Shark Power Washing has served the Wilmington area for 20 years with expert pressure washing… and we’ve seen a thing or two in that period of time. Pressure washing is one of the best ways to protect and improve your home’s exterior — but it’s also one of the most misunderstood. In a coastal area like Wilmington, NC, misinformation can lead to damaged surfaces, wasted money, or skipped maintenance that ends up costing more in the long run.
Let’s clear things up. Below are seven common pressure washing myths we hear from homeowners, along with what actually works.
Myth #1: Higher Pressure Means a Better Clean
This is the most common myth — and one of the most dangerous.
More pressure does not equal better results. In fact, excessive pressure can damage siding, strip paint, loosen shingles, and force water behind surfaces. Professional pressure washing is about using the right amount of pressure for each surface, and often that means soft washing, not high pressure.
Soft washing safely removes mold, algae, and mildew at the root — instead of just blasting away surface stains that quickly return.
Myth #2: Pressure Washing Is Only About Curb Appeal
A freshly soft washed house looks great, but pressure washing isn’t just cosmetic.
In Wilmington’s humid coastal climate, organic growth like mold and algae can:
- Hold moisture against siding and roofing
- Break down exterior materials over time
- Lead to premature wear and costly repairs
Routine exterior cleaning helps protect your home, not just improve how it looks.
Myth #3: DIY Pressure Washing Is Always Cheaper
Renting or buying a pressure washer seems like a money-saver — until something goes wrong.
DIY pressure washing often leads to:
- Streaking and uneven results
- Damaged siding, trim, or window seals
- Water intrusion behind siding
- Growth returning quickly because it wasn’t treated properly
Professional equipment, training, and cleaning solutions produce longer-lasting results without putting your home at risk.
Myth #4: Pressure Washing Damages Every Type of Siding
Pressure washing only causes damage when it’s done incorrectly.
Different surfaces require different methods. Vinyl siding, brick, stucco, wood, and roofing materials all respond differently to cleaning. A professional company knows when to use pressure, when to soft wash, and when to adjust techniques to protect your home.
Damage usually comes from improper DIY methods — not professional service.
Myth #5: Pressure Washing Is Harmful to Plants and Pets
This is a common concern, and a fair one.
When done properly, professional pressure washing is safe for landscaping and pets. At Shark Power Washing, we use professional-grade cleaning solutions that are applied carefully, diluted correctly, and thoroughly rinsed. We also take steps to protect plants before cleaning begins.
Improper use of harsh store-bought chemicals is often more harmful than professional treatments.
Myth #6: Roof Cleaning Uses High Pressure
High pressure should never be used on a roof.
Professional roof cleaning relies on non-pressure soft washing to remove black streaks, algae, and organic growth without damaging shingles. Using high pressure on a roof can shorten its lifespan and void warranties.
If a company talks about “pressure washing” your roof, that’s a red flag.
Myth #7: You Only Need Pressure Washing When Things Look Really Dirty
By the time heavy algae or mold buildup is visible, it’s often already affecting the surface underneath.
Regular maintenance cleaning:
- Prevents heavy staining
- Reduces long-term wear
- Keeps exterior surfaces healthier
- Saves money over time
Most homes in coastal North Carolina benefit from professional exterior cleaning once per year, with some homes needing more frequent service depending on shade and proximity to the water.
