How to Repair Cracks in Concrete and Masonry Walls: A Step-by-Step Guide

Seeing cracks in your walls is never a good time. But before you panic and imagine your home crumbling to the ground, take a deep breath. Small cracks are common and fixable! Whether you’re dealing with hairline fractures or something a bit more intimidating, concrete crack repair can be tackled with the right approach (and sometimes a pro). Here’s a fun, no-stress guide to help you get started!

Step 1: Know When to Worry

Not all cracks are created equal. Hairline cracks? Pretty normal. Horizontal or widening cracks? Those may need urgent attention. Especially in areas prone to moisture, like basements, cracks can lead to major issues without proper concrete crack repair. That’s why hiring waterproofing contractors is key when in doubt.

Step 2: Clean the Crack

Start by removing any loose debris using a wire brush or a vacuum. If you skip this step, your repair materials won’t bond properly—and nobody wants a flaky fix.

Step 3: Choose Your Repair Method

For thin cracks, use a concrete crack filler or patching compound. For wider gaps, opt for epoxy or polyurethane injections for a lasting solution. If you’re dealing with old, historic masonry, it’s better to call in a stone repointing contractor, to ensure the repair blends with the original structure.

Step 4: Apply and Seal

Apply your filler with a caulking gun or putty knife, depending on the material. Smooth it out and let it cure per the product instructions. Don’t forget to seal the area to prevent moisture.
