When your windows are properly cleaned, you’re not just improving curb appeal—you’re protecting your investment. Clean windows let more natural light into your home, making spaces feel larger and more welcoming. You’ll notice the difference immediately: no streaks, no water spots, just crystal-clear glass that stays cleaner longer.
Most homeowners are surprised by how much brighter their rooms feel after professional cleaning. That’s because DIY methods often leave behind residue that dulls the glass over time. Our process removes everything—pollen, hard water deposits, road dust, and the buildup that accumulates from Maryland’s changing seasons.
You also get peace of mind knowing the job is done safely. No more climbing ladders or struggling with second-story windows. We handle the safety concerns and have the right equipment to reach every window without putting anyone at risk.
High Pro Power Washing Service Inc has been serving Mountaindale and Frederick County since 2019. We understand Maryland weather—the heavy pollen seasons, the hard water issues, the way our humid summers create stubborn buildup on glass.
We’re not the company that shows up and hopes for the best. We bring professional-grade equipment, proven methods, and the attention to detail that makes the difference. Our team is fully licensed, bonded, and insured, with over 200 five-star reviews on Yelp and NextDoor.
What sets us apart is our approach to each property. We treat your home like it’s our own, using eco-friendly cleaning solutions that are safe for your family, pets, and landscaping. We’ve built our reputation in Mountaindale by doing what we say we’ll do, when we say we’ll do it.
First, we assess your windows and remove any screens that need separate cleaning. We start with a thorough rinse to remove loose dirt and debris, then apply our professional-grade cleaning solution that breaks down grime, hard water spots, and built-up residue without damaging glass or frames.
The actual cleaning involves proper squeegee technique—not just dragging a blade across the glass, but using overlapping strokes that eliminate streaks and water spots. We clean both sides of each window, paying special attention to corners and edges where dirt typically accumulates.
Finally, we detail the window frames and sills, replace clean screens, and do a final inspection to make sure everything meets our standards. We bring all the equipment needed, including professional squeegees, extension poles for high windows, and drop cloths to protect your floors and landscaping.

Every window cleaning service includes interior and exterior glass cleaning, screen cleaning and replacement, frame and sill detailing, and our satisfaction guarantee. We use eco-friendly cleaning solutions specifically chosen to handle Maryland’s local challenges—seasonal pollen, road dust, and hard water deposits.
For Mountaindale homeowners, we understand the specific conditions that affect your windows. Spring pollen removal requires different techniques than winter salt residue. Summer humidity buildup needs different treatment than fall leaf debris. We adjust our approach based on what your windows actually need.
Safety is handled professionally. We have the proper equipment and training to clean second-story windows without putting anyone at risk. Many homeowners try to clean their own high windows and either can’t reach them properly or put themselves in danger. We eliminate those concerns while delivering results you simply can’t achieve with garden hose methods.
Most Mountaindale homeowners benefit from professional window cleaning twice per year—typically spring and fall. Spring cleaning removes winter grime and prepares windows for the brighter months ahead, while fall cleaning handles summer dust and pollen before winter weather arrives.
However, your specific needs depend on several factors. Homes near busy roads or construction areas may need quarterly cleaning due to increased dust and debris. Properties with lots of trees often require more frequent service because of sap, bird droppings, and organic buildup.
Many homeowners also request service in late spring after heavy pollen season ends, usually around mid-May. This timing helps maintain clear views during the peak outdoor months when you want maximum natural light in your home.
Yes, we clean windows at any height safely and effectively. We have professional-grade extension poles, ladders, and safety equipment specifically designed for high window cleaning. Our team is trained in proper safety procedures and we’re fully insured for this type of work.
Many homeowners try to clean their own second-story windows and either can’t reach them properly or put themselves at risk. We handle the safety concerns and have the right tools to get streak-free results on high windows that you simply can’t achieve from the ground.
Safety isn’t just about having the right equipment—it’s about knowing how to use it properly. Our technicians are experienced in working at heights and follow strict safety protocols to protect both your property and themselves during every job.
Yes, we can remove most hard water stains and mineral deposits using specialized cleaning solutions and techniques. Maryland’s hard water creates stubborn white spots and cloudy buildup that regular cleaning can’t touch. These spots form when mineral-rich water evaporates on glass, leaving behind calcium and magnesium deposits.
We use professional-grade products specifically designed to dissolve these mineral deposits without damaging the glass. Our process breaks down the buildup that accumulates over time, restoring your windows to like-new clarity.
However, some extremely old or severe staining may be permanent if it’s etched into the glass surface. During our initial assessment, we’ll let you know what’s removable and what might require glass replacement. In most cases, we can restore your windows to crystal-clear condition.
Absolutely. We use environmentally friendly and biodegradable cleaning solutions that are safe for your home, garden, and surrounding landscape. Our products are carefully selected to remove dirt, mold, and grime effectively without causing harm to plants, pets, or property surfaces.
We take extra care during the application process to protect sensitive areas like flower beds and shrubs. Our eco-friendly approach means you don’t have to worry about runoff affecting your landscaping or creating unsafe conditions for children and pets who use your outdoor spaces.
This commitment to safe cleaning methods is part of what sets us apart. You get professional results without compromising the health of your family, pets, or the environment around your home.
Spring and fall are ideal times for window cleaning in Maryland. Spring cleaning removes winter salt residue, grime, and prepares your windows for the bright summer months ahead. Fall cleaning removes summer buildup and ensures maximum natural light during darker winter months.
Many Mountaindale homeowners also request service in late spring after heavy pollen season ends, usually around mid-May. Maryland’s pollen seasons peak in April, June, and September, so timing your cleaning after these periods helps maintain clear views longer.
Winter cleaning is possible during mild weather periods, but results may not last as long due to ongoing weather conditions. The key is working with local weather patterns rather than against them to get the best value from your professional cleaning investment.
Yes, we guarantee your complete satisfaction with every window cleaning service. If you’re not happy with any aspect of our work, we’ll return to address the issue at no additional charge. This covers streaking, missed spots, or any areas that don’t meet our quality standards.
Our satisfaction guarantee reflects our confidence in our methods and our commitment to getting it right. We’re not satisfied until you can see the difference our professional cleaning makes. It’s that simple.
We stand behind every job because we know what proper window cleaning should look like. When you choose High Pro Power Washing Service Inc, you’re choosing a company that takes responsibility for delivering the results you expect.
