Your 10 Biggest Questions Answered (Plain & Simple)
You clean interior and exterior windows for homes and small businesses.
1. Do I need a certificate?
No. You need proper technique and attention to detail.
Can you leave windows streak-free and sparkling? That’s your skill.
What to do instead:
- Practice on every window in your own home.
- Develop efficient cleaning methods.
- Take before/after photos showing reflection clarity.
2. What’s the minimum I need to spend?
$100-$200 for professional supplies.
- Squeegee kit: Different sizes, scrubber, handle ($30-50)
- Cleaning solution: Professional concentrate or make your own
- Ladders: Extension ladder for exteriors (borrow initially if possible)
- Safety equipment: Harness for high work (crucial for 2nd story+)
- Bucket, cloths, towels
Total: $150-300 to start safely.
3. How do I describe what I do?
DON’T say: “I clean windows.” (Too basic)
DO say: “I provide professional window cleaning services for homes and businesses, leaving every window streak-free and sparkling.”
Build trust:
- “Insured and safety-trained” (get insurance once you can)
- “Interior and exterior cleaning”
- “Residential and commercial”
- “One-time or recurring service”
4. Where do I find my VERY first client?
Start with single-story homes and small businesses.
- Your neighborhood (easy access, lower risk)
- Local small businesses (storefronts, offices)
- Real estate agents (preparing homes for showing)
- Property managers (apartment complexes)
Door-to-door approach: “Hi, I’m offering window cleaning services in the neighborhood this week. I’m doing special pricing for first-time clients at $X. Would you be interested in a free quote?”
5. How much do I charge?
Per window or flat rate: $150-$400+ per average home.
Common pricing methods:
- Per pane: $5-10 per pane (each separate glass section)
- Per window: $10-20 per window (entire unit, inside and out)
- Flat rate: Average 3-bedroom home: $200-350
Example: 20 window home at $10/window = $200
Commercial: Storefront: $50-150 depending on size

6. What does cleaning windows look like? Step-by-step
Project: “Standard Home Window Cleaning” (3-4 hours)
For each window:
- Exterior:
- Apply cleaning solution with scrubber
- Starting at top, pull squeegee down in straight stroke
- Wipe blade between strokes
- Dry edges with cloth
- Interior:
- Remove any window treatments if possible
- Same technique as exterior
- Clean window tracks and sills
- Final check:
- Inspect for streaks from inside looking out
- Touch up as needed
- Ensure tracks are dry to prevent mildew
Professional secret: Use distilled water in final rinse to prevent mineral streaks.
7. How do I handle payment safely?
Payment upon completion, before you leave.
Cash, check, or digital payment. For commercial clients: invoice with net-15 terms once established.
Insurance: Get liability insurance before doing second-story work ($50-100/month).
8. What’s the #1 beginner mistake?
Working in direct sunlight or on hot windows.
Solution evaporates too quickly, leaving streaks. Work early morning, late afternoon, or overcast days. Work in shade when possible.
Bad timing = rework = lost profit.
9. How do I know if I’m good enough?
You’re good enough if:
- Your windows are completely streak-free from all angles.
- You can clean efficiently (10-15 minutes per average window).
- You leave no water marks or drips on frames/sills.
Test: Clean a window, then look at it from different angles with sunlight hitting it. Any streaks? If no, you’re ready.
10. What’s the next step?
Offer recurring services and complementary add-ons.
After one-time cleans, convert to: monthly, quarterly, or bi-annual maintenance plans.
Add services: screen cleaning, track cleaning, gutter cleaning, pressure washing.
