Expert Driveway sealcoating in Rochester, NH
Driveway sealcoating is one of the most practical ways Rochester homeowners can protect an asphalt surface from the freeze-thaw cycles that define New Hampshire winters. Water works into small surface voids, freezes, expands, and widens cracks from the inside out. Left untreated, that cycle turns a sound driveway into a crumbling one. At CJT Driveway Sealcoating, the owner handles every job personally. That means he fills every crack himself before a drop of sealer goes down, because sealer alone will not bridge open gaps. The surface is cleaned, cracks are filled, and the sealer is applied in a controlled, even coat. No shortcuts, no crew handoffs. That hands-on approach matters whether the driveway is in Rochester, Dover, Stratham, or any of the other communities we serve across Strafford and Rockingham counties. If your asphalt is fading, showing surface cracks, or has gone a few seasons without attention, sealcoating is the right next step before minor damage becomes a major repair bill.

FAQ
Driveway sealcoating FAQ
Common questions about driveway sealcoating in Rochester, NH.
Yes, cracks must be filled before sealer goes down. Sealer is too thin to bridge open gaps, so skipping this step lets water keep working into the base.
Most asphalt driveways in the Rochester area benefit from sealcoating every two to three years. Traffic, sun exposure, and surface condition all affect how quickly the previous coat wears.
New asphalt needs to cure for at least one full year before its first sealcoat. Sealing too early traps surface oils and prevents the coating from bonding correctly.
Sealcoating requires warm, dry conditions with pavement temperatures above 50 degrees Fahrenheit. In New Hampshire that practical window generally falls between late spring and early fall.
The owner shows up and does the work himself at every job, including all crack filling and sealcoating. There is no crew handoff at any point in the process.
Sealcoating works best on asphalt that is structurally sound. A driveway with severe cracking or base failure needs repair or replacement before sealcoating can protect it.
