Brick Chimney & Exterior Brick Cleaning in Mebane, NC: What's Safe and What Isn't

Brick gives a Mebane home that timeless, durable look — but over time, mortar darkens, algae creeps up the lower courses, and chimneys develop ugly green or black streaks. Cleaned correctly, brick can look almost new for decades. Cleaned wrong, the damage is permanent and expensive. Here's what every brick-home owner in the NC Piedmont should know.

Why Brick Gets Dirty

• Mortar absorbs moisture and harbors algae and mildew
• Chimneys sit above the roof and catch every drop of rain — plus creosote and soot from inside
• Lower courses get soaked from rain splash off bare ground
• North-facing walls stay damp and develop green algae
• Efflorescence (white crystalline deposits) shows up when moisture moves salts to the surface

The Big Mistake: High Pressure on Brick

Brick looks tough, but the mortar between bricks is much softer. A high-pressure wand will:

• Erode mortar joints, sometimes blowing them out completely
• Expose brick to water intrusion, leading to spalling and freeze-thaw damage
• Force water behind the wall, where it can rot framing and grow mold
• Damage the brick face, especially on older or softer brick

What Pros Use on Brick

The correct method is soft washing — the same low-pressure approach used on roofs and siding:

• Pre-rinse to wet the surface and protect mortar
• Apply a biological cleaner that kills algae, mildew, and mold at the root
• Allow 10–15 minutes of dwell time for the cleaner to work
• Low-pressure rinse with a wide fan tip from top to bottom
• Spot treat efflorescence with a brick-safe acidic cleaner if needed

Cleaning Brick Chimneys

Chimneys are a special case because of access, height, and the variety of staining:

• Algae and mildew — soft wash from a ladder or roof
• Creosote bleed-through — specialty cleaner; sometimes the staining is permanent
• Soot from outside burning — usually cleans up well
• White efflorescence — light acid wash and neutralizing rinse

We never put high pressure on a chimney — the mortar at the cap and crown is critical for keeping water out of your home, and damaging it leads to expensive repairs.

What Painted Brick Needs

Painted brick is even more pressure-sensitive than bare brick. We use the lowest practical pressure with a gentle biological cleaner. Aggressive washing can lift paint, especially on south-facing walls where UV has weakened the bond.

How Often Should Brick Be Cleaned in Mebane?

• Brick siding and walls: every 2–3 years
• Brick chimneys: every 3–5 years (or sooner if streaking is visible)
• Brick patios and walkways: annually
• Painted brick: every 2–3 years with the gentlest possible approach
