Market Opportunity in Wisconsin
Wisconsin offers a solid market for window cleaning, driven by its mix of older homes with many windows (especially in Milwaukee, Madison, and the Fox Valley) and a growing commercial sector. The state's distinct seasons create a peak season from May through October, when homeowners and businesses want their windows cleaned after winter grime. Demand is consistent in suburban areas where homeowners value curb appeal and property maintenance. The market is somewhat underserved in mid-sized cities like Appleton, Eau Claire, and La Crosse, where national franchises have less penetration. However, the short peak season means you must maximize revenue during those months; winter work (interior-only, holiday lights, or snow removal) can supplement income. Overall, Wisconsin is a good market because of its dense suburban belt around Milwaukee and Madison, and the lack of a state-specific license barrier.
State Licensing & Legal Requirements
- Business Registration: Register your business name with the Wisconsin Department of Financial Institutions (DFI) (for LLC or corporation) or file a Trade Name (DBA) with your county clerk's office if operating as a sole proprietorship.
- Seller's Permit: Register with the Wisconsin Department of Revenue (DOR) to collect and remit sales tax (5% state rate + local county rates, e.g., 0.5% in Milwaukee County). Window cleaning is a taxable service in Wisconsin.
- Local Business License: Most cities (e.g., Milwaukee, Madison, Green Bay) require a general business license or home occupation permit. Check with your city clerk’s office.
- Insurance: General liability insurance ($1 million per occurrence) is essential. Workers' compensation insurance is required if you have any employees (even one part-time). No state bond is required for window cleaning in Wisconsin.
- No Professional License: Wisconsin does not have a specific license for window cleaners. No contractor registration is needed unless you also offer construction-related services.
Startup Costs
| Item | Low-End Cost | High-End Cost |
|---|---|---|
| Basic window cleaning equipment (squeegees, buckets, scrapers, extension poles, microfiber cloths) | $200 | $500 |
| Water-fed pole system (optional but recommended for taller residential or commercial) | $800 | $2,500 |
| Ladder (24 ft. extension) | $150 | $400 |
| Vehicle (use your personal car; no dedicated van needed initially) | $0 | $0 (if you already own) |
| Liability insurance (first-year premium for $1M coverage) | $400 | $1,200 |
| Workers' comp (if you hire someone; typical start at ~$500-$1,000 depending on payroll) | $500 | $1,500 |
| Business registration and local license fees | $150 | $500 |
| Sales tax setup (DOR – free to register) | $0 | $0 |
| Initial marketing (door hangers, flyers, GBP setup, Google Ads deposit) | $200 | $1,000 |
| Total estimated startup range | $2,400 | $8,600 |
Expected realistic startup for a solo operator: $2,500–$3,500 if you already own a car and ladder.
Revenue Potential in Wisconsin
Average residential job ticket in Wisconsin: $175–$350 (single-family home, standard 15–25 windows). Commercial jobs (storefronts, offices) average $250–$600 per visit. Larger homes or multi-story buildings can reach $500–$1,000.
- $5,000/month: Requires about 20–25 average residential jobs. Realistic in peak season (May–Oct) by working 4–5 days per week with consistent lead flow.
- $10,000/month: Requires 40+ residential jobs or a mix of larger commercial contracts (e.g., 5–8 medium commercial accounts at ~$1,200 each). Many Wisconsin window cleaners achieve this by May–June with recurring services and referral networks.
Milwaukee and Madison markets support higher rates ($200–$400 per home) due to higher cost of living and more affluent suburbs (e.g., Brookfield, Mequon, Shorewood). Smaller cities (Oshkosh, Wausau) are slightly lower, $150–$250 per home.
Your First 30 Days
- Day 1–3: Register your business (choose LLC for liability protection), get your EIN from IRS, and set up a business bank account. Register with Wisconsin DOR for sales tax.
- Day 4–7: Purchase insurance (get a quote from an independent agent who knows window cleaning – try Hartford or local agencies). Buy equipment: at minimum, a quality 18″ squeegee, bucket, Unger ErgoTec handle, a 24-foot ladder, and microfiber cloths. Skip the water-fed pole for now unless you target two-story homes.
- Day 8–10: Create your Google Business Profile (GBP) – pick a category, add photos of your equipment, and set a service area within 20 miles of your home base. Create a simple website (or use a GBP landing link).
- Day 11–14: Print 500 door hangers (Vistaprint or local printer). Target neighborhoods with older homes (pre-1960s) and larger windows – drive around and hang on doorknobs. Offer a $30 first-time discount.
- Day 15–20: Join two local community Facebook groups (e.g., “Brookfield Neighbors” or “Madison Moms”). Offer a special for group members. Also, post an ad on Nextdoor – it works well in Wisconsin suburbs.
- Day 21–25: Knock on 5–10 doors daily in a chosen neighborhood (early evening). Introduce yourself, leave a card. Ask neighbors for referrals. Do your first free (or heavily discounted) job for a friend or family member to get a before-and-after photo.
- Day 26–30: Send thank-you texts to everyone you’ve contacted. Ask the first few paying customers to leave a review on GBP. You should have at least 3–5 jobs booked by end of month.
