Sealcoating is a preventive measure to protect streets from deterioration. A layer of liquid asphalt is applied, followed by a layer of small stones to seal the road to prevent water from entering cracks and causing further deterioration. This work is performed as preventive maintenance, and the cost is not assessed to property owners.

What to Expect

Temporary “No Parking” signs will be placed on streets one to two days prior to the work, weather permitting. There may be a 15-minute window when the street or your driveway is not accessible while work is being completed. 

Once the stone is placed, you can drive on the street immediately. Vehicle traffic helps work the remaining stone into the oil, creating a smooth surface over time. 

A few weeks later, the contractor will sweep and remove loose stones. A second sweep will be completed at a later time. Temporary “No Parking” signs may be placed prior to sweeping and will be removed after sweeping has been completed.  

When Action is Required

If you have any private contractor coming to do work at your property after the sealcoating is done, please contact the Engineering Division. Construction equipment used by private contractors damages the sealcoated surface. We will work with them to minimize turning movements and damage on freshly coated streets. Damages to the street’s surface may be charged to the private contractor.

If any loose aggregate ends up in your driveway or grassed terrace area after the sealcoat operation is complete, please push it into the curb and gutter areas to be swept by our regular street sweeping operations.
