Why Gaithersburg Homeowners Choose Us
Gaithersburg is one of Montgomery County's largest and most diverse cities, featuring a wide range of residential communities — from planned communities like Kentlands and Lakelands to established neighborhoods like Diamond Farms and Washington Grove. Its suburban character, significant tree coverage, and frequent rain make regular exterior cleaning a priority for local homeowners.
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.

Freeze-Thaw Protection
Sealing 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 Defense
Asphalt 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 Resistance
A properly sealed driveway repels oil, fuel, and chemical spills, preventing them from penetrating and permanently staining the surface.
Always Cleaned First
We 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 Driveway Sealing Process in Gaithersburg
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.
