If you live in the Lowcountry, you know that heat, humidity, and salty air can wreak havoc on your home’s exterior. Algae, mildew, mold, and grime build up fast, especially on siding, driveways, and roofs. However, when it’s time to clean it all off, many homeowners wonder whether they should pressure wash or use a soft wash. And what’s the difference anyway?
In this blog, our Charleston exterior washing team will break it down and help you choose the right method for your Charleston home.
What Is Pressure Washing?
Pressure washing uses high-pressure water (typically over 2,000 PSI) to blast away tough stains, dirt, and debris. It’s a powerful solution for the following surfaces:
- Concrete driveways
- Brick walls
- Stone patios
- Sidewalks
- Paver surfaces
It’s great for durable materials, but it’s too aggressive for delicate surfaces and can actually damage wood, vinyl siding, and especially roof shingles if misused.
What Is Soft Washing?
Soft washing utilizes low-pressure water combined with specialized cleaning solutions to remove organic growth gently, such as mold, algae, and mildew. It’s the safer choice for:
- Vinyl and wood siding
- Stucco
- Roofs (shingle, metal, or tile)
- Decks and fences
- Screened porches
The cleaning agents do the heavy lifting, breaking down buildup at its root so it doesn’t return quickly.
Which is Best for Charleston Homes?
Due to the humid, coastal environment, homes in the Charleston area are particularly susceptible to algae and mold. This makes soft washing ideal for most residential applications, especially for:
- Roofs with black streaks or green buildup
- Homes near marshes or shaded areas
- Painted or older siding
- Homes with wood features like porches or shutters
Power washing, on the other hand, is perfect for keeping concrete and brick surfaces looking fresh—think driveways, pool decks, and walkways.
