How to Get Customers as a Window Cleaner

Why “how to get customers as a window cleaner” is a very simple question is because there is only one way to get customers as a window cleaning company. Every other option you might hear is therefore not true. I can tell you that as a school teaching people to build window cleaning companies – and to be more specific, almost 400 window cleaner companies with more than 150,000 customers combined – they all got the same question from day one: how to get customers as a window cleaner. And at the end of the day, now they all know there’s only one way of getting these customers, and the keyword and answer is sales. Sales is the only way of getting customers, and that’s why it matters to be good at sales.

How do I promote my window cleaning business?

Some people say that there are never stupid questions, but if you’re starting a window cleaning business and want to know how to get customers as a window cleaner – and you’re asking how to promote your window cleaning business – this might be a stupid question. What you’d like to ask is how you become great at selling window cleaning subscriptions, and after you’ve learned that and done the cold sales, you can begin to promote.

Like a football club wants to see a player in action before promoting him, I guess…

Example of the only way to get customers as a window cleaner

We already learned that there is only one way to get customers as a window cleaner, and now I want to showcase how many customers you can actually make from sales.

Let’s say I personally promote you, and you gain 1000 leads – like 1000 people getting in touch with your business, possibly interested in your service.

Remember: Promotion can only generate leads – never sales.

Sales happen when you’re doing the final selling, whether it’s online or physically.

And the truth is that most people in the world will never pay for something they don’t know. And when they know about it, that’s the promotion part – whether it’s good or bad promotion.

Now, we’re going to look at why it matters to be very great at selling, now that it’s the only way in the world to get more window cleaning customers.

Back to the 1000 leads you just got from my promotion: let’s say you’re the average Joe in the space, who wants to fast forward without calculating and planning too much – which is why you never learned how to be great at sales before jumping into your new business.

Let’s say you’re closing 10% with an average price of €30, cleaned every 8 weeks.

That’s €18,000 a year and €1,500 per month you make right there.

What will happen if I gave those leads to my window cleaner who has been trained step-by-step in how to close high-paying subscription customers?

Let’s go with the real numbers:

The average closing rate for that type of skilled profile is 60%, and the average price is €45, cleaned every 6 weeks. Understand why closing 60% leads instead of 100% is a better business.

That’s €270,000 a year and €22,500 a month.

This is just an example, and I know it sounds wild – but just do the simple math.

That’s why it’s so frustrating for me when I see people asking “how to get customers as a window cleaner” and all types of promotion ideas pop up – because it’s such a wrong place to start.

No, it’s really not about just jumping into it with no brain

So we’re still talking about how to get customers as a window cleaner, and yes, some get the point – that you should be a great salesperson first – but might say: “you just need to jump into it and learn”, and… it’s really not that simple.

If you were selling a potato – fair enough, just sell it in multiple ways and prices and see if you’re making money on it, if you really don’t want to calculate the price metrics.

But here, we’re not talking about selling a potato.

We’re talking about selling you – and you should not be sold for anything.

It’s such a common mistake to say “but hey, I have almost no expenses, it’s just me, so prices don’t matter so much as long as I’m happy with my hourly wage.”

That’s totally fine if you love what you’re doing and don’t care whether it becomes a great business or not.

But at the same time, it’s completely wrong if you want to build a professional window cleaning business – which I think you do, since you’re interested in how to get customers as a window cleaner.

When setting prices as a startup and asking how to get customers as a window cleaner with the vision to build a long-lasting company, you really need to learn how to sell customers on example prices that not only allow you to make a living – but that also allow employees to make a living and generate profit for you.

Otherwise, you can end up in a situation where your future employees are not even profitable, because you set the wrong prices.

The biggest window cleaner growth hack?

I think you get the point about how important it is to be very good at sales – when it comes to prices, your closing rate (how many leads you turn into customers), and also the frequency of how often they get cleaned / how often they pay you.

Of course, sales and sales training is a never-ending journey. Like with other professionals, you can always get better – the world is changing every minute.

But let’s say “you got that.”

In fact, that’s why we at Windowcleanerschool.com always train our people and companies to be very successful with sales before we move on to marketing strategies, which bring in a lot of leads.

And one more very critical thing you have to learn and work on before starting up marketing in the field is the king of marketing – and every business in the world’s wildest dream: to have more of it.

Because when you have it, it feels like new customers come in almost automatically.

And not just customers – we’re talking about the best customers.

So when you ask how to get customers as a window cleaner, these are the customers you really want.

They are the most loyal.

They trust the prices you give.

They trust the service you have.

They’re already in love with your brand.

This type of customer comes from only one sweet source: organic growth – meaning customers who refer other customers.

When 1 customer over time turns into 2 customers, it’s just a matter of time before you have a great business.

We teach people a lot of triggers to reach a high organic growth rate – because when 100 customers over time turn into 1000 customers, without spending any money on getting them, it almost feels too good to be true and that’s how to get customers as a window cleaner.

But that doesn’t mean you shouldn’t do any marketing.

What it does mean is that it’s very important to build such a great service – with the right triggers – that customers naturally want to turn themselves into more paying customers.

Great marketing strategies for a window cleaning business?

There’s a ton of ways to bring in new customers to your window cleaning business – once you learn how to sell great window cleaning subscriptions.

Of course, if we’re talking about marketing strategies that cost money, such as banners, Facebook marketing etc., the better a salesperson you are, the more effective the marketing channel becomes.

If we go with the same example – the one closing 10% of leads at an average €30 cleaning every 8 weeks, versus the one making €45 average, every 6 weeks, and closing 60%:

If they both use €400 on Facebook marketing and gain 100 leads:

  • The bad seller (10% low price guy) gets €300 upfront (loses €100 upfront) and €2,400 in yearly revenue.
  • The great subscription seller gets €2,700 upfront (gains €2,300 upfront) and €27,000 in yearly revenue.

And not to mention if the great seller also has great organic growth, where 1 customer turns into 2 over time – Facebook becomes even more powerful.

Meanwhile, we also see bad sellers lose more customers than they gain from organic growth – so the bad seller example can become even worse.

What it all means, in the end, is that when you learn how to prepare your company right – as we do for a living here at Windowcleanerschool.com – we can succeed with almost all other marketing actions, no matter if we’re talking about influencers, Facebook marketing, sponsored deals, local deals, strategic partnerships, and so on.

So what others call “bad ways to get customers” – we can make a great profit out of.

But in the end, we’re a physically represented business – so all strategies should be applied locally.

Regarding specific marketing actions, that might be an article in itself.
