Window Cleaning Side Hustle

How to start
- 01 Buy a starter kit before anything else: a quality squeegee set, scrubber, extension pole, and cleaning solution. A basic ladder if you don't own one. Total outlay is low.
- 02 Get general liability insurance before taking paid work. It's affordable on a monthly basis and non-negotiable once you're on someone else's property.
- 03 Start with your own street. Offer a neighbour a discounted first clean, get a before/after photo, and use that to post on Nextdoor.
- 04 Door-to-door flyers with a seasonal angle like 'spring clean your windows' in residential neighbourhoods is the fastest path to a first booking. Same week is realistic.
- 05 Price per window or per job, not hourly. Clients want to know the cost upfront before you arrive.
- 06 Push for recurring bookings from day one. A client who books quarterly is worth far more than a one-time clean.
Pros
- + Very fast to start. Equipment is affordable, no certification needed, and first clients are reachable within days via door-to-door.
- + More year-round than lawn care or snow removal. Spring and fall are peak, but recurring clients provide steady work in summer and milder winters.
- + Recurring contract model. Quarterly or bi-annual clients pay without re-selling.
- + High effective hourly rate once efficient. Experienced operators move quickly.
- + Completely AI-proof with structural demand that won't change
Cons
- − Physically demanding. Ladder work, outdoor conditions, and repetitive motion.
- − Operating without insurance is a serious risk. A cracked window or a fall on a client's property is your problem without coverage.
- − Seasonal dips in cold climates. Below-freezing temperatures make exterior work impractical.
- − Competition from established operators in any suburban area. You'll need to undercut or out-service them early on.
- − High-rise and commercial work requires specialist equipment and certifications. Stay residential until you're established.
Skills needed
Where to work
Who this is actually for
You need to be physically capable, live in a suburban area with residential homes, and be comfortable working on a ladder. The work isn’t technically complex, the technique for streak-free windows is learnable in a few hours of practice, but it is outdoor, physical, and requires showing up reliably on a schedule. If you’re in a climate with cold winters, you’ll have slower months, but this is significantly more year-round than lawn care or snow removal.
No trade certification exists for residential window cleaning in the US or most other markets. A general business licence from your local municipality and general liability insurance are all you need to operate legitimately.
Starting residential, not commercial
There are two different markets here and they’re not interchangeable for a beginner.
Residential window cleaning, private homes, has a low barrier to entry, fast client acquisition, and clear pricing. You show up, clean the windows, collect payment, and ask about recurring service. The homeowner is the decision-maker and the conversation is simple.
Commercial window cleaning, storefronts, offices, multi-storey buildings, involves longer sales cycles, formal quotes, multiple stakeholders, and for anything above a few storeys, specialised equipment and safety certifications like OSHA compliance and rope descent training. High-rise work requires investment and credentials that aren’t appropriate for a side hustle entry point.
Start entirely residential. After several months of consistent work and a portfolio of satisfied clients, adding low-rise commercial accounts like ground-floor retail and small offices is a natural expansion that uses the same equipment and doesn’t require additional certification.
Equipment: what you actually need
A quality squeegee set from a professional brand, a scrubber or applicator sleeve, extension pole for ground-floor reach, cleaning solution, and a bucket. A six to twelve foot ladder covers the vast majority of residential work. That’s the full starting kit.
Don’t buy the cheapest squeegee available. Budget squeegees leave streaks and require more passes, which costs you time on every job. Professional tools from established brands produce better results faster and pay for themselves quickly in efficiency.
A water-fed pole, a system that feeds purified water through a brush at the end of an extending pole, is the tool of choice for second-storey-and-above exterior work. It eliminates ladder risk for high windows and produces a clean finish as the purified water dries without spots. It’s not essential to start, but worth considering once you’re doing consistent volume.
Getting first clients
Door-to-door flyers and direct knocking in residential neighbourhoods is the fastest method. A simple offer, a flat price for a standard home’s exterior windows with a first-time discount, is enough. Spring is the peak demand period when homeowners are actively thinking about cleaning after winter. Flyers distributed in a neighbourhood during March or April will produce same-week bookings if the density of homes is reasonable.
Nextdoor is the second most effective channel for a new operator. Post an introduction in the local community tab with a clear offer and a photo. Respond promptly when neighbours ask for window cleaner recommendations because those threads convert well.
Facebook local groups follow a similar pattern. Before-and-after photos are significantly more compelling than text-only posts. The visual contrast is what motivates people to reach out.
Recurring clients are the business
A homeowner who books once is useful. A homeowner who books every quarter for the next three years is the foundation of a stable income. Every job should end with a direct question: would you like to schedule the next clean now? Quarterly bookings are standard, and some clients prefer twice-yearly.
Recurring clients require no re-acquisition marketing. They trust you, they know your price, and the only variable is whether you show up reliably. A roster of fifteen to twenty recurring residential accounts covers most of a side hustler’s target income without any additional outreach.
The fastest way to lose a recurring client is inconsistency: showing up late, missing a scheduled visit without notice, or producing visibly different quality from one visit to the next. The bar to retain a happy client is low. Show up when you said you would and leave the windows clean.
Insurance is not optional
General liability insurance for a solo window cleaning operator is affordable on a monthly basis. Some providers offer pay-per-day policies for part-time operators at an even lower entry cost. The coverage protects you if you crack a window, damage a frame, or if a client slips on water tracked in from your equipment.
Get insurance before taking your first paid job. A single incident without coverage can cost more than a full season’s earnings, and clients with higher-value properties will sometimes ask to see proof of insurance before letting you work.
