DIY or Hire a Pro? The Honest Answer from a 25-Year Window Cleaner
Quick answer: If your windows are easy to reach, you have the right tools, and you genuinely want to learn proper technique, DIY can work. But for most homeowners, hiring a professional saves time, delivers better results, and protects your windows. Here is how to decide.
The Two Questions Nobody Asks
Before you grab a squeegee or pick up the phone, I want you to consider two questions most people skip.
First: Can I do this myself?
Technically, yes. Window cleaning is not brain surgery. But cleaning windows properly requires specific technique, the right tools, and physical effort most people underestimate.
Second: Do I actually want to do this myself?
This is the question that matters. Because even if you can clean your own windows, spending your Saturday wrestling with a squeegee, aching afterwards, and still finding streaks is not everyone's idea of time well spent.
I have cleaned windows professionally for 25 years. I started in Melbourne in 1999 and have run my Vienna-based business since 2010. I love window cleaning. But I understand why most of my clients would rather spend their weekends doing something else.
What DIY Window Cleaning Actually Involves
Let me be honest about what you are signing up for.
Time commitment: A typical Vienna apartment with 10-15 windows takes 3-4 hours to clean properly, inside and out. A house with 20+ windows? Easily a full day. And that is assuming you already know what you are doing.
Physical demand: Window cleaning is surprisingly hard on your body. Reaching, stretching, climbing, squeezing. Most of my first-time DIY clients tell me they ached for days afterwards.
Equipment costs: A quality squeegee, T-bar applicator, microfiber covers, extension pole, bucket, and proper detergent will cost €100-200 upfront. Cheap tools from the hardware store create more problems than they solve.
The learning curve: Here is what nobody tells you. The squeegee technique that looks simple is actually precise. The angle matters (45 degrees, not flat). The pressure matters. The overlap matters. The order of strokes matters. Get any of these wrong and you leave streaks.
I have spent 25 years perfecting these movements. Most DIY attempts leave marks because the technique takes time to develop.
The Real Cost of "Doing It Yourself"
Most people calculate DIY savings incorrectly.
They think: Professional cleaning costs €200. I will save €200.
They forget: Their time has value. The equipment costs money. The frustration when streaks appear has a cost too.
A more honest calculation:
- Equipment: €150 (one-time, but needs replacing)
- Your time: 4-6 hours × your hourly value
- Physical recovery: That evening on the couch instead of doing something you enjoy
- Result quality: Probably 60-70% of what a professional achieves
For windows you can easily reach and clean twice per year, DIY might make sense. For anything else, the math changes quickly.
When DIY Makes Sense
I am not here to tell you that you must hire a professional. For some situations, DIY is perfectly reasonable.
DIY can work when:
- Your windows are all at ground level or easily reachable
- You have (or will invest in) proper tools
- You genuinely want to learn the technique
- You have the time and physical ability
- You are willing to accept that results may not be perfect
If this sounds like you, I have created a free training video that teaches the essential technique. It covers the three squeegee turns, proper soap-water ratio, and the agitation method that prevents streaks. You can access it at orloffs.com/manifesto.
When Hiring a Professional Makes Sense
For most of my Vienna clients, professional window cleaning is about three things: time, quality, and peace of mind.
Hire a professional when:
- You have high windows, skylights, or difficult access points
- Safety is a concern (ladders, balconies, steep angles)
- Your windows have hard water stains, mineral deposits, or years of buildup
- You want streak-free results without the learning curve
- Your time is more valuable than the cost of the service
- You simply do not want to do it yourself
There is no shame in that last point. I love cooking, but I also eat at restaurants. Some things are better left to people who do them every day.
What a Professional Actually Does
The difference between DIY and professional results comes down to technique, tools, and experience.
Technique: After 25 years, my hands know exactly how much pressure to apply, what angle to hold the squeegee, and how to execute each stroke without leaving a trace. This muscle memory takes years to develop. You cannot learn it from watching a YouTube video.
Tools: I use professional-grade squeegees with precision-ground rubber, T-bar applicators with microfiber covers, purified water systems for exterior cleaning, and extension poles that reach safely. These tools cost thousands of euros and are not available at Bauhaus.
Experience: I know that Austrian hard water leaves specific mineral deposits. I know that certain window coatings require different cleaning approaches. I know how to clean around delicate seals without damaging them. Every property teaches me something new.
The result: Crystal-clear glass with no streaks, no drips, no residue. Frames and seals cleaned and checked. A transformation that makes you notice your view again.
The Transformation Nobody Expects
Here is something my clients tell me after their first professional clean: they did not realise how dirty their windows actually were.
When you look through slightly dirty glass every day, your eyes adjust. You stop noticing the film, the water spots, the gradual dimming of light. It becomes normal.
Then the windows get cleaned properly, and everything changes. Light floods in. Colours look brighter. The view you paid for when you bought your home suddenly appears again.
One client told me: "I thought my apartment was dark. Turns out my windows were just filthy."
That transformation is worth more than the cost of the service.
How to Choose a Professional Window Cleaner
If you decide to hire a professional, here is what to look for.
Experience matters. Ask how long they have been cleaning windows. This trade takes years to master.
Reviews tell the truth. Check Google reviews. Look for consistency: does every client mention the same quality?
Fixed quotes protect you. A professional should assess your property and give a fixed price, not an hourly rate that can balloon.
Insurance is essential. Make sure they carry liability insurance. Accidents happen, and you do not want to be responsible.
Availability says something. The best window cleaners are booked in advance. If someone can come tomorrow, ask why their calendar is empty.

Frequently Asked Questions
Is professional window cleaning worth the cost?
For most homeowners, yes. The time you save (4-8 hours), the quality difference, and the safety of high or difficult windows make professional cleaning excellent value. Most clients book twice per year.
How often should I have my windows professionally cleaned?
Most Vienna homes benefit from cleaning twice per year: spring and autumn. Properties near busy roads or with large glass surfaces may need quarterly cleaning.
What does a professional do that I cannot?
Professionals bring proper technique (specific angles and movements), professional-grade tools, safety equipment, knowledge of hard water stains, and the ability to clean frames and seals. The result is streak-free glass with no compromises.
How much does professional window cleaning cost in Vienna?
Pricing ranges from €150 for small apartments to €500+ for larger properties. It depends on window count, accessibility, and condition. I provide fixed quotes after assessing your home.
Why do my windows streak when I clean them myself?
Streaks come from too much cleaning product, wrong squeegee angle, or incorrect technique. Professionals use minimal soap, hold the squeegee at 45 degrees, and execute specific overlapping strokes that prevent marks.
