DIY Asphalt Sealcoating vs. Professional Application: Which Is Better?
For homeowners looking to protect and extend the life of their driveway, DIY asphalt sealcoating is often the first idea that comes to mind. It seems simple, affordable, and doable over a weekend. But how does it truly compare to hiring professionals for the job?
This blog breaks down the pros and cons of DIY asphalt sealcoating versus professional application, helping you make an informed decision that protects your investment.
What Is Asphalt Sealcoating?
Sealcoating involves applying a protective liquid layer over asphalt surfaces to guard against UV rays, water penetration, oil stains, and general wear. Without this layer, your driveway is exposed to the elements and more prone to cracks, potholes, and early failure.
If the surface has severe wear, sealcoating alone may not be enough. In such cases, a fresh asphalt paving job might be necessary to fully restore durability and appearance.
The DIY Approach: What It Entails
Doing DIY asphalt sealcoating means you’ll be taking on several steps yourself:
-
Clearing and cleaning the driveway thoroughly
-
Filling visible cracks with patching compound
-
Purchasing a store-grade asphalt sealant and application tools
-
Spreading the sealant with a squeegee or sprayer
-
Allowing at least 24–48 hours for curing
While the concept is straightforward, the execution can be tricky—especially for first-timers.
Advantages of DIY Asphalt Sealcoating
Lower Cost: A DIY kit with sealant and tools may cost between $100–$200 depending on driveway size.
Convenience: You can choose your schedule and work at your pace.
Sense of Accomplishment: If done well, it can be a satisfying project.
For those with prior experience or who enjoy hands-on work, DIY asphalt sealcoating might be a suitable option.
Disadvantages of DIY Asphalt Sealcoating
Despite its appeal, DIY comes with significant risks:
Shorter Lifespan: Store-bought products usually don’t last as long as commercial-grade products used by professionals.
Inconsistent Results: Uneven application, streaks, or missed cracks can lead to premature damage.
Time and Labor Intensive: Proper prep, application, and drying takes more time than expected.
No Warranty: If something goes wrong, you’re responsible for repairs.
Hiring professionals ensures high-quality asphalt sealant is applied using proper equipment and technique.
Why Choose a Professional?
Professional contractors bring years of experience and the right tools to ensure your driveway is sealed evenly and effectively. Here’s what you can expect from a pro:
-
Thorough prep: Pressure washing, crack filling, and proper drying before application
-
Efficient process: Most jobs completed in a single day
-
Superior materials: Commercial-grade asphalt sealant that lasts up to 3 years
-
Warranty coverage: Many professionals back their work for peace of mind
Professionals also know when asphalt paving is necessary rather than just sealing, ensuring long-term performance.
Long-Term Value Comparison
While DIY asphalt sealcoating saves money upfront, a poorly applied seal may only last one year. Professional work may cost more initially, but it lasts longer, looks better, and protects your driveway more effectively.
