Asphalt driveways should get resealed after three to five years of use. This will help minimize cracking and staining, protect your driveway from the elements, prolong its life, and add to your home’s curb appeal.

The national average to seal an asphalt driveway is $450. However, it could cost you as little as $100 or as much as $1,350. The typical range for a professionally sealed driveway is $250 to $600. Adding sealant for walkways, patios, and basketball courts will increase the price.

Given that a new asphalt driveway costs $4,500 on average, sealing it to keep it in good condition is a worthwhile investment.

A new winding asphalt driveway

The most significant effect on the price to seal your asphalt driveway is the size. Most sealing professionals price their services by the square foot. You can find the size of your driveway in square feet using our square footage calculator or asphalt driveway calculator.

From there, you will be able to determine how much sealant and other materials you will need to complete the project, if you are planning a DIY, or how much you should pay a professional based on the price per square foot.

Asphalt sealant is usually available in five-gallon buckets and costs between $.06 and $.38 per square foot of coverage. The typical two-car driveway is 24’ x 20’ and the price to seal it depends on how much preparation is required, how many coats, the type of sealer used, and whether you DIY or hire a professional.

Types of Sealant to Use

There are basically five types of asphalt driveway sealants: fast-drying, polymer emulsion, coal tar, latex acrylic, and eco-friendly. Each has advantages and disadvantages that you should consider, and the price is one of the main factors.

Although these sealants come in five-gallon buckets, there is typically 4.75 gallons of sealant.

Fast-Drying

One of the apparent advantages of a fast-drying sealant is how quickly you can use your driveway, patio, or walkway after application. A walkway or patio can normally get used after an hour or two, depending on the weather, and it can get driven on after one day.

This sealant usually needs to get resealed after only two to three years but costs about $30 – $85 per five-gallon bucket; which covers 450-475 square feet.

Asphalt Emulsion

This sealant is more durable and eco-friendly than the fast-drying sealant. It must be applied in warm to hot weather, is subject to oil and gasoline stains, and costs $.08 – $.10 per square foot of coverage.

One five-gallon bucket is $85 to $100. Professionals typically buy the 55-gallon container for $550.

Coal Tar

This sealant is one of the most popular choices for homeowners. It doesn’t stain as easily as the polymer emulsion, but it is one of the worst for the environment, as it emits pollutants and carcinogens. It costs about $.06 – $.08 per square foot, or $37 – $45 for a five-gallon bucket that covers 500 – 600 square feet.

Latex Acrylic

Latex acrylic is a synthetic mix of polymers and acrylics, most often used by professionals. It is supposedly not harmful to the environment and does not stain easily. It costs $.20 – $25 per square foot or about $100 – $110 for a five-gallon bucket.

Eco-Friendly

This sealant is the best for the environment but the most expensive at $165 for a five-gallon bucket that covers 400 – 500 square feet, or about $.38 per square foot.

Tools Needed for a DIY Sealant Application

Although you might have some of these tools on-hand or improvise with tools you do have, this is what you will need:

  • A high-pressure washer and soap
  • One quart of spot primer
  • A seal coating broom or applicator
  • A mixing stir stick or paddle
  • Sealant, depending on the square footage, to cover a number of coats

Renting a power wash machine is one option that will cost $50 – $120 per day. However, another choice is to buy a pivot jet extension for your water hose, which costs $30 – $60. This extension cleans out the cracks in your driveway before filling those with asphalt crack filler.

Crack filler ranges from $5.00 for a tube that fits a caulking gun to $25 for a gallon at most hardware supply stores. The total for all this should be around $150 to $200, without the sealant.

Professional Application Costs

Asphalt sealing professionals typically charge $35 – $50 per hour for the preparation and application of driveway sealer. Since prepping and sealing a 480 – 500 square foot driveway takes two people eight to twelve hours, labor will cost about $280 to $600.

The following are three factors that could affect how much you pay:

Accessibility

Patios and walkways included in your sealant project that are not accessible to the contractor will cost more to seal.

Cost Per Coat

When you request two coats, the second coat will not cost as much per square foot as the first. However, it will require the landscaper or contractor to wait 24 hours to come back and add a second coat, which will add to your overall price per square foot.

Residential driveways, patios, and walkways should not require two coats, but that is a personal choice.

Enhancements

Professionals can make your sealer different colors and add sand to make your driveway less slippery in cold weather.

Hiring a Professional

When you decide to hire a professional to seal your asphalt driveway, we suggest getting several estimates for the work, compare their prices against their statements of work, and choose a licensed professional who offers a warranty.
