Asphalt Crack Sealing in New Jersey
Stop small cracks from becoming expensive problems. Professional crack sealing prevents water infiltration and extends pavement life by years.
Why Professional Crack Sealing?
Prevent costly repairs with proactive crack maintenance
Prevents Water Damage
Sealed cracks stop water from penetrating the asphalt base—the primary cause of potholes and pavement failure.
Freeze-Thaw Protection
Water in cracks expands when frozen, making cracks larger each winter. Sealing stops this destructive cycle.
Saves Money Long-Term
A $200 crack repair today prevents a $2,000 pothole repair or $20,000 section replacement later.
Extends Pavement Life
Regular crack sealing combined with sealcoating can double or triple your pavement lifespan.

Our 5-Step Process
From assessment to completion, we deliver lasting repairs
Crack Assessment
We inspect all cracks, measure widths and depths, identify underlying causes, and determine the appropriate repair method for each type.
Cleaning & Preparation
Using wire brushes, air blowers, and sometimes routing equipment, we remove debris, vegetation, and loose material from each crack.
Sealant Application
Hot-pour rubberized sealant is applied at the proper temperature, filling cracks completely and creating a watertight, flexible seal.
Finishing
Excess material is squeegeed smooth and flush with the surface. The sealant is allowed to cure before traffic resumes.
Documentation
We document all repairs and provide maintenance recommendations to help you budget for future preventive care.
Professional Equipment for Lasting Repairs
We use commercial-grade hot-pour sealant and professional equipment to ensure your crack repairs last for years. Our team carefully prepares each crack, removing debris and vegetation before applying the heated rubberized sealant.
This method creates a flexible, waterproof seal that expands and contracts with temperature changes, preventing water infiltration and further damage to your pavement.

Pothole Repair
When cracks go too long without repair, they become potholes. If your lot has both, we fix potholes and seal remaining cracks in one visit.

Frequently Asked Questions
Everything you need to know about crack sealing
We effectively seal cracks from hairline width up to about 1 inch. Cracks wider than 1 inch may require patching or more extensive repair. Very small hairline cracks are often addressed during sealcoating rather than individual sealing.
Quality hot-pour crack sealing typically lasts 3-5 years depending on traffic and weather exposure. The rubberized material remains flexible through temperature cycles, but should be inspected annually and resealed as needed.
We use commercial-grade hot-pour rubberized crack sealant that remains flexible in cold weather and stable in heat. This material bonds to both sides of the crack and moves with the pavement through seasonal temperature changes.
Yes! Crack sealing should always be done before sealcoating for best results. Sealcoating over open cracks provides only temporary cover—water will still penetrate. We recommend crack sealing, then sealcoating 2-4 weeks later.
Alligator cracking usually indicates base failure and requires more than surface sealing. Depending on severity, we may recommend infrared patching, full-depth patching, or section replacement. We provide honest assessments of what each area needs.
Hot-pour sealant typically cures enough for traffic in 15-30 minutes depending on temperature. We monitor curing and will let you know exactly when your surface is ready for vehicles.
Our primary focus is asphalt surfaces. Concrete crack repair uses different materials and techniques. We can provide recommendations for concrete specialists if needed.
We recommend inspecting your pavement annually, typically in spring, and sealing any new cracks before they grow. Proactive crack sealing as part of a maintenance program prevents small issues from becoming major repairs.
