Window Cleaning
Chemical-free window cleaning using reverse osmosis and deionized water. Spotless, streak-free results every time.
Clean windows make your whole house look better. But Florida's hard water, pollen, and salt air leave spots and film that regular cleaning cannot touch. Our reverse osmosis and deionized water system gets your windows spotless without any chemicals.
Why deionized water works better
Regular tap water leaves minerals behind when it dries. That is what causes water spots. Deionized water has those minerals removed, so when it dries, it leaves nothing behind. No spots, no streaks, no residue. Just clean glass.
No chemicals, no ladders
We use water-fed pole systems that reach second-story windows from the ground. No ladders leaning against your house, no risk of damage to your siding or landscaping. And because we use pure water instead of chemicals, there is nothing running down your walls that could harm plants or pets.
Interior and exterior
We clean the outside of your windows with the water-fed system and the inside by hand with professional squeegees. Screens, tracks, and sills get cleaned too. When we are done, your windows look brand new.

FAQ
Window Cleaning, common questions
What is deionized water cleaning?
Deionized water has minerals removed so it dries without leaving spots or streaks. It is the cleanest way to wash windows.
Do you clean inside and outside?
Yes. We clean both sides of every window, plus screens and tracks. Your windows will be spotless inside and out.
Is the process safe for my landscaping?
Yes. We use pure water with no chemicals. Nothing harmful runs off your windows onto your plants or lawn.
How often should windows be cleaned in Florida?
Two or three times a year keeps most Florida windows clear. Salt air near the coast, summer storms, and sprinkler overspray all leave film and spots faster than in other states. Our deionized water process dries without streaks, so the results last. We can pair window cleaning with your regular gutter cleaning visit to save you a trip.
