Seal an Asphalt Driveway Cost

How much does it cost to seal an asphalt driveway?

Anyone who owns a home already knows the importance of maintaining "curb appeal". This might mean keeping the grass mowed, gardens weeded, and the exterior of the house in tip top condition. One of the biggest impediments to curb appeal, however, is a driveway in somewhat shabby condition. When it is an asphalt driveway this sort of problem is quickly and inexpensively addressed.

For the purpose of this discussion we will take a look at the costs and requirements for sealing an asphalt driveway on a DIY basis. The measurements of the drive will be 15'x50' (or 750 square feet) which is considered a fairly common sizing. This is an extremely simple project, and it would be entirely inefficient for even the most unskilled homeowner to subcontract the work.

Cost breakout

According to DIYOrNot.com the costs associated with the sealing of an asphalt driveway project include:

  • Asphalt sealer - it is important to remember that the job will demand patching of holes and cracks and a comprehensive sealing. For a project in the size described it is going to demand several gallons of sealant at the very least. These average around $30 each, and tubes of sealant are priced around $6 each. When a sealant is mixed with a 1:1 ratio of sand it often improves the results, but this usually cuts the coverage of a single gallon down to between 15 and 55 square feet per gallon;
  • Tools - a wide squeegee, paint sticks, empty buckets, and a spare 2x4 board are usually essentials in any asphalt sealing project. Additionally, it is usually necessary to have gloves, a shop broom (with which to sweep the entire drive before applying any sealants), and even a trowel to make effective repairs; and
  • Weed removal - most people understand the hazards of herbicides and pesticides, and though it is crucial to eliminate all growth abutting the edge of the drive, it is best to use weed removal and gardening tools to tackle the work.

Enhancement and improvement costs

  • Macadam - in addition to sealing an asphalt driveway every two to six years, it might be a good plan to consider a macadam installation if the drive has seriously deteriorated. This is the use of gravel and liquid asphalt applied to a pre-existing driveway. This is something that will last for around six years at a time and comes in at a cost of $2 per square foot. For the project described here it would cost around $1500 to complete but this is far less expensive than paying a contractor to tear up an existing pavement and reinstall the asphalt; and
  • Curbing - while working on the drive in this way it will be necessary to remove weeds and growth that is creeping into the pavement. This might be the ideal opportunity to install granite or cast concrete curbing of some kind. This will support the drive, boost curb appeal, and deliver a cost effective way to help with drainage.
