Professional Window Cleaning in Princeton, NJ & the Delaware Valley
Crystal-clear windows for homes and businesses. Interior, exterior, screens, tracks, and frames.
Window Cleaning That Makes a Difference
Clean windows are often overlooked, but they make a significant difference in the appearance and atmosphere of any property. They allow more natural light in, improve comfort, and instantly boost curb appeal.
Our professional window cleaning uses the latest techniques and equipment to remove dirt, grime, and streaks, leaving your windows sparkling clean. Whether your home has standard windows, skylights, French doors, or hard-to-reach glass, our team delivers spotless results every time.
Every window cleaning includes interior and exterior glass, screens, tracks, and frames. We also clean storm windows, transoms, and sidelights when present.
Professional vs. DIY Window Cleaning
Most people only clean the glass surface with store-bought spray and paper towels. A professional cleaning covers both sides of every window plus screens, tracks, sills, and frames. We use professional squeegees and solutions that leave zero streaks and no residue, unlike household glass cleaners that leave a film behind.
Why Clean Windows Matter
Dirty glass blocks more sunlight than you would expect. After a professional cleaning, rooms feel brighter and more open right away. Regular cleaning also extends the lifespan of your windows by preventing hard water minerals and oxidation from etching into the glass over time.
Interior and Exterior: Both Sides Count
Exterior glass takes a beating from rain, pollen, tree sap, and road dust. Interior glass collects fingerprints, cooking grease, and dust. We clean both sides every time because doing only the outside still leaves you looking through a hazy interior pane. When we are inside your home, we lay down protective covers and treat your space with care.
Hard Water Stain Removal
Hard water stains are common across central New Jersey and Bucks County, especially on homes with sprinkler systems. Those white, cloudy mineral deposits will not come off with regular glass cleaner. Our standard cleaning handles light buildup, and for heavy staining we offer a glass restoration treatment that dissolves and polishes out the deposits completely.

Common Questions About Window Cleaning
How much does professional window cleaning cost?
For most homes across NJ and PA, professional window cleaning typically runs $250 to $750+. The price depends on how many windows you have, their size, and accessibility. A 15-window ranch costs less than a 40-window colonial with skylights. We include screens, tracks, and frames in every job and give you a clear, upfront quote with no surprises. Reach out for a free estimate.
Is professional window cleaning worth it?
Yes. Professional squeegees leave zero streaks and no residue. We detail every part of the window, not just the glass, so your windows function better and last longer. It saves you a full weekend of DIY work, eliminates the safety risk of working on ladders, and protects your glass from long-term damage caused by hard water deposits and oxidation.
How often should windows be cleaned?
For most homes in the Princeton area, twice a year is ideal. A spring cleaning removes pollen and winter buildup, and a fall cleaning gets your windows clear before the holidays. Homes near busy roads, construction, or heavy tree cover benefit from quarterly cleanings. Commercial storefronts often benefit from monthly service.
What is the difference between window washing and window cleaning?
The terms are used interchangeably. A professional window cleaning includes much more than just washing the glass. We detail frames, clean tracks, wash screens, and wipe sills. If you are comparing quotes from companies in central New Jersey and Bucks County, always ask what is included, because the scope of work can vary significantly.
How much does it cost to clean windows on a 1,500 sq ft house?
A 1,500-square-foot home typically has 12 to 20 windows. For a home that size from Flemington to Doylestown, a full interior and exterior cleaning with screens, tracks, and frames usually falls in the $250 to $400 range. Two-story homes cost a bit more due to extra equipment and time for safe access. We give free estimates for your specific home.
Can professional window cleaning remove hard water stains?
Light mineral deposits from sprinklers or rain runoff usually come off during a standard cleaning. Heavy hard water stains require a specialized glass restoration treatment. These calcium and magnesium deposits bond to the glass and regular cleaners cannot dissolve them. We use professional-grade compounds to polish the glass back to clarity. Once removed, regular cleaning prevents them from returning.
