It’s especially important in areas like Rochester, NY, where weather conditions fluctuate dramatically.

🧰 DIY: How to Seal Your Asphalt Driveway in 6 Steps

If you’re a homeowner looking to tackle sealing on your own, follow these steps carefully:

Step 1: Clean the Driveway

Remove all debris, dirt, and loose gravel using a broom or pressure washer. For heavy oil stains, use a degreaser or driveway cleaner.

Step 2: Edge Trimming

Trim back grass and weeds from the edges to ensure the sealant fully adheres along borders.

Step 3: Crack Repair

Use crack filler to seal any gaps or fractures. For larger cracks (over ½”), consider using a trowel-grade crack sealer.
