Hot-pour rubberized crack sealant for Medford driveways and parking lots — the simplest, highest-payoff preventive maintenance you can do for your asphalt.
Cracks are the number one cause of asphalt failure. Here's the chain: a hairline crack appears in your driveway or lot. Water seeps in. Wet weather pushes it deeper. The next dry spell heats up the surface and the binder oxidizes around the crack. Then the next rain widens the crack a little more. Repeat for a few seasons and that hairline becomes a fissure, then a section of failed pavement, then a pothole. Filling the crack while it's still small breaks that cycle entirely.
Neill Sealcoating provides crack filling throughout Medford — residential driveways across East Medford, the Hillcrest area, Cherry Lane, and the foothills, plus commercial properties along Biddle Road, Stewart Avenue, and the I-5 corridor. We use hot-pour rubberized crack sealant — flexible enough to expand and contract with Medford's hot summers and cool winter nights without re-cracking.

The materials matter as much as the application.
The stuff at hardware stores. Easy to apply, dries in air. Problem: it gets brittle, doesn't expand and contract with temperature, and re-cracks within a couple of seasons.
Heated to 380°F+, poured directly into the crack, bonds to the asphalt as it cools. Stays flexible across temperature swings. Lasts 5-7 years on most surfaces.
If a crack has dirt, grass, or loose material in it, the sealant can't bond. We clean every crack before filling — the unsexy step that determines whether the work lasts.
For wider cracks, we may rout (widen) them slightly to give the sealant a proper reservoir. This sounds counterintuitive but it produces a much longer-lasting fill.
Crack filling typically goes before a sealcoat. The combination — filled cracks + sealed surface — is what gets you 20+ year asphalt life in Medford's climate.
Medford's hot, dry summers expand asphalt and dry out the binder. Cool winter nights contract it. That cycle of expansion and contraction is what opens hairline cracks into wider fissures over time. Add the occasional winter freeze and the wet spring runoff, and an unprotected crack can double in size in a single year.
The good news: Medford's long warm season is also ideal for crack filling work. We can fill cracks any time the pavement is dry and above 40°F, which gives us a long working window — generally March through November. Don't wait until the rainy season starts to think about it.
Before. Sealcoat goes over a properly crack-filled surface. Sealcoat alone won't bridge an open crack — it needs to be filled first.
We walk the driveway or lot, measure the cracking, and identify which cracks need filling versus routing. You get a clear written quote on-site, free and with no obligation.
Yes — crack filling is a standalone service. It's the simplest preventive step you can take if you're not ready for a full sealcoat.
It's black when fresh and stays dark. On unsealed asphalt that's faded to gray, the filled cracks are visible. Combine with sealcoat for a unified appearance.
