Our Window Cleaning Process

Simple Process, Professional Results Every Time

First, we assess your windows and identify any problem areas like hard water stains or built-up grime. This isn’t a one-size-fits-all approach – different windows need different treatment.

We start with a thorough rinse to remove loose dirt and debris. Then we apply professional-grade cleaning solutions that break down stubborn residue without damaging your glass or window frames. Our squeegee technique eliminates streaks and water spots that plague DIY cleaning attempts.

For exterior window cleaning, we handle all the ladder work and safety concerns. You don’t have to worry about anything except enjoying the results. We clean up after ourselves and do a final inspection to make sure every window meets our standards before we consider the job complete.

Residential Window Cleaning Services

What's Included In Every Service Call

Every residential window cleaning service includes both interior and exterior glass cleaning, plus cleaning of window sills and frames. We remove screens when necessary and clean those too – because what’s the point of clean windows if you’re looking through dirty screens?

We handle ground-level windows and upper-story windows with equal attention to detail. Our equipment reaches second and third-story windows safely, so you get consistent results on every piece of glass. Hard water stains and mineral deposits get special treatment with appropriate solutions.

Stronghold’s climate means your windows face unique challenges from seasonal pollen, road salt, and humidity. We adjust our cleaning methods based on what your specific windows are dealing with. The result is glass that stays cleaner longer and looks professionally maintained year-round.

How often should I have my windows professionally cleaned?

Most Stronghold homeowners benefit from professional window cleaning twice a year – typically spring and fall. Spring cleaning removes winter salt residue and prepares for pollen season, while fall cleaning handles summer buildup and prepares windows for winter weather. Commercial properties often need quarterly cleaning due to higher traffic and environmental exposure. If you’re near busy roads or have hard water issues, you might want to consider more frequent service. The good news is that professionally cleaned windows stay cleaner longer than DIY attempts, so the investment pays off in extended time between cleanings.
Light overcast conditions are actually ideal for window cleaning because direct sunlight can cause cleaning solutions to dry too quickly, leading to streaks. We’ll work in light drizzle, but we reschedule for heavy rain or storms for safety and quality reasons. If weather changes during your appointment, we’ll either finish up quickly or reschedule at no charge. Maryland weather can be unpredictable, so we build flexibility into our scheduling. The key is that we never compromise on results just to stick to a schedule – you’re paying for quality work, and that’s what you’ll get.
Yes, but it depends on how long they’ve been building up. Fresh mineral deposits and most hard water stains come off with proper solutions and techniques. Severe buildup that’s been ignored for years might require multiple treatments or specialized approaches. We’ll assess your windows during the initial visit and let you know what’s realistic. Some extremely old etching might be permanent, but most homeowners are surprised at what professional-grade treatments can accomplish. The important thing is addressing hard water issues regularly rather than letting them build up to the point where they damage the glass permanently.
We use eco-friendly, biodegradable cleaning solutions that won’t harm your landscaping or pose risks to pets and family members. Professional window cleaning solutions are actually much gentler than many household cleaners people use for DIY cleaning. We do rinse thoroughly to remove any residue, and we’re careful about overspray near sensitive plants. If you have specific concerns about particular plants or pets with sensitivities, just let us know when scheduling. Most of our solutions are similar to what you’d find in environmentally conscious household cleaners, just more effective at removing the specific residues that build up on glass.
Absolutely. Multi-story window cleaning is where professional service really makes sense – it’s safer, faster, and gets better results than trying to handle it yourself. We have the proper ladders, safety equipment, and insurance coverage for upper-story work. Many Stronghold homes have windows that are difficult or dangerous to reach, and that’s exactly what we’re equipped to handle. We take safety seriously, both for our team and your property. Upper-story windows often get neglected because they’re hard to reach, but they’re just as visible from the street and just as important for natural light inside your home.
The biggest differences are streak elimination, longevity, and safety. Professional squeegee techniques and solution ratios eliminate the streaking that frustrates most DIY attempts. Our cleaning solutions also include treatments that help windows stay cleaner longer by reducing static buildup that attracts dust and pollen. We can safely reach and properly clean upper-story windows that homeowners often skip or struggle with. Professional cleaning also removes residues that household cleaners leave behind – residues that actually attract dirt faster. Most customers notice their windows look cleaner longer after professional service compared to their own cleaning attempts, making the investment worthwhile for both results and time savings.
