Question 1

How much does parking lot resurfacing cost per square foot?

Accepted Answer

Overlay: $1.25–$3.00/sq ft. Mill-and-fill: $2.50–$5.00/sq ft. Full replacement: $4.00–$8.00/sq ft. A 50,000 sq ft lot costs $62,500–$400,000 depending on method.

Question 2

How do I know if my lot needs resurfacing vs. full replacement?

Accepted Answer

If distress affects less than 25% of the surface with a sound base, overlay works. Over 40% alligator cracking or base failure means full replacement. Core sampling confirms base condition.

Question 3

How long does parking lot resurfacing take?

Accepted Answer

Overlay: 2–4 days for a 50,000 sq ft lot. Mill-and-fill: 3–6 days. Full replacement: 7–14 days. Phased construction keeps 50–75% of spaces available.

Question 4

How often should a parking lot be resurfaced?

Accepted Answer

With proper maintenance (sealcoat every 2–3 years, crack fill annually), 20–25 years. Without maintenance, 12–15 years. Timely resurfacing at year 15–18 is most cost-effective.
