Asphalt Crack Sealing Services
Preventative maintenance that protects your pavement investment
Noble Cortes provides professional asphalt crack sealing services across Northern California, sealing cracks with hot-pour rubberized and cold-pour sealants before they spread into potholes and cause base failure. We clean, prep, and seal every crack to keep water out and extend your pavement’s life for a fraction of the cost of repair.
What Is Asphalt Crack Sealing?
Asphalt crack sealing is a preventative asphalt pavement treatment that fills and seals cracks with a flexible sealant to block water from reaching the base. It stops small cracks from spreading into potholes, alligator cracking, and structural failure, which makes it the most cost-effective step in pavement maintenance.
The Critical Importance of Timely Crack Sealing
Professional crack sealing delivers exceptional return on investment when performed at the right time:
Sealing a $20 crack today prevents a $150 pothole repair next year and a $450 rehabilitation cost down the road. This simple maintenance step typically extends pavement life by 3-5 years when properly executed.
Our experience shows that property owners who implement regular crack sealing programs spend significantly less on pavement maintenance over time compared to those who defer this critical maintenance.
What’s Included in Our Asphalt Crack Sealing Services?
Every NCGE project includes the assessment, prep, and protection work that makes the seal last:
- Crack Cleaning (debris, vegetation, and moisture cleared from each crack)
- Crack Routing (wide or worn cracks opened into a clean reservoir where the pavement calls for it)
- Hot-Pour Rubberized Sealing
- Cold-Pour Sealants
- Overbanding (a protective band over sealed cracks on high-traffic surfaces)
The Noble Cortes Crack Sealing Advantage

- Determination of optimal sealing materials and techniques
Material Quality
- Professional cleaning of cracks with compressed air and heat lancing
- Removal of vegetation and debris from crack channels
- Proper timing based on temperature and moisture conditions
Premium Application
- Hot-applied rubberized sealants for maximum adhesion and flexibility
- Calibrated equipment for precise application temperatures
- Proper overband techniques to maximize sealant effectiveness
Quality Assurance
- Inspection of completed work for proper adhesion
- Documentation of treated areas for maintenance records
- Recommendations for ongoing pavement preservation strategies
5 Common Types of Asphalt Cracks We Seal
Different crack patterns indicate specific pavement issues that require tailored approaches:
Transverse Cracks
These cracks run perpendicular to the pavement’s centerline and typically result from thermal contraction, hardening of the asphalt binder, or reflective cracking from underlying layers. They require thorough cleaning and proper sealant application to prevent water infiltration.
Longitudinal Cracks
Running parallel to the centerline, these cracks often result from improper joint construction, pavement fatigue, or subgrade settlement. Our approach includes evaluating the underlying cause while providing effective sealing to prevent further damage.
Block Cracks
These interconnected cracks form rectangular pieces and indicate asphalt hardening or seasonal temperature cycling. Our treatment includes proper routing and sealing with flexible materials designed to accommodate continued movement.
Edge Cracks
Occurring along the outside edge of pavements, these cracks indicate lack of lateral support or poor drainage. Our comprehensive approach addresses the sealing needs while providing recommendations for addressing the underlying causes.
Alligator Cracks
These interconnected cracks forming a pattern resembling alligator skin indicate more serious structural failure. While crack sealing alone isn’t sufficient for these areas, we identify these issues during our assessment and recommend appropriate rehabilitation strategies.

How Much Does Asphalt Crack Sealing Cost?
In Northern California, professional asphalt crack sealing typically costs $0.75 to $2.50 per linear foot.
Scope | Typical range |
Small residential (per linear foot) | $1.00 to $3.00 / linear ft |
Whole-driveway crack repair (total) | $200 to $600 |
Minimum service fee | $150 to $500 |
Commercial / municipal (per linear foot) | $0.50 to $1.50 / linear ft |
Rout-and-seal (mechanical routing) | $1.50 to $3.00 / linear ft |
What moves the number: crack width and depth, whether cracks need mechanical routing, hot-applied rubberized versus cold-pour material, and mobilization fees of $300 to $800 or more. Bundled into a sealcoating program, crack sealing runs about $0.60 to $0.80 per square foot combined. Bay Area and Sacramento AQMD rules require VOC-compliant rubberized emulsions, and mountain regions like Truckee, Redding, and the Sierra foothills use hot-applied rubberized tar that flexes through freeze-thaw. NCGE quotes are firm after a site visit.

Frequently Asked Questions
Crack sealing vs. sealcoating and slurry seal: what is the difference?
Crack sealing fills and seals individual cracks. Sealcoating or slurry seals are surface-wide treatments that protect the whole pavement. They solve different problems, so crack sealing comes first: we seal the cracks, then you protect the surface with our sealcoating or slurry seal.
Hot-pour or cold-pour: which method is right for a residential pavement?
Hot-pour rubberized sealant is for working cracks and long-term durability. Cold-pour suits smaller, stable cracks and lighter-use surfaces. We match the method to your pavement crack width, movement, and traffic.
How long will your crack sealing last before we need it again?
In Northern California, crack sealing usually lasts 3 to 5 years. The lifespan depends on local weather, traffic volume, and the quality of the sealant used on the asphalt. A low traffic area can last for up to 8 years.
Can we just use a store-bought crack filler instead of hiring you?
Sure. If you have a few thin hairline cracks, a store-bought filler is a reasonable stopgap, and we would not push you past that. However, if the cracks are wider than about an eighth of an inch or moving with the seasons, they pull away within a year and water gets back into the base. Such cases particularly require professional crack sealing because it holds for years and protects the further damage/repair cost.
Is crack sealing actually worth it, or should we just wait?
It is worth it. Sealing a crack early costs a fraction of the pothole or base repair it prevents, and properly sealed pavement lasts 25 to 30 percent longer. Waiting lets water into the base, which turns a cheap fix into a costly one.
