Windows That Actually Stay Clean

You know the frustration. You spend your Saturday morning cleaning windows, and by the time you step back to admire your work, you’re staring at streaks, water spots, and somehow more smudges than when you started.

Professional window cleaning changes that completely. Your windows stay crystal clear for months, not days. Natural light floods your rooms without that dingy film you’ve gotten used to. From the street, your home looks sharp and well-maintained.

The difference isn’t just what you see – it’s what you don’t have to do. No more dragging out ladders, no more aching arms from scrubbing, no more buying cleaning products that promise the world and deliver disappointment.

Stephen Knolls Window Washing

We Actually Know What We're Doing

High Pro Power Washing Service Inc has been cleaning windows in Stephen Knolls and throughout Maryland for years. We’re not the guys who show up with a squeegee and hope for the best.

We use professional-grade equipment and techniques that most homeowners have never seen. Our team knows the difference between cleaning residential windows and commercial glass, understands how Maryland’s weather affects different types of glass, and can spot potential issues before they become expensive problems.

You’re not just getting clean windows – you’re getting the peace of mind that comes with working with people who take this seriously.

Window Cleaning Process

Here's Exactly What We Do

First, we assess your windows and identify any problem areas – hard water stains, paint specks, or built-up grime that needs special attention. We’re not rushing through this part because it determines everything that comes next.

Next comes the actual cleaning. We start with a thorough rinse to remove loose dirt and debris. Then we apply our cleaning solution, which is designed to break down the film and residue that regular household cleaners leave behind. The squeegee work comes last, and this is where experience shows – proper technique prevents streaks and ensures every inch gets cleaned.

For interior windows, we protect your floors and furniture, then clean both the glass and frames. We finish by checking our work in different lighting conditions because windows can look clean until the sun hits them at the right angle.

How often should I have my windows professionally cleaned?

Most Stephen Knolls homeowners benefit from professional window cleaning twice a year – spring and fall. Spring cleaning removes winter grime and prepares your windows for the bright summer months. Fall cleaning clears away pollen, dust, and debris before winter weather sets in. If you live near busy roads or have large trees close to your home, you might want quarterly cleaning. The frequency really depends on your specific situation and how much the appearance of your windows matters to you.
Light overcast conditions are actually ideal for window cleaning. The glass doesn’t dry too quickly, which gives us better control over the cleaning process and prevents streaking. We avoid cleaning during active rain or when heavy storms are imminent, but a little cloud cover works in our favor. If weather becomes an issue during your scheduled service, we’ll reschedule at no charge. We’d rather do the job right than rush through it because of weather conditions.
Yes, we can handle most hard water stains and paint specks that accumulate on windows over time. Hard water stains require special techniques and solutions that go beyond regular window cleaning. Paint specks need to be carefully scraped away without scratching the glass. These issues take extra time and attention, but they’re part of what separates professional window cleaning from DIY attempts. If stains are particularly severe or have been there for years, we’ll let you know upfront what’s realistic to expect.
We bring all our own professional equipment, cleaning solutions, and tools. We only need access to a water source at your property. Our equipment includes extension poles for high windows, professional squeegees, and cleaning solutions designed specifically for glass. We also bring drop cloths to protect your floors during interior cleaning. You don’t need to provide anything or prepare your windows in advance – we handle everything from start to finish.
A typical Stephen Knolls home with 15-20 windows takes about 2-3 hours for complete interior and exterior cleaning. Larger homes or properties with many windows can take longer. Homes with significant hard water staining or windows that haven’t been professionally cleaned in years require additional time. We don’t rush the process because proper window cleaning can’t be hurried. We’ll give you a realistic time estimate when we schedule your service based on your specific home and window situation.
If you’re not completely satisfied with our window cleaning, we’ll return to address any issues at no additional charge. Professional window cleaning should deliver streak-free, crystal-clear results that last for months. If we missed spots, left streaks, or didn’t meet your expectations in any way, just let us know within a few days of service. We stand behind our work because we know what properly cleaned windows should look like, and we won’t consider the job complete until you’re happy with the results.
