7 Signs Your St. George Driveway Needs Pressure Washing
A St. George driveway is due for pressure washing when the concrete has gone pink or tan from red dust, shows rust-colored fans near the sprinklers, or has dark joints, oil spots, or slick patches a hose will not move. If you see two or more of those, text a photo or call 435-773-8856 for a free estimate.

Concrete in Washington County does not get dirty the way it does back east. There are no piles of wet leaves. What you get is fine red dust, hard water, and a lot of sun, and they work on the slab a little every day. Most people do not notice until a neighbor's driveway gets cleaned and theirs suddenly looks a shade darker. Here are the seven things we look for when someone asks if their driveway is ready.
1. The concrete looks pink or tan instead of gray
Walk out to the street and look back at the house. If the driveway reads as pink, salmon, or a dull tan, that is red dust packed into the surface. Broom-finished concrete has thousands of tiny grooves, and the dust from the cliffs and empty lots settles in them and stays. A garden hose moves the loose layer on top, but the color comes right back once it dries. A proper wash lifts that packed film out of the texture so the slab looks like concrete again. If only the lower half by the street is pink, runoff is carrying the dust down, which is useful to mention when you call.
2. Rust-colored fans where the sprinklers hit
Look at the edges of the driveway near lawn heads or drip lines. Orange or brown arcs in a fan shape usually mean irrigation water has been spraying the concrete and drying there, over and over. That water carries minerals and iron, and the sun bakes the marks in. These fans do not wash off with plain water and often need a treatment after the main wash. Our iron oxide stain guide explains why. The other half of the fix is free: turn or adjust the heads so they stop hitting the slab, or the fans come back by next summer.
3. Dark lines in the joints and cracks
Expansion joints and hairline cracks catch everything. Dust, sprinkler water, bits of plant matter, and shade all collect there, and the lines turn dark brown or nearly black. Sometimes weeds start poking through. Dark joints make an otherwise decent driveway look old, and the gunk holds moisture against the edges of the concrete. A surface cleaner does most of the flat area, but joints usually need a wand pass and a little extra time. If weeds are rooted deep in a joint, pull them before the visit so the wash can get the dirt that is left behind.
4. Oil drips and tire marks where you park
Every parking spot ends up with a few drips and a pair of dark tire stripes. On hot afternoons the tires are soft and leave more behind than you would think. Fresh oil can often be lifted most of the way with the right cleaner and some dwell time. Old oil that has soaked in for years may only lighten, and we would rather tell you that up front than promise a brand new slab. Point the spots out when you text a photo. Oil is a different cleaning job from red dust, and it helps to plan for it before the truck shows up.
5. It feels slick when it gets wet
Run your shoe across the driveway after the sprinklers run or after a summer storm. If it feels slippery, there is a film on the surface. In shady corners it may be a thin layer of algae or mildew. Near the garage it is often a mix of dust, tire residue, and oil. On sloped St. George driveways, that slick layer is a real slip risk for kids, older family members, and anyone hauling trash cans to the curb. Washing removes the film and brings back the grip of the concrete. Pool decks get the same problem, and we cover that on the pool deck cleaning page.
6. A hose rinse does not change anything
Here is a simple test. Spray a section of the driveway with a regular hose nozzle and let it dry. If it looks exactly the same as the section next to it, the dirt is bonded to the surface, not sitting on top. That is the point where rinsing becomes wasted water. Pressure, the right tip, and a surface cleaner do what a hose cannot, and a pre-treatment helps with mineral film. If you are standing out there every weekend with a hose and nothing changes, save the water and the time. It is ready for a real wash.
7. You are about to sell, rent, seal, or get an HOA notice
Some driveways are not terrible, but something is coming up. A listing photo, a new tenant, a short term rental guest, or a plan to seal the concrete all go better on a clean slab. Sealer locks in whatever is on the surface, so the slab has to be clean and dry first. In communities with an HOA, a letter about stained concrete is a common reason people call. If you manage several homes or a whole street, our HOA pressure washing page explains how we handle multiple driveways and shared walks in one trip.
What to do next
If one of these signs fits, it is worth a look. If three or four fit, the driveway is overdue. Snap a daylight picture of the full driveway from the street, plus a close shot of the worst stain, and text it to 435-773-8856. Tell us the city and whether any sprinklers hit the slab. We will tell you if it is a straight wash or if stains will need a treatment too. You can read more about the service itself on the driveway pressure washing page. We do not post prices, and estimates are free. See pricing for what changes a quote.
Questions
How often should a St. George driveway be pressure washed?
It depends on dust, sprinklers, and how much you park outside. Many homes here look best with a wash about once a year, and sooner if sprinklers hit the slab or you are selling.
Will pressure washing remove the rust-colored marks from my sprinklers?
The wash removes the dirt and film. Rust-colored fans from irrigation water often need a separate treatment afterward, and very old marks may lighten rather than disappear.
Can pressure washing damage my concrete?
It can if the pressure or tip is wrong for the surface. We match pressure to the concrete and keep a lighter touch on stamped borders and exposed aggregate.
Do I need to be home for a driveway wash?
Usually not. Move the cars, leave an outdoor faucet we can hook up to, and make sure gates are unlocked. Call or text 435-773-8856 to set it up.
Should I seal my driveway after washing it?
Sealing is optional. If you plan to seal, the concrete has to be clean and fully dry first, so the wash always comes first.
