“Why is my house turning green?” “Why does my building look so dirty?”

These questions are common for Knoxville residents as this Tennessee city is known for its humidity, seasonal pollen, and heavy rains. Over time, you may have noticed that your home or business has been looking dirtier and less appealing.

This may indicate deeper problems that require more attention. To have a clean-looking building and have longer-lasting structures, it’s important to know the source of the problem and have a clear solution.

1. Mold & Mildew

Mold and mildew thrive in areas that are shaded, damp, and cool. It’s often found on siding, decks, fences, and roofs. Not only can this be unsightly, but it can cause damage to your building.

Why It’s a Problem:

• Causes Wood Rot
• Weakens Structural Integrity
• Triggers Allergies
• Triggers Respiratory Issues
• Creates Black or Green Streaks

Removal:

It’s best to clean with a combination of soft washing and biodegradable cleaning solutions for a thorough clean that protects the structure underneath.

2. Algae Growth

Algae also tends to grow in areas that are moist and shaded. It tends to appear on roofs, driveways, and siding, leading to a dirty, green building.

Why It’s a Problem:

• Creates Slippery Surfaces
• Eats at Roofing Materials
• Makes Homes Look Dirty & Neglected

Removal:

Low-pressure washing with an algaecide treatment is best for safely removing the algae and preventing further growth, an essential step in the spring.

3. Pollen & Dust

Especially in the spring, pollen and dust can collect on windows, exterior walls, porches, and driveways, making a building look dirty and creating some unwanted allergies.

Why It’s a Problem:

• Yellow or Brown Film
• Accumulation Can Cause Gutter Issues
• Allergic Reactions for Guests or Visitors

Removal:

To ensure a welcome and clean environment for everyone, it’s best to have exterior cleaning services, like regular pressure washing, especially in the springtime.

4. Lichen & Moss

Though lichen and moss can add character to a building, it can end up being dirty and problematic for roofs, decks, and brick surfaces.

Why It’s a Problem:

• Roots Deteriorate Shingles & Brick Mortar
• Creates Slippery Surfaces
• Can Cover Solar Panels

Removal:

Soft washing with a biodegradable solution can help address the growth and tackle the deeper root without damaging surfaces.

5. Oil & Grease

Oil and grease can collect in driveways, parking lots, and garage floors, which can ruin the look of your home or business. It can quickly become a safety issue as well as an eyesore.

Why It’s a Problem:

• Unsightly Dark Stains
• Diminished Curb Appeal
• Potential Slip Hazard
• Difficult to Remove

Removal:

For a thorough removal that not only eliminates the oil and grease on the surface but fully clears it away, high-pressure washing and a degreasing agent can break down the dirty substances.

6. Rust Stains

Rust can develop over time if a metal area is not properly being maintained. This not only ages the appearance of your building, but it can indicate bigger issues that need to be addressed.

Why It’s a Problem:

• Diminishes Professional Appearance
• Indicates Metal Corrosion
• Sign of Further Maintenance
• Difficult to Remove

Removal:

To clear away the rust and protect your metal structures, it’s best to treat it with specialized rust removers and low-pressure washing to remove the rusty marks and protect the material.

7. Graffiti & Paint Stains

Graffiti is commonly found in public places, sticking to the sides of commercial buildings, fences, and other public structures. Not only are these dirty stains unwelcome, but they can actually be problematic for your property.

Why It’s a Problem:

• Impacts Property Value & Reputation
• Decreased Curb Appeal
• Tough to Remove
• Over-the-Counter Removers Can Cause Damage

Removal:

To fully remove the marks from graffiti, hire professional pressure washing services that have eco-friendly graffiti removers. This will help to lift the paint without harming the underlying material.
