Asphalt sealing: a guide for pros
What customers ask, how to win the job, and what to put on your profile.
Offering asphalt sealing
Sealcoating is a repeat-business service, and customers trust the crews who clean, repair and mask before they spray. Win the job by showing the cleaning and the crack work, and by setting a clear reseal schedule the customer can follow.
What customers ask
- Will sealcoat make my drive look new again?
- How long will the seal last before I need to do it again?
- Can you seal around my curbs and landscaping without a mess?
- How long before my car can drive on it?
- Will it make the surface slippery?
- Do you fix the cracks before you seal?
How to win the job
- On the first call, ask how old the surface is, when it was last sealed and where the cracks and oil spots are.
- On site, walk the surface, mark the cracks and oil spots, and check whether the base is sound, then tell the customer what must be repaired first.
- In the quote, separate the cleaning, the crack sealing, the sealcoat and the masking, so the customer sees the full scope.
- Show samples of the sealcoat finish on a board, and explain the difference between a standard and a polymer-modified product.
- Set a weather window and a cure plan in writing, since sealcoat must not be applied to wet or cold surfaces.
- Give the customer a reseal schedule and a note on keeping oil and fuel off the surface between seals.
What to put on your profile
- Before and after photos of sealed surfaces, shot wet and dry from the same angle
- Sealcoat products you use, including standard and polymer-modified types
- Surfaces you seal, such as residential drives, parking lots and commercial pads
- Your service area and whether you also do crack sealing, patching and striping
Follow-up that helps the customer
- Offer a reseal reminder on the schedule that suits the product and the traffic
- Suggest crack sealing before each reseal, explained as the step that keeps the seal working
- Mention striping or a parking layout as information when the customer is refreshing the lot
Licenses and permits
Whether sealcoating needs a contractor license varies by place and job size, and larger commercial work and any repairs that change grade or drainage are commonly done under a contractor license. Confirm what applies where you work with your state or local licensing agency and local building department, and keep your insurance current.
Questions
What do I do when the customer wants a seal over a failing surface?
Tell the customer that sealcoat will not hold on a surface that is breaking up, and quote the repair first. Put the recommendation and the decision in writing so both sides know the scope.
Should I warranty the sealcoat?
Warranty your application and state that wear, oil, weather and traffic are outside the warranty. Put the reseal schedule and the conditions in writing.
