Our Technology
The Xero Pure DI System
Most window cleaners use soap — which leaves residue, requires rinsing, and often causes streaks. We use something better.
1
Purified Water
Tap water passes through the Xero Pure deionization (DI) filter, removing all minerals, dissolved solids, and impurities — reaching 0 PPM (parts per million). Completely pure.
2
Water-Fed Pole System
The purified water is pumped through a specialized water-fed pole with a soft brush head. We scrub your windows safely from the ground — no ladders needed, even for upper-story windows.
3
Spot-Free, Streak-Free Rinse
Pure water acts like a magnet for dirt and grime, lifting it off the glass. Because there are no minerals in the water, it dries completely clear — no spots, no streaks, no residue. Ever.

Why Pure Water Works
Ordinary tap water contains dissolved minerals. When it dries on glass, those minerals are left behind — that's what causes spots and water marks.
Deionized water has zero dissolved solids. When it dries, there is nothing left behind. The result is chemically perfect glass.

Questions
Frequently Asked
What is the Xero Pure DI system and is it safe?
The Xero Pure DI system filters tap water through a deionization (DI) resin that removes all dissolved minerals and impurities, bringing the water to 0 PPM (parts per million). The result is ultra-pure water that cleans glass without any soaps or chemicals. It's completely safe for your glass, your sills, your plants, and your pets.
How do you clean upper-story windows without ladders?
We use a water-fed pole system connected to our Xero Pure purified water supply. The pole extends far enough to reach upper floors safely from the ground. The soft brush agitates the glass while pure water rinses everything away — no ladders needed against your home.
Will the windows really dry without spots?
Yes — that's the magic of deionized water. Because there are literally zero dissolved solids in the water, there is nothing left behind when it evaporates. No mineral deposits, no water marks, no spots. Just clear glass.
Do I need to be home during the cleaning?
In most cases, no. We clean exterior windows, so you're welcome to be away while we work — just unlock any gates and secure any pets. The only time you'll need to be home is if some of your windows can only be reached from inside an enclosed space — for example, a screened-in or upstairs porch we can't get to from the outside. One small request: if your windows have screens and you won't be home, please take them out beforehand so we can get the glass spotless. (Interior cleaning is coming soon!)
Are you insured?
Yes, we carry full general liability insurance. Proof of coverage is available on request before your appointment.
How do I get a quote?
Fill out the form above or give us a call. We'll get back to you quickly with a transparent, no-obligation estimate based on your window count, access, and any special conditions.
