What’s Included in Professional Window Cleaning?
Updated: Sep 29
If you’ve never hired a professional window cleaner before, you may be wondering what you’re actually paying for. Is it simply someone spraying the glass and wiping it down?
Professional window cleaning involves much more than that.
At Window Washing Pros, we believe great window cleaning is about more than making the glass look clean. It’s about taking care of the entire window and delivering a great customer experience from start to finish.
Here’s what homeowners can typically expect from a professional window cleaning service.

1. Professional Cleaning of the Glass
The most obvious part of window cleaning is, of course, the glass.
Professional window cleaners use specialized tools and techniques to remove dirt, pollen, fingerprints, water spots, and other buildup without leaving behind streaks or residue.
Depending on the type and condition of your windows, this may include traditional squeegee cleaning or purified-water systems and water-fed poles for exterior glass.
The goal is simple: clean, clear glass that you can actually see through.
2. Window Frames, Sills and Tracks
One of the biggest differences between a basic window cleaning and a more thorough professional cleaning is what happens around the glass.
Dirt and debris can collect in:
Window tracks
Frames
Sills
Corners
Sliding channels
These areas can easily be overlooked during routine household cleaning.
A professional window cleaning service may include cleaning these areas as part of a full-service window cleaning. At Window Washing Pros, our full interior and exterior cleaning includes the tracks, frames, and sills so your windows look clean from top to bottom.
3. Screen Cleaning
Window screens collect an impressive amount of dust, pollen, bugs, and outdoor debris.
Even if your glass is perfectly clean, dirty screens can make your windows look hazy.
Professional screen cleaning removes the buildup that accumulates over time and helps your screens look fresh again.
Depending on the service, screens may be cleaned by hand or with specialized screen-cleaning equipment.
4. Interior Window Cleaning
For homeowners who choose interior and exterior window cleaning, the process also includes cleaning the inside surface of the glass.
This is especially helpful for removing:
Fingerprints
Dust
Pet nose prints
Cooking residue
Smudges
General household buildup
Professional cleaners also take care to protect your floors, furniture, and other areas around the windows while they work.
5. Exterior Window Cleaning
Exterior windows are exposed to everything the outdoors has to offer.
Over time, they can collect:
Pollen
Dirt
Spider webs
Bird droppings
Dust
Mineral deposits
Environmental buildup
Professional exterior window cleaning equipment allows technicians to safely reach many windows that would otherwise be difficult or dangerous for a homeowner to clean.
For taller homes, water-fed poles can allow technicians to clean exterior glass from the ground while using purified water to help minimize spotting.
6. Spotting Potential Problems
Another benefit of having your windows professionally cleaned is that a technician gets a close look at the condition of your windows.
During a cleaning, a professional may notice things such as damaged screens, deteriorating seals, hard-water staining, or other issues that may otherwise go unnoticed.
While window cleaning doesn't replace a professional window inspection, having someone regularly working with your windows can help you become aware of problems earlier.
7. Hard-Water and Mineral Deposits
Not every window can be cleaned with a standard window-washing process.
If sprinklers, irrigation, rainwater, or other sources repeatedly deposit minerals onto the glass, those deposits can eventually become difficult to remove.
This is particularly common in areas around Lake Norman and throughout North Carolina.
Depending on the severity, specialized hard-water removal may be necessary to restore the appearance of the glass.
8. Professional Equipment and Technique
One of the biggest advantages of hiring a professional is the equipment they bring with them.
Professional window cleaners may use:
Professional squeegees
Specialized cleaning solutions
Water-fed poles
Purified or deionized water
Screen-cleaning equipment
Extension poles
Ladders and other access equipment
