Driveway Materials
Asphalt: Cost: $3-$7 per square foot (installed new). Lifespan: 15-25 years (with proper maintenance). Appearance: black surface (fades to gray over time). Maintenance: seal every 2-3 years ($0.15-$0.25/sq ft DIY or $1-$3/sq ft professional). Crack filling as needed. Pros: affordable flexible (less prone to cracking from freeze-thaw) can be resurfaced (new layer over existing). Cons: requires regular sealing softens in extreme heat (oil stains petroleum products damage it) shorter lifespan than concrete. Best for: moderate climates budget-conscious homeowners and driveways that can be sealed regularly.
Concrete: Cost: $6-$15 per square foot (installed new). Lifespan: 25-50 years (with minimal maintenance). Appearance: light gray (can be stained stamped or exposed aggregate for decorative finishes). Maintenance: seal every 3-5 years (optional but extends life). Minimal ongoing maintenance. Pros: long-lasting low-maintenance strong and durable wide range of decorative options. Cons: more expensive upfront prone to cracking in freeze-thaw climates (expansion joints help) cracks are difficult to repair without being noticeable stains easily (oil rust). Best for: homeowners who want longevity and low maintenance.
Pavers (brick or stone): Cost: $10-$30 per square foot (installed). Lifespan: 25-50+ years. Appearance: individual bricks or stones in a wide variety of patterns and colors. Maintenance: re-sand joints every 2-3 years. Individual pavers can be replaced if damaged. Pros: beautiful and customizable extremely durable individual units can be replaced permeable options available. Cons: most expensive installation requires professional installation weeds can grow between joints. Best for: homeowners who want a premium aesthetic and long-lasting surface.
Gravel: Cost: $1-$3 per square foot (installed). Lifespan: indefinite (with periodic regrading and replenishing). Maintenance: regrade annually add gravel every 2-3 years. Pros: cheapest option good drainage easy to install (DIY-friendly). Cons: gravel migrates (needs edging) not smooth (difficult for wheeled items like strollers and wheelchairs) snowplowing can displace gravel. Best for: rural properties long driveways and budget projects.
Resurfacing vs Replacement
Resurface (overlay) when: The base is still structurally sound. Surface damage is cosmetic (minor cracks small potholes surface wear). For asphalt: an overlay of 1.5-2 inches of new asphalt over the existing surface. For concrete: a concrete overlay (microtopping or stampable overlay) of 1/4 to 2 inches. The driveway is less than 20 years old (asphalt) or 30 years old (concrete). Cost: 40-60% of full replacement.
Replace when: The base has failed (large alligator cracks heaving settling or drainage problems). Multiple large potholes or extensive cracking. The driveway is severely uneven or has poor drainage. Previous resurfacing has been done (you can only overlay once or twice before the total thickness becomes a problem). The driveway is very old (20+ years asphalt 40+ years concrete).
Asphalt resurfacing process: Clean and repair the existing surface. Apply a tack coat (bonding agent). Lay 1.5-2 inches of new hot-mix asphalt over the existing surface. Compact with a roller. Allow to cure (24-48 hours before driving on it).
Concrete resurfacing process: Clean and repair the existing surface (fill cracks apply bonding agent). Apply a concrete overlay or microtopping (1/4 to 2 inches). Can be stamped stained or textured. Allow to cure (24-48 hours minimum).
Cost
Asphalt driveway: New installation: $3-$7/sq ft. Resurfacing (overlay): $2-$5/sq ft. Sealcoating: $0.15-$0.25/sq ft (DIY) or $1-$3/sq ft (professional). Crack filling: $0.50-$1.50/linear foot. Pothole repair: $50-$200 per pothole. Average driveway (600 sq ft): new $1,800-$4,200. Resurfacing $1,200-$3,000. Sealcoating $90-$150 DIY or $600-$1,800 professional.
Concrete driveway: New installation: $6-$15/sq ft (plain). Decorative (stamped stained): $10-$25/sq ft. Resurfacing (overlay): $3-$8/sq ft. Sealing: $1-$3/sq ft (professional). Crack repair: $1-$3/linear foot. Average driveway (600 sq ft): new $3,600-$9,000. Decorative $6,000-$15,000. Resurfacing $1,800-$4,800.
Paver driveway: New installation: $10-$30/sq ft. Repair (replacing individual pavers): $5-$15/sq ft. Re-sanding joints: $0.50-$1.50/sq ft. Average driveway (600 sq ft): new $6,000-$18,000.
Gravel driveway: New installation: $1-$3/sq ft. Regrading: $0.50-$1.50/sq ft. Adding gravel: $1-$2/sq ft. Average driveway (600 sq ft): new $600-$1,800.
Maintenance
Asphalt: Sealcoat every 2-3 years (the most important maintenance task). First seal: 6-12 months after installation (allow the asphalt to cure). Fill cracks promptly (water penetration causes the most damage). Patch potholes immediately (they grow quickly). Clean oil stains (oil dissolves asphalt — use a degreaser and cat litter to absorb). Edge the driveway (prevent grass and weeds from encroaching).
Concrete: Seal every 3-5 years (optional but recommended — protects against stains and freeze-thaw damage). Fill cracks promptly. Avoid deicing salts (calcium chloride and rock salt cause spalling — use sand or kitty litter for traction instead). Clean stains promptly (oil rust and other stains set in if not cleaned). Pressure wash annually.
Pavers: Re-sand joints every 2-3 years (polymeric sand is best — hardens to resist weeds and insects). Pull weeds as they appear. Replace damaged pavers individually. Seal pavers every 3-5 years (optional — enhances color and protects against stains).
Signs you need repair or replacement: Alligator cracking (interconnected cracks that look like alligator skin — indicates base failure). Large potholes (more than 2-3 inches deep or wide). Significant heaving or settling. Poor drainage (water pools on the surface). Extensive surface wear (loose aggregate faded worn). Cracks wider than 1/2 inch (asphalt) or 1/4 inch (concrete).
