The School’s Story: Back Then to Now

Five years ago, as a window cleaning company, you had no training center for your employees. No matter that you were a window cleaner and never claimed to be a trainer — you still had to train your own staff. They could also try to learn something on YouTube, but no one really succeeded with the same great, fast, high-quality and effective structure this way.

Windowcleanerschool started as a physical school in Denmark back then, assembling the very best team to make this possible — but still aware there was a lot to learn regarding education. In the next two years, more than 100 people were educated through the school. They gained strong craftsmanship, but many wanted to start their own businesses and experience the freedom it brings if you learn how to build it right from the very start, without mistakes.

Fast forward five years, the school has now helped build more than 350 great companies, with local people hiring other locals. The passion of the founder team of the school has always been to make a big impact in the world, which is why we have always known that we wanted more people to be able to join the school worldwide. That’s why, over the last three years, we have invested everything in building comprehensive software and online training — step-by-step tasks to build a successful window cleaning company., which is now available for you. We don’t want your money, but your commitment — because that’s what makes everything go around.

Today, we use Denmark as our flagship, where our partners from all around the globe can sometimes fly in to be part of the physical training and see where it all started. Of course, you may not yet see the meaning of traveling to Denmark for window cleaning training, but when we are successful together, you might think it would be nice — and then you are more than welcome as a partner.

Frequently Asked Questions

How do I get my first 10 customers?

We walk you through it step by step. From the exact pitch, to where and how to approach people — everything is laid out clearly. Most of our partners get their first 10 customers within the first week. And it doesn’t stop there: you’ll go through several levels of sales training over time — learning how to improve pricing, frequency, conversion rates, and even close high-value routes. It's a progressive system that builds your confidence and skills every step of the way.

When is the best time to start?

If you have 10+ hours/week and motivation, now is ideal. The sooner you start, the sooner your systems, income, and growth begin compounding.

Will this work for me if I'm not a "salesperson"?

Definitely. Most of our top performers had no sales background. With our training, they now close deals confidently — and you will too. Learn how in Learning Hub.

Can I get rich doing this?

Yes. Our top-performing partners sign up over €700,000/annually recurring revenue within 2 years - not by working harder, but by using systems, hiring right, and following our proven steps. Learn how in Learning Hub.

Is the market already saturated?

No. Most areas are underserved - not because of lack of opportunity, but because most people don’t know how to run this the smart way. We change that. Learn how in Learning Hub.

Can this become passive income?

Yes. We’ve helped many partners hire and step back with systems for staff training, scheduling, and even sales. That’s built into the plan. Learn how in Learning Hub.

Will I be working alone?

Not really. While you're the business owner, we’re behind you daily through community, messaging support, and coaching. You’re in business for yourself, not by yourself. Learn how in Learning Hub.
