Windows That Actually Stay Clean

You know that frustration when you spend your Saturday cleaning windows only to see streaks and spots the moment sunlight hits them. Or worse, you get them looking decent from inside, but the outside still looks like it hasn’t been touched in months.

Professional window cleaning changes that completely. Your windows become something you actually notice in a good way. Natural light floods your rooms without that dingy filter. Your home looks sharp from the curb. You stop avoiding certain rooms because the view is embarrassing.

The difference isn’t just in how they look right after we’re done. It’s in how long they stay looking good. Professional techniques and commercial-grade equipment mean your windows resist dirt and water spots longer. You’re not back to square one in two weeks.

Glen Hills Window Cleaning Experts

We Actually Know Glass

High Pro Power Washing Service Inc has been cleaning windows throughout Glen Hills and the greater Maryland area for years. We’ve seen every type of window, every kind of buildup, and every challenge that Maryland weather throws at glass.

We’re not the guys who show up with a squeegee and hope for the best. Our technicians understand different glass types, the right cleaning solutions for various situations, and how to handle everything from standard residential windows to custom installations.

Most importantly, we show up when we say we will. You’re not chasing us down or wondering if we’re coming. We treat your property like it matters because it does.

Window Cleaning Process

Simple Process, Professional Results

We start with a quick assessment of your windows – what type of glass, what kind of buildup we’re dealing with, and any specific challenges like hard water stains or paint overspray. This isn’t about upselling you. It’s about using the right approach from the start.

Next comes the actual cleaning. We use professional-grade solutions that break down dirt and grime without damaging your glass or frames. Our equipment includes commercial squeegees, water-fed pole systems for high windows, and specialized tools for different window types.

The final step is detailing – catching any missed spots, cleaning the sills and frames, and making sure everything looks right before we leave. You’ll see the difference immediately, and more importantly, you’ll see it lasting longer than any DIY job you’ve tried.

What You Actually Get

Our window cleaning service covers both interior and exterior surfaces. We handle the obvious stuff – the glass itself – but also clean the window sills, frames, and screens. It’s the complete package, not just a quick squeegee job.

We work around your schedule, not the other way around. Most Glen Hills residential jobs take 2-4 hours depending on the size of your home and number of windows. We’ll give you a realistic timeframe upfront, and we stick to it.

For homes with multiple stories or hard-to-reach windows, we bring the right equipment to do the job safely. No shortcuts, no “good enough” results on the difficult windows. Every window gets the same attention whether it’s a ground-floor picture window or a third-story bathroom window.

How often should I have my windows professionally cleaned?

Most Glen Hills homeowners benefit from professional window cleaning twice a year – typically spring and fall. Maryland’s pollen seasons and winter weather create buildup that’s tough to handle with regular maintenance. If you’re near busy roads or have large trees close to your house, you might want quarterly cleaning. Commercial properties usually need monthly or bi-monthly service depending on foot traffic and environmental factors. The key is consistency – regular professional cleaning prevents the kind of buildup that becomes difficult and expensive to remove.
The biggest difference is in the equipment and technique. We use commercial-grade squeegees, specialized cleaning solutions, and water-fed pole systems that reach high windows safely. We know how to clean without leaving streaks, how to handle different types of glass, and how to deal with stubborn stains like hard water spots or paint overspray. DIY cleaning usually results in streaks, missed spots, and doesn’t last as long. Plus, there’s the safety factor – we have the right equipment and insurance to handle multi-story windows that are dangerous for homeowners to attempt.
We clean windows year-round, but we’re smart about timing. We don’t clean in freezing temperatures, during storms, or when conditions would prevent good results. Winter cleaning can actually be beneficial because there’s less pollen and dust, so the results last longer. We’ll reschedule if weather conditions aren’t right rather than doing a poor job. Most customers prefer spring and fall cleaning anyway, which works well with Maryland’s climate. If you need emergency cleaning for a special event or showing, we’ll work with you to find the best possible timing.
Yes, we use eco-friendly cleaning solutions that won’t harm your landscaping, pets, or family. Our professional-grade cleaners are biodegradable and designed to be safe around plants and animals. We’re also careful about runoff – we don’t just spray and hope for the best. If you have sensitive plants directly under windows, we’ll take extra precautions like covering them or using minimal solution in those areas. Many of our solutions are actually safer than typical household glass cleaners because they’re designed for professional use where safety regulations are stricter.
If you’re not happy with our work, we’ll come back and fix it at no charge. This rarely happens because we check our work before leaving, but if you notice something we missed or if you’re not satisfied with the results, just call us within 24 hours. We’ll return to address any issues. Our goal is windows that you’re actually proud of, not just “good enough” results. We’ve been doing this long enough to know what quality looks like, and we stand behind our work. Most customers are surprised by how much better their windows look compared to what they expected.
Window cleaning costs depend on the number of windows, their size, accessibility, and current condition. Most Glen Hills homes with 15-25 windows run between $150-300 for a complete interior and exterior cleaning. Larger homes or those with difficult access windows cost more. We provide upfront pricing after a quick assessment – no surprises or hidden fees. Regular customers often get better rates because the windows are easier to maintain when they’re cleaned consistently. The investment usually pays for itself in time saved and better results compared to DIY attempts, plus you avoid the cost and safety risks of buying ladders and professional equipment.
