Welcome to Affordable Asphalt.

We are one of the leading Seal Coating companies in the Portland metro area.

What is Seal Coating?

Seal Coating is an asphalt-based emulsion that is applied directly to aged asphalt as a protective coating to extend the life of your parking lot or driveway. Other terms commonly used are: driveway sealing, asphalt sealing, asphalt repair, black top sealing, or black top repair.

Why is Seal Coating Important?

An continuous asphalt maintenance program should include seal coating your driveway every 3 years as it not only saves you money in costly asphalt repairs but also can greatly extend the lifespan of your asphalt surface. In addition, seal coating provides a barrier to salts, chemicals, and petroleum products which break down asphalt. Seal coating also makes your surface waterproof, which is especially important here in the Northwest where heavy rain can work its way to the base of the asphalt leading to cracks and much larger repairs. And let's not forget how great a newly sealed driveway looks! You'll be instantly adding value to your home or business, which is especially nice if you're thinking of selling soon.
