J & A Sealcoating and Paving
Q & A Questions
What is sealcoating?
Sealcoating is a protective layer applied to asphalt to guard against sun, water, salt, oil, and Pittsburgh’s freeze‑thaw cycles. J & A uses commercial‑grade sealer for long‑lasting results.
Why should I sealcoat my driveway or parking lot?
Sealcoating keeps asphalt looking fresh, prevents cracks, slows deterioration, and saves money over time. It’s the most affordable way to extend pavement life.
How often should I sealcoat?
Most Pittsburgh driveways need sealcoating every 2–3 years due to weather conditions. At J & A Sealcoating and Paving we offer a 5-7 year warranty.
How long does sealcoat take to dry?
Foot traffic after 24 hours; vehicle traffic after 48. Dry time may vary based on weather.
Do you fill cracks before sealing?
Yes. J & A cleans and fills cracks before applying sealer. Sealcoat alone does not repair cracks.
Asphalt Paving FAQ
What’s the difference between paving and sealcoating?
Paving installs new asphalt or replaces damaged pavement. Sealcoating protects the asphalt you already have. J & A provides both services.
How long does new asphalt last?
With proper maintenance, asphalt can last 15–25 years.
How thick should asphalt be?
Residential driveways: 2–3 inches
Commercial lots: 3–6 inches
J & A will recommend the right thickness for your property.
When can I drive on new asphalt?
Typically 3–7 days depending on temperature and weather.
What causes asphalt to crack?
Freeze‑thaw cycles, water penetration, heavy loads, and aging. Regular maintenance prevents most issues.
