Window Cleaning Equipment & Startup Costs

The gear you actually need to start is shorter and cheaper than most people expect. What costs beginners money is not missing equipment. It is the wrong ladder, mishandled screens, and skipping a five-minute check before the first pass. This is Step 3 of the Window Cleaning Business Series.

Here is the real starter kit, what to deliberately not buy yet, and the small technique details that separate a smooth first week from a $300 argument over a scratched pane.

1, The starter kit that is actually enough

The list is short: a squeegee (channel and rubber), a scrubber or applicator sleeve, a bucket, an A-frame ladder, microfiber cloths or surgical towels, basic dish soap, and a bit of 0000 steel wool for stuck-on residue like paint specks or hard water spots. That is genuinely enough to take on real jobs, and a few hundred dollars covers the whole kit.

Two brands stand out as the affordable, reliable standard: Ettore and Unger. A basic hardware-store squeegee is fine to learn technique on, but most solo cleaners upgrade to one of these fairly quickly once they are doing this for money rather than practice.

2, What to skip until you have volume

The equipment that costs real money (a water-fed pole system, a gutter vacuum, an extension ladder, a dedicated van) is best treated as a "grow into it" purchase, not a day-one requirement. Buying it upfront, before you know your job volume or exactly what kind of properties you will be working on, is a common way to sink cash into gear that sits unused.

On the water-fed pole specifically: it is genuinely worth having eventually. Once you are comfortable with it, it can clean roughly 90% of windows without having to detail away soap residue by hand, and it is much faster on multi-story homes. But it is not how most people start. The common path is learning traditional hand-cleaning first, then adding a pole once speed actually starts limiting how many jobs you can take. Even experienced operators with a pole still clean by hand wherever the pole cannot reach: tight spots, areas near a roof, or anywhere you do not want to soak, like right next to a wood deck.

3, Screens: the thing that eats the most time early on

Screens are consistently the thing that eats the most time on early jobs. They are more fragile than they look, springs can seize or snap, and screens that appear interchangeable between windows on the same house often are not. Mixing them up is one of the most common rookie mistakes, and sorting it out afterward burns real time.

• Reinstall as you go. Clean one window, put its screen back immediately, then move to the next, rather than pulling every screen in the house first and reinstalling them all at the end.
• Match dirt level to method. A quick wipe-down in place works for lightly dirty screens. Heavily soiled ones are worth pulling for a proper hose-and-scrub pass.
• Free a seized screen from the top. A stuck screen usually just needs pressure at the top to un-stick before it will pull free at the bottom.
• Check for blinds mounted over the window ahead of time. Some need to come down for screen or window access, and that is easier for the homeowner to handle before you arrive than for you to navigate on-site.

That extra time is also why screens belong on the quote as their own line item rather than folded into the base rate, which Step 4 on pricing covers.

4, The pre-job check that saves you from expensive disputes

The most expensive mistakes on a window cleaning job rarely come from bad squeegee technique. They happen before the first pass, from skipping a quick check of the glass and its surroundings. A scratch, a hard water etch or a drip mark that was already there before you started is a lot easier to prove was not your fault if you looked for it, and photographed it, first.

• Never use a blade on tempered glass without first checking for fabrication debris or existing scratches
• Test technique on a small corner before running it across a whole pane
• Check for hard water damage before you start, so you are not blamed for etching that predates the job
• Watch where dirty runoff water goes. On fresh paint, stucco or an untreated wood sill, it can leave its own mark
• Move or tarp anything sitting under interior windows before you start detailing above it

The photos cover damage you did not cause. Damage you did cause is a separate question, because a scratch from technique may not be covered by general liability at all. Step 2 on insurance explains that gap.

5, Ladder and heat safety

Two safety basics are worth stating plainly. First, do not cheap out on a ladder, and do not use one that is old or damaged. A ladder that kinks, buckles or is not properly secured is a genuine injury risk, not just an inconvenience, and extension ladders on windy days need to be secured before you climb, not after.

Second, if you are working through summer in a hot climate, heat is a real occupational hazard on this job, not a minor discomfort. Anyone working full days outdoors from spring through fall needs to treat it as a daily consideration: loose, moisture-wicking clothing, changing it out during the day, drinking at least a bottle of water every hour, and a small amount of salt intake to help offset what is lost to sweat. Recognizing the difference between simply feeling sun-sick and an actual heat emergency is a skill worth taking seriously once temperatures climb.

Frequently asked questions

What equipment do I need to start a window cleaning business?

A squeegee with channel and rubber, a scrubber or applicator sleeve, a bucket, an A-frame ladder, microfiber cloths or surgical towels, basic dish soap, and 0000 steel wool for stuck-on residue. That covers the large majority of standard residential jobs and typically costs a few hundred dollars total.

Do I need a water-fed pole to start a window cleaning business?

No. Most operators start with traditional hand-cleaning and add a water-fed pole system once they have steady volume and need to move faster. A water-fed pole can handle roughly 90% of windows once you are comfortable with it, but traditional technique is still needed for tight spots, areas you cannot get a pole to, and places you do not want to soak, like near a wood deck.

What brands of squeegees do window cleaners actually recommend?

Ettore and Unger are widely regarded as affordable, reliable brands. A basic hardware-store squeegee works fine to learn technique on, but most operators upgrade to one of these fairly quickly.

Why do screens take so long on early window cleaning jobs?

Screens are fragile, their springs can seize or break, and screens that look interchangeable are often matched to one specific window, so mixing them up is a common early mistake. Reinstalling each screen immediately after cleaning that window, instead of pulling every screen in the house first, saves significant time.
