I started asphalt sealing many many years ago in high school. My first truck was a three hundred dollar beater that I could put a couple of buckets and a squeegee and seal a few driveways in a day. With hard work I have built a sealing business that works from sun up to sun down seven days a week in the sealing season. Here are a few tips that have given me an edge over my competitors through the years. First of all, provide your customers with the best materials available on the market in your area. This includes Federal Specification concentrate,sand and additives. Add the proper formula, do not dilute your sealer by adding too much water. Secondly, be neat, weed wack, power blow and edge around retaining walls and close to the garage door. If a customer wanted sealer on his door or wall, he would not have called you, he could have done that himself. Leave the job site the looking professional. This means clean up any garbage that your workers have left around. Tie a strong caution tape barrier in front of the driveway and ask the homeowner if it would be ok to leave an advertisement sign next to the driveway. After the job, always thank the customer for choosing your service. Address any questions or concerns about the job when you are there. If the customer is happy, politely hint that a referral would greatly appreciated. I could go on and on but last of all, always project yourself as a professional. When you are providing an estimate you are providing the best sealing application on the market. There will always be guys who can undercut you with price but once you get a reputation for offering professional workmanship the phone will not stop ringing.
