How to Start: Step-by-Step

1

Choose Your Market Focus

Residential offers higher per-window rates and flexible scheduling. Commercial provides larger contracts and predictable recurring revenue. Storefronts are ideal for beginners—quick jobs, frequent service, easy to acquire. Most successful operators combine all three for diversified income.

2

Learn Proper Technique

Master traditional squeegee technique before investing in equipment. Practice on your own windows. Key skills: proper solution mix, squeegee angle, no-drip finishing, and streak-free results. YouTube tutorials plus practice—or work briefly for an established company to learn.

3

Register Your Business

Form an LLC for liability protection ($50-$500). Get your EIN from the IRS (free). Most areas don't require special window cleaning licenses, but check local requirements. Register for state sales tax if applicable.

4

Get Insurance

General liability insurance ($500-$2,000/year) is essential—you're working at heights near expensive glass. Many commercial clients require $1M-$2M coverage. Add workers' comp when hiring employees. Insurance is non-negotiable for professional operations.

5

Purchase Equipment

Start basic: professional squeegees ($15-$40 each), scrubbers, bucket-on-a-belt, quality ladders. Total: $500-$1,500. Add extension poles for 2-3 story residential. Water fed pole systems ($2,000-$5,000) optional but increase efficiency for high work.

6

Set Your Pricing

Residential: $4-$15 per window or $150-$400 per home. Commercial storefronts: $2-$5 per window, weekly/bi-weekly contracts. High-rise: specialized pricing based on difficulty. Research local rates but focus on value, not being cheapest.

7

Build Your Client Base

Start with storefront route—walk into businesses, offer a free demo window. Use Google Business Profile for residential leads. Door hangers in upscale neighborhoods. Referral incentives. Property managers for commercial buildings. Consistent quality builds word-of-mouth.

8

Scale Strategically

Build a storefront route for steady base income. Add residential for higher margins. Pursue commercial contracts once established. Consider adding pressure washing or gutter cleaning as complementary services. Hire when you're turning away work.
