Asphalt crack sealing routes and fills active cracks with hot-pour rubberized sealant before water can reach the base. Sealed annually as part of a maintenance program, it can add 5 to 7 years of useful life to an existing parking lot or driveway at a fraction of the cost of repair or replacement.

What this service includes
Every crack sealing project from Maisano Brothers Inc. covers the work that makes the result last.
Crack inspection and routing
We walk the surface, mark active cracks, and route the larger ones to create a clean reservoir for the sealant to bond.
Surface preparation
Cracks are blown clean of dust, debris, and vegetation so the sealant bonds to clean pavement walls.
Hot-pour rubberized sealant
We apply ASTM-grade hot-pour sealant heated to spec for proper flow and bond, formulated for New England temperature swings.
Squeegee or band finish
Depending on crack size and your preference, we leave a flush seal or a banded overband that adds wear protection across the joint.
Cure and reopen
Most sections of the lot are ready for traffic within an hour. We coordinate cure time around your operating hours so business does not stop.
When this service makes sense
- Visible cracks have appeared but the pavement is otherwise sound.
- You want to extend the life of an existing driveway or lot before the next sealcoat cycle.
- You manage a property and need a recurring annual maintenance plan to protect the asset.
- A lot is approaching the age where small cracks become potholes if ignored.
- You are budgeting maintenance and want the highest dollar-for-dollar life extension.

Sealant is heated to specification and applied with a controlled wand for consistent fill and bond.
- 5
Walkthrough and reopen
We walk the work with you, confirm cure times for each section, and reopen the lot to traffic.
Materials, equipment, and quality
The standards and details that separate work built to last from work built to look finished.
ASTM D6690 hot-pour sealant
We use grade-appropriate sealant formulated for the climate, not cold-pour caulks that fail in the first winter.
Proper application temperature
Sealant viscosity, pavement temperature, and ambient conditions all affect bond. We work to spec, not to the clock.
Honest scope
We tell you when a crack is past sealing and needs patch repair or partial replacement instead — sealing failed pavement is a waste of money.
Coordinated with sealcoating
Crack sealing is the preferred prep for a sealcoat cycle. Done together, the surface lasts noticeably longer.

What is the difference between crack sealing and crack filling?
Crack sealing uses hot-pour rubberized sealant designed to flex with the pavement through freeze-thaw cycles. Crack filling typically uses lower-grade cold-pour material and is shorter-lived. For Connecticut climate we use hot-pour sealing.
How often should we crack-seal a commercial parking lot?
Most properties benefit from annual or two-year crack-sealing cycles, scheduled in spring or fall when temperatures are moderate. The right interval depends on age, condition, and traffic — we recommend a frequency during the assessment.
Can a crack-sealed lot still be sealcoated?
Yes — crack sealing is the recommended preparation before sealcoating. The sealant fills the structural opening and the sealcoat protects the surface, and together they give the longest extension on the existing pavement.
How long does crack sealant last?
Properly applied hot-pour sealant typically lasts 3 to 7 years before the original crack reopens enough to need re-sealing. Newer cracks elsewhere on the surface are sealed as part of the regular maintenance cycle.
When is crack sealing not the right answer?
When the base under the crack has failed, when alligator cracking covers wide areas, or when cracks are wider than about 1.5 inches, we recommend patch repair or replacement instead. We tell you honestly when sealing would be a waste.
