The surfaces that slowly go from tan to gray
In San Tan Valley, the outside of a house takes the same beating the windows do. Monsoon dust settles on every flat surface, sprinklers spray the same strip of concrete and stucco day after day, and the sun bakes all of it in place. Over a few seasons, a light driveway turns dark and a block wall picks up a white or discolored band along the bottom.
Power washing covers the hard surfaces around your home:
- Driveways, including tire marks and oil or drip spots where cars park
- Patios, covered or open, plus the slab around a pool if you have one
- Walkways, front entry paths, side yards, and the path to the back gate
- Stucco, which should be washed with lower pressure to protect the finish
- Block walls, garden walls, and the base of the house where sprinklers hit
Why concrete and stucco need different handling
Concrete can take more pressure than most surfaces around a home. Stucco can't. Too much pressure, or a tip held too close, can cut into a stucco finish or force water behind it. A careful cleaner adjusts pressure and nozzle for each surface and may use a soft wash approach on stucco and painted walls.
Some stains will lighten but not fully disappear. Old oil that has soaked deep into concrete, and mineral staining that has been building for years, may need more than one pass or a specialty cleaner. Ask the cleaner what to expect for your stains before the work starts.
Sprinkler stains on walls and concrete
The white crust and discolored streaks along the bottom of many walls here come from minerals left behind as irrigation water dries on the surface over and over. It is the same mineral problem that spots windows, covered on the hard water stain removal page. Washing can remove much of the buildup, but if the sprinkler keeps hitting the wall, it will come back. Adjusting the spray heads is the long-term fix.
When to schedule it
After monsoon season is a good time for power washing, once the last storms have finished depositing dust, or before hosting (holidays, a party, or listing a house). Pairing it with a window cleaning visit makes sense, since washing walls and patios can splash dirty water onto nearby glass.

Common Questions
Will power washing damage my stucco?
It can if the pressure is too high or the tip is held too close. Stucco should be washed with lower pressure or a soft wash method. Ask the cleaner how they handle stucco before the work starts.
Can oil stains be removed from a driveway?
Fresh spots often lighten a lot. Older oil that has soaked into the concrete may lighten but not fully disappear. Send a photo with your quote request and ask what to expect.
Do I need to be home?
Usually not for outside work, as long as the cleaner can reach an outdoor water spigot and any gates are unlocked. Confirm this with the cleaner when you get your quote.
How often should a driveway or patio be washed here?
Once a year is a common schedule, often after monsoon season. Homes with heavy sprinkler overspray or a lot of foot traffic may want it more often.
