Parking Lot Sealcoating in Morris County, NJ
Protecting commercial asphalt from freeze-thaw damage, road salt, and UV oxidation. For office parks, retail centers, HOAs, and industrial properties.
Stock cabinetry is built in three-inch increments on the assumption that the room is square, the floor is level, and the walls are plumb. In a 1935 colonial in Bernardsville or a 1950s farmhouse conversion in Bedminster, none of those three things is true.
The result is familiar to anyone who has lived through a budget kitchen install: filler strips at every corner, a run that dies two inches short of the wall, scribe molding doing work it was never meant to do, and a countertop with a visible gap at the back. The cabinets weren’t wrong. The room was never going to accept them.
Custom cabinetry solves a fitting problem, not a taste problem.
What sealcoating does
Sealcoat is a protective layer applied over asphalt. It does not add structural strength — it protects the binder that holds the asphalt together from the three things that destroy it.
Water. Asphalt is porous. Water gets in, freezes, expands, and widens every crack it finds. In Morris County that cycle runs dozens of times a winter.
Road salt and chemicals. Deicers, motor oil, and hydraulic fluid break down the asphalt binder directly. Sealer takes that contact instead of the pavement.
UV. Sunlight oxidizes the binder, which is why old asphalt turns grey and loose aggregate starts coming up underfoot.
A commercial lot on a regular sealcoating cycle can substantially outlive one that is not. Replacement runs many times the cost of maintenance, which is the entire argument for doing it.
When your lot needs it
- The surface has faded from black to grey
- Loose aggregate comes up when you brush it with a shoe
- Hairline cracks are appearing across the surface
- Water sits on the lot instead of running off
- Oil stains have soaked in rather than sitting on top
- It has been more than three years since the last application
On cycle length. Most commercial lots are on a two to three year interval. Heavy truck traffic, poor drainage, and full sun exposure all shorten it. A lot that gets almost no traffic can stretch longer.
On season. Sealer needs surface temperatures above roughly 50 degrees and a dry forecast for the cure. In Morris County that is spring through early fall. Applying it cold or onto damp pavement causes adhesion failure that shows up the following season as peeling and bare patches.
What the work involves
Cleaning. The lot is blown and swept. Sealer will not bond to dirt, and anything left on the surface stays under the new coat.
Oil spot treatment. Petroleum contamination is primed separately. Sealer will not adhere over untreated oil, and those spots fail first.
Crack filling and repair. Cracks are filled and failed areas patched. Sealcoat is a coating, not a repair — putting it over open cracks hides a problem that returns within a season.
Application. Applied and left to cure. Cure time depends on temperature and humidity.
Restriping. Sealer covers every existing line. Restriping is part of the job, not an add-on.
Sealcoating always means restriping
There is no exception to this. Sealer goes over the whole surface, including stall lines, arrows, fire lanes, and every accessible marking.
Budget both together, schedule both together, and get one mobilization and one lot closure instead of two.
What sealcoating costs
Priced by square footage, adjusted for surface condition. A lot needing extensive crack filling and oil treatment costs more than one in good shape. Small lots carry a higher rate per square foot because mobilization is fixed.

Frequently Asked Questions
How long does the lot need to stay closed?
How long does the lot need to stay closed?
Will sealcoating fix cracks?
No. Cracks are filled first as a separate step. Sealer applied over open cracks conceals them briefly and they reopen.
How often should we do this?
Generally every two to three years for a commercial lot.
Can it be done in fall?
Only while surface temperatures stay high enough and the forecast is dry. Late-season applications are a real risk in this climate — the failure does not appear until spring.
Does it make the lot slippery?
Properly applied sealer with the correct aggregate additive is not slippery. Over-application or the wrong mix can be.
