Your windows do more than frame the view—they control how much natural light fills your home and how your property looks from the street. When they’re covered in hard water spots, pollen, and grime, you’re living with dimmed rooms and a home that looks tired from the outside.
Professional window cleaning changes that immediately. You get crystal-clear glass that lets in maximum natural light, making every room brighter and more welcoming. Your home’s exterior looks sharp and well-maintained, the kind of place that catches attention for all the right reasons.
The difference isn’t just cosmetic. Clean windows can reduce your need for artificial lighting during the day and help you spot potential issues with frames, seals, or screens before they become expensive problems.
High Pro Power Washing Service Inc. has been serving Colesville and Montgomery County since 2019. We’re the locally owned company that understands exactly what Montgomery County’s weather does to your windows—from hard water mineral deposits to seasonal pollen buildup.
Our certified excellence on Yelp and NextDoor comes from over 200 five-star reviews, but more importantly, it comes from showing up when we say we will and delivering the results we promise. We use eco-friendly cleaning solutions that are safe for your plants, pets, and family while being tough enough to handle Maryland’s unique cleaning challenges.
You’re not just hiring window cleaners—you’re working with neighbors who live in this community and understand what homeowners in Colesville actually need.
We start with a free estimate where we assess your windows and discuss any specific concerns—hard water stains, screens that need attention, or tricky second-story access. No surprises, no pressure, just a clear understanding of what needs to be done.
On cleaning day, our trained technicians arrive with all necessary equipment and eco-friendly solutions. We protect your landscaping and outdoor furniture, then systematically clean each window inside and out. For exterior cleaning, we use professional-grade tools and pure water systems that eliminate streaking.
We don’t just clean the glass. Window sills, tracks, and screens get attention too because half-clean windows still look dirty. Before we leave, we do a final walkthrough with you to ensure every window meets our standards—and yours.

Every window cleaning service includes interior and exterior glass cleaning, screen cleaning and reinstallation, and thorough cleaning of sills and tracks. We remove hard water deposits that are common in Montgomery County using specialized solutions that won’t damage your glass or frames.
In Colesville, we see specific challenges that many homeowners don’t realize are affecting their windows. The mineral content in local water creates stubborn spots that regular cleaning can’t touch. Seasonal pollen from the area’s mature trees creates a film that dims natural light. Our process addresses these local conditions specifically.
We also include a satisfaction guarantee because we know what properly cleaned windows should look like. If you’re not completely satisfied with any aspect of our work, we’ll return to make it right at no additional cost.
Most Colesville homeowners benefit from professional window cleaning twice a year—typically spring and fall. However, your specific needs might be different based on your home’s exposure to trees, proximity to busy roads, and your personal preferences for natural light.
Spring cleaning removes winter buildup and prepares your windows for the season when you want maximum natural light. Fall cleaning removes summer’s pollen and prepares your windows for winter months when every bit of available light matters.
If your home is surrounded by mature trees or you’re particularly sensitive to how your windows look, quarterly cleaning might be worth considering. We can assess your specific situation during our free estimate and recommend a schedule that makes sense for your home and budget.
Yes, hard water stain removal is one of our specialties, and it’s particularly important in Montgomery County where mineral-rich water creates stubborn deposits on glass. These white, cloudy spots don’t come off with regular cleaning and actually get worse over time if not properly addressed.
We use industry-grade solutions specifically designed to break down calcium, lime, and other mineral deposits without damaging your windows or surrounding materials. The process is safe for your glass, frames, and landscaping while being effective enough to restore clarity to even heavily stained windows.
The key is addressing hard water stains before they become etched into the glass, which can happen with prolonged exposure. During our assessment, we’ll identify any windows with mineral buildup and explain exactly how we’ll restore them to crystal-clear condition.
Absolutely. We use only eco-friendly, biodegradable cleaning solutions that are safe for your family, pets, and landscaping. This isn’t just about being environmentally responsible—though that matters to us—it’s about protecting everything you care about around your home.
Our cleaning solutions are specifically formulated to be tough on dirt and grime while being gentle on everything else. They won’t harm your flower beds, won’t create runoff that damages your lawn, and won’t leave residues that could affect your family’s health.
We also take physical precautions during the cleaning process, covering plants when necessary and controlling water flow to minimize any impact on your landscaping. Many of our clients are surprised by how careful we are with their outdoor spaces—it’s just part of doing the job right.
For exterior-only window cleaning, you don’t need to be home as long as we have access to your property and any gates or areas where your windows are located. We can complete the outside cleaning, leave everything secure, and provide you with before-and-after photos of the work.
If you want interior windows cleaned—which we recommend for the best results—someone needs to be home to provide access. Interior cleaning makes a significant difference in how much light comes through your windows and how clear your view is from inside your home.
We’re flexible with scheduling and can work around your availability. Many clients prefer to be home for the first cleaning to see our process and discuss any specific concerns, then feel comfortable with exterior-only service for future cleanings.
Rain actually doesn’t make properly cleaned windows dirty—it’s the mineral deposits and contaminants already on the glass that create spots and streaks when mixed with water. When windows are professionally cleaned with the right techniques and solutions, rainwater sheets off cleanly without leaving marks.
If we clean your windows and it rains within 24 hours, we guarantee our work. If you see any spots or streaks that shouldn’t be there, we’ll return to address them at no charge. This rarely happens with proper cleaning techniques, but we stand behind every job we complete.
The key difference is in the cleaning process itself. Professional cleaning removes all the microscopic residues and films that cause water to bead up and leave spots. When your windows are truly clean, rain actually helps keep them looking good longer.
Window cleaning costs vary based on the number of windows, their size and accessibility, and whether you want interior and exterior cleaning or exterior only. Most Colesville homes with standard window configurations can expect to invest between $150-300 for complete interior and exterior cleaning.
We provide free, no-obligation estimates because every home is different. Factors like second-story windows, hard water stain removal, and the number of screens all affect pricing. During our estimate, we’ll give you exact pricing with no hidden fees or surprises.
New customers receive 15% off their first service, which makes it easy to experience our quality firsthand. We also offer flexible scheduling and can discuss service packages if you’re interested in regular maintenance throughout the year.
