Our Process
How We Clean Your Exterior Windows
Not every home is the same — and neither is every cleaning. Our technicians are trained in both systems and choose the right approach for your property.
Pure Water-Fed Pole System
Water is filtered through a multi-stage purification process that removes all minerals and contaminants. That ultra-pure water is fed through an extendable pole with a soft brush head that scrubs every inch of your glass. Because the water contains zero impurities, it leaves no residue when it dries — no streaks, no spots, no callbacks. Ideal for most residential exteriors and upper-storey windows.
Traditional Mop and Squeegee
The time-tested method used by professional window cleaners worldwide. A professional-grade scrubbing mop loosens dirt and grime, and a precision squeegee removes it cleanly in one pass. In the hands of a trained technician, this method delivers an exceptional finish — especially on certain glass types, frames, and property layouts where it outperforms pole systems.
We choose the method that's right for your home. That's the difference between a company with one tool and a company with real expertise.
