Asphalt Sealcoating
Protect Your Asphalt and Add Years to Its Life
Sealcoating is the protective layer that keeps asphalt from drying out, cracking, and falling apart under sun, water, and traffic. Tri-State Paving and Construction applies commercial-grade sealer to driveways and lots, sealing the surface against the damage that ages pavement before its time.
Our owner-operated crews handle sealcoating in-house across Pennsylvania, Delaware, and Maryland, with no subcontractors on any job. Sealcoating works best as part of a maintenance routine: a fresh driveway or parking lot should be sealed once it cures, and pairing it with infrared repairs fixes cracks and potholes before the sealer goes down. We clean the surface, fill the cracks, and apply an even coat that restores the deep black finish and shields the asphalt underneath.
Signs Your Asphalt Needs Sealing:
The surface has faded from black to a dry, weathered gray
It’s been more than two or three years since the last seal
The asphalt feels rough, brittle, or has begun to ravel
Your new pavement has cured and is ready for its first coat
What Sealcoating Does for Your Pavement
Sealing asphalt every few years costs a fraction of repaving and dramatically extends how long a surface lasts, protecting the investment you already made in the pavement:
Blocks water, UV, and oxidation, the main causes of asphalt breakdown
Extends pavement life and delays the cost of a full replacement
Restores the deep black finish that makes a surface look new
Resists oil, gas, and chemical stains that eat into bare asphalt
