Part 1 - How to start a Window Washing business - Background

A window washing business cleans residential, commercial, and institutional windows on a retained or per-assignment basis. As the owner of a window washing business, you’ll be responsible for recruiting clients and washing the windows—on a one-time or regularly contracted basis—of residences, apartment complexes, storefronts, colleges and universities, funeral homes, car dealerships, and other properties—potentially just about any structure that contains windows. You can start your business alone or buy into a franchise operation for its experience and support. Some window washing businesses specialize in high rise window cleaning, but this involves a much larger capital outlay for equipment, training, marketing, and insurance.

Our guide is in 3 parts:

What are the costs involved in opening a window washing business?

Window washing, even at a modest entry level, is not inexpensive. You have to pay for at least one transport vehicle, basic equipment, cleaning supplies and liability insurance for yourself even if you’re your sole employee at first and you’re only taking on jobs on one- or two-story structures. Here’s how your costs break down:

Transport vehicle with signage—$7,000 per vehicle-plus. This would be the cost of a used van in reasonable condition and wrap-around signage. This type of vehicle is important not only to get one or more workers to the job, but also for transporting heavy and cumbersome equipment and supplies.

**Gasoline and maintenance—**At least $5,000 per year. This actual expense will depend on how many vehicles you own or operate, the age and condition of the vehicles, your area of operation, number of clients, current price of fuel, and other factors. As you can imagine, this figure could be much larger in your case.

Liability insurance and bonding—$350 to $1,000 per employee. This is critical in your line of work since a worker could fall off a ladder and be slightly injured even when working on a single-story structure. Visit this insurer’s website to learn more.

**Tools and gear—**More than $750. This would be the cost of a modest extension ladder, buckets, squeegees, water hoses and water-fed poles for low rise work. As you might imagine, your expenses escalate the higher your assignments take you or your workers. In that case, add harnesses and hard hats to the basic inventory. Cranes and scaffolding can be rented as needed. Visit this window washing products website for an idea of the gear you might need now or in the future, and the costs involved.

Cleaning supplies—$200 (est.) You can start with only enough cleaning supplies to handle jobs already contracted. Keeping your inventory low prevents cash flow and storage hassles.

**Office/storage space—**Zero to $12,00 per year or more. If operating on a budget, you could conduct your business from home and keep all of your equipment and cleaning supplies in your work van. As your business picks up you might feel the need to rent adequate space for workers to meet and your gear to be stored.

Sales and marketing—$2,500 or more. This is to cover logo development, signage, web development, initial advertising, and related expenses.

**Employee costs—**Figure at least $25,000 per employee per year, even if that employee is you. If you’re starting alone and have saved enough to support yourself before you start generating adequate income, this figure might be lower. On the other hand, it could be higher depending on minimum wage or cost of living in your area.

Business licenses and related licensing—$300 or more, depending on location.

**Association membership—**Annual dues of $250 or more. Membership in the International Window Cleaning Association will earn you discounts on products you’ll need, training and support, and an opportunity to earn certification in the various areas of specialization in window cleaning. This could be a critical selling point to customers concerned about safety issues.

What are the ongoing expenses for a window washing business?

Your largest ongoing expenses will be the cleaning supplies you use, fleet fuel, maintenance costs, and employees. Therefore, these costs will rise and fall depending on your current volume of business.

Who is the target market?

Anyone within your area of operations who owns or manages real estate with windows is a potential client, but those who’d like to maintain the appearance of their properties are your primary customers. This can include homeowners as well as commercial and institutional property owners. The demographic makeup of your geographic location will help define your primary client base.

How does a window washing business make money?

You’ll either price your window washing and associated services on a per-pane, per hour, or per-employee-hour basis. You might also offer monthly contracts on a flat fee basis.

How much can you charge customers?

Some businesses charge on a per-window-pane basis of about $4 or so, while others think about the time it will take to perform the job and try to make $50-$80 per employee per hour. So if you’re charging out your services on a $60 person/hour basis and you send two workers for a job you expect to take two hours, you’d charge $240 for the job. Here’s an informative article on pricing your services.

How much profit can a window washing business make?

The variables include local competition, the types of businesses and building structures in your area of operation, your sales abilities, and many others. Here’s one web author in the field who estimates that it’s possible to earn $60,000 per year operating a window cleaning business.

How can you make your business more profitable?

There are many associated business activities you could explore to boost sales and net profits. This includes pressure washing of homes and buildings, window tinting and other building janitorial/cleaning services.

Day-to-Day and Growth

What happens during a typical day at a window washing business?

Your typical day might include the following activities.

  • Cold-calling or otherwise attracting new business and marketing your services

  • Scheduling appointments for cost-quoting or washing windows, scheduling employees, and handling on-the-job problems or challenges

  • Buying supplies, renting equipment, invoicing clients, and otherwise conducting day-to-day operations

What are some skills and experiences that will help you build a successful window washing business?

Window washing is considered to be a commodity service, meaning that a window should look just as clean regardless of which commercial service took on the job. Your differentiation will be your sales ability, competitive pricing and attentiveness. You’ll make sure that your cleaning crews arrive as scheduled and do the job properly the first time. You should check with every client to gauge their satisfaction with the job, since their continued business and word-of-mouth is critically helpful in your success.

What is the growth potential for a window washing business?

Your success will only be limited by the competition in your area, the number of potential clients out there, and your sales and marketing efforts and proficiency.

What are some insider tips for jump starting a window washing business?

Start low to the ground. Issues of safety and equipment costs rise with the heights to which you send your people. If you concentrate first on simple one-story or two-story jobs, it will give you a platform for training workers, figuring out pricing and work efficiencies, and building a reputation. This means first going to residences, storefronts, car dealerships, and other structures fairly low to the ground before scaling the heights when you gain more confidence and expertise.

How and when to build a team

While you might start out on your own, you’ll soon see the need for bringing on employees. You might decide that two-person vans and work teams are needed for ultimate job efficiency and safety. If that’s the case, build your employee base with fleet size. But don’t build a workforce too quickly if you can avoid it, because you’ll reduce the need to layoff workers during slow times. Also remember that in many locations window cleaning is more or less seasonal work.

        Part 3 - Action plan to launch your Window Washing business in 90 days

        Nine concrete steps to take you from idea to open business, grouped into 30-day phases. Complete the planner above and we'll highlight what's most important for your situation.

        First 30 days — Foundation

        1. Form your legal entity

          An LLC keeps your personal assets separate from business debts and lawsuits — the most common reason small business owners choose this structure. Sole proprietorships and partnerships do not provide this protection.

        2. Get an EIN and register for taxes

          Apply for your free Employer Identification Number through the IRS, then register for any state or local taxes that apply to your business (sales tax, franchise tax).

        3. Open a business bank account and credit card

          A dedicated business account is required to maintain personal asset protection. Mixing personal and business finances ('piercing the corporate veil') can void your LLC's liability shield.

        4. Set up business accounting

          Recording expenses and income from day one makes tax filing easier and lets you see when the business is actually profitable. Use software (QuickBooks, Wave) or a part-time bookkeeper.

        Days 30–60 — Compliance & Risk

        1. Get permits and licenses

          State and local requirements vary widely. Brick-and-mortar businesses typically need a Certificate of Occupancy; service businesses may need specific professional licensing; food businesses need health permits.

        2. Get business insurance

          General Liability Insurance is the most common starting point. If you'll have employees, most states require Workers' Compensation. Specific industries need additional coverage (product liability, professional liability, etc.).

        Days 60–90 — Launch

        1. Define your brand

          Your brand is how customers perceive and remember you. A clear name, logo, and visual identity make every later marketing decision easier and protect you legally as you grow.

        2. Create your business website

          Every legitimate business needs a website. Social media pages are not a substitute — you don't own the platform. Modern website builders mean you can launch a clean site in a weekend without a developer.

        3. Set up your business phone system

          A dedicated business number keeps your personal life private, makes the business look legitimate, and lets you route calls professionally. Cloud phone services start under $20/month.
