driveway sealcoating FAQ for Rochester homeowners

Every 2–3 years for most residential driveways. Annual sealing is usually overkill and can lead to buildup; every 4+ years lets cracks and water damage compound. We'll tell you when you're due and when you can wait a year.

Late May through early October, with daytime highs of 50°F+ and no rain for 24 hours before or after application. We avoid the first two weeks of May (still too cool overnight) and after mid-October (curing risk).

24 hours for cars, 48 hours for trucks or heavy vehicles. Walking traffic OK after 4 hours in warm weather. We cone-off the driveway and leave it that way for 24 hours.

Two reasons. First, watered-down or single-coat product — the $99 "driveway special" companies often dilute sealer 50/50 with water. Second, skipped prep — no crack filling, no edge trimming, no oil-spot primer. A real two-coat job on prepped surface costs $300+ on a small driveway.

Hairline cracks (under 1/8") are sealed by the sealcoat itself. Larger cracks need to be filled with rubberized crack filler first, or they'll reappear within a year. We include up to 25 linear feet of crack filling in standard residential jobs.

No — surface prep is part of our job. We pressure-wash and blower-clean the surface before any sealer touches it. Just please move cars and any movable items off the driveway the night before.

Yes — that's why this matters in Rochester specifically. Sealcoat protects asphalt from water infiltration, which then freezes and expands cracks. A well-sealed driveway can last 25+ years; an unsealed one starts deteriorating in 7–10.

No. New asphalt needs to cure 6–12 months before the first sealcoat — the surface oils have to oxidize out first, or the sealer won't bond. A driveway paved in summer is ready the following season; one paved in fall is ready the following spring. Sealing too early traps oils and shortens pavement life.

No. We just need access to the driveway and a water source for cleanup. Most jobs take 3–5 hours start to finish. Leave us a contact number and we'll text photos when the cone-off is set so you know when to keep cars off it for the next 24 hours.

Coal-tar emulsion is the most durable in freeze-thaw climates and resists oil and gas penetration — it's what most commercial lots use. Asphalt emulsion is lower-VOC and adequate for residential driveways. We default to coal-tar for higher-traffic surfaces and asphalt emulsion when the homeowner prefers a low-odor product.

Untreated oil stains will bleed back through sealer within weeks. We use an oil-spot primer that chemically isolates the stain before the topcoat goes on. Heavy stains may still ghost faintly after one coat; severe contamination sometimes needs a hot-patch instead of a sealcoat.

Sealcoat is a thin protective film, not a structural filler — it cannot bridge cracks wider than a hairline. Unfilled cracks let Rochester freeze-thaw water in, the crack expands, and the surrounding sealer fails within one winter. Filling cracks first with rubberized hot-pour stops the water cycle and is what actually buys you the 2–3 year service life from a sealcoat job.
