Asphalt Seal & Repair – Providing Trusted Asphalt Services for Green Bay and Beyond

Asphalt Sealcoating Company Serving Green Bay & Surrounding Communities

Locally Trusted for Over 50 Years

If you own or manage a commercial property in Northeast Wisconsin, you know how quickly winter weather can wear down asphalt. Snow, road salt, moisture, and constant temperature swings all leave their mark. That is why many property owners in Green Bay rely on sealcoating to protect their surfaces and extend the life of their asphalt.

At Asphalt Seal & Repair, we’ve been providing dependable asphalt sealcoating in Green Bay and across Northeast Wisconsin for more than 50 years. Our team works with property owners and managers throughout the region to protect asphalt surfaces.

What Is Sealcoating?

Sealcoating is a preventative maintenance service we use to protect asphalt from moisture, sun exposure, and everyday wear. By applying a protective sealant to the pavement surface, we help block water, UV rays, chemicals, and oxidation that can gradually break down asphalt. Without that protection, the surface begins to dry out, small cracks form, and moisture can start working its way into the pavement.

In Green Bay and across Northeast Wisconsin, this wear can happen even faster due to long winters. Snow, ice, and road salt often sit on pavement for months, while freezing temperatures cause trapped moisture to expand as it freezes and thaws.

A properly applied sealcoat helps slow this process by sealing the surface and limiting water penetration. At Asphalt Seal & Repair, we use commercial-grade sealants from trusted manufacturers such as GemSeal and SealMaster to not only give your surface top-quality protection, but also restore that sleek, black finish that keeps asphalt looking striking.

Why Your Green Bay Property Needs Professional Sealcoating

Asphalt surfaces deal with a lot over the years, from heavy traffic to Wisconsin’s harsh winters. Sealcoating helps protect that pavement and slows the wear that eventually leads to larger repairs.

Extends Pavement Lifespan

Small cracks can appear long before pavement shows serious damage. If those cracks are ignored, water can seep into the asphalt and begin to weaken the pavement below. In Northeast Wisconsin, winter speeds up this process as trapped moisture freezes and expands.

Sealcoating helps protect the surface by reducing moisture exposure and slowing oxidation. When combined with routine crack sealing, it helps keep asphalt parking lots and roadways performing longer.

Protects Against Gas, Oil & Salt

Traffic isn’t the only thing that gives pavement trouble. Vehicles leave behind fuel, oil, and other fluids that can slowly wear down asphalt over time. Winter road salt can add even more stress to the pavement surface.

Sealcoating helps shield asphalt from these chemicals and keeps the surface in better condition through the changing seasons.

Halts UV Oxidation

Sunlight gradually dries out asphalt. As the natural oils break down, the pavement becomes more brittle and more likely to crack under traffic and temperature changes.

Sealcoating helps slow that process by protecting the surface from UV exposure and keeping the asphalt flexible.

Boosts Property Appearance

Sealcoating also gives commercial pavement a refreshed look. The dark, uniform finish helps parking lots look cleaner and more organized, especially good for business and property owners looking to make a great first impression on customers, tenants, or visitors.

Our 5-Step Sealcoating Process for Lasting Results

A quality sealcoating job starts well before the sealcoat goes down.
Our crew follows a proven process that prepares the pavement, addresses problem areas, and finishes with a clean, consistent seal designed to protect commercial asphalt surfaces.

Here is what we do:

Prepare & Clean

We begin by thoroughly cleaning the pavement surface. Dirt, debris, and loose material are removed to ensure the sealcoat bonds properly with the asphalt.

Seal & Patch

Existing pavement issues are addressed before sealcoating begins. Cracks are sealed to help prevent water intrusion, and damaged areas can be repaired using appropriate asphalt patching methods when needed.

Apply

Once the surface is ready, we apply commercial-grade sealant using professional equipment. Depending on the pavement’s layout, the material may be sprayed, brushed, or squeegeed to ensure consistent coverage.

Dry & Cure

After application, the sealcoat must properly cure before traffic returns to the surface. Weather conditions such as temperature and humidity can affect curing time, so we monitor the process closely and will let you know if there are any changes to the timeline.

Inspect

Before we consider the job done, our team performs a final inspection to confirm consistent coverage and a clean finish across the pavement.

Commercial Sealcoating in the Green Bay Area

Asphalt surfaces across Green Bay deal with steady use and long Wisconsin winters. Sealcoating helps keep those surfaces in good shape while maintaining a clean, uniform look across the property.

Commercial Parking Lot Sealcoating

Commercial parking lots see constant traffic throughout the year. Over time, that wear starts to show as fading, surface drying, and small cracks. Sealcoating helps property managers stay ahead of those issues by protecting the pavement as part of a proactive maintenance plan.

Most commercial lots in Northeast Wisconsin are sealcoated every 2 to 4 years, depending on traffic and winter conditions. Keeping up with that schedule helps maintain the surface and avoid larger pavement repairs later.

Frequently Asked Questions About Sealcoating

How do I know if my pavement needs sealcoating or full replacement?

If your pavement has surface-level cracking, fading, or minor wear, sealcoating is likely the right solution; it protects and restores the existing surface without the cost of full reconstruction. However, if you’re dealing with deep structural cracks, widespread potholes, or a failing base layer, sealcoating alone won’t solve the problem, and replacement or more extensive repair may be necessary. When in doubt, a professional inspection can help you determine the most cost-effective path forward.

What is the best time of year to invest in asphalt sealcoating in Green Bay?

We recommend scheduling asphalt sealcoating in Green Bay between late spring and early fall, with late summer to early fall being the ideal window. During this time, temperatures are warm enough for proper curing, and conditions are typically dry and stable, which helps the sealcoat perform at its best. Applying sealcoating before winter also protects your pavement from freeze-thaw cycles, moisture, and salt damage.

How frequently is pavement sealcoating required?

For most properties, sealcoating every few years keeps asphalt in good shape. Commercial parking lots may need it every 2 to 4 years, depending on traffic and winter conditions. Surfaces that see heavier use may benefit from a shorter maintenance cycle.

How long should we stay off freshly sealed asphalt?

In most cases, it’s best to stay off the pavement for at least 24 hours. On warm, dry days, the surface may cure faster, but shaded areas or humid conditions can slow things down. Giving the sealcoat enough time to fully cure helps prevent marks or damage to the new surface.

What do I need to do to prepare for sealcoating?

Preparation is usually simple. Move vehicles out of the area before the crew arrives and keep them off the pavement until the sealcoat has cured. If sprinklers run near the pavement, they should be turned off for about 24 hours before and after the project so the surface can dry properly.
