Professional window cleaning that saves your time and keeps you safely on the ground.
Hear from Our Customers
You know that feeling when you finally get your windows clean and the whole house looks different? More light floods in. Your view is crystal clear. The whole place feels brighter and more welcoming.
That’s what happens when windows are actually clean—not just wiped down with paper towels and glass cleaner, but professionally cleaned with the right equipment and techniques. No streaks. No spots. No water marks that show up the minute the sun hits them.
Your neighbors notice. Your family notices. And honestly, you notice it every single day when you look outside. Clean windows make your entire property look well-maintained and cared for, which matters whether you’re planning to sell or just want to enjoy where you live.
High Pro Power Washing Service Inc has been serving Discovery and the greater Montgomery County area with professional cleaning services that homeowners can count on. We’re fully licensed and insured because this is our business, not a side hustle.
Window cleaning might look simple, but there’s a difference between someone with a squeegee and someone who understands the right techniques, solutions, and equipment to get results that last. We’ve invested in professional-grade tools and training because half-clean windows are worse than dirty ones.
You’ll work with the same reliable team every time. We show up when we say we will, we clean up after ourselves, and we stand behind our work.
First, we assess your property and identify any challenges—second-story windows, delicate landscaping, or screens that need special attention. We come prepared with the right equipment for your specific situation.
We start by removing screens and giving them a thorough cleaning. Then we pre-treat the glass to loosen dirt, pollen, and any stubborn spots that have built up over time. This step makes all the difference in getting truly clean results.
The actual cleaning involves professional-grade solutions and squeegee techniques that eliminate streaks and water spots. We clean both sides of every window—interior and exterior—and we detail the frames and sills. Before we leave, we do a final inspection to make sure everything meets our standards. You get windows that stay cleaner longer and look better than anything you could achieve with store-bought supplies.
Ready to get started?
Every window cleaning service includes interior and exterior glass cleaning, screen removal and cleaning, and frame and sill detailing. We bring our own water, professional cleaning solutions, and all the equipment needed to reach every window safely.
We handle the tricky stuff—second-story windows, windows over landscaping, and those hard-to-reach spots that most people skip. Our cleaning solutions are safe for your plants and won’t leave residue that attracts dirt faster.
You can schedule one-time cleanings or set up regular maintenance. Most Discovery homeowners find that quarterly cleaning keeps their windows looking great year-round, especially with Maryland’s pollen seasons and weather patterns. We’ll work around your schedule and send reminders when it’s time for your next cleaning.
