Behind the Scenes: How Seal It Up! Fixes Cracks Before They Spread

Cracks in asphalt might seem small at first — but left untreated, they grow fast. Between temperature swings, UV exposure, and everyday traffic, those tiny lines can turn into potholes or full-blown surface failure. At Seal It Up!, stopping cracks early is what we do best. Here’s a look behind the scenes at how our team repairs and restores pavement so it stays strong, smooth, and protected.

Why Cracks Form — and Why They Matter

Asphalt is designed to flex with changing temperatures, but over time, heat, sunlight, and heavy loads cause that flexibility to fade. When the surface dries out, it becomes brittle and begins to split.

Once a crack opens, water becomes the enemy. Moisture seeps beneath the surface, breaking down the base layers that support the pavement. The result? Larger cracks, potholes, and costly structural damage. Early intervention is key — and that’s where our repair process comes in.

Step 1: Inspecting and Cleaning the Cracks

Every repair begins with a detailed inspection. Our technicians check the depth, width, and pattern of the cracks to determine the best repair method. Different cracks call for different solutions — from fine surface splits to deep structural gaps.

Next, we thoroughly clean each crack. Using compressed air and high-powered blowers, we remove dirt, debris, and vegetation. A clean surface is critical; if filler is applied over dust or loose material, it won’t bond properly.

Step 2: Drying the Area Completely

Even in a dry climate, cracks can hold hidden moisture. If not removed, that moisture can weaken the sealant. Our crews use heat lances or drying tools to evaporate any remaining water, ensuring the area is completely dry before filling.

This step might not sound dramatic, but it makes all the difference — especially during early morning repairs when cooler air can trap humidity at the surface.

Step 3: Applying Professional-Grade Crack Filler

Once the cracks are prepped, we apply hot rubberized crack filler. This specialized material is designed to expand and contract with the pavement, sealing out moisture and debris while maintaining flexibility through changing temperatures.

The filler is heated to the manufacturer’s precise specifications, then carefully poured into the cleaned cracks. Our team smooths and levels the surface so it blends seamlessly with the existing pavement.

Step 4: Finishing Touches That Make Repairs Last

After filling, we allow the material to cool and set before reopening the surface. In some cases, we apply a light dusting of sand or fine aggregate to help prevent tracking and improve traction.

Finally, we inspect the area one last time to confirm a tight, durable seal. If the surrounding asphalt shows signs of aging, we may recommend sealcoating to protect the entire surface and slow future cracking.

The Seal It Up! Difference

Many property owners only see the finished surface — but our success comes from the precision and care behind the scenes. Every crack repair is handled with attention to detail, from the initial inspection to the final cleanup.

By addressing cracks early, we help extend pavement life, improve curb appeal, and prevent costly structural damage. It’s one of the smartest, most affordable ways to protect your investment.
