How Often Should You Pressure Wash in Las Vegas?

Every homeowner in Las Vegas has had the same moment. You pull into the driveway after a week of wind and realize your house looks like it aged five years. The stucco is coated in a fine tan film, the walkway has dark streaks, and the patio furniture has a gritty layer you can write your name in.

So you get it pressure washed. It looks amazing. Then two months later, you're right back where you started. The question isn't whether to pressure wash. It's how often.

The short answer (and why it's complicated)

For most Las Vegas homes, twice a year gets the job done. Once in spring to clear winter wind damage, once in fall after monsoon season. That covers about 80% of homeowners.

But "most" might not be you. Your cleaning schedule depends on your property's exposure, the surfaces involved, and how much punishment your exterior takes between cleanings.

What makes Las Vegas different from everywhere else

In Seattle, the enemy is moss and mildew. In Florida, it's algae and humidity. In Las Vegas, it's dust, mineral deposits, and UV damage, all happening simultaneously in a climate that barely rains.

Here's what's working against your exterior surfaces year-round:

Desert dust accumulation. The Mojave doesn't take days off. Fine alkaline particles settle on every horizontal and vertical surface, and without rain to wash them away, they build up layer by layer. A single dust storm can undo weeks of cleanliness in an afternoon.

Hard water staining. Las Vegas water runs 16-20 grains per gallon, some of the hardest municipal water in the country. Sprinkler overspray, irrigation runoff, and even condensation from your AC unit leave calcium deposits on concrete and stucco. Those white streaks don't brush off.

UV degradation. Las Vegas gets 294 days of sunshine per year. That constant UV exposure breaks down paint, fades stucco color, and makes dirt bond more aggressively to porous surfaces.

Monsoon season debris. July through September brings brief, intense storms that dump dust, sand, and organic debris on your property. The rain itself isn't enough to clean anything, just enough to turn dust into mud splatters.

Recommended cleaning frequency by surface

Not everything on your property needs the same schedule. Here's a practical breakdown:

Driveways and garage floors: twice a year. Spring and fall. If you park work vehicles that drip oil, or if your driveway gets heavy foot traffic, bump that to three times.

House exterior (stucco/siding): once or twice a year. Most Las Vegas homes have stucco, which is porous and holds dust. An annual cleaning keeps it looking maintained. Homes near construction zones or on busy roads might need it every six months.

Walkways and front entries: twice a year. These high-traffic areas show dirt faster and get noticed first by visitors. Spring and fall, same as driveways.

Pool decks: two to three times a year. Pool decks get wet constantly, which means mineral deposits build up faster. The combination of chlorinated splash-out and hard water creates stubborn white staining that looks worse the longer you wait.

Patios and outdoor living areas: once or twice a year. Covered patios can stretch to annually. Uncovered patios exposed to sun and dust need it every six months.

Fences and walls: annually. Block walls collect dust on the top and windward side. Once a year in spring keeps them from looking permanently stained.

Signs you're overdue for a cleaning

Sometimes the calendar isn't the best guide. Your property will tell you when it needs attention:

• Visible color difference between shaded and exposed surfaces
• White mineral deposits on concrete near sprinkler zones
• Dark streaks on walkways from foot traffic and irrigation
• Stucco that looks tan or gray when you know it's supposed to be white or beige
• Pool deck that feels gritty even after sweeping
• Neighbors just got theirs done and now yours looks rough by comparison (the peer pressure is real)

The cost of waiting too long

Skipping a year might not seem like a big deal, but it adds up. Mineral deposits that sit for 12+ months bond to concrete at a molecular level. What would have been a standard cleaning becomes a pre-treatment job with specialized chemicals, which costs more and takes longer.

Stucco that goes uncleaned for extended periods can develop permanent discoloration where dirt has penetrated the pores. At that point, you're looking at repainting rather than just washing.

On the financial side, a twice-yearly pressure washing schedule for a typical Las Vegas home runs $400-800 per year depending on property size. Neglecting it until the exterior needs deep restoration can easily hit $1,500-2,000.

Setting up a maintenance schedule that works

The easiest approach: pick two anchor dates and stick with them.

Early March: Right before temperatures start climbing. You clear off winter dust and wind damage, your property looks sharp for spring, and you're booking before the busy season rush.

Late October or early November: After monsoon season wraps up. The storms are done, temps are comfortable for cleaning, and your house looks good heading into the holiday season when you're most likely to have guests.

Put it on your calendar, set a reminder, or just tell your pressure washing company to auto-schedule you. Most will happily set up recurring service.
