Professional Asphalt Protection And Pavement Preservation Across The Pacific Northwest
Well-maintained pavement plays an important role in safety, appearance, and long-term property value. Commercial parking lots, municipal roads, recreational courts, and private facilities across the Pacific Northwest experience constant wear from traffic, moisture, seasonal temperature changes, and environmental exposure. Without proper maintenance, asphalt surfaces gradually develop cracks, fading markings, potholes, and structural deterioration that reduce functionality and increase repair costs over time. At All Seal, asphalt maintenance is approached as a proactive strategy rather than a reactive repair process. Surfaces are carefully evaluated before selecting appropriate treatments such as sealcoating, crack sealing, pavement markings, and striping. With 8 years of hands-on industry experience, professional asphalt solutions are delivered using durable materials, efficient installation methods, and precise workmanship.

What we do
SEALCOATING
Sealcoating protects asphalt from oxidation, moisture intrusion, and damaging ultraviolet exposure that gradually weakens pavement surfaces. Applying a protective sealant restores rich black appearance while forming a barrier against vehicle fluids, harsh weather, and everyday traffic wear.STRIPING
Clear parking lot striping improves organization, safety, and traffic flow for vehicles and pedestrians. Precise striping creates defined parking spaces, directional arrows, fire lanes, and accessible areas while durable traffic paints maintain strong visibility and support compliance.STREET SIGNS
Street sign installation strengthens navigation and traffic management across parking areas and roadways. Signs provide clear instructions guiding drivers and pedestrians while reflective materials improve visibility during both daytime and nighttime conditions, supporting consistent and safe traffic control.ASPHALT MAINTENANCE
Asphalt maintenance preserves pavement strength through preventative care and targeted surface repairs. Routine inspections identify early damage before deterioration spreads, while maintenance treatments restore smoother driving conditions, prevent structural weakening, and extend the lifespan of paved surfaces.PAVEMENT MAINTENANCE
Pavement maintenance combines preventative treatments and minor repairs that keep surfaces durable and organized. Addressing cracks, wear, and fading markings reduces water infiltration risks while preserving structural integrity and ensuring safe movement for vehicles and pedestrians.PAVEMENT MARKINGS
Pavement markings provide visual guidance that organizes traffic movement and pedestrian navigation. Directional arrows, crosswalks, stop bars, and specialty markings improve safety in busy areas while durable materials maintain visibility despite heavy traffic and changing weather.CRACK SEALING
Crack sealing prevents water from penetrating asphalt layers where structural damage begins. Flexible rubberized sealant fills surface cracks, blocking moisture and debris while adapting to temperature expansion and contraction, slowing deterioration and protecting pavement from costly repairs.THERMOPLASTICS
Thermoplastic pavement markings deliver highly visible, long-lasting traffic markings for high-use areas. Heated thermoplastic materials bond firmly with asphalt surfaces, creating durable symbols and lines that resist fading, abrasion, and weather exposure while maintaining excellent visibility.SPORTS COURTS
Sports court striping creates precise playing boundaries for basketball, tennis, pickleball, and recreational courts. Accurate layouts and durable coatings produce vibrant lines that remain visible through frequent use, helping schools, parks, and community facilities maintain safe play areas.MINOR PATCH WORK
Minor patch work repairs localized asphalt damage before it spreads into larger pavement failures. Fixing small potholes, depressions, and worn sections restores smoother driving conditions while preserving pavement integrity and preventing the need for extensive resurfacing projects.What our customers have to say...

FREQUENTLY ASKED QUESTIONS
How often should asphalt parking lots be sealcoated?
Most commercial parking lots benefit from sealcoating every two to three years depending on traffic levels and weather exposure. Routine sealcoating protects asphalt from oxidation, moisture intrusion, and vehicle fluids.
What types of properties typically require pavement striping?
Parking lots, schools, hospitals, apartment complexes, shopping centers, and municipal facilities commonly require pavement striping. Clear layouts, directional arrows, fire lanes, and accessible spaces help maintain organized traffic movement.
Does crack sealing really prevent larger pavement damage?
Yes. Crack sealing blocks water from entering asphalt layers where structural damage begins. Sealing cracks early prevents moisture infiltration, reducing freeze-thaw damage and helping protect pavement structure from costly deterioration.
