You know the difference between windows that look “better” and windows that are actually clean. We deliver the latter. No streaks running down the glass when it rains. No film that makes everything look hazy. No water spots that show up the minute the sun hits them.
Clean windows let in more natural light, which means your home feels brighter and more welcoming. Your view isn’t distorted by buildup and grime. When guests pull up to your house, they see a property that’s clearly well-maintained.
Most importantly, you don’t have to risk your safety climbing ladders or spend your weekend fighting with squeegees that leave more streaks than they remove. Professional window cleaning means you get professional results without any of the work or worry.
High Pro Power Washing Service Inc has been handling exterior cleaning in Montgomery and Frederick Counties since 2019. We’re the local company that understands exactly what Maryland weather does to windows.
The humidity that creates water spots. The pollen that sticks to everything in spring. The way our climate can make clean windows look dirty again in what feels like days. We’ve built our window cleaning process specifically around these challenges.
We’re fully licensed and insured, which matters when someone’s working around your property with ladders and equipment. Our eco-friendly cleaning solutions are safe for your family, pets, and landscaping. Every job comes with our satisfaction guarantee because we stand behind our work.
We start with an assessment of your windows to identify any problem areas—hard water stains, paint overspray, or buildup that needs special attention. No surprises, no “oh, that’ll cost extra” moments after we start.
First, we thoroughly rinse your windows to remove loose dirt and debris. Then we apply our cleaning solution, which is formulated specifically to cut through the film and grime that build up on windows in Maryland’s climate. We use professional squeegees and techniques that eliminate streaking—not the hardware store squeegee that leaves lines everywhere.
For windows with screens, we remove and clean those separately. Screens get surprisingly dirty and can make even clean windows look dingy. We finish with a detailed inspection to catch any spots we might have missed. You get windows that are actually clean, not just “better than they were.”

Every window cleaning service includes interior and exterior cleaning of all accessible windows, screen removal and cleaning, and sill wiping. We bring our own water and equipment, so you don’t need to worry about providing anything. We handle the safety aspects—ladders, reaching second-story windows, all the stuff that makes DIY window cleaning risky.
In Westleigh, we see a lot of homes with large windows that take advantage of the area’s natural beauty. These windows deserve professional care that maintains their clarity without risking damage. Our water is filtered to prevent mineral deposits, which is especially important in areas with hard water.
We also carry backup equipment in case something breaks during the job, so weather and equipment issues don’t leave your job half-finished. Most single-family homes in Westleigh take 2-4 hours depending on the number of windows, their condition, and accessibility.
Most Westleigh homeowners benefit from professional window cleaning twice a year—spring and fall. Spring cleaning removes winter grime and prepares for the high-visibility months when you’re entertaining and spending more time outdoors. Fall cleaning clears away summer buildup before winter weather sets in.
If you live near busy roads or have large trees that create more debris, quarterly cleaning might make sense. The key is consistency—regular professional cleaning prevents buildup that becomes harder and more expensive to remove later. It’s much easier to maintain clean windows than to restore neglected ones.
The biggest difference is in the equipment and technique. We use professional-grade squeegees, filtered water, and cleaning solutions specifically formulated for Maryland’s climate challenges. Hardware store squeegees and regular tap water often leave streaks and water spots.
Beyond the tools, there’s the safety aspect. Reaching second-story windows safely requires proper ladders and experience. We’re fully licensed and insured for this work. We also know how to handle different types of windows—some require gentle cleaning to avoid damage, while others can handle more aggressive techniques.
Most importantly, we know what “actually clean” looks like versus “better than it was.” When we’re done, your windows will be streak-free and stay cleaner longer.
Cloudy days are actually ideal for window cleaning. Direct sunlight can cause cleaning solutions to dry too quickly, leading to streaks. We can work in most weather conditions, but we’ll reschedule if there’s active rain or high winds that would affect safety or results.
We monitor weather forecasts carefully and will contact you if conditions aren’t suitable for quality work. Maryland weather can be unpredictable, so we build flexibility into our scheduling. If we need to reschedule due to weather, we’ll work with you to find the next available time that works for both of us.
Our goal is always to deliver the best possible results, which means working in conditions that allow us to do our best work.
Yes, we use eco-friendly cleaning solutions that are safe for children, pets, and your landscaping. Our products are specifically chosen to be effective against Maryland’s specific challenges—humidity buildup, pollen, and environmental film—while being environmentally responsible.
We’re careful about runoff around your plants and lawn. Our solutions won’t harm your landscaping or leave residue that could be problematic for kids or pets playing in the yard. This is especially important for families in Westleigh who spend a lot of time in their outdoor spaces.
We can provide information about specific products if you have particular sensitivities or concerns. Our approach has always been that effective cleaning shouldn’t come at the expense of your family’s safety or your property’s health.
Very little preparation is required on your part. We need access to the interior of your home to clean the inside of windows, but you can go about your day as normal. We’ll carefully move any furniture or window treatments that need to be moved and put everything back when we’re done.
If you have any particularly fragile items on windowsills, you might want to move those beforehand, but we’re experienced in working around your belongings. We bring drop cloths to protect your floors and furniture.
The main thing we need is access to a water spigot, though we bring our own filtered water for the final cleaning. Clear communication about any special concerns or access issues helps us work more efficiently and ensures you’re completely satisfied with the service.
Window cleaning costs depend on several factors: the number of windows, their condition, accessibility, and whether you need interior and exterior cleaning. Most single-family homes in Westleigh range from $150 to $400 for complete interior and exterior service.
Houses with many windows, second stories, or windows that haven’t been professionally cleaned in years will be on the higher end of that range. We provide free estimates so you know exactly what to expect before we start work. There are no surprise charges or hidden fees.
We also offer a 15% discount for first-time customers and can set up regular maintenance schedules that often provide better value than one-time cleanings. The investment in professional cleaning typically pays for itself in the time you save and the superior results you get compared to DIY efforts.
