Best driveway sealcoating pros near Ferguson, MO

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.

Maintaining a driveway depends on its material. For concrete and asphalt, it's best to clean the surface thoroughly twice a year with a stiff broom and a pressure washer to remove accumulated dirt and debris. Sealing the driveway is crucial to protect it from water damage and freeze-thaw cycles. Before applying a sealant, pressure wash the surface to remove any loose sealant, dirt, or stains, as sealing over them will trap them. Any cracks or expansion joints should be filled with a flexible polyurethane caulk or asphalt sealer. In colder climates, use sand instead of salt for de-icing. Sand helps melt snow and ice without accelerating the freeze-thaw process, which can cause cracks.

One of the easiest ways to avoid poor customer service and poor sealant application is to hire a reputable, licensed company. Contact companies with positive customer reviews and Better Business Bureau (BBB) ratings, and ask for customer references from any company you’re considering hiring to seal your driveway. Get price quotes from three local driveway sealcoating companies to compare pricing and services to find the best fit for your home.

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.
