🔬 AI-Generated Research from r/WindowCleaning and r/SweatyStartup Window cleaning is quietly one of the best low-capital service businesses you can start. Here's a breakdown from real operators sharing their numbers on Reddit: **The $15K-in-3-Months Story:** A window cleaner on r/WindowCleaning shared their 3-month update: just over $15K in recurring revenue, with 25-40% month-over-month growth. They bought a van and water-fed pole (WFP) system and were hitting $1,500 weekends. Another operator in Florida did $3,940 in their first three weeks. Yet another hit $10.69K in their very first month. **Startup Cost Breakdown (Real Numbers from Reddit):** - Basic equipment (squeegees, sponges, soap, bucket, ladder): A few hundred dollars - Insurance (Hiscox minimum coverage): ~$40/month - You can literally start with $0 by booking customers first, buying gear on a credit card, and paying it off from your first jobs **The Lead Generation Playbook That Actually Works:** 1. Google Local Service Ads (LSA) — Get Google Guaranteed ASAP. This is the #1 lead source for most operators. 2. Thumbtack — One operator reported a 90%+ win rate on Thumbtack leads 3. Facebook Ads — Hit or miss, but works well with before/after video content 4. Door knocking and cold outreach to real estate agents and property managers 5. Cold email facilities managers for commercial contracts **Business Setup Tips:** - You don't need an LLC to start — sole proprietorship works, revenue filed through normal tax return - 100% need insurance though (some states require it legally) - Use Puzzle.io for free accounting (free up to $5K monthly expenses) - Process payments via Venmo/Zelle at first, move to Stripe as you grow - A simple one-page website via Carrd.co is enough to start **Key Insight:** Window cleaning has natural upsell paths into pressure washing, gutter cleaning, and holiday light installation. The combination of low startup cost + high hourly rate ($50-$100/hr effective) + recurring revenue (customers need windows cleaned 2-4x per year) makes this one of the strongest service-business entry points. **The Confidence Factor:** Multiple operators noted the hardest part is getting your first customer. Once you clean a few sets of windows and see how straightforward it is, confidence explodes and growth follows naturally.
