"We had Ocean Seven Builders redo our roof after a small leak turned into a bigger problem. Ron was the one we dealt with, and he just felt easy to talk to from the start. No pressure, no upselling, just explained what made sense. The crew showed up when they said they would and worked pretty steadily through the job. What I noticed most was how clean they kept things?no nails or trash left around. The roof looks great and we?ve had zero issues since."

"Mega Power was great! I hired them to go solar on my house and the solar analyst that came out was very helpful from day one. He was not just simply a sales guy he gave me his personal cell phone that I was able to call anytime if I had questions or wanted updates about my project.
My project was about 6 kW and consisted of 22 panels, each panel was 275 Watts. What I loved about these guys is that all the products they installed were American made products, warrantied for 25 years! Working with Jonathan (our sales guy) was another reason I chose to go with Mega Power. Every step of the way Jonathan was informative, and just professional from day 1. Price quotes with other companies were similar, so I simply chose the company that provided me the best service before signing anything."

Driveway Sealcoating FAQs, answered by experts

Sealing your driveway gives it the longest possible lifespan. You’ll reduce your driveway’s risk of cracking, breaking down from exposure to UV light, discoloring, and staining from road chemicals.

Asphalt is made of aggregate materials (sand, rocks, and gravel) and bitumen, a viscous, petroleum-based, waterproof substance. These materials are mixed together at extremely high temperatures to form asphalt.

When asphalt cures, it typically changes from a very dark black hue to a lighter, more matte gray color. Cured asphalt also won’t be tacky or sticky to the touch or emit any odors from the asphalt mix. Additionally, the surface of fully cured asphalt won’t deform under any pressure.

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.

Chip seal roads and driveways are slightly more expensive than gravel, but significantly more affordable than traditional asphalt. Chip seal works wonders when used as a top coat. Its lighter color is less heat-absorbant than black asphalt. It also renews your aging, deteriorating asphalt without having to spend on major repairs or redoing the entire driveway.
