Why Seal Coat Your Driveway?
We’ve all seen the viral videos of guys with push-squeegees, spreading around black tar over driveways and roads. For once, what you see online is actually a good idea! Seal coating is a great way to protect and freshen up your parking surfaces and driveways.
Protects against water, UV, oil, and chemical damage that break down asphalt over time.
Extends driveway lifespan from roughly 7–10 years when neglected to 20–30 years with regular sealcoating and maintenance.
Saves money long term by delaying expensive repairs or full replacement that can cost many times more per square foot than sealcoating.
Improves curb appeal with a rich, uniform black finish that makes the whole property look cleaner and better maintained.
Think of seal coating like waxing your car: you’re adding a protective layer that keeps the structure underneath looking better and lasting longer.
Our Driveway Seal Coating Process
Inspection and prep
Assess existing asphalt condition, note cracks, oil spots, drainage issues, and prior coatings.
Block off the area and ensure safe access and clear communication with the homeowner.
Cleaning and crack repair
Power clean the surface to remove dirt, loose material, and debris for better adhesion.
Treat oil spots and fill cracks to help stop water infiltration into the base.
Professional sealant application
Apply commercial-grade asphalt sealer (squeegee, spray, or a combination) at the manufacturer’s recommended coverage rate.
Edge and detail around concrete, landscaping, and hard-to-reach areas for a clean, professional finish.
Dry time and final walkthrough
Typical residential driveways are ready for foot traffic in a few hours and vehicle traffic after 24–48 hours, depending on weather.
Walk the property with you to review the work and provide maintenance recommendations and next-service timing.
How Often Should You Seal Coat?
Most asphalt driveways benefit from seal coating every 2–3 years, depending on traffic, sun exposure, and previous maintenance.
New asphalt typically needs 6–12 months of curing before the first seal coat, then a regular schedule to keep it protected.
If your driveway looks gray, chalky, or shows fine cracking, it’s usually time for a fresh coat.
Driveway Seal Coating Pricing
Pricing is typically calculated per square foot, with variables like size, condition, and crack repair needs affecting the final investment.
Nationally, professional driveway sealing often ranges from a few hundred dollars for a small drive to the mid-hundreds for larger surfaces, while full replacement can cost many times more per square foot.
