Asphalt Sealcoating
At Rock County Sealcoat, we specialize in professional asphalt sealcoating and repair services, protecting and enhancing the value of your driveways and parking lots in Janesville, WI and surrounding areas.
What is Asphalt Sealcoating?
Asphalt sealcoating is the process of applying a protective liquid coating to the surface of your driveway or parking lot. This emulsion forms a durable barrier, shielding your asphalt from water, oil, UV rays, and harsh weather conditions. Without sealcoating, the asphalt deteriorates more quickly, developing cracks, becoming brittle, and leading to costly repairs or replacements.
The Asphalt Sealcoating Process
- Cleaning: We begin by thoroughly cleaning the asphalt surface. This involves edging the asphalt, removing dirt, and clearing out weeds from cracks using power edgers. We also pre-seal oil spots and blow away any remaining debris with power blowers.
- Crack Repair: Next, we address all cracking in the surface. We offer standard crack filling using hot-pour rubberized sealant, as well as crack routing, a more thorough process that mechanically widens and cleans the crack channel before sealing. The appropriate method is selected based on the size, severity, and history of the cracking.
- Sealcoat Application:Once the surface is prepared, we apply Pitch Black®, a premium rubberized asphalt emulsion sealcoat blended with select minerals, polymers, and chemicals. Pitch Black® has been in the industry for nearly 30 years, with hundreds of millions of square feet sealed nationwide. It delivers a deep, lasting jet-black finish with the firmest body and greatest durability available in the market. Its expansion and contraction coefficient matches asphalt pavement exactly, creating a natural bond that holds through Wisconsin’s freeze-thaw cycles. Pitch Black® is non-toxic, asbestos-free, contains no carcinogens, and is environmentally friendly. Because it dries quickly, line striping can be completed the same day as sealing, minimizing downtime for commercial properties. We apply Pitch Black® using commercial spray equipment, professional squeegees, or a combination of both. Single and double coat options are available, selected based on the surface’s age, condition, and traffic demands.
- Optional Line Striping: For commercial projects, we also provide parking lot striping, including lines, arrows, and handicap stall markings.
Why We Use Pitch Black®
Not all sealcoats are created equal. Rock County Sealcoat exclusively uses Pitch Black® — a premium rubberized asphalt emulsion that has earned its reputation over nearly 30 years and hundreds of millions of square feet of pavement sealed nationwide.
Here’s why Pitch Black® outperforms the competition:
- Deep, Lasting Black Color: Pitch Black® maintains a rich, jet-black finish — it does not fade to a blue or grey tint like coal tar products. What you see on day one is what your pavement looks like after a full Wisconsin winter.
- Superior Bond: Pitch Black®’s expansion and contraction coefficient matches asphalt pavement exactly, creating a natural affinity that holds through freeze-thaw cycles — no cracking, no separation.
- Same-Day Striping: Pitch Black® dries quickly, allowing line striping to be completed the same day as sealing. Less downtime for your property. Faster project completion.
- Compatible with All Striping Paint: Unlike coal tar, Pitch Black® is compatible with both water-based and oil-based striping paint — eliminating the stripe fading and adhesion issues that plague coal tar applications.
When Should You Sealcoat?
We recommend sealcoating every two to three years, depending on the climate and traffic levels. If the stones in your asphalt are visible, it’s time for a new application. The best time to sealcoat is between May and October, when temperatures are consistently above 60°F.

Frequently Asked Questions
How often should I have my asphalt sealcoated?
We recommend sealcoating your driveway or parking lot every two to three years. This frequency can vary based on your local climate and the level of traffic the surface receives. A good rule of thumb is to look at the asphalt: if the individual stones are becoming visible, it is time for a new application to protect the binder.
When is the best time of year to schedule asphalt sealcoating?
The ideal window for sealcoating in Wisconsin is between May and October. For the sealant to bond and cure properly, temperatures need to be consistently above 60°F. Scheduling during these warmer months ensures a durable, professional finish that will withstand the winter ahead.
What steps are involved in your asphalt sealcoating process?
- Crack Repair: We fill cracks with hot-pour rubberized sealant. For more severe cracking, we offer crack routing, a more thorough process that mechanically cleans and widens the crack channel for a longer-lasting repair.
- Application: We apply Pitch Black®, a premium rubberized asphalt emulsion sealcoat with nearly 30 years in the industry. It delivers a deep, lasting jet-black finish, matches asphalt’s expansion/contraction coefficient for a natural bond, and is non-toxic, asbestos-free, and environmentally friendly. Available in single or double coat, applied via commercial spray equipment, squeegee, or both. Dries quickly, and line striping can be completed the same day.
