Thinking about pressure washing your own patio this weekend? Good for you. Plenty of homeowners in Northern Kentucky do it themselves, and done right, it works fine. Here’s how we’d tell a neighbor to do it, plus an honest word about when it makes sense to call us instead.
Step 1: Clear and sweep
Move the furniture, planters, and the grill. Sweep off leaves and loose dirt. Anything left on the patio becomes a shadow stain once you start washing around it.
Step 2: Pick the right nozzle
This is where most DIY damage happens. For concrete, use a 25 degree (green) tip. Never use a 0 degree (red) tip on anything. It can carve lines into concrete that never come out. For pavers, back off even further, because high pressure blasts the sand right out of the joints.
Step 3: Use a cleaner, not just water
Plain water pushes dirt around. A concrete detergent breaks down the algae and grime so the pressure can lift it. Apply it, let it sit ten minutes without drying, then wash.
Step 4: Keep the wand moving
Work in overlapping strips, like mowing a lawn, and keep the tip a consistent 12 inches or so off the surface. Stopping in one spot even for a second leaves a mark.
Step 5: Rinse everything around you
Rinse your siding, plants, and door hardware when you’re done. Detergent left to dry on glass and metal leaves spots.
When to call a pro instead
A rental machine handles a lightly dirty patio fine. Call a professional when you’re dealing with years of buildup, oil or rust stains, stained pavers, or any surface you’re not sure about. We clean with hot water and commercial equipment that removes what rental units simply can’t, and we carry the insurance in case anything goes wrong. That’s the real difference.
