Do It Yourself
If you decide to seal your own driveway you need to purchase a few items to ensure you complete the sealing properly. First, you need to clean the driveway of oil stains and other blemishes. Then you need to fill in any cracks in the driveway to allow the seal coat to adhere to a relatively flat surface. When that is complete, you need the following:
- Driveway Prep Solution (for oil spots): $8 to $15 per gallon, average of $12.
- Driveway Crack Filler: $7 to $25 a gallon, with an average of $12.
- Driveway Seal Coat: $8 to $40 per 5 gallon pail, with an average of $15.
- Seal Coat Squeegee or Brush: $30 to $100 depending on size and materials with an average of $50.
One gallon of driveway crack filler will fill 70-150 feet of cracks. Each 5-gallon bucket of quality sealant will usually cover between 250-350 sq. ft of driveway.
The Bottom Line
For a 1,000 square foot driveway, the costs per option would be:
- Professional Seal Coating: $170 on average.
- Do It Yourself: $140 on average.
- DIY includes hardware that can be reused in the future, reducing your costs on subsequent coats.
