Asphalt Sealcoating in West Chester, PA
The Best Defense for Your Driveway or Parking Lot
Sealcoating is a simple maintenance step to help your asphalt last longer. Serving West Chester, Wayne, Malvern, and the Delaware Valley since 1926, Blake’s Paving uses this cost-effective method to protect sound surfaces from sun, rain, and freeze-thaw cycles. If your driveway or parking lot is fading or drying out, sealcoating slows deterioration and prevents expensive repairs. Stay ahead of Pennsylvania weather with professional care that extends your pavement’s life and improves curb appeal.
What Is Asphalt Sealcoating?
A Thin, Protective Coating
Asphalt sealcoating is a thin, protective liquid layer applied over existing pavement. It shields the surface from UV rays, water intrusion, and oxidation, restoring that darker, “fresh-paved” look.
Think of it like applying sunscreen to your skin. It blocks the harmful elements that dry out and brittle the surface, locking in flexibility while keeping the asphalt safe from oil, gas, and weather.
Capabilities vs. Limitations
- Protection: Slows oxidation, reduces water penetration, and resists damage from oil and chemical spills.
- Appearance: Instantly improves curb appeal with a cleaner, richer finish that looks brand new.
- Limitations: It is not a structural fix. It cannot repair potholes, alligator cracking, or drainage issues.
If your asphalt is breaking apart or the foundation is failing, sealcoating will only hide the damage temporarily. That’s why we start with an honest evaluation to ensure it’s the right solution.
Protecting Delaware Valley Asphalt
The Sealcoating Advantage
Asphalt is naturally porous, and without protection, it is vulnerable. Over time, UV exposure dries out the binder, making the surface brittle. Once that happens, water penetrates, freezes, and expands, pushing the pavement apart from the inside.
In West Chester and the surrounding areas, that freeze-thaw cycle is relentless. Sealcoating provides the essential barrier needed to seal surface pores, blocking moisture intrusion and preventing early deterioration before it starts.
Why Sealcoating is a Smart Investment
- Oxidation: Shields the binder from the sun to prevent the graying and drying out that leads to cracking.
- Restores Appearance: Instantly brings back that dark, clean, “fresh-paved” look for homes and businesses.
- Resists Chemicals: Creates a protective layer against gas drips, oil spills, and winter salts.
- Professional Application: We use commercial-grade sealers and precise prep to ensure the coating bonds and lasts.
- Cost-Effective: A fraction of the cost of repaving, extending the life of your current pavement.
Expert Sealcoating Application
Professional Asphalt Sealcoating
We don’t just spray over dirt; we use a rigorous preparation-first process designed to maximize adhesion and longevity. Successful sealcoating starts with aggressive cleaning and vegetation removal so the material bonds to the asphalt, not the grime. We treat oil spots and fill minor cracks to stop water intrusion, then apply a commercial-grade sealer for uniform coverage. With precise application and clear curing instructions, our process restores both the protection and the deep black finish of your pavement.
The Blake’s Sealcoating Standard:
- Deep Cleaning: We clear dirt, debris, and vegetation to ensure the sealer locks directly into the pavement pores.
- Surface Repairs: Oil spots are primed and cracks filled prior to sealing to prevent peeling and water damage.
- Uniform Protection: We apply a consistent, even coat that cures hard for maximum UV resistance and curb appeal.
FAQs About Asphalt Sealcoating
How often should I sealcoat my asphalt driveway in Pennsylvania?
In the Delaware Valley, we generally recommend sealcoating every 2 to 3 years, depending on traffic and weather exposure. For brand new asphalt, you must wait 6 to 12 months for the surface to fully cure before the first application. Sealing too often can cause peeling, while waiting too long exposes the binder to UV damage and oxidation.
Can sealcoating fix cracks and potholes in my parking lot?
No, sealcoating is a protective layer, not a structural repair. While it helps seal small surface voids and slows down oxidation, it will not fix existing potholes, large "alligator" cracks, or crumbling pavement. At Blake’s Paving, we fill minor cracks and patch potholes before sealing to ensure the surface is sound. If the damage is structural, we will honestly recommend repairs or resurfacing instead.
What is the difference between sealcoating and resurfacing?
Think of sealcoating as maintenance and resurfacing as a repair. Sealcoating is a thin liquid layer that protects structurally sound asphalt from sun, rain, and oil. Resurfacing (or overlaying) involves installing a new 1.5 to 2-inch layer of hot-mix asphalt over the existing base to fix a worn surface. We typically recommend sealcoating when your pavement is gray or fading, and resurfacing when it is rough or heavily worn but the base is still stable.
Does Blake’s Paving serve my area in Chester County?
Yes. Blake’s Paving is based locally and serves a 30-mile radius around West Chester, PA. Our primary service area covers the entire Delaware Valley, including Wayne, Malvern, Exton, Frazer, Chester Springs, and surrounding communities. We have been working with local homeowners and businesses since 1926.
Why does my asphalt turn gray, and will sealcoating fix it?
Asphalt turns gray due to oxidation caused by UV rays from the sun. This process dries out the liquid binder (the glue) that holds the aggregate together, making the surface brittle. Sealcoating restores that deep, rich black color instantly and, more importantly, shields the binder from further sun damage to prevent the surface from cracking or raveling.
Do you offer line striping for commercial parking lots?
Yes. In addition to sealcoating, Blake’s Paving provides full parking lot maintenance services for commercial properties. This includes crack filling, pothole patching, and professional line striping to ensure your lot is safe, clearly marked, and compliant. A freshly sealed and striped lot significantly improves the curb appeal of your business.
Is it worth sealcoating an old, cracked driveway?
Honest evaluation is key here. If the asphalt is simply old and gray but stable, sealcoating can extend its life and improve its look. However, if the pavement is "alligator cracked" (looks like reptile scales), crumbling, or has a failing foundation, sealcoating is a waste of money because it won't stop the deterioration. in those cases, we would recommend resurfacing or replacement.
How does sealcoating protect against Pennsylvania winters?
Sealcoating seals the porous surface of the asphalt, preventing water from soaking in. This is critical in the Delaware Valley because trapped water freezes and expands during winter, leading to cracks and potholes (the freeze-thaw cycle). By keeping water out and resisting damage from road salts, sealcoating helps your pavement survive the harsh seasonal shifts.
