Rock County Sealcoat
Asphalt Sealing
Every Rock County Sealcoat job follows the same proven process, whether we’re maintaining a residential driveway or a large commercial parking lot.
We begin with a thorough asphalt cleaning: edging the surface, clearing vegetation from cracks, treating oil spots, and power-blowing the entire area clean. A properly prepared surface is the foundation of a long-lasting seal.
Next, we address all cracks. We offer both standard crack filling using hot-pour rubberized sealant and crack routing, a more thorough process that mechanically widens and cleans the crack channel before sealing, resulting in a stronger, longer-lasting repair.
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 used for nearly 30 years and has been applied to hundreds of millions of square feet of pavement nationwide. It produces a deep jet-black finish with the firmest body and greatest durability available in the market. Its expansion and contraction coefficient matches asphalt exactly, ensuring 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, making it the ideal choice for school districts, healthcare facilities, and commercial properties. Because it dries quickly, line striping can be completed the same day as sealing.
We apply Pitch Black® using commercial spray equipment, professional squeegees, or a combination of both, depending on the size, age, and condition of the surface. Single and double coat options are available.
For commercial parking lots, we coordinate professional line striping, including standard stalls, directional arrows, ADA-compliant handicap markings, fire lanes, and custom layouts.

Why Sealcoat Asphalt?
Sealcoating your asphalt is an investment in your property. Sealcoating automatically increases the value of your property the same way remodeling, new additions, landscaping, or painting does. Put simply, it increases curb appeal and extends the usable life of your asphalt.
If you don’t sealcoat, your driveway or parking lot can appear gray and dull, which isn’t easy on the eyes. Regularly scheduled asphalt maintenance makes a huge difference. Also, when you’ve got a smooth surface, it makes cleaning it quicker and easier. A nice smooth black surface also helps snow and ice melt off your lot faster; a well-maintained asphalt surface is easier to clean and reduces overall maintenance costs over time.
Sun, rain, and snow can and will deteriorate driveways and parking lots over time. Sealcoating prevents oxidation and drastically slows down the deterioration of asphalt, ensuring that your driveway or parking lot not only looks good, but lasts longer and saves you money in the long run.

When To Sealcoat Your Asphalt
It is recommended that you sealcoat your driveway or parking lot every 2-3 years, a general rule of thumb is that if you can see the color of the stones that make up the asphalt, it is time to sealcoat it. The best time of year to sealcoat your surface is May-October, with the optimal temperature being 60 degrees or above. It’s also worth noting that you shouldn’t touch or drive on a recently sealcoated surface for 24 hours after completion.
