How to Compare Sealcoating Bids
Updated July 6, 2026
To compare sealcoating bids, compare the scope before comparing the price. Check surface cleaning, crack treatment, oil spot handling, sealer type, water dilution, sand loading, number of coats, application method, striping, traffic control, phasing, cure time, and exclusions. Two sealcoating bids can have the same project title but cover very different work.
Sealcoating bids vary because contractors may not be pricing the same job — one bid may include cleaning, crack filling, oil treatment, two coats, sand, phasing, and striping, while another includes only light blowing and one thin coat with none of the rest.
Start by reviewing profiles at Sealcoating Contractors, then compare written scopes line by line rather than the total price alone.
Compare the work area
Confirm each bid covers the same pavement: square footage, drive lanes, parking stalls, driveways, private roads, excluded areas, phased areas, add alternates, and a site map or marked plan. If one contractor measured more pavement than another, the total price may look higher even if the unit value is fair.
Compare surface preparation
Prep is where low bids often cut scope. Look for power blowing, mechanical sweeping, power brooming, scraping debris, vegetation removal, edge cleaning, cleaning around curbs, oil spot treatment, and a dry-surface requirement. A bid that doesn't mention cleaning is incomplete.
Compare crack treatment
Crack treatment can change the price meaningfully.
| Scope item | Why it matters |
|---|---|
| Crack filling included | Reduces open paths for water |
| Hot rubber crack seal | Often used on commercial asphalt cracks |
| Cold pour filler | Common on smaller or lower-budget work |
| Crack cleaning | Helps material bond |
| Crack limits | Defines what is included |
| Alligator cracking excluded | Prevents false expectations |
Compare material, mix, and coat count
Ask each contractor what material they're using. Compare sealer type, water dilution, sand amount, additives, application rate, and number of coats, and whether the same mix is used in all areas. A lower price may reflect a thinner application, more dilution, less sand, or one coat instead of two.
| Item | One coat | Two coats |
|---|---|---|
| Common use | Light maintenance, driveways, budget scopes | Commercial lots, higher-wear surfaces |
| Cost | Lower | Higher |
| Coverage | Less material | More material |
| Risk | May wear faster in traffic areas | More labor and material |
Compare striping, traffic control, and phasing
For parking lots, striping is a major bid difference — check for stall lines, ADA stalls, access aisles, fire lanes, arrows, crosswalks, curb painting, and wheel stops. If striping is excluded, review Parking Lot Striping Contractors.
Traffic control affects commercial pricing: cones, barricades, caution tape, phased closures, resident or tenant notices, emergency access, reopening timing, and weekend or night work. This matters for HOAs, apartments, retail centers, schools, and facilities.
Compare exclusions
Common exclusions include crack filling, oil spot treatment, patching, striping, signs, wheel stops, traffic control, night or weekend work, permits, failed pavement repair, drainage correction, and ADA review. A clear exclusion is acceptable; a hidden exclusion is a problem.
Frequently asked questions
Why do sealcoating bids vary so much?
They vary because contractors may include different prep, crack filling, sealer mix, coats, striping, phasing, and traffic control.
Should I compare sealcoating bids by square foot?
Square foot pricing can help, but only after confirming the same prep, coats, material, and exclusions.
Is a cheaper sealcoating bid always worse?
No. A lower bid may reflect a smaller crew, simpler job, or lower overhead. But a much lower bid should be checked for missing scope.
Should crack filling be part of the bid?
It should either be included or clearly excluded. Cracks are one of the most common scope differences.
Does two-coat sealcoating cost more?
Usually yes, because it requires more material, labor, and time. It may be appropriate for many commercial lots.
