Our services
Focused asphalt care
A deliberately focused service offering lets one skilled operator spend time on preparation and finish quality instead of rushing between unrelated jobs.
Restorative Two-Coat
For never-sealed, very porous or more weathered pavement when a second coat is appropriate. The second visit is scheduled after the first coat has dried adequately.
Crack Treatment
Appropriate non-structural cracks are cleaned and treated before sealcoating to help limit water intrusion.
Surface Preparation
Debris, loose material and vegetation are removed and edges are detailed so coating goes onto a properly prepared surface.
The difference is in the prep
Built around workmanship, not production volume.
Casco Bay Sealcoating is structured for residential customers who value detail. A one-person operating model keeps responsibility clear: the person you communicate with is accountable for the finished work.

Sealcoating FAQ
Every driveway is different. We would rather give you a realistic recommendation than sell a service that is not appropriate.
Does every driveway need two coats?
No. Previously maintained asphalt in suitable condition may be a good candidate for a single maintenance coat. Never-sealed, very porous or more weathered pavement may benefit from two coats. Final application is based on pavement condition and the coating manufacturer's guidance.
Does the first coat need to dry before a second coat?
Yes. A second coat is applied only after the first has dried adequately under the applicable product and weather conditions. Two-coat work may therefore require a return visit.
How long should I stay off the driveway?
Cure time depends on temperature, shade, humidity and the product used. We provide project-specific instructions after service and will not recommend traffic before conditions support it.
Can every cracked driveway be sealcoated?
No. Sealcoating is maintenance, not structural repair. Pavement with widespread base failure, severe alligator cracking, potholes or major settlement may need repair or replacement instead.
What happens if rain is forecast?
Sealcoating is weather sensitive. If the forecast creates an unacceptable risk, we reschedule rather than compromise the result.
Do I need to be home?
Usually not, provided the driveway is cleared and we have access. We can coordinate the details before the appointment.
