Why Window Cleaning Is One of the Best Service Businesses to Start
Window cleaning has some of the most favorable economics of any field service business: low startup costs, no licensing in most jurisdictions, high profit margins, and strong recurring demand from both residential and commercial customers. An experienced window cleaner can generate $500–$1,200 in daily revenue with equipment that fits in a car trunk.
This guide covers what you actually need to get started (under $500), how to price your first jobs competitively, and how to find your first 10 customers.

Pricing Your First 10 Jobs
For residential window cleaning, pricing is typically per-pane or by home size. A practical approach for new operators:
- Inside and outside residential: $4–$7 per pane (simple) or $150–$350 for a typical single-family home
- Outside only: $2.50–$4 per pane or $80–$200 for the exterior
- Storefront (commercial): Monthly recurring, priced per visit — $50–$250+ depending on window count
Price your first 10 jobs at a slight discount ($20–$30 off) in exchange for a review. Your Google rating will pay dividends in revenue far exceeding the discount. See our guide on getting 5-star reviews.
Finding Your First 10 Customers
The fastest path to first customers:
- Your existing network first: Tell every contact you have. Offer friends and family a demonstration clean at cost — this generates reviews and word of mouth.
- Nextdoor and community Facebook groups: Post a profile intro and a limited-time offer for first customers in your area.
- Go to the storefronts: Walk the commercial strip in your area. Ask to speak to the owner or manager. Offer a free sample on one window — most will convert to a monthly account if the work is quality.
- Google Business Profile: Set up on day one. It's free and will start generating calls within weeks if you get reviews early.
