Clean windows don’t just look good—they change how your home feels. More natural light means less need for artificial lighting during the day. Your rooms feel bigger, brighter, and more welcoming.
You get unobstructed views of your surroundings without streaks or water spots blocking the way. Plus, regular cleaning prevents permanent damage from hard water stains and environmental buildup that can actually etch your glass over time.
The difference is immediate. One day you’re squinting through grimy glass, the next you’re wondering why you waited so long to call professionals.
High Pro Power Washing has been serving Montgomery and Frederick Counties since 2019. We’re the locally owned company that homeowners call when they want the job done right the first time.
Our technicians know Marymount’s unique challenges—from spring pollen that coats everything to the hard water that leaves those stubborn spots. We use eco-friendly solutions that are safe for your family, pets, and landscaping while delivering the streak-free results you expect.
We’re certified on Yelp and Nextdoor because we show up on time, do what we promise, and stand behind our work with a satisfaction guarantee.
First, we assess your windows and determine the best cleaning method for your specific situation. Every home is different, and we adjust our approach accordingly.
We start by removing screens, labeling them, and setting them aside for cleaning. One technician works inside with protective booties and drop cloths, while another handles the exterior using either water-fed poles or traditional methods depending on your windows’ height and accessibility.
We clean the glass, frames, sills, and tracks thoroughly. Screens get the same attention before being reinstalled in their proper locations. The whole process typically takes half a day for an average home, and we don’t consider the job finished until you’re completely satisfied with the results.

Every window cleaning includes interior and exterior glass, frames, sills, and tracks. Screen cleaning is always included at no extra charge—we remove, clean, and reinstall every screen.
In Marymount, we see a lot of homes with challenging access points and varying window types. Our equipment handles everything from ground-level windows to second-story installations safely. We use specialized tools and eco-friendly cleaning solutions that work effectively on Maryland’s hard water stains and environmental buildup.
We also clean mirrors, glass doors, and can handle skylights or other specialty glass features while we’re there. Our goal is to leave every piece of glass in your home spotless and streak-free.
Most Marymount homeowners benefit from professional window cleaning 2-3 times per year, typically in spring and fall. However, if your home faces busy roads or you have a lot of trees nearby, you might want quarterly service.
Spring cleaning removes winter buildup and pollen residue that’s heavy in our area. Fall cleaning prepares your windows for winter and removes summer’s accumulated grime. Some homeowners add a mid-summer cleaning if they entertain frequently or simply want to maintain that crystal-clear view year-round.
The frequency really depends on your specific situation and preferences. We can recommend a schedule during your free estimate based on your home’s location and exposure.
Absolutely. All our cleaning solutions are eco-friendly and completely safe for your family, pets, and landscaping. We specifically chose these products because many Marymount families have children and pets who spend time in yards where traditional harsh chemicals could pose risks.
Our biodegradable solutions effectively remove dirt, grime, and hard water stains without leaving harmful residues. They’re tough on buildup but gentle on everything else. We’re also mindful about water usage and runoff to protect your plants and lawn.
You don’t have to worry about keeping pets inside during our service or waiting for chemicals to dissipate. Our eco-friendly approach means your family can enjoy the results immediately without any safety concerns.
Honestly, very little. We handle most of the preparation ourselves, including carefully moving furniture, removing and reinstalling drapes or blinds, and protecting your floors with drop cloths when necessary.
The main thing is making sure we can access your windows from both inside and outside. Move any fragile items from windowsills, and let us know if any windows have special considerations or if certain rooms are off-limits during specific times.
We’ll need access to your home’s interior, but you can go about your day normally. Many of our customers leave for work while we’re cleaning and come home to sparkling windows. We just ask that you do a final walkthrough with us when we’re finished to ensure everything meets your expectations.
Yes, hard water stains are one of our specialties, and they’re particularly common in the Marymount area. Our specialized cleaning solutions and techniques are specifically designed to break down mineral deposits that cause those cloudy, spotted appearances.
For severe buildup, we may need to use slightly more aggressive methods, but we always start with the gentlest approach that will be effective. Most hard water stains come off completely with our standard process, restoring your windows to crystal clarity.
The key is addressing them before they become permanently etched into the glass. Regular professional cleaning prevents hard water deposits from building up to the point where they cause permanent damage. If you’ve been putting off window cleaning because of stubborn stains, we can likely get them looking like new again.
Safety is our top priority, and we have multiple methods for reaching upper-story windows safely. For many second-story windows, we use water-fed pole systems that allow us to clean effectively from ground level, eliminating ladder risks entirely.
When ladders are necessary, our technicians are trained in proper ladder safety and use professional-grade equipment. We also use ladder mitts to protect your home’s exterior from dings or marks during the process.
Our experience with Montgomery County homes means we’re familiar with various architectural styles and access challenges. We assess each situation carefully and choose the safest, most effective method for your specific windows. You never have to worry about unsafe practices or potential damage to your property.
We guarantee your satisfaction, period. If any aspect of our window cleaning doesn’t meet your expectations, we’ll return to fix it at no additional charge. We don’t consider the job complete until you’re completely happy with the results.
This satisfaction guarantee is backed by our reputation in the community and our certifications on platforms like Yelp and Nextdoor. We’ve built our business on referrals and repeat customers, so your satisfaction directly impacts our success.
Most issues are minor touch-ups that we can address immediately during the final walkthrough. But whether it’s a missed spot, a streak, or any other concern, we’ll make it right. Our goal is for you to be so pleased with the results that you’ll call us again and recommend us to your neighbors.
