Protect Your Asphalt Investment with Professional Sealcoating

Whether you own a residential driveway, commercial parking lot, HOA, apartment complex, industrial facility, or retail property, your asphalt is one of the first things customers, tenants, and visitors notice. At GPG Sealcoat & Striping, we provide professional asphalt sealcoating services throughout Oregon and Washington that help protect your pavement from the harsh Pacific Northwest climate while restoring a clean, jet-black appearance. Over 20 years of industry experience aids our licensed, bonded, and insured crews to service your investment with care.

Asphalt is a major investment. Without regular maintenance, it begins deteriorating from the day it is installed. Our professional sealcoating services are designed to slow that deterioration, reduce long-term repair costs, and maximize the life of your pavement.

What Is Asphalt Sealcoating?

Sealcoating is a protective surface treatment applied over existing asphalt pavement. The coating forms a durable barrier that shields the asphalt from oxidation, moisture intrusion, ultraviolet (UV) radiation, automotive fluids, road salts, and everyday vehicle traffic.

Unlike asphalt replacement, sealcoating is preventative maintenance. It does not repair structural failures, but it significantly slows the aging process that eventually leads to cracking, potholes, raveling, and pavement failure.

Think of sealcoating as sunscreen for your pavement—it protects the asphalt binder from breaking down under constant exposure to the elements.

Why Sealcoating Is Especially Important in Oregon & Washington:

The Pacific Northwest presents unique challenges for asphalt pavement.

Heavy rainfall, standing water, freezing temperatures in many areas, moss growth, UV exposure during the summer months, and constant moisture all contribute to premature pavement deterioration.

Without proper protection, water can penetrate small cracks in the pavement where freeze-thaw cycles expand the damage beneath the surface. Over time, this leads to cracking, potholes, base failure, and costly reconstruction.

Professional sealcoating helps reduce these risks by providing a protective barrier that slows water penetration and shields the asphalt from weather-related damage.

For property owners throughout Oregon and Washington, routine pavement maintenance is one of the most cost-effective investments you can make.

Our Professional Sealcoating Process:

At GPG Sealcoat & Striping, we believe that proper preparation is what separates an average sealcoating job from one that provides years of protection.

Every project begins with a detailed evaluation of your pavement to determine its condition and identify any repairs that should be completed before sealing.

Our process typically includes:

• Complete cleaning of the pavement using commercial blowers, sweepers, and debris removal equipment
• Removal of weeds, moss, dirt, and loose aggregate
• Oil spot treatment to improve sealer adhesion
• Crack sealing and minor asphalt repairs when needed
• Protection of concrete surfaces, buildings, landscaping, and curbing
• Professional application of premium commercial-grade asphalt sealer using spray systems and detail brushes for uniform coverage
• Final inspection to ensure complete coverage and quality workmanship
• Barricading and curing protection until the pavement is ready for vehicle and pedestrian traffic

We never cut corners during preparation because proper surface preparation is the foundation of a long-lasting sealcoat application.

Benefits of Professional Asphalt Sealcoating:

Routine sealcoating offers significant long-term benefits for both residential and commercial property owners.

Extends Pavement Life

Sealcoating slows oxidation and weathering, helping asphalt remain flexible and reducing premature cracking. Properly maintained asphalt can often last 25–30 years or more, while neglected pavement may require major repairs much sooner.

Protects Against Water Damage

Moisture is one of asphalt's greatest enemies. Sealcoating helps reduce water penetration that can weaken the pavement base and accelerate deterioration.

Prevents UV Damage

Sunlight causes asphalt oils to evaporate over time, leaving pavement brittle and prone to cracking. Sealcoating helps protect against harmful ultraviolet rays that accelerate aging.

Resists Oil & Chemical Damage

Gasoline, diesel fuel, motor oil, hydraulic fluid, antifreeze, and other automotive chemicals soften asphalt and shorten its lifespan. A quality sealcoat provides added resistance against these contaminants.

Improves Appearance

Fresh sealcoating restores asphalt's rich black color, dramatically improving curb appeal and creating a professional appearance for businesses, apartment complexes, and residential properties.

Enhances Parking Lot Striping

Fresh pavement markings adhere better and remain more visible when applied over properly sealed pavement, improving safety, traffic flow, and ADA compliance.

Saves Money

Routine sealcoating costs only a fraction of major asphalt repairs or complete pavement replacement. Preventative maintenance protects your investment while reducing long-term ownership costs.

How Often Should Asphalt Be Sealcoated?

Most asphalt surfaces should be professionally sealcoated every 2 to 4 years, depending on traffic volume, weather exposure, drainage, and pavement condition.

Typical recommendations include:

• Residential driveways: every 2–3 years
• Commercial parking lots: every 2–4 years
• HOA communities: every 2–3 years
• Industrial properties: based on traffic volume and wear

Regular inspections allow maintenance to be scheduled before minor issues become expensive structural repairs.

How Long Does Sealcoating Last?

A professionally installed commercial-grade sealcoat typically provides protection for approximately 24 to 48 months under normal conditions.

Factors that affect longevity include:

• Vehicle traffic
• Heavy truck use
• Weather exposure
• Drainage conditions
• Snow removal practices
• Pavement age
• Surface preparation

Proper maintenance, crack sealing, and periodic reapplication significantly extend the life of both the sealcoat and the asphalt beneath it.
