What is the best way to clean exterior windows?
For a streak-free finish, the best method is often a simple solution of dish soap, vinegar, and water applied with a squeegee. For tougher grime or hard-to-reach windows, professionals use water-fed pole systems. Some situations may even call for light pressure washing to remove stubborn buildup, but this requires a delicate touch to avoid damage. An experience pro can help you remove tough stains without harming your windows.
How often should you have your windows cleaned?
It’s a good idea to schedule exterior window cleaning at least twice a year. This regular maintenance prevents the buildup of dirt, pollen, and grime that can obstruct your view. It also protects the glass from etching, which can extend the lifespan of your windows.
How long does it take to clean exterior windows?
Typically, it will take a professional two to four hours to clean outside windows, but the total time depends on a few factors. For example:
The total number of windows on your home will have the biggest impact on the job timeline.
Windows on higher floors or those blocked by landscaping can take longer to access and clean safely.
Heavily soiled windows with hard water stains, grime, or paint overspray will require more time and effort.
Special window types, like multi-pane French doors or storm windows, often require more detailed cleaning.
Larger windows, such as picture windows or sliding glass doors, have more surface area and take longer to clean.
Remember: The timeline for your project will vary depending on many factors. Always ask your pro to provide an estimate.
Should I DIY or hire a pro to clean my windows?
Window cleaning can be a DIY project for some homeowners, but it's often a job best left to the pros. Here's why you might want to hire a pro for this task:
Pros often have the right safety equipment and experience to clean high or hard-to-reach windows, which helps prevent falls and injuries.
Most pros use specialized tools and purified water systems that leave a streak-free finish without the mineral spots tap water can cause.
It's a time-consuming chore, and hiring a pro frees up your weekend while ensuring the job is done right.
Pros can often spot underlying issues you might miss, like damaged window seals or frames, helping prevent future leaks or drafts.
In many cases, you’ll get a far better and longer-lasting result. Pros have the techniques to remove stubborn grime that most DIY methods can't tackle.
What questions should I ask professional window cleaners?
Before hiring an exterior window cleaning service, be sure to ask your pro these questions:
Are you licensed and insured?
How do you price your services, and can you provide a detailed estimate?
What cleaning solutions and methods do you use, and are they safe for my windows, siding, and landscaping?
What's included in a standard cleaning, and do you offer other exterior services like pressure washing?
Can you provide references or show examples of your previous work?
How long will the job take, and what is your availability?
Do you offer a satisfaction guarantee or have a policy for addressing any issues after the work is complete?
How do I prepare for exterior window cleaning?
Before your window cleaner arrives, take these steps to ensure a safe and efficient appointment:
Step 1: Clear the area around your windows. Move any outdoor furniture, potted plants, or decorations to give your pro easy access.
Step 2: Close and lock all windows and doors. This simple step prevents any water or cleaning solutions from accidentally getting inside your home.
Step 3: Secure your pets and inform your family. Keep pets indoors and let everyone in the house know when the window cleaners are expected to arrive.
Step 4: Ensure outside water access is available. Your pro will likely need to connect a hose to an outdoor spigot, so make sure it’s on and accessible.
Step 5: Point out any specific concerns. If you have any damaged screens, cracked panes, or particularly stubborn spots, let your pro know beforehand.
