Equipment You Need
Window washing requires surprisingly little equipment to start, but quality matters more than quantity. Your tools directly affect your speed, safety, and the quality of your results. Cheap equipment breaks, wastes your time, and makes you look unprofessional to potential customers.
Core Cleaning Tools
- Squeegee (12-18 inches): The most important tool you own. A quality squeegee with a replaceable rubber blade gives streak-free results. Most professionals use 12-18 inch widths depending on the job.
- Scraper (4-6 inches): A plastic or metal scraper removes paint, dried caulk, and bird droppings without scratching glass.
- Applicator or microfiber sleeve: Attaches to an extension pole to apply solution to windows before squeegeeing.
- Bucket (5-gallon): You’ll need at least two—one for solution and one for rinsing your tools. Use a separate bucket for cleaning solution.

Extension and Reach Equipment
- Extension poles (6-20 feet): Lightweight aluminum poles let you reach second and third story windows safely from the ground. Most pros have at least one 6-footer and one 12-footer.
- Water-fed pole system (optional): A system that delivers water and cleaning solution through the pole itself. Useful for higher windows but adds cost and complexity starting out.
- Ladder (6-8 feet): For reaching gutters, skylights, and upper story windows when a pole won’t work.

Solution and Supplies
- Window cleaning solution: Buy concentrated solution and mix it with water according to instructions. Cheaper than pre-mixed and lasts longer.
- Squeegee blades (replacements): Buy several extra blades. They dull quickly and replacements are inexpensive compared to the squeegee handle.
- Microfiber cloths and towels: For drying and buffing. Microfiber is better than cotton—it doesn’t leave lint.
- Cleaning rags or chamois: For final buffing and detail work, especially on interior sills.

Safety Equipment
- Safety harness and lanyard: Required if you’re working at heights. Even experienced cleaners use them when climbing ladders or working on steep roofs.
- Non-slip shoes: Wet surfaces are dangerous. Quality work shoes with good grip prevent injuries.
- Gloves: Latex or nitrile gloves protect your hands from solution and cuts. Window edges can be sharp.
- Eye protection: Especially when working below other people or in windy conditions where drips are a risk.

Transportation and Storage
- Equipment bag or caddy: Keeps everything organized in your vehicle and protects tools from damage during transport.
- Vehicle: Any reliable vehicle that fits your equipment works. A truck or van makes loading easier but isn’t required starting out.
- Garage or shed space: You need dry storage for equipment to prevent corrosion and blade damage.
What to Buy First vs Later
Your first purchases should be tools that directly earn you money. Secondary equipment makes you faster and safer but can be added as revenue grows.
- Month 1: Quality squeegee, scraper, applicator, two buckets, window cleaning solution, microfiber cloths, basic 6-foot extension pole, gloves, and rags. Budget roughly $150-300.
- Month 2-3: Additional extension poles (12-footer and 18-footer), replacement squeegee blades, a ladder, and safety equipment.
- Month 4-6: Water-fed pole system if you’re getting enough commercial work that reach is limiting you. Backup equipment so you never lose a day due to a broken tool.
- After 6 months: A truck or dedicated vehicle if you’re not already using one, professional insurance signage, and equipment for specialized services like gutter cleaning or solar panel cleaning.
New vs Used Equipment
Buy new squeegees, blades, and extension poles. These are your primary income-generating tools, and used versions often have invisible damage—bent squeegee edges that don’t seal properly or poles with internal cracks. Quality squeegees cost $25-60 new and last months with blade replacements. A used one at half price that loses you 10% of jobs due to streaks isn’t a savings.
Used equipment is reasonable for ladders, buckets, and vehicles. A used 6-foot ladder works fine. Used vehicles save money if they’re reliable—window washing is hard on vehicles due to water and cleaning chemicals, so mechanical reliability matters more than appearance. Avoid buying used extension poles unless you can inspect them carefully; a bent pole creates leverage problems and increases safety risks.
Never buy used or cheap safety equipment. A $40 fall harness isn’t worth the risk. If you’re climbing ladders regularly, your harness and rope need to be new and rated for your weight and situation.
