Professional Asphalt Sealcoating & Crack Filling Services

Asphalt sealcoating is a protective layer applied over your pavement to restore its rich, black finish and shield it from damage. While many people love the fresh, jet-black look of newly installed asphalt, sealcoating does much more than improve appearance. It creates a protective barrier against moisture, UV rays, oil spills, oxidation, and daily traffic wear. Without sealcoating, asphalt can dry out, fade, crack, and deteriorate more quickly — especially in Wisconsin’s harsh freeze-thaw climate. Regular sealcoating helps extend the life of your driveway or parking lot while keeping it looking clean and well-maintained.

Crack filling (also called crack sealing) is a preventative asphalt maintenance service where we apply a professional-grade, rubberized sealant into cracks in your pavement. This flexible material helps block water from penetrating beneath the surface.

In Wisconsin’s freeze-thaw climate, water intrusion is one of the leading causes of pavement failure. When water seeps into cracks and freezes, it expands — causing cracks to widen and eventually turn into potholes.

By sealing cracks early, you:

• Prevent moisture damage

• Slow the deterioration process

• Reinforce the structural integrity of the asphalt

• Extend the life of your driveway or parking lot

• Reduce the need for costly repairs later

Routine crack sealing is one of the most cost-effective ways to protect your asphalt investment and maintain a safe, durable surface.

For optimal protection, we recommend applying the first sealcoat about one year after new asphalt installation. After that, sealcoating should generally be done every 2–3 years, depending on traffic, weather exposure, and the condition of the existing sealer.

It’s important to avoid over-sealing, as applying sealcoat too frequently can trap moisture and reduce the effectiveness of the asphalt surface. Proper timing ensures your pavement stays protected, looks great, and lasts as long as possible.

Oxidation is a natural process that causes asphalt to fade from its rich black color and become more brittle over time. As the asphalt loses its flexibility, it becomes more prone to cracking and surface damage. While you can’t stop oxidation entirely, regular sealcoating creates a protective barrier that slows this process, helping your pavement maintain its appearance, strength, and durability for years.
