General contractor in Portsmouth
Portsmouth's older housing stock means many driveways sit on aging asphalt and hand-laid edges that crack and shed fines over time. Cold, snowy winters and freeze-thaw cycles widen those cracks, so sealing and crack work matter here more than in milder towns.

CJT Driveway Sealcoating in Portsmouth
Driveway Care Built for Portsmouth's Older Properties
Many Portsmouth properties date to the 1700s and 1800s, and their driveways often reflect decades of patching. Before sealing, we clean and prep the surface so the new coat bonds to the existing asphalt or concrete. Crack filling and crack sealing come first on any driveway with open joints.
Winters here bring freezing nights on roughly 150 days a year and repeated snowmelt. Water that seeps into hairline cracks freezes and expands, so we address those openings before the first hard frost. Parking lot sealcoating handles larger commercial and multi-unit lots downtown and along the corridors.
Portsmouth's downtown historic district places limits on exterior changes, but driveways and surfaces are typically outside the building itself. Our work focuses on the pavement, with clear notes on what each surface needs before we begin.
