What Is Sealcoating?
Sealcoating is a liquid protective coating applied directly over asphalt pavement. Think of it like sunscreen and armor rolled into one — it seals out water, blocks UV rays, and creates a barrier against gas, oil, and road salt before they can eat through your pavement.
Here in Delaware County, the freeze-thaw cycle is one of the biggest threats to asphalt. Water works its way into tiny cracks, freezes, expands, and then thaws — over and over again through the winter. Left untreated, those small cracks become potholes, and potholes become expensive repairs. Sealcoating every two to three years stops that process early.
The bottom line: a sealcoat applied today costs a fraction of what a new driveway or repaving job will run you down the road. It's basic maintenance — like changing your oil instead of replacing your engine.
5 Reasons Delco Homeowners Sealcoat Before Winter
- Extends the life of your pavement A properly maintained asphalt surface can last 25–30 years. Without sealcoating, that number drops fast. Regular sealing is the single biggest thing you can do to get the most life out of what you have.
- Stops water damage before it starts Water is asphalt's worst enemy — especially here in Pennsylvania. Sealcoating closes off the surface, so water can't penetrate, pool, or freeze inside your driveway.
- Protects against gas, oil, and road salt The chemicals in vehicle fluids and road salt break down asphalt binder over time, causing the surface to crumble and crack. A sealcoat layer takes the hit so your pavement doesn't have to.
- Gives your driveway a clean, like-new look A fresh sealcoat brings back that deep, dark finish. It's a small thing that makes a big difference — especially if you're thinking about curb appeal or getting ready to sell.
- Way cheaper than repaving A sealcoat costs a fraction of what you'd pay for crack repairs, patching, or a full resurface. It's the kind of maintenance that pays for itself.
How We Do It: Our Sealcoating Process Step by Step
We don't just roll up and spray. Every job starts with a proper inspection and prep — because sealcoating over a dirty or damaged surface is just a waste of everyone's time and money. Here's exactly what we do:
Step 1 — Surface Inspection
We walk the entire driveway or lot before anything else. We're looking at the condition of the existing asphalt, identifying any cracks, low spots, or drainage issues that need to be addressed first.
Step 2 — Cleaning & Surface Prep
Any loose debris, dirt, and vegetation is removed. Oil spots and stains get treated with a primer/degreaser — because sealer won't bond properly over grease. We also edge and trim around borders.
Step 3 — Crack Filling
Cracks are filled and sealed before the coating goes down. Skipping this step just seals problems in. We fill and level cracks so the finished surface is smooth and water-tight.
Step 4 — Sealer Application
We apply professional-grade coal tar or asphalt emulsion sealer using commercial squeegees and spray equipment, depending on the surface. Two coats are applied for full, even coverage.
Step 5 — Line Striping
For commercial lots and driveways where striping is needed, we handle that once the sealer has cured. Fresh, clean lines make a real difference for parking areas and commercial properties.
Step 6 — Cure Time & Cleanup
Most surfaces need 24–48 hours of dry time before you can drive on them — we'll let you know the specifics based on weather and conditions that day. We clean up our equipment and leave your property the way we found it.
Driveway Sealcoating for Delaware County Homeowners
Most of the driveways we work on in Delco are 10, 15, even 20 years old — and a lot of them are in better shape than you'd think, they just need some attention. A clean sealcoat and a few crack repairs can add years to a driveway that might otherwise be heading toward a full replacement.
We work on residential driveways throughout Delaware County — single-car and two-car driveways, circular drives, driveways with steep grades, you name it. Every job gets the same treatment: a proper prep, good materials, and a crew that actually cares about the finished product.

Sealcoating FAQ — Questions We Hear All the Time
How often should I sealcoat my driveway?
Every 2–3 years is the standard recommendation for most residential driveways. If your driveway gets heavy traffic or takes a lot of road salt in winter, leaning toward every two years is worth it. New asphalt should cure for 6–12 months before its first sealcoat.
Can you sealcoat over cracks?
Sealcoating alone won't fill cracks — it'll just coat over them, and they'll come back. That's why we always fill and repair cracks before applying sealer. If your driveway has significant cracking, we'll address that during prep so you get a clean, sealed surface that actually holds up.
What's the best time of year to sealcoat in Pennsylvania?
Late spring through early fall — roughly May through September. Sealer needs warm, dry conditions to cure properly: air temperature above 50°F and no rain for at least 24 hours after application. We won't schedule a job that the weather won't cooperate with.
How long does sealcoating take to dry?
Most driveways need 24–48 hours before you can drive on them. Foot traffic is usually fine after 4–6 hours. We'll give you a specific window based on the conditions the day of your job.
How long does sealcoating last?
A properly applied sealcoat will last 2–4 years depending on traffic, climate, and sun exposure. In Delaware County, where we see hard winters and road salt, we usually recommend budgeting for every 2–3 years.
Do I need to do anything to prepare for the sealcoating crew?
Move vehicles off the driveway the night before if possible. If you have anything stored on the driveway — bikes, garbage cans, basketball hoops — move those off too. We'll handle the rest.
Do you do line striping too?
Yes. We handle line striping and re-striping for commercial parking lots, including standard stalls, ADA spaces, fire lanes, directional arrows, and loading zones. We'll coordinate striping timing with the sealer cure so everything's done in one visit when possible.
