The difference between a rental-machine weekend and a pro finish isn’t the machine — it’s the method. Here are the techniques our crew uses on every job, adapted for homeowners who want to understand what great looks like.
1. Let the soap do the work
Pressure removes what’s loose; detergent removes what’s bonded. Apply house-wash soap bottom-to-top, give it five to ten minutes of dwell (never let it dry), and you’ll need half the pressure for twice the result.
2. Keep a consistent distance
Stripes happen when distance changes. Pick twelve inches for concrete, eighteen for siding, and lock your arms — move your feet, not your hands. Overlap every pass by a third, like mowing a lawn.
3. Work with the grain and the weather
Wash decks along the boards, rinse siding top-to-bottom, and never wash in direct midday sun if you can avoid it — detergent dries too fast and leaves film. Early morning is the pro’s window.
4. Know when to stop
Roofs, old mortar, oxidized paint, and capped composite punish high pressure. If the surface is delicate, it wants a soft wash — low pressure plus the right chemistry. That judgment call is the most valuable thing a pro brings.
5. Rinse like you mean it
Half of all “streaky” results are dried detergent, not dirt. Rinse twice: once to remove grime, once with fresh water to remove residue. Windows especially — soap film bakes into spots by afternoon.
