile from day one. Photos of your work (glass is photogenic), service list, and a review request texted after every job. Ten reviews in your first two months changes your inbound completely.
4. Realtors and property managers. Pre-listing cleans and move-out cleans are steady, unglamorous, and referral-rich.

Build for Recurrence From Day One

The difference between a window cleaning job and a window cleaning business is repeat frequency. Every completed job should end with a scheduled next visit: quarterly or biannual for homes, biweekly or monthly for storefronts. Offer 10-15% off the one-time rate for customers on a schedule; the discount costs less than finding a replacement customer.

This is also where paper systems collapse fastest. Fifty recurring customers on mixed frequencies is beyond memory and spreadsheets: who is due, who canceled once and never got rebooked, which storefront pays net-30. Field service software like Roooster handles it: recurring jobs generate themselves onto the schedule, invoices go out automatically, and every customer's history and frequency lives in one record. Start on real systems while you are small and the growth never outruns your operations.

The Realistic First-Year Picture

A solo operator charging fair rates, working a growing route 4-5 days a week, typically reaches $4,000-$8,000/month in revenue by the end of year one, with commercial route work smoothing the seasonal dips. The ceiling after that is crew-based: two 2-person crews on dense routes is a $300,000+/year operation. It all starts with a squeegee, insurance, and the discipline to ask every single customer for the next booking.
