Window Cleaning as a Service Business

Why this matters

Window cleaning is a recurring-revenue specialty with low startup cost and high customer retention. Residential customers want windows cleaned 1 - 4x per year; commercial customers monthly or quarterly. Solo operator can generate a solid full-time income; multi-crew operations scale into a much larger multiple of that. Margins 50 - 70%. The skill barrier is moderate - anyone can wash a window badly; few do it consistently well. The pro who masters technique builds a loyal customer base + premium pricing.

Technique (interior + exterior glass)

Standard squeegee method:

1. Wet the glass with soapy water using T-bar
2. Position squeegee at top corner, blade angled
3. Pull squeegee across glass in a steady stroke
4. Wipe blade on lint-free cloth between strokes
5. Final detail: corners + edges with dry cloth
6. Inspect for streaks; touch up

Common technique mistakes:

• Streaks from dirty squeegee blade
• Soap residue at edges
• Not enough water (squeegee skips)
• Pulling too fast OR uneven pressure
• Skipping spots in corners

Water-fed pole technique:

1. Brush + pure water rinse the window
2. Pure water has no minerals → dries spotless
3. No squeegee needed
4. Works on heights up to 60+ ft from ground
5. Different finish than squeegee (some customers prefer one or other)

Commercial pricing

Per-pane:

• Standard: priced per pane, scaled up for height/lift access and premium multi-location accounts

Recurring contracts: storefront weekly, office-building monthly, high-rise quarterly - each priced well above the per-visit residential rate to reflect volume + access complexity.

Seasonal patterns

Spring peak: customers want clean windows for season (April - June biggest).

Summer steady: ongoing demand.

Fall busy: pre-winter cleaning (September - November).

Winter slow (cold climates): mostly commercial work indoors OR pivot to other services (gutter cleaning, holiday lighting).

Customer retention

• Customer auto-scheduled for next visit
• 3 - 6 month intervals typical

• Follow-up call OR text next day

Common business mistakes

Underpricing: a whole-house quote priced too low barely covers cost.

Skipping screens / sills: customer notices + complaints.

Bad weather scheduling: cleaning in rain = streaks; reschedule.

Insufficient insurance: ladder fall claim destroys business.

No recurring system: cleaning customers once + losing track.

Wrong technique for surface: squeegee streaks won't satisfy premium customer.

Equipment cuts corners: cheap squeegees streak; tarnishes reputation.

Safety + liability

Ladder safety:

• 4:1 ratio (1 ft out for every 4 ft up)
• 3-point contact rule
• Stabilizers + standoffs
• Never overreach
• Customer's ladder NOT recommended

Falls + height:
