When considering the cost of sealcoating asphalt pavement, it’s just as important to consider the cost of not sealcoating asphalt pavement.
Not sealcoating asphalt will lead to premature failure of the pavement due to oxidation, UV degradation, weathering, oil spills and other environmental distress. Just as one protects exterior wood and metal from the effects of weathering, one should also protect asphalt pavement in the same way. Sealcoating provides a protective coating over the asphalt surface. A scheduled program of crack filling and sealcoating will more than double the life of the asphalt pavement at a fraction of the cost of having to repave with hot mix asphalt (blacktop).
In addition to the protection that sealcoating provides, almost as important is the aesthetics and beautification that sealcoating provides. Your parking lot or driveway is the welcome mat to your property. Do you want it to portray a drab gray weathered and oxidized appearance or fresh, black “like new” appearance that portrays a professionally maintained pavement surface?
There are several factors that affect the cost of sealcoating pavement including:
• Geographical location
• Type of sealer being applied (asphalt based, coal tar based, acrylic based, etc.)
• Amount of asphalt repairs needed (crack filling, pothole repair, etc.)
• Number of coats of sealer that is applied
• Size of the area to be sealcoated (parking lot or driveway)
• Mobilization costs (large areas to be sealed in “sections”)
The typical cost of sealcoating ranges anywhere from 10 cents to 30 cents a square foot depending on the factors listed above. Overall, sealcoating is typically less than one-tenth the cost of paving with an asphalt overlay.
