Asphalt is a durable and cost-effective material; however, it is susceptible to the elements. As water, salt, and other materials seep into the asphalt, it loses some of its protective qualities. In order to prevent this, you can count on the fully licensed, bonded, and insured experts at ConTech Pro LLC. Our sealcoating services will save you money on repairs, and extend the life of your asphalt.
