Asphalt Sealcoating Services
Protect and preserve your pavement investment with professional sealcoating
Noble Cortes General Engineering provides professional asphalt sealcoating across Northern California for parking lots, driveways, private roads, and sports courts. We seal, protect, and restore your pavement with commercial-grade materials and a full-prep application process that extends pavement life and keeps your property looking its best.
What Is Asphalt Sealcoating?
Asphalt sealcoating is a protective coating applied over existing asphalt pavement. A thin layer of sealer, asphalt emulsion, coal tar, or a polymer-modified blend, is sprayed or squeegeed across the surface to seal out water, UV, and chemicals, restore a deep black finish, and extend pavement life for a fraction of the cost of resurfacing.
Extend Pavement Life with Professional Sealcoating
Your asphalt surfaces represent a significant investment in your property’s infrastructure. Without proper protection, even the best-installed pavement will deteriorate prematurely due to weather exposure, UV radiation, and chemical damage—leading to costly repairs and premature replacement.
Professional sealcoating creates a protective barrier that shields your asphalt from these damaging elements, extending pavement life while restoring a rich, black appearance that enhances your property’s curb appeal. At Noble Cortes General Engineering, we deliver expert sealcoating services that protect your investment and maximize the return on your infrastructure dollars.
Our approach to sealcoating goes beyond simply spraying material on your pavement. We employ a comprehensive process that addresses existing conditions, ensures proper application, and provides long-lasting protection—delivering superior results compared to basic maintenance providers.
Professional sealcoating serves multiple protective functions:
- UV Protection – Acts as “sunscreen” for your pavement, preventing ultraviolet rays from accelerating oxidation
- Water Barrier – Creates a water-resistant seal that prevents moisture penetration into the pavement structure
- Chemical Shield – Protects against automotive fluids, deicing chemicals, and other substances that break down asphalt binders
- Surface Restoration – Fills minor surface voids while restoring rich black color and improving texture
When applied at the optimal time and with proper techniques, sealcoating can extend asphalt life by 25-30% or more—representing substantial savings over premature rehabilitation or replacement.
Our Asphalt Sealcoating Services
Noble Cortes provides two core sealcoating services, matched to whether your pavement is being sealed for the first time or maintained on a cycle.
New Asphalt Sealcoating
The first protective coat for new or unsealed pavement, applied once it has cured. We apply two coats to build a full protective layer.
- Surface cleaning and oil-spot priming
- Two-coat sealcoat application
- Fresh line striping layout
Asphalt Resealing
The maintenance recoat of previously sealed pavement, typically every 2 to 3 years. Sound lots take a single coat; worn lots get crack and patch repair first.
- Cleaning, crack filling, and minor patching
- Single-coat recoating application
- Restriping of faded markings
The Noble Cortes Sealcoating Advantage
Many providers offer basic sealcoating as a low-cost service with minimal preparation and generic materials. Our comprehensive approach delivers superior results through four key differentiators:
Expert Assessment & Preparation
We begin with thorough pavement evaluation to identify underlying issues and analyze traffic patterns. Our preparation process includes professional cleaning beyond simple air blowing, oil spot treatment for proper adhesion, crack sealing of damaged areas, and proper masking of adjacent surfaces.
Premium Materials & Application
Our application process uses commercial-grade sealcoat materials with enhanced durability, proper dilution and additive mixing for specific site conditions, and consistent techniques for uniform coverage. Multiple coat strategies for high-traffic areas ensure appropriate curing time before reopening to traffic.
When Your Property Needs Sealcoating
The ideal timing for sealcoating application is before significant damage occurs. Consider this protective maintenance when you notice these indicators:
- Your asphalt shows signs of fading from deep black to gray
- The pavement reaches 1-2 years of age for new installations
- It’s been 3-5 years since the last sealcoat application
- Surfaces appear dry with developing cracks
- Increased surface raveling with loose aggregate
- Before harsh seasonal conditions (winter freezing or summer heat)
Proactive sealcoating is significantly more cost-effective than waiting until pavement requires major repairs. Our assessment process helps determine the optimal timing for your specific pavement conditions.
Our Professional Sealcoating Process
We approach each sealcoating project with our signature Noble Cortes Advantage™, ensuring consistent quality and superior results:
- Comprehensive evaluation of pavement condition and usage patterns
- Thorough surface preparation including cleaning, oil treatment, and crack sealing
- Material selection and customization based on specific site conditions
- Professional application using appropriate equipment and techniques
- Controlled curing and finishing with proper traffic control until fully cured
This systematic approach ensures optimal sealcoat performance and maximum protection for your pavement investment.
Application Methods
We apply a sealcoat by spray, squeegee, or both, based on your pavement’s condition.
- Spray sealing. Fast, even coverage on large lots.
- Squeegee sealcoating. Works sealer into the pores for adhesion.
- Spray and squeegee. Squeegee coat for bond, spray coat for finish.
Premium Sealcoating Materials
We utilize only commercial-grade sealcoating materials engineered for professional application:
Asphalt Emulsion Sealers
Water-based formulations that provide excellent UV protection and water resistance with minimal environmental impact. These sealers are ideal for most residential and commercial applications, offering 3-5 years of protection with proper application.
Coal Tar Sealers
Traditional sealers offering superior fuel and chemical resistance, making them appropriate for gas stations and industrial facilities where permitted by local regulations. These provide enhanced durability in high-exposure environments.
Modified Polymer Sealers
Premium sealcoating materials enhanced with latex or acrylic polymers for improved flexibility and longevity. These advanced formulations provide superior performance in challenging conditions and high-traffic applications.
Each material is selected based on your specific needs, local regulations, and environmental considerations to provide optimal protection for your pavement.
How Much Does Asphalt Sealcoating Cost in Northern California?
Asphalt sealcoating typically runs $0.15 to $0.50 per square foot for a standard application, and $1.25 to $1.50 per square foot when bundled with heavy prep and repairs. Commercial parking lots average $0.17 to $0.40 per square foot.
Scope | Typical range |
Standard sealcoat application | $0.15 – $0.50 / sq ft |

Frequently Asked Questions
Is sealcoating worth it, or can we skip it?
Yes, sealcoating is worth it because it extends asphalt life by up to 50% percent by blocking water, UV, and chemicals.
What happens if we do not sealcoat, and are there downsides to doing it?
If you do not sealcoat, asphalt oxidizes, grays, and cracks, leading to costly repairs or early replacement. The only real downside is a short closure while it cures. Done correctly and on schedule, the benefits far outweigh it.
Is it better to spray or squeegee sealcoat?
Both work. Use squeegee for the first coat on worn or porous asphalt for a stronger bond, and spray for fast, even finish coats. Many jobs combine them: squeegee for adhesion, spray for finish.
Is sealing your blacktop driveway pointless?
No, not when it’s timed right. Sealing sound pavement every 2 to 3 years protects it from UV and water. It only wastes money on uncured new asphalt, unrepaired cracks or potholes, or pavement that is already failing structurally, which needs patching or an overlay instead.
What time of year is best to seal a driveway?
The best time of the year to seal a driveway is late spring (May – June) through early fall (September – October). Temperatures hold between 50 and 85 degrees with a 24 to 48 hour dry window. Avoid winter rain and peak-summer heat above 85 degrees.
