Pressure washing seems simple—until it isn’t. Many homeowners grab a rented washer and jump into cleaning driveways, siding, or patios… only to end up with damaged surfaces, streaks, or worse.

At Bright & Shiny Window Cleaning & Pressure Washing, we see it all the time. Here are 5 common pressure washing mistakes homeowners make—and how our professionals avoid them.

1. 💥 Using Too Much Pressure

More power isn’t always better. Many DIYers use excessive PSI, which can:

  • Strip paint
  • Crack stucco
  • Etch concrete
  • Damage wood and siding

Our approach: We match the pressure to each surface and use soft washing where needed to prevent damage.

2. 🧼 Cleaning Without Pre-Treatment

Spraying dirt with water alone won’t remove mold, algae, or oil. Skipping pre-treatment wastes time and water—and leaves behind stains.

Our approach: We apply biodegradable cleaners that break down buildup before washing, ensuring a deeper clean with less risk.

3. 🎯 Washing in the Wrong Direction

Improper spray angles can drive water behind siding, under shingles, or into windows—causing hidden water damage or mold growth.

Our approach: We know the right direction and distance to clean safely and avoid structural issues.

4. ⚠️ Ignoring Safety Risks

Slippery surfaces, flying debris, and high-pressure nozzles pose serious risks—especially on ladders or uneven ground.

Our approach: We use proper safety gear, commercial equipment, and a trained team to complete every job safely and efficiently.

5. ❌ Using the Wrong Equipment

Home pressure washers lack the power and control needed for effective, safe cleaning. Cheap nozzles or hoses also lead to poor results—or broken fixtures.

Our approach: We invest in professional-grade machines, adjustable nozzles, and surface cleaners to deliver flawless results every time.
