Crack Cleaning
Debris, sand, and vegetation removed so the material bonds to clean crack walls.
Crack Filling & Sealing
Crack Filling and Crack Sealing for Asphalt Surfaces
Water entering a crack is how most Cape Cod pavement fails. Treating cracks early is the cheapest work you will ever do on a driveway.
Cracks Are a Water Problem
A crack is not a cosmetic issue. It is an opening that lets water reach the base, where freeze-thaw cycles do the real damage.

Once water gets past the surface it saturates the base material. In winter it freezes, expands, and lifts the pavement; in spring it thaws and leaves voids. The crack widens, the edges break down, and what began as a hairline separation becomes a structural failure that requires repair or replacement.
Treating cracks while they are still narrow is the highest-return maintenance available for asphalt. It costs a fraction of repair and delays replacement by years.
Crack Filling vs. Crack Sealing
Crack filling places material into the crack to block water. It suits narrow, non-working cracks that are not moving much with temperature. Hot-pour crack sealing uses a flexible material applied hot that bonds to the crack walls and can move with the pavement through the seasons. It is the better treatment for working cracks that expand and contract.
We choose the method based on crack width, movement, and the overall condition of the surface, and we tell you which one we are recommending and why.
Preparation Matters
Material placed into a dirty or wet crack does not bond. Cracks are cleaned of debris, sand, and vegetation before any material goes in. Skipping that step is why so much crack work fails within a single season.
What Cracks Cannot Fix
Interconnected alligator cracking indicates base failure rather than a surface separation. Filling it does not restore structure. In those areas we recommend repair or replacement instead of a treatment that will not hold.
Scope
What Crack Work Covers
Crack Filling
Material placed into narrow, non-working cracks to block water intrusion.
Hot-Pour Crack Sealing
Flexible hot-applied sealant for working cracks that move with temperature changes.
Joint Treatment
Attention to joints and transitions where pavement meets other surfaces.
Condition Assessment
Identification of areas where cracking signals base failure rather than a surface issue.
Pre-Sealcoat Prep
Crack treatment completed before sealcoating so the finished surface performs correctly.
Questions
Frequently Asked Questions
What is the difference between crack filling and crack sealing?
Crack filling blocks water in narrow, stable cracks. Hot-pour crack sealing uses a flexible material that bonds to the crack walls and moves with the pavement, which suits wider working cracks.
When should cracks be treated?
As early as they appear. A narrow crack is inexpensive to treat; the same crack after two winters of water intrusion often requires repair instead.
Should cracks be sealed before sealcoating?
Yes. Sealcoat is a thin surface layer and will not bridge a crack. Crack treatment comes first so the sealed surface performs as intended.
Can every crack be sealed?
No. Interconnected alligator cracking means the base has failed. Those areas need repair or replacement rather than crack treatment.
How long does crack sealing last?
It depends on movement, traffic, and preparation. Properly cleaned and correctly treated cracks generally hold for several seasons before needing review.
How much does crack filling & sealing cost?
Pricing depends on measured area, pavement condition, preparation, access, drainage, and required materials. RS Superior inspects the property and provides a written scope rather than quoting an unreliable universal per-square-foot price.
How do I know whether crack filling & sealing is the right service?
The deciding factors are surface condition, base stability, drainage, and the extent of cracking or settlement. We assess those conditions first and explain whether maintenance, localized repair, resurfacing, or replacement is appropriate.
