How often should a commercial parking lot be sealcoated?▾
Every two years for most commercial properties in the Pittsburgh and Allegheny County area. Northeast Ohio properties in the Mahoning Valley and Trumbull County snow belt benefit from an 18-month cycle because of heavier snowfall and more road salt exposure. West Virginia Northern Panhandle properties are generally on a two-year cycle. High-traffic lots and properties with heavy truck movement may need more frequent attention.
What is the best time of year to sealcoat in Western PA?▾
Late spring through early fall, when pavement temperature stays above 50°F and is rising. Sealer needs warm, dry conditions to cure properly, and applying it too late in the season risks an incomplete cure going into the first freeze. In our region that generally means May through September, with early October possible in a warm year.
How long does sealcoating take to dry before cars can drive on it?▾
Plan on 24 hours before vehicle traffic, though foot traffic is usually fine after a few hours. Cure time depends on temperature, humidity, and sun exposure. A shaded lot on a humid day cures slower than an open lot in full sun. We schedule around your operating hours and can phase the work so part of the lot stays open throughout.
Does sealcoating fix cracks and potholes?▾
No. Sealcoating is a protective surface coating, not a structural repair. Cracks need to be filled and potholes patched before sealer is applied, otherwise the sealer simply follows the contour of the damage and the crack reappears within weeks. Any honest sealcoating proposal includes crack filling as a separate line item where it is needed.
Is sealcoating actually worth the money?▾
It is worth it when the pavement is structurally sound and the goal is extending its life. Sealer protects asphalt from oxidation, water penetration, and oil damage, which are the three things that turn small surface problems into full-depth failures. It is not worth it on pavement that is already failing structurally, and we will tell you when a lot has passed the point where sealcoating delivers a return.
