You have three quotes on your desk. One is cheaper than the others, one is vague, and one uses words you have to look up. Meanwhile, the cracks in your parking lot are getting wider, and the gray, faded surface is the first thing customers see when they pull in.
Picking an asphalt maintenance contractor feels like a price decision, but it is really a scope decision. The right questions show you who understands pavement and who just sells a service. Use this checklist before you sign anything.
1. Which services do you actually perform?
Asphalt upkeep is more than one job. A full-service crew should cover sealcoating, crack sealing, patchwork and repairs, and line painting. Ask which of these they do themselves and which they subcontract.
If a contractor only offers sealcoating, they may recommend sealcoating for every problem. That is worth knowing before you hear their diagnosis.
2. How do you decide between sealcoating, crack filling, and patching?
Each fix solves a different problem. Sealcoat protects the surface from sun, water, and gas spills. Crack filler protects the cracks that already exist. Patchwork handles damage that goes deeper, such as potholes and crumbling edges.
A good answer starts with your pavement’s condition, not their preferred service. Ask them to walk the lot with you and point to what each area needs.
3. What happens to the cracks before sealcoating?
Sealcoat is a surface coating. It is not a crack repair. Cracks are generally treated first, then the surface is coated.
This matters because of what water does. Rain and snow seep into an open crack; the ground underneath softens, and the pavement can sink. Once that happens, the repair gets harder, and the bill gets bigger. Ask what filler they use. Black Dawg uses a hot rubber crack filler, which is the kind of specific answer you want to hear.
4. What products will you use, and can I see the specs?
Sealer quality varies a lot. Cheap sealants may not hold up, and the difference rarely shows until the first season is over. Ask for the product name and the spec sheet for both the sealer and the crack filler.
A contractor who is proud of their materials will hand you the details. If the answer is “we use a good one,” keep asking.
5. How long before we can use the lot again?
Sealcoat usually dries to the touch in about 4 to 8 hours. Full curing typically takes 24 to 48 hours, depending on temperature, humidity, and sun exposure. Cool or damp weather can stretch that timeline.
Ask how they schedule the work around your business, how they block off sections, and how they keep traffic off the surface while it cures. Limiting traffic during curing helps the sealer bond properly.
6. How often will this need to be repeated?
Sealcoating is typically repeated every 2 to 3 years. Busy lots and harsh climates may need it sooner. Crack sealing lasts several years, but it is not permanent.
Be wary of any asphalt maintenance contractor who promises a result that lasts forever. Honest contractors talk in ranges and explain what moves the number: traffic, weather, and how well the pavement was prepped.
7. Is my pavement in good enough shape for this?
Sealcoating helps when the base is structurally sound. If the pavement has deep cracks or potholes, those need to be repaired first, or the coating will not protect much.
This question tests honesty. A contractor who says “your lot needs patching before anything else” has just talked themselves out of an easy sale. That is a good sign.
8. What will be in writing?
Ask for a written scope that lists what will be done, where, and with which materials. Then ask about warranty terms, insurance, licensing, and references from similar properties. Get the answers on paper.
If you manage a commercial property, this is also a liability question. Uneven, cracked pavement is a trip hazard, and a clear scope shows you took reasonable steps to fix it.
FAQ
Can I sealcoat right over cracks?
Cracks are generally treated before sealcoating, because the coating is a surface layer. Ask your contractor how they handle cracks on your specific lot.
Is sealcoating worth it on older asphalt?
It can be, if the base is still structurally sound. Severely damaged pavement should be repaired first.
How do I know it is time to call someone?
Fading color, small cracks, a rough texture, and water soaking into the surface are the usual signs. Acting while cracks are small is usually easier than waiting.
