What's included
What a concrete sealing job covers
- Applied only after the concrete has been cleaned — sealing over dirt just traps it underneath
- Protects against oil and rust stains
- Protects against road salt and de-icing salt damage over a Delaware winter
- Helps guard against freeze-thaw cracking
- A repeat service — reapplied every few years, not a one-time job
How it works
Cleaning comes first, always
-
1
The concrete gets cleaned
Sealer only goes down on a clean surface — sealing over dirt or stains traps them underneath, permanently.
-
2
The surface dries fully
Sealer needs a dry surface to bond correctly, the same reason paver work needs dry time between steps.
-
3
Sealer is applied
Once dry, sealer goes on evenly across the driveway, walkway or patio — protecting against stains, salt and freeze-thaw cracking going forward.

Every job has a $400 minimum.
FAQ
Concrete sealing questions
Do I need my concrete cleaned first?
Yes, always. Sealing an unwashed driveway or walkway traps whatever dirt, oil and grime is already on the surface underneath the sealer. Cleaning is a prerequisite, not an optional add-on you can skip.
How long does sealing last?
A few years, and it varies with how much traffic and sun exposure the surface gets — a driveway that sees daily vehicle traffic wears differently than a lightly used walkway. We don't quote an exact year count because it depends on the surface.
What does sealing actually protect against?
Oil and rust stains, road salt and de-icing salt from Delaware winters, and freeze-thaw cracking, where water gets into the concrete, freezes, and expands.
