Sealcoating FAQs

When is sealcoating useful?

Sealcoating is most useful as preventive maintenance on asphalt that is still structurally sound, helping protect the surface from sun, water, and chemical exposure before cracking or base failure sets in.

When is sealcoating a waste of money?

Sealcoating over pavement with significant base failure, widespread alligator cracking, or unaddressed drainage problems is unlikely to help and can mask issues that need repair or replacement instead.

Should cracks be filled before sealcoating?

Yes. Cracks should generally be routed and sealed before sealcoating is applied, not after, so water intrusion is addressed before the protective coat goes down.

How often should parking lots be sealcoated?

Typical cycles range from every one to three years depending on traffic volume, climate exposure, and prior condition. A maintenance contractor can recommend a schedule based on your specific lot.

Can a low sealcoating bid still be a good deal?

Yes, if the scope explains surface prep, crack treatment, material, coats, and cure time in writing. A low price with no written scope, no material details, and same-day pressure is the real warning sign.
