Asphalt Sealcoating
& Maintenance Guide

A properly maintained asphalt surface can last 20 years or more — but neglect cuts that lifespan in half. This guide explains how Atlanta property owners can protect their investment through routine sealcoating, crack filling, and timely repairs, and why the hot, humid Georgia climate makes each step especially important.

Why Sealcoating Matters

Sealcoating is the single most cost-effective way to extend the life of an asphalt driveway or parking lot. A thin layer of coal-tar or asphalt emulsion sealer is applied over the surface, creating a protective barrier against ultraviolet rays, motor oil, gasoline, and water. In Metro Atlanta, where summer pavement temperatures routinely exceed 140°F, UV oxidation breaks down the asphalt binder quickly. Unsealed pavement turns gray and brittle within two to three years, at which point cracks form and water penetrates the base. Sealcoating every two to three years slows that oxidation dramatically, keeping the surface flexible, black, and water-resistant. The process also restores a rich, uniform appearance that improves curb appeal and property value — an important consideration for commercial properties trying to attract tenants or customers.

Crack Filling & Repairs

Even sealed pavement develops cracks over time. Hairline cracks let water reach the stone base beneath the asphalt; in Georgia's freeze-thaw cycles that water expands and widens the crack, eventually producing potholes. Hot rubberized crack filling seals those gaps before water causes structural damage. Potholes and alligator cracking — the interconnected cracks that signal base failure — require full-depth patching or resurfacing. Addressing these issues early costs a fraction of what a full reconstruction would run, so annual inspections are recommended.

Striping & ADA Compliance

Faded striping makes a parking lot look neglected and creates liability risks. Fresh line striping, directional arrows, and ADA-compliant accessible stalls keep traffic flowing safely and demonstrate that the property is professionally managed. Restriping is typically done after each sealcoat so the lines sit on a clean, sealed surface and last longer.

A Simple Maintenance Schedule

For most Atlanta properties, we recommend sealing new asphalt six months to a year after installation, resealing every two to three years thereafter, inspecting for cracks each spring and fall, and restriping whenever lines become hard to see from a parked car. Following this schedule can add a decade to the life of your pavement and save thousands in premature replacement.
