"We knew our roof needed to be replaced for a while, but kept putting it off because it felt like such a big project. After meeting with Ocean Seven Builders, we felt comfortable moving forward. Ron was straightforward from day one and didn?t overcomplicate anything. He broke everything down in simple terms and gave us a realistic timeline. The crew worked fast, showed up when they said they would, and cleaned up every day. It?s been a few weeks now and everything looks great. Happy we finally got it done!"

Driveway Sealcoating FAQs, answered by experts

Like all driveway materials, asphalt can crack in the wrong conditions and with age. Many things can cause asphalt to crack, including shifting soil or settling under the foundation. Other common causes are driving oversized vehicles on the asphalt, tree roots, and using rock salt during the snowy season. Proper installation and sealing the driveway every 10 years can help prevent cracks.

The costs range from $0.15 to $0.50 per square foot, depending on the asphalt condition, sealant type, and labor.

To maintain their strength, asphalt driveways and parking lots need to be sealcoated once every two to five years. You may also need to reapply paint striping every few years as it fades to ensure drivers can safely navigate the parking lot.

Hot-pour sealants have an asphalt cement base that might also include rubber and other materials to allow the seal to flex in hot or cold temperatures. Asphalt emulsion sealants are not heated but are liquid applications that use water and an emulsifying agent to allow the asphalt and water to mix.

While blacktop is a type of asphalt, the terms should not be used interchangeably, as not all asphalt qualifies as blacktop. The primary differences are in their composition, production process, and ideal applications. Blacktop contains more stone than other types of asphalt and is heated to a higher temperature during production—300°F or more—while hot-mix asphalt is heated to between 275°F and 300°F. The ratio of bitumen (a tar-like crude oil) is a key differentiator, though sources vary: some state blacktop has less bitumen, making it less durable, while others claim it has a higher ratio. Due to these differences, asphalt is generally more durable and better for high-traffic areas like highways and streets, while blacktop is more suitable for playgrounds and residential driveways. For a driveway project, it is best to consult a professional to determine the most appropriate material.
