Why Crack Sealing Is Essential
Crack sealing is one of the most important preventative maintenance steps you can take for asphalt surfaces. It keeps water from seeping into cracks and weakening the base layer, which can lead to potholes, heaving, and costly structural damage.
What Types of Cracks Can Be Sealed?
We seal a wide range of asphalt cracks, including block cracks, longitudinal cracks, transverse cracks, and edge cracks. Our team uses hot-applied rubberized sealants to ensure a flexible, weather-resistant bond that adapts to temperature changes.
Our Crack Sealing Process
We start by cleaning out the crack using pressurized air or mechanical tools. Then, we apply heated crack filler, ensuring it fills the space and bonds to the surrounding pavement. This prevents further water infiltration and extends the life of your surface.

Frequently Asked Questions
When is the best time to seal asphalt cracks?
Spring through early fall is ideal, when the weather is dry and temperatures are moderate. This allows the sealant to properly bond and cure.
How long does crack sealing last?
High-quality crack sealing can last 3–5 years depending on traffic and weather. Regular maintenance helps extend that lifespan.
Can I seal asphalt cracks myself?
DIY crack filler can provide short-term fixes, but professional crack sealing ensures deeper penetration, better adhesion, and longer-lasting results.
Is crack sealing only for older asphalt?
No. Even newer pavement can develop cracks due to freeze-thaw cycles, settling, or heavy loads. Sealing early protects your investment.
Will crack sealing affect the look of my pavement?
Sealed cracks are visible, but much less noticeable than potholes or crumbling edges. For the cleanest look, pair crack sealing with sealcoating.
