sealcoating and crack repair in New Hampshire

Benefits of sealcoating

  • Resists gas and oil spills that can soften asphalt
  • Restores a deep black color back to the pavement, improving its appearance


When should you apply sealcoat? Wait at least one to two years before you sealcoat a newly paved driveway or parking area, then seal every two to three years or as needed.


Don't let cracks ruin your driveway or parking area!


Cracks in asphalt pavement can threaten the overall strength of the pavement. Cracks can also allow water to penetrate into the pavement, seeping into the underlying base layers. The result is voids or potholes that will eventually destroy your asphalt’s foundation.


We take great pride in the quality of our workmanship and the professionalism and courtesy of our crew members. Much of our business is the result of personal referrals from satisfied customers. Our sealcoating/crackfilling division is happy to answer any questions concerning your parking lot or driveway restoration needs. Please call us today at (603) 883-5250 for a free estimate!
