The Benefits of Sealing Brick Driveways and Walkways: Protecting Your Nashville Home Investment

Wondering if sealing your brick driveway or walkway is worth it? In short — yes, it absolutely is.
In Nashville’s humid climate, seasonal rain, and temperature swings, unsealed brick surfaces can absorb moisture, leading to cracks, fading, and long-term damage.

Sealing your brick is a simple, cost-effective way to preserve its beauty, prevent costly repairs, and extend its lifespan by years.

Why Should You Seal Brick Driveways and Walkways in Nashville?

Brick driveways and walkways add warmth and character to any property, but they’re also exposed to daily wear and Tennessee’s unpredictable weather. Here’s what happens when brick isn’t sealed:

• Moisture absorption causes cracking and crumbling over time
• Mold, mildew, and efflorescence (the white powdery residue) can form
• UV rays fade brick color and weaken mortar joints
• Freeze-thaw cycles lead to flaking and chipping in colder months

Sealing creates a protective barrier that keeps moisture, dirt, and chemicals out while enhancing color and surface strength.

How Brick Sealing Protects Your Investment

A high-quality masonry sealer does more than just make brick look good — it safeguards your entire structure. Here’s how:

1. Prevents Water Penetration: Stops rainwater and runoff from soaking into brick pores.
2. Reduces Mold & Algae Growth: Keeps the surface cleaner and more sanitary.
3. Preserves Color & Finish: UV-resistant sealers prevent fading and discoloration.
4. Prevents Salt & De-Icer Damage: Especially important for driveways exposed to winter treatments.
5. Minimizes Maintenance: Makes cleaning easier and extends the lifespan of your masonry.

Think of sealing as applying sunscreen for your brick — it keeps it looking younger, longer.

How Often Should Brick Be Sealed?

For most Nashville properties, brick driveways and walkways should be sealed every 3–5 years. High-traffic areas or surfaces exposed to constant moisture may benefit from more frequent sealing.

Tip: A quick way to check if your brick needs resealing — sprinkle water on the surface. If it soaks in immediately instead of beading up, it’s time for a new coat.

Which Type of Sealer Is Best for Brick?

Not all sealers are created equal. The right type depends on your brick and desired finish:

• Penetrating Sealers: Soak deep into the brick to protect from within — ideal for driveways and walkways that need slip resistance.
• Film-Forming Sealers: Create a glossy surface layer that enhances color and provides added protection.
• Silane/Siloxane Sealers: Long-lasting and breathable, these are excellent for Tennessee’s climate.

At Brick Mason Nashville, we typically recommend penetrating siloxane-based sealers for outdoor brick — they protect without altering the natural look.

Signs It’s Time to Reseal Your Brick Driveway or Walkway

If you notice any of the following, your brick is likely overdue for sealing:

• Dull or faded color
• Powdery white residue (efflorescence)
• Cracked or loose mortar
• Water soaking into the surface instead of beading
• Moss or mildew growth

Catching these signs early can prevent costly masonry repairs later on.

The Cost of Brick Sealing in Nashville

The cost to professionally seal a brick driveway or walkway typically ranges from $1.50 to $3.50 per square foot, depending on surface condition, product type, and accessibility.

For most homeowners, the total investment is a fraction of what repairs or brick replacement would cost down the line.
