Best driveway sealcoating pros near Pierre, SD

You should always power wash your driveway before applying a sealant. At any given time, your driveway could be covered with algae and moss, tire residue, oil and rust stains, and any combination of leaves, twigs, and dirt. If you skip power washing, you’ll be trapping the dirt and grime beneath the sealant and lowering its chance of cementing itself to your driveway. While you can expect the cost to pressure wash your driveway to average between $100 and $350, the few hundred dollars beats an unattractive driveway or paying extra to reapply your driveway sealer.

New asphalt typically needs 24 to 72 hours to dry before it can handle light foot traffic and careful driving. Although it may appear solid after a few days, the full curing process, where the asphalt reaches its peak strength, takes much longer—generally from 30 days to a year.

During this extended curing time, the surface remains relatively soft and can be damaged by heavy vehicles, sharp objects, or high temperatures. To protect your investment, it's best to avoid parking heavy machinery on the asphalt until it has fully cured.

The exact time required for drying and curing depends on several factors, including the weather, the specific asphalt mix, and its thickness. For the most accurate advice tailored to your situation, consult with your asphalt contractor.

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.

To maintain your asphalt driveway, add a new coat of sealant every three to five years. Pricing varies, but you will pay about $0.08 to $0.50 per square foot from start to finish. You can also choose to add a fill-and-seal layer that includes a layer of aggregate to fortify a damaged top layer of asphalt.
