Frequently Asked Questions (FAQs) - Soft Washing & Pressure Washing in Hickory Hills and Oak Lawn, IL

At Streamline Softwash, based in Hickory Hills, IL, we understand the importance of maintaining the beauty and integrity of properties in our local communities, including Oak Lawn and surrounding areas. We've compiled a list of frequently asked questions to provide you with clear, informative answers about our soft washing and pressure washing services.

What is Soft Washing?

Soft washing is a low-pressure cleaning method
(80 PSI or less) that combines specialized cleaning solutions to break down and remove mold, algae, bacteria, fungus, moss, and other organic buildup. Unlike high-pressure washing, soft washing is gentle yet highly effective, making it the best choice for delicate surfaces like roofs, siding, and decks. This method not only cleans but also prevents organic growth from returning, extending the lifespan of your exterior surfaces.

Is Soft Washing Safe?

Yes! Soft washing is completely safe for your home, family, pets, and landscaping. Our eco-friendly, biodegradable cleaning detergents break down naturally without harming the environment. Additionally, our low-pressure application ensures that delicate surfaces such as roofing shingles, wood decks, and vinyl siding are cleaned without damage.

What is the Difference Between Soft Washing and Pressure Washing?

The primary difference between soft washing and pressure washing is the pressure level and cleaning method used.

Soft Washing

• Uses low-pressure water (80 PSI or less) combined with specialized detergents.
• Ideal for delicate surfaces like roofs, siding, fences, and decks.
• Cleans and sanitizes surfaces, preventing the regrowth of mold, algae, and bacteria.

Pressure Washing

• Uses high-pressure water to remove dirt, grime, and stains.
• Best suited for hard, durable surfaces such as driveways, sidewalks, and patios.
• Effective for deep-set stains, grease, and heavy debris removal.

What Can You Soft Wash?

Soft washing is ideal for surfaces that require a gentle yet thorough cleaning method. We use this technique to clean:

• House Siding (Vinyl, Stucco, Wood, and Brick) - Removes dirt, algae, and mildew without forcing water behind the material.
• Roof Shingles (Asphalt, Tile, and Metal) -
• Eliminates black streaks and prevents premature roof aging.
• Decks & Fences (Wood, Vinyl, and Composite) - Cleans without splintering or warping.
• Windows & Screens - Prevents cracks and damage while achieving a streak-free clean.
• Gutters & Downspouts - Removes oxidation stains, mildew, and debris buildup.
• Outdoor Furniture & Playsets - Keeps plastic, wood, and wicker surfaces mold-free.
• Delicate Stone & Pavers - Preserves the integrity of porous or sealed stone surfaces.

What Can You Pressure Wash?

Pressure washing is ideal for durable surfaces that need deep cleaning. We use this method for:

• Concrete Driveways & Walkways - Removes oil stains, dirt, and grime.
• Brick & Stone Patios - Clears moss, weeds, and buildup between pavers.
• Garage Floors - Lifts stubborn grease, oil, and tire marks.
• Retaining Walls - Restores the original look of brick, stone, and concrete walls.
• Parking Lots & Commercial Entrances Cleans high-traffic areas efficiently.
• Heavy Equipment & Machinery - Removes grease, grime, and industrial buildup.

What Are the Black Streaks on My Roof?

The black streaks commonly seen on roofs are caused by Gloeocapsa magma, a type of bacteria that thrives in humid and shaded areas.
This bacteria feeds on the limestone in asphalt shingles, spreading over time and making roofs appear dirty.

Are Black Streaks Harmful to My Roof?

Yes! Black streaks can significantly damage your roof by:

• Weakening shingles and reducing their ability to reflect UV rays.
• Accelerating granule loss, leading to premature roof aging.
• Creating conditions for moss and lichen growth, which can lift shingles and cause leaks.

Soft washing removes these bacteria safely, preventing further damage and extending your roof's lifespan.

Why Does Mold Grow on Siding?

Mold, mildew, and algae grow on siding due to a combination of dirt accumulation, moisture, and lack of sunlight.

Causes of Mold Growth on Siding

• Dirt Accumulation - Organic matter provides food for fungi.
• Moisture - Excess moisture trapped on or behind siding fosters mold growth.
• Shady Areas - Mold thrives in damp, dark locations.

Regular soft washing prevents mold buildup, keeping your siding clean and preserving its durability.

What Payment Methods Do You Accept?

We accept all major credit cards, debit cards, and cash payments for your convenience.
