Residential Sealcoating
We sealcoat driveways across southern New Hampshire with commercial-grade sealer applied for full, even coverage. A proper sealcoat restores the deep black finish, seals hairline cracks before they become real cracks, and shields the surface from oil, gas, and UV damage. Most NH driveways should be sealcoated every 2 to 3 years. If yours is gray, faded, or showing spiderweb cracking, it is past due.
Commercial Sealcoating and Line Striping
For parking lots, sealcoating is asset protection. A sealed lot resists plow damage and salt, and fresh line striping keeps the lot safe and professional-looking. We schedule commercial work in phases around your business hours so you never lose your whole lot at once. Sealcoating on a regular schedule is how a parking lot stays out of the expensive-repair stage, and it is the smartest money a property manager spends on asphalt.
Crack Filling First
Sealer over open cracks is wasted money, which is why crack filling comes before sealcoating on any surface that needs it. Water gets locked out before the sealcoat goes down.That is the step that separates a real sealcoating job from a driveway that looks good for one season. See finished work on our sealcoating projects page.
We provide paving and sealcoating together for customers who need repair plus protection, and we serve Londonderry, Concord, and towns throughout the region.
