Frequently Asked Questions

Asphalt paving involves installing or resurfacing a complete pavement layer with new asphalt, while seal coating applies a protective topcoat to extend the life of existing asphalt. Seal coating prevents cracking and surface deterioration, making it a cost-effective maintenance solution. At GM Grading and Paving, we recommend seal coating every few years to protect your investment.

Proper grading ensures correct slope and leveling, which creates a stable base for paving and concrete while supporting natural drainage flow. Without precise grading, surfaces can settle unevenly or develop premature cracking. GM Grading and Paving uses accurate measurements and equipment to prepare every site for long-term stability.

Seal coating should typically be applied every two to three years or when you notice surface wear, fading, or minor cracks beginning to form. It's best scheduled during dry, warm weather for optimal curing. In Wilton, CA, late spring through early fall provides ideal conditions for seal coating applications.
