Our Process
How We Clean From Start to Finish
01
Walk the Patio
We look at the surface, check for algae, mildew, grease near the grill, and rust spots. We also flag pavers that have lost joint sand so you know what to expect after the wash.
02
Move What Needs to Move
Outdoor furniture, planters, and grill covers come off the patio first. If you have a hot tub or built-in grill, we work around it and protect the panels and electronics.
03
Pressure Wash the Surface
We match pressure and tip to the patio material, lighter on pavers and brick, firmer on sound concrete. Algae on shaded north-facing slabs gets pre-treated so it actually lifts instead of streaking.
04
Rinse and Final Walk
We rinse the patio, sweep water away from the door, and walk the area with you. If pavers need joint sand, we point that out so you can decide whether to re-sand.
Before Your Appointment
What to Expect From Patio Pressure Washing
Move Furniture First
Patio furniture, planters, rugs, and grill covers should be off the patio before we start. If you cannot move it, tell us ahead of time and we will plan around it.
Pavers and Joint Sand
Paver joints often lose sand during a wash, especially older patios. We point out which sections need re-sanding so the joints stay locked and weeds stay down.
Algae and Mildew
North-facing or shaded patios usually have algae or mildew, not just dirt. We pre-treat those areas so the wash lifts the growth instead of just spreading it around.
Hot Tubs and Grills
We work around hot tubs, built-in grills, and outdoor kitchens without spraying control panels or burners. Tell us about anything sensitive when we book the job.

How Much Does Pressure Washing Cost in St. George?
Estimate concrete, patio, porch, walkway, garage floor, or driveway cleaning by square footage.
Efflorescence
That white haze on stamped concrete is mineral, not dirt
When patio pressure washing in St. George turns up a chalky white film on stamped concrete or pavers, that is efflorescence. Water moves through the slab, picks up calcium and salts, and leaves the minerals on the surface as it dries.
Plain pressure does not pull it out. We pretreat with an efflorescence cleaner that breaks the bond chemically, then rinse it off the surface so the color underneath comes back instead of looking washed out and gray.
Paver joint sand
Why we keep the wand off the joint lines on paver patios
Paver patios hold their shape because of polymeric sand packed between the stones. Hit those joints straight on with a 0 or 15 degree tip and the sand blows out, the pavers shift, and weeds find their way in within a season.
We angle the wand across the pavers instead of into the joints, drop the pressure, and flag the sections that lost sand during the wash. After the patio dries for a couple of days, re-sanding locks the joints back down before the next storm.
Local Expertise
Why Patio Pressure Washing Takes Local Judgment in St. George
Backyard slabs in St. George, Washington, and Santa Clara catch red dust from every windy afternoon, plus sprinkler overspray that leaves a film on the concrete. North-facing patios and shaded corners by the house also grow algae and mildew that a hose will not touch.
Most calls we get are tied to a date: a graduation party, a family visit, a BBQ, or a holiday weekend. Booking a week or two ahead gives the patio time to dry fully and lets us flag any joint sand or sealing work before the guests show up.
Paver patios and stamped concrete need a lighter touch than driveways. Pavers can lose joint sand during the wash and may need re-sanding, and stamped patterns hold algae in the low spots, so we adjust how we work the surface.
Common Questions
Questions About Patio Pressure Washing in St. George
Do you pressure wash paver patios or only concrete?
We do both. Pavers need lighter pressure and the joint sand can wash out, so we point out sections that may need re-sanding after the patio dries.
Can you clean a patio before a party or BBQ?
Yes, that is most of what we do. Book a few days ahead so the patio dries fully and you can put the furniture back before guests arrive.
Will pressure washing get rid of algae and mildew on a shaded patio?
Yes, when we pre-treat the area first. Plain pressure on algae usually streaks and leaves spots, so the pre-treatment is the part that actually does the work.
Do I need to move my patio furniture first?
Yes, the patio should be clear before we start. If a heavy piece cannot move, let us know and we will work around it the best we can.
Can you wash around my hot tub or built-in grill?
Yes. We keep water away from control panels, burners, and electrical, and we ask about anything sensitive before we start the wash.
