Why is sealcoating important?
Sealcoating is the most cost-effective solution that prevents further deterioration and enhances the beauty of your asphalt. Sealing will allow the pavement to have a much longer life than that of an unsealed pavement.
Deterioration begins as soon as the asphalt is put down — under normal conditions, significant problems typically appear within three to five years. Sealing early, and on a regular schedule, is how you stay ahead of it and protect what you’ve already paid for.
