Since 2001, our team has offered asphalt sealcoating (and other pavement repair and maintenance) services to customers in New Jersey, Pennsylvania, Delaware & Maryland. If there's one thing we know well, it's asphalt!

Asphalt has a number of enemies. You know, things like extreme heat, extreme cold, oxidation, gasoline and other oils, and more.
Property managers sealcoat their driveways, parking lots, and other asphalt surfaces for protection! Sealcoating your asphalt is like equipping it with battle armor.
Protecting your asphalt with high-quality sealcoating offers property managers a number of benefits.
Periodic asphalt maintentenance can extend the life of your asphalt up to 30 years. When new asphalt is properly sealcoated within the first year, the surface will experience much less degradation from water, traffic, and UV damage from the sun. Sealcoating also protects against oxidation caused by harsh weather like heavy rain, snow, and ice.
Sealcoating can save property managers a significant amount of money as well. While many are reluctant to spend more up front on premium grade pavement sealers, in the video below you'll see how it actually costs less when amortized over a 12-year period.
Two more sealcoating benefits:
A quick note on what sealcoating WON'T do--sealcoating an asphalt parking lot that's been neglected for 10-15 years is like putting a small band-aid on a severe wound. You know, the kind that needs stitches. It may look fine for a short while, but there won't be any structural value or real protection happening.
Unfortunately, this happens far too often with sub-par contractors. They claim sealcoating will extend the life of your deteriorating asphalt lot a couple of years, when what you may really need is full-on pavement reconstruction, not just a pretty black coat. Sealcoating doesn't resurface asphalt, and it doesn't level or fix low spots.
Like different grades of fine wine, the sealcoating industry has it's own "house list," with more than a dozen different mix formulas used in a variety of ways:
Of course, there are many sub-types and caveats with the above list. Many more green, bio-based rejuvenators exist these days than used to.
There are also fast-dry pavement sealers that can be ready for traffic in as little as one hour--great for quick-service restaurants, hospitals, airport taxiways, shopping centers, or any other high-volume parking lot that can't be shut down for 24 hours.
One thing to note is that sealcoats are different than Type I, II & III slurry seals / microsurfacing, which all use a much coarser aggregate filler and are designed for use on high speed areas with straight rolling traffic.
I should mention that Coal Tar Emulsion Sealer is banned in some U.S. states due to environmental concerns. This trend toward environmentally friendly alternatives is likely to continue, something I can certainly stand behind!
So, how is sealcoat applied?
Sealcoat is applied directly onto the surface of a (recently cleaned) asphalt pavement. It can be applied using rubber squeegees, brooms, or mechanical spray, often a combination of the aforementioned applications. An example here would be that the first coat of sealcoat is applied via squeegee, and the second coat is applied by spray.
When it comes to Asphalt Emulsion Sealer, we like squeegees and think they offer the best re: durability.
Most jobs take two coats, which requires 24-48 hours of curing before vehicles are allowed back onto the surface.
Before a sealcoating job, the asphalt should be cleaned using sweeping methods and/or blowers. An unclean surface could cause poor adhesion.
Once the surface is clean, the sealcoat mix is applied at about 60 square feet per gallon per coat.
Using Coal Tar or Asphalt Emulsion Sealer, the average price to sealcoat your asphalt surface ranges from $0.14 - $0.25 per square foot. A number of factors can affect the sealcoating price:
With the rising cost of Coal Tar and Asphalt Emulsion raw materials, fuel, insurance rates etc., if you are receiving prices for sealcoating under $0.14 square feet / $1.26 square yard, you are most likely going to receive a sub-standard project when complete.
How can a contractor cut corners? Here are a few ways:
A parking lot preventative maintenance plan (PMP), which involves sealcoating and hot rubberized crack sealing, is the ABSOLUTE best investment a property or facility manager can make. $0.25 cents per square foot spent TODAY will save $4.00 - $5.00 per square foot 10–15 years from now.
Proper timing of seal coating will enable you to extend the life of the asphalt by 300%. By seal coating within 12-18 months after asphalt installation, you will seal in the essential binder of the hot mix asphalt which is the glue that holds the stone and sand together for a smooth asphalt surface that is easy to sweep and will aid in melting snow and ice faster.
“Ok, I seal coated the parking lot 12 months after it was paved, everything should be okay now, correct?”
Would you buy a new car with a perfect metallic paint finish, wax it one time and then never wax it again? Probably not.
Seal coating should be scheduled on a 3-5 year rotation.
The below video showcases our unique, consultative approach to sealcoating projects.
Since 2001, our company has put down millions of gallons of pavement sealer is committed to providing you with not only the highest quality workmanship in the industry, but straightforward recommendations of the proper applications for your specific project.
95% of sealcoating / pavement maintenance contractors are not providing quality work or long-lasting product application. Our parking lot consultants are trained to help property managers identify these inferior applications. We do this by encouraging them to contact the manufacturer or certain cooperative distributors to ascertain how the bidding contractor mixes their pavement sealer. They find, 7 times out of 10, the contractor is mixing the concentrate sealer with only water. To add insult to injury, water dilution ratios far exceed what the manufacturer’s recommendations!
We're also the most technologically advanced asphalt & concrete contractor in the Mid-Atlantic Market (New Jersey, Pennsylvania, Delaware & Maryland). We provide everything from a dedicated video channel with live drone videos of your project in progress to daily work-in-progress pictures, all uploaded into your dedicated client portal.
