Our process
Most streaks are not technique, they are chemistry. Ordinary water leaves dissolved solids behind when it dries. Remove them first and the glass dries clear on its own.
Tap water carries dissolved minerals. Wash a window with it and the water evaporates while the mineral stays behind. That residue is most of what people call streaks — it is not the technique, it is what was in the water.
Sediment, then carbon, then a reverse-osmosis membrane. By the time water reaches the pole it has nothing dissolved in it to leave behind. On well water — common out toward Magnolia — that is the entire difference between a clean window and a spotted one.
Pure water sheets off the glass and dries with nothing in it. No squeegee marks, no towel lines, no dried edges where a cloth stopped. Nobody has to touch the pane to finish it.
A water-fed pole reaches second and third-storey glass from the ground. Safer for the crew, and no ladder feet in your flowerbeds or against your gutters. Above three storeys it becomes lift work, which we quote on the job.
There is no detergent in the system, so nothing runs off into a bed or down a driveway. It is plain water with the minerals taken out.
