25 Window Cleaner Interview Questions and Answers

Most people don’t think about the people who clean the windows of tall buildings, but these professionals play an important role in keeping our cities safe and clean. If you’re looking for a job as a window cleaner, you can expect to be asked a range of questions about your experience, safety protocols, and physical abilities.

In this guide, we’ve compiled a list of common window cleaner interview questions and answers to help you prepare for your next job interview.

1. Are you comfortable working at great heights?

Window cleaning often involves working at great heights, so the interviewer wants to make sure you’re comfortable with this. If you have any experience working at high altitudes, mention it in your answer.

Example: “Absolutely! I have been a window cleaner for over five years and in that time I have become very comfortable working at great heights. I understand the importance of safety when it comes to my job, so I always make sure to use the proper equipment and take all necessary precautions before starting any job. I also have experience using ladders, scaffolding, and other tools to help me reach difficult-to-access windows. I am confident that I can handle any job safely and efficiently no matter how high up the windows may be.”

2. What are some of the most important safety precautions you take when working at heights?

Employers ask this question to make sure you are following proper safety procedures when working at heights. They want to know that you have experience with the necessary precautions and can implement them in your work. In your answer, explain what steps you take to ensure your own safety as well as the safety of others around you.

Example: “Safety is always my top priority when I am working at heights. To ensure the safety of myself and those around me, I take a number of precautions.

Firstly, I always make sure that I have the right equipment for the job. This includes wearing a harness and using ladders or scaffolding that are in good condition and meet all relevant safety standards.

Secondly, I assess the area before I start work to identify any potential hazards such as loose wires or slippery surfaces. If there are any risks present, I will take steps to reduce them, such as putting up warning signs or securing items with rope.

Thirdly, I never attempt to clean windows on my own if they are more than two stories high. Instead, I will enlist the help of a colleague who has experience in this type of work.”

3. How would you clean a window that is very dirty?

This question can help the interviewer understand your cleaning process and how you prioritize tasks. Use examples from previous experience to show that you are organized, detail-oriented and able to work independently.

Example: “I understand that cleaning a window that is very dirty can be challenging. However, I have the experience and knowledge necessary to do so effectively.

My first step would be to assess the condition of the window in order to determine what type of cleaner and tools are needed for the job. Depending on the level of dirtiness, I may use a mild detergent or a stronger solution such as vinegar or ammonia. After selecting the appropriate cleaner, I would then use a soft cloth or sponge to apply it to the window. If there are any stubborn stains, I would use a scraper to remove them.

Once the window has been cleaned, I would rinse off any remaining residue with clean water and dry the surface using a squeegee or lint-free cloth. Finally, I would inspect the window to ensure that it is completely clean and free from streaks.”

4. What is your process for maintaining your equipment?

Window cleaning equipment is often expensive, and employers want to know that you take care of your tools. They also want to make sure you have the skills necessary to maintain their own equipment. In your answer, explain how you clean your tools and what materials you use.

Example: “I understand the importance of maintaining my equipment in order to ensure a safe and efficient window cleaning job. My process for maintaining my equipment includes regularly inspecting it for any signs of wear or damage, as well as ensuring that all parts are properly lubricated and functioning correctly. I also make sure to clean and store my tools after each use, so they’re always ready for the next job. Finally, I keep an inventory of spare parts on hand in case something needs to be replaced. This way, I can quickly get back to work without having to wait for new parts to arrive.”

5. Provide an example of a time when you had to deal with a difficult customer or client.

Employers ask this question to see how you handle conflict. They want to know that you can remain calm and professional when faced with a challenging situation. In your answer, try to focus on the steps you took to resolve the issue.

Example: “I have had to deal with difficult customers or clients in the past. One example that stands out was when I was working as a window cleaner for an apartment complex.

One of the tenants had requested a special cleaning job, which required me to work outside of my normal hours. After completing the job and submitting the invoice, the tenant refused to pay the full amount due to what they perceived as inadequate service.

I knew that I had done the best job possible and so I calmly explained this to the tenant. I also offered to come back and do any additional work that might be necessary at no extra cost. In the end, the tenant agreed to pay the full amount and thanked me for my professionalism and willingness to go above and beyond.

This experience taught me how important it is to remain professional and courteous even when dealing with difficult customers or clients. It also reinforced my belief that communication is key when resolving conflicts.”

6. If you were given a window cleaning route that took you to five buildings on a given day, how would you prioritize the windows you clean?

This question can help the interviewer understand how you plan your day and prioritize tasks. Use examples from previous experience to show that you know how to manage your time and get work done efficiently.

Example: “If I were given a window cleaning route that took me to five buildings on a given day, I would prioritize the windows based on their size and location. First, I would start with the largest windows as they take more time to clean than smaller ones. Then, I would move onto the windows located in high traffic areas such as lobbies or entrances, since these are the most visible and need to be cleaned thoroughly. After that, I would focus on the windows in less trafficked areas of the building. Finally, I would make sure to check all the windows for any dirt or debris that may have been missed during my initial cleaning process. By following this method, I can ensure that all windows are properly cleaned and that no area is overlooked.”

7. What would you do if you were running behind on your schedule and you had to skip a window?

Employers want to know that you can prioritize your work and make decisions quickly. They also want to know how you would handle the situation if it happened during an important job. In your answer, explain what steps you would take to ensure you complete the skipped window as soon as possible.

Example: “If I were running behind on my schedule and had to skip a window, I would prioritize the windows that need to be cleaned first. I understand that time is of the essence when it comes to window cleaning, so I would make sure to assess each window in order to determine which ones are most important to clean. If there are any windows with particularly difficult stains or dirt buildup, those should be taken care of first.

I also believe in being organized and efficient while working. This means that I would plan out my route ahead of time and make sure that I am not wasting any time by going back and forth between different areas. Finally, if I still find myself running behind, I would communicate this to the customer and let them know what I’m doing to catch up.”

8. How well can you see through a window that you have just cleaned?

This question is a test of your ability to see clearly through the windows you clean. Employers ask this question to make sure that you are able to see well enough to avoid any accidents while working on their building’s windows. To answer this question, explain how you can see through a window after cleaning it and what steps you take to ensure you’re seeing clearly before moving on to another window.

Example: “I have been a window cleaner for many years and I take great pride in my work. When it comes to seeing through the windows that I have just cleaned, I can confidently say that I do an excellent job. My attention to detail is second to none and I make sure to leave no streaks or smudges behind. After cleaning each window, I always take a few steps back to ensure that I have done a thorough job. This allows me to see if there are any areas that need further attention before I move on to the next window. As a result, I am able to provide customers with sparkling clean windows that they can easily look through.”

9. Do you have a method for remembering all of the buildings you have to visit on a given day?

This question can help the interviewer determine how organized you are and whether you have a system for keeping track of your work. Your answer should show that you’re detail-oriented, organized and able to prioritize tasks.

Example: “Yes, I have a method for remembering all of the buildings I need to visit on a given day. Before starting my route, I create a checklist of each building and its address. This way, I can easily keep track of which buildings I’ve visited and which ones are left. I also take pictures of each building so that I can refer back to them if needed. Finally, I use an app on my phone to map out my route in advance, so I know exactly where I need to go and how long it will take me. By using these methods, I am able to stay organized and efficient throughout my workday.”

10. When performing a job for a long-term client, do you have any strategies for building a positive relationship?

Employers may ask this question to learn more about your interpersonal skills and how you interact with clients. When answering, it can be helpful to mention a specific strategy or two that you use to build positive relationships with long-term clients.

Example: “Building a positive relationship with long-term clients is very important to me. I believe that communication and trust are key components of any successful working relationship. When working with a long-term client, I make sure to keep them informed throughout the job, so they know what progress has been made and what still needs to be done. I also take the time to listen to their feedback and adjust my work accordingly.

I always strive to provide quality service and exceed expectations. If there’s ever an issue or concern, I address it promptly and professionally. This helps build trust between myself and the client, which can lead to a more productive and enjoyable working experience for both parties. Finally, I like to stay in touch after the job is complete, just to check in and see how things are going.”

11. We want to improve our environmental sustainability. How would you reduce the amount of waste you produce on a daily basis?

Window cleaners often produce a lot of waste, so an employer may ask this question to see if you have any ideas for reducing the amount of trash you generate. In your answer, explain how you would reduce the amount of waste you create and what steps you would take to implement these changes in your daily routine.

Example: “As a Window Cleaner, I understand the importance of reducing waste and improving environmental sustainability. To reduce the amount of waste I produce on a daily basis, I would start by using eco-friendly cleaning products whenever possible. These products are designed to be biodegradable, non-toxic, and free from harsh chemicals. This way, any runoff or residue can be safely disposed of without harming the environment.

I would also ensure that all materials used for window cleaning are reused as much as possible. For example, instead of throwing away old rags after each job, I would wash them in order to reuse them multiple times. This not only reduces waste but also helps me save money in the long run.”

12. Describe your experience with using high-powered vacuums.

This question can help the interviewer determine your experience with a specific tool that’s commonly used in window cleaning. High-powered vacuums are often necessary for large windows and other surfaces, so it’s important to show you have the skills needed to use one effectively.

Example: “I have extensive experience with using high-powered vacuums. I have been a professional window cleaner for the past five years and during that time, I’ve used various types of vacuum cleaners to clean windows. I’m familiar with all the safety protocols associated with operating these machines and understand how to use them properly.

In addition, I’m also experienced in cleaning windows with water fed poles, which require the use of high-powered vacuums to remove dirt and debris from hard-to-reach areas. I’m confident in my ability to maneuver the vacuum around tight spaces without damaging the glass or surrounding surfaces.”

13. What makes you stand out from other window cleaners?

Employers ask this question to learn more about your skills and experience. They want to know what makes you unique from other applicants. When answering, think of a skill or quality that sets you apart from others. You can also mention any certifications you have.

Example: “I believe my experience and dedication to the job makes me stand out from other window cleaners. I have been in the window cleaning industry for over 10 years, so I am very familiar with all of the necessary techniques and tools needed for a successful job. My attention to detail is one of my strongest qualities; I take great pride in ensuring that every window I clean is spotless and streak-free.

In addition, I always strive to provide excellent customer service. I understand how important it is to make sure clients are satisfied with the results of my work, so I go above and beyond to ensure they are happy with the end product. I also stay up to date on the latest technology and products available to help improve efficiency and safety while window cleaning.”

14. Which window cleaning tools do you prefer to use?

This question can help the interviewer learn more about your experience with different tools and how you use them. You can answer this question by listing the tools you have used in previous jobs and explaining why you prefer those over others.

Example: “I have a wide range of window cleaning tools that I prefer to use. My go-to tool is a squeegee, as it’s the most effective way to quickly and efficiently clean windows. I also like to use microfiber cloths for polishing the glass after using the squeegee. For hard-to-reach areas, I like to use an extendable pole with a brush attachment. This allows me to reach high windows without having to climb up ladders or scaffolding. Finally, I always make sure to have a bucket of soapy water on hand for when I need to scrub away stubborn dirt and grime.”

15. What do you think is the most important part of window cleaning?

This question is a great way for employers to learn more about your skills and experience. They may ask this question to see if you have the same priorities as they do. When answering, it can be helpful to mention something that you feel strongly about or that you are particularly good at.

Example: “I believe the most important part of window cleaning is being meticulous and thorough. It’s essential to pay attention to every detail when it comes to window cleaning, from scrubbing off dirt and grime to ensuring that all streaks are removed. I also think it’s important to be organized and efficient in order to get the job done quickly and correctly. Finally, safety should always be a priority when working with ladders or other equipment.”

16. How often should windows be cleaned?

This question can help the interviewer determine how much experience you have with window cleaning. It’s important to show that you know when windows should be cleaned and how often they need to be done. You can answer this question by giving a specific time frame for when you clean windows, such as weekly or monthly.

Example: “Windows should be cleaned on a regular basis to ensure they are free of dirt and debris. Depending on the environment, windows may need to be cleaned more or less frequently. For example, if the windows are exposed to direct sunlight for long periods of time, then they will require more frequent cleaning in order to prevent dust and grime from accumulating. If the windows are located in an area with minimal exposure to the elements, then they can typically be cleaned every few weeks or months. I have extensive experience in window cleaning and understand the importance of maintaining clean windows for both aesthetic and safety reasons.”

17. There is a streak on a recently cleaned window. How would you resolve this?

This question is an opportunity to show your problem-solving skills. You can answer this question by describing the steps you would take to resolve the issue and how you would ensure it doesn’t happen again.

Example: “I understand the importance of providing a streak-free window cleaning service. To resolve this issue, I would first assess the situation to determine what caused the streak in the first place. Was it an incorrect cleaning solution? Was there too much water used? Once I have identified the cause of the streak, I can take the appropriate steps to rectify the problem.

If the streak is due to an incorrect cleaning solution, I will use the correct one and re-clean the window until the streak disappears. If the streak is due to excess water, I will dry the window with a lint-free cloth and then apply a polishing agent to bring out the shine. Finally, I will inspect the window for any other imperfections that may need attention.

My experience as a Window Cleaner has taught me how to provide quality results quickly and efficiently. I am confident that I can solve any streak-related issues that arise on the job.”

18. Describe your experience using different types of ladders and scaffolding.

Employers ask this question to make sure you have the experience and skills necessary to complete your job duties safely. When answering, try to highlight any previous training or certifications you may have in using ladders and scaffolding.

Example: “I have extensive experience using ladders and scaffolding for window cleaning. I am very familiar with the safety protocols associated with these tools, and I always take extra precautions to ensure that I’m working safely and securely.

I have used both step ladders and extension ladders in my previous jobs. With either type of ladder, I make sure to inspect it before each use to ensure that all parts are secure and functioning properly. I also check the area around the ladder to make sure there is nothing blocking my path or creating a potential hazard.

When it comes to scaffolding, I have worked on both stationary and mobile units. I understand how to assemble them correctly and how to adjust the height as needed. I also know how to secure the scaffolding so that it remains stable while I work.”

19. What do you think is the most difficult part about window cleaning?

This question can help the interviewer get a better idea of your experience and how you handle challenges. You can answer this question by describing a time when you faced a challenge with window cleaning, what you did to overcome it and what skills or knowledge helped you succeed.

As an experienced Window Cleaner, I understand this challenge and have developed techniques to ensure that my work is always up to standard.

I also take pride in making sure that all safety protocols are followed when working on ladders and scaffolding. I am very familiar with OSHA regulations and make sure that I follow them closely while on the job. This helps me to provide a safe environment for both myself and anyone else who may be around during the window cleaning process.”

20. How would you clean a large building with many windows?

This question can help the interviewer understand your process for completing a large project. Use examples from previous experience to highlight your ability to work independently and efficiently.

Example: “I have extensive experience in window cleaning and understand the importance of a thorough job. When it comes to cleaning large buildings with many windows, I approach the task methodically and systematically. First, I would assess the size and scope of the building and determine how much time is needed for the job. Then, I would create a plan that outlines which areas need to be cleaned first and what tools are necessary for the job.

Once the plan is created, I would begin by prepping the area around the windows. This includes removing any debris or dirt from the frames and sills. After that, I would use a ladder to reach the higher windows and apply an appropriate cleaner to remove dirt and grime. Finally, I would use a squeegee to dry the surface and leave a streak-free finish.

Throughout the process, I would ensure that safety protocols are followed at all times. This includes wearing protective gear, using ladders properly, and avoiding slippery surfaces. By following these steps, I can guarantee a professional window cleaning job on any large building.”

21. Are there any health benefits to window cleaning?

Employers may ask this question to make sure you are aware of the physical demands of the job. They want to know that you can handle the work and will be able to do it safely. In your answer, explain how window cleaning is a physically demanding job. Explain how you stay healthy while doing the job.

Example: “Yes, there are many health benefits to window cleaning. Window cleaning can help improve your physical and mental wellbeing by providing an opportunity for exercise and fresh air. It also helps reduce stress levels as it is a repetitive task that requires focus and concentration. Furthermore, the act of cleaning windows can be meditative and calming, allowing you to clear your mind and relax. Finally, window cleaning increases natural light in a home or office, which has been proven to boost moods and productivity.

I believe my experience as a professional window cleaner makes me the perfect candidate for this job. I have extensive knowledge on how to safely clean windows without damaging them or putting myself at risk. I am confident that I can provide excellent service to customers while taking advantage of the health benefits associated with window cleaning.”

22. What kind of training have you had in safety procedures for working at heights?

Window cleaning often involves working at heights, so employers ask this question to make sure you have the necessary training and experience. In your answer, explain that you understand how to work safely at high levels. Share what kind of training you’ve had in this area and any certifications you may have.

Example: “I have had extensive training in safety procedures for working at heights. I completed a two-day course on the proper use of ladders, scaffolding, and other equipment used to access windows from elevated positions. I also learned how to properly secure my tools and materials while working at height, as well as techniques for safely maneuvering around obstacles such as air conditioning units or roof protrusions.

In addition, I am familiar with all relevant OSHA regulations related to window cleaning and take great care to ensure that I follow them at all times. Finally, I understand the importance of using appropriate personal protective equipment when working at height and always make sure to wear a harness and hard hat when necessary.”

23. Do you have any tips or tricks that make window cleaning easier or quicker?

Employers ask this question to see if you have any special skills or techniques that make your job easier. They want someone who can get the job done quickly and efficiently, so they may be looking for answers like “I use a squeegee with a long handle” or “I always clean windows from top to bottom.”

Example: “Yes, I do have some tips and tricks that make window cleaning easier and quicker.

The first tip is to use the right tools for the job. Having a squeegee with a good rubber blade along with a quality microfiber cloth will help you clean windows faster and more effectively. It’s also important to use the correct solution for each type of window. For example, using a vinegar-based cleaner on glass windows can leave streaks and smudges.

Another tip is to work in sections when cleaning windows. This helps ensure that no area is missed or overlooked. Also, it’s important to start from the top and work your way down. This prevents any dirt or debris from running down onto areas that have already been cleaned.

Lastly, it’s important to take your time and be thorough. Cleaning windows quickly but not thoroughly won’t get the job done properly. Taking the extra time to make sure all surfaces are spotless will result in better looking windows and happier customers.”

24. What type of insurance do you carry when performing window cleaning jobs?

Employers may ask this question to make sure you have the proper insurance coverage for your job. They want to know that if something happens while you’re working, you’ll be covered and they won’t need to cover any costs. Before your interview, find out what type of insurance the company offers its employees. If it’s not available, look into getting your own personal policy.

Example: “I carry general liability insurance when performing window cleaning jobs. This type of insurance covers me in the event that I cause damage to a client’s property while on the job. It also provides protection if someone is injured due to my negligence or carelessness. Having this insurance gives clients peace of mind knowing that they are protected from any potential losses or damages resulting from my work.

In addition, I have worker’s compensation insurance which covers any medical costs and lost wages should I become injured while working. This ensures that I am taken care of financially if something were to happen while on the job.”

25. Have you ever encountered a problem while window cleaning that you were unable to solve?

Employers ask this question to see how you respond to challenges. They want to know that you can think critically and find a solution to any problem that arises while working on their job site. In your answer, explain the situation, what steps you took to solve it and what the outcome was.

Example: “Yes, I have encountered a few problems while window cleaning that I was unable to solve. One of the most difficult issues I faced was when I had to clean windows on an extremely tall building. The challenge was finding a way to reach the higher windows safely and efficiently. After doing some research, I discovered a specialized platform that allowed me to access the higher windows with ease. This solution enabled me to complete the job quickly and effectively.”
