Sealing Cracks in Your Concrete Driveway: DIY vs. Call a Pro

Sealing Cracks in Your Concrete Driveway: Should you DIY or Call a Pro?

In Ohio, driveway cracks are inevitable—but expensive damage isn’t.
If the crack is small and stable, you can fix it yourself. If it’s wide, deep, or shifting, call a pro before it turns into a replacement.


1. Why Driveway Cracks Happen (and Get Worse Fast in Ohio)

Concrete fails the same way every year here:

  • Freeze–thaw cycles force cracks open

  • Salt accelerates surface breakdown

  • Water gets underneath → expansion, heaving, spalling

  • Heavy vehicles stress weak spots

Not all cracks are equal:

  • Hairline = cosmetic, manageable

  • Wide / uneven = structural, risky

👉 Ignore them, and they spread—fast.


2. DIY Crack Repair: When It Actually Works

You’re good to handle it yourself if:

  • Cracks are under ¼ inch

  • No vertical movement (not uneven)

  • Damage is isolated

Best options:

  • Liquid crack sealer (hairline) Check out this how-video!

  • Caulk-style filler (most common)

  • Patching compound (slightly larger cracks)

Non-negotiable step:
Clean + dry the crack first.
If not, the repair fails—guaranteed.


3. When to Call a Pro (and Protect It the Right Way)

Bring in a pro if you see:

  • Cracks wider than ¼ inch

  • Sinking, lifting, or uneven slabs

  • Deep or spreading cracks

  • Multiple crack patterns across the driveway

These usually need levelling, stabilisation, or more than basic filler.

Then—don’t stop at repair.

👉 The real move is wash + seal after crack repair:

  • Removes salt, grime, and buildup

  • Seals concrete pores against water intrusion

  • Slows future cracking and surface damage

At Pristine Clean, we help homeowners lock in that protection with professional concrete cleaning and sealing—so you’re not fixing the same cracks every year.
