Question 1

How often should I seal my asphalt driveway?

Accepted Answer

Most asphalt driveways benefit from sealcoating every 2–3 years. New driveways should wait 6–12 months before the first seal so the asphalt fully cures. Concrete driveways need sealing less often, typically every 3–5 years depending on climate and traffic.

Question 2

What's the best time of year for sealcoating?

Accepted Answer

Late spring through early fall, with daytime temps consistently above 50°F and no rain forecast for at least 24 hours after application. Dry, sunny days in the 70–85°F range produce the best cure. Avoid sealing in fall once nighttime lows drop below 50°F, since the seal won't fully bond.

Question 3

Can I sealcoat a driveway myself?

Accepted Answer

Yes, for asphalt sealcoat the DIY route runs $30–$80 per 5-gallon pail (covers ~250–400 sq ft) versus $0.30–$0.50/sq ft pro-applied. The catch: prep work (cleaning, oil stain treatment, crack filling) is the labor-intensive part, and uneven application leads to streaking. Pro application typically lasts 25–40% longer due to better surface prep and squeegee technique.

Question 4

How long does a sealcoat last?

Accepted Answer

Professional asphalt sealcoat lasts 2–3 years in moderate climates and 1–2 years in extreme freeze-thaw or full-sun environments. Concrete sealer lasts 3–5 years. The lifespan depends heavily on traffic volume, sun exposure, and whether you reapply at the first signs of fading rather than waiting for cracks.

Question 5

Sealcoat vs full repave: when is each right?

Accepted Answer

Sealcoat is preventive: it protects asphalt from UV, oil, and water damage. It can't fix structural problems. If your driveway has alligator cracking (interconnected web pattern), potholes deeper than 2 inches, or large sunken areas, sealing won't help. Those are signs of base failure that need repaving ($3–$7/sq ft for overlay, $5–$15/sq ft for full removal and replacement).

Question 6

How long after sealing can I drive on it?

Accepted Answer

24–48 hours minimum for foot traffic, 48–72 hours for vehicle traffic. Hot weather speeds curing; cold or humid conditions slow it. Avoid sharp turns or parking in the same spot for the first week. The seal is fully cured but still soft enough to mark.
