Professional Driveway Sealing in Maryland
Protect your driveway investment with professional sealcoating that lasts.
About This Service
Maryland winters are brutal on driveways. Freeze-thaw cycles force water into asphalt and concrete cracks, expanding them with each cycle and accelerating surface breakdown. UV exposure oxidizes asphalt, turning it gray and brittle. Oil and chemical spills penetrate unsealed concrete, causing permanent staining and subsurface damage. Professional driveway sealing creates a protective barrier that defends against all of these forces.
OneNation Pressure Washing provides full-service driveway sealing — starting with professional cleaning to remove all oil, stains, and debris (a step many sealing services skip), followed by crack repair, and finally application of high-grade sealcoat or concrete sealer. We never seal over a dirty driveway. Proper preparation is what makes sealcoating last.
What’s Included
- ✓Freeze-Thaw ProtectionSealing fills and protects the microscopic pores in asphalt and concrete that absorb water. Water that can't penetrate can't freeze, expand, and crack your surface.
- ✓UV & Oxidation DefenseAsphalt oxidizes and becomes brittle under UV exposure. Sealcoating restores the dark, flexible surface that protects against UV degradation and extends driveway life significantly.
- ✓Oil & Stain ResistanceA properly sealed driveway repels oil, fuel, and chemical spills, preventing them from penetrating and permanently staining the surface.
- ✓Always Cleaned FirstWe professionally clean your driveway before any sealing — removing all oil, stains, and debris. Sealing over a dirty surface traps contaminants and causes premature failure.

Our Process
Driveway Cleaning
Professional pressure washing removes all oil, stains, algae, and debris. This step is non-negotiable — sealer applied over contamination will fail prematurely.
Crack Repair
All cracks and significant gaps are filled with appropriate crack filler before sealing to prevent water infiltration and provide a uniform sealed surface.
Sealcoat Application
High-grade asphalt emulsion sealcoat or concrete sealer is applied evenly across the entire surface using squeegee or spray application for optimal penetration.
Cure Time
Sealed driveways need 24–48 hours of cure time before vehicle traffic. We mark the driveway clearly and communicate exact reopening time for your convenience.
Plant & Landscape Safe
We pre-wet and protect every plant, shrub, and lawn bordering the work area before we start, and use biodegradable cleaning solutions that rinse clean. If anything in your landscaping is damaged by our work, we make it right at no cost to you.
Our Guarantee
If you’re not satisfied with the driveway sealing we did, we come back within 7 days and re-clean the area at no charge — no argument, no fine print.
