Asphalt Driveway Sealcoating Companies: How to Choose
Updated: Sep 16
Asphalt driveway sealcoating is the single most cost-effective way to protect your pavement from Virginia's brutal freeze-thaw winters, blistering summer sun, and everyday wear from tires and road salt. Consequently, choosing the right contractor and understanding the process can mean the difference between a driveway that looks great for twenty years and one that crumbles apart in five. In this guide, we explain exactly what asphalt driveway sealcoating involves, how the process works step by step, what it costs in Virginia, and every red flag to avoid when hiring a contractor. In addition, we cover the eleven biggest benefits of sealcoating, comparisons to resurfacing and repaving, and fifteen frequently asked questions — so you finish this page knowing more than any competing guide can offer.
Quick answer: Asphalt driveway sealcoating is a protective liquid coating applied over existing asphalt pavement to block water, sunlight, and chemical damage, extending the surface's usable life by several years. Hiring an experienced, licensed contractor rather than attempting a DIY job generally produces a smoother, more durable, and longer-lasting result.
What Is Asphalt Driveway Sealcoating? A Clear Definition
Asphalt driveway sealcoating is the process of applying a thin, protective liquid layer — usually an asphalt-emulsion or coal-tar-based product — directly over existing pavement. As a result, the asphalt underneath stays flexible and resists cracking far longer than unsealed pavement left exposed to the elements. Asphalt itself is a composite material made of mineral aggregate bound together with bitumen (a sticky, petroleum-based binder), and it naturally oxidizes over time when exposed to sun and moisture, as explained in Wikipedia's overview of asphalt. Oxidation is essentially the pavement drying out and losing the oils that keep it pliable, which is exactly what sealcoating is designed to slow down.
Most reputable companies also handle related pavement maintenance work, including crack filling, minor patching, and line striping for commercial lots. Therefore, when evaluating a contractor, it helps to ask whether they offer a full-service approach rather than sealcoating in isolation. A contractor who only sells one service has less incentive to tell you when a different repair — like crack sealing or resurfacing — is the smarter move.
Why Hire Professional Sealcoating Services Instead of DIY
Professional sealcoating services bring commercial-grade sprayers, squeegee machines, and material blends that most homeowners simply cannot access at a hardware store. Furthermore, trained crews know how to read weather windows, since sealant applied too early or during humid conditions often fails to cure correctly and peels within months.
Industry sources such as the Asphalt Institute note that properly maintained pavement, including timely sealcoating, can last significantly longer than neglected asphalt. In particular, regular sealing helps prevent water infiltration, which is the leading cause of pothole formation in colder climates like Virginia's. In contrast, a rushed DIY job with a roller and a box-store sealant often leaves streaks, puddling, and uneven thickness that wears through within a single season.

11 Reasons to Invest in Sealcoating Your Asphalt Driveway
Many guides list a handful of generic reasons to seal a driveway. Below, we go further — eleven specific, practical reasons that cover protection, cost savings, curb appeal, and compliance for both homeowners and commercial property owners.
1. Blocks water infiltration. Water that seeps into cracks expands when it freezes, widening damage until potholes form. Sealcoating closes the surface against that cycle.
2. Shields against UV oxidation. Sunlight breaks down the oils that keep asphalt flexible; sealant acts as sunscreen for your pavement.
3. Resists oil, gas, and chemical stains. A sealed surface sheds automotive fluids instead of absorbing them, which keeps the driveway looking clean.
4. Restores a deep black, freshly paved look. Faded, gray asphalt instantly looks new again after a quality sealcoat application.
5. Extends pavement lifespan by years. Our detailed breakdown of how asphalt seal coating can extend the life of your driveway explains the science behind this in more depth.
6. Saves money versus repaving. Sealcoating costs a fraction of full resurfacing, so regular maintenance avoids a much larger bill later.
7. Prevents pothole formation. Because water is the root cause of most potholes, sealing the surface directly reduces the odds of major structural failure.
8. Simplifies future cleaning. A smooth, sealed surface sheds leaves, dirt, and debris more easily than porous, weathered asphalt.
9. Boosts curb appeal and resale value. A freshly sealed driveway is one of the first things buyers and guests notice.
10. Supports ADA compliance for commercial lots. Smooth, well-maintained pavement reduces trip-and-fall liability for property managers and HOAs.
11. Environmentally responsible when done right. Water-based asphalt emulsion sealants release fewer volatile compounds than older coal-tar formulas.

Signs Your Driveway Needs Sealcoating Right Now
A faded, gray appearance is usually the first warning sign, since fresh asphalt starts out deep black and lightens as oils evaporate. In addition, small hairline cracks, standing water after rain, or a rough, crumbly texture underfoot all suggest the surface has lost its protective barrier.
However, if the driveway already has large potholes or extensive base failure, sealcoating alone will not fix it. In that case, resurfacing may be the better option, and our guide on resurfacing a damaged driveway explains when that step makes more sense than sealing.
Sealcoating vs. Resurfacing vs. Full Repaving
Understanding where sealcoating fits among other pavement options prevents you from overspending or underspending on repairs. Specifically:
Sealcoating — best for surfaces with faded color, minor hairline cracks, or early oxidation. It protects, but does not repair structural damage.
Resurfacing — best when the base layer is sound but the top layer has moderate cracking or shallow potholes. A new layer of asphalt is applied over the existing base.
Full repaving — necessary when the base itself has failed, requiring complete removal and replacement of the pavement structure.
Above all, catching problems early with routine sealcoating is what keeps a driveway in the first category instead of sliding into the second or third.
How to Choose the Right Asphalt Driveway Sealcoating Company
Choosing wisely starts with verifying credentials. Above all, confirm the company carries general liability insurance and, where required, a local contractor license. Otherwise, you could be liable for accidents that happen on your own property.
Ask to see recent local project photos or references, ideally from similarly sized driveways.
Confirm which sealant type they use and whether it meets current environmental regulations.
Request a written estimate that includes crack repair, cleaning, and the number of coats applied.
Check whether a workmanship warranty is included, and for how long it applies.

The Complete Asphalt Driveway Sealcoating Process, Step by Step
Most asphalt driveway sealcoating companies follow a similar sequence to ensure a durable, even finish. Specifically, the process generally includes five stages. For a deeper walkthrough, see our News and Insights on choosing a paving company.
Inspect and clean the surface. The crew checks for cracks and oil stains, then power-washes or blows away debris so the sealant can bond correctly to a clean, dry surface free of loose material.
Fill cracks and repair damage. Technicians apply hot rubberized crack sealant and patch minor potholes before sealing, since coating directly over damage traps moisture underneath and accelerates failure.
Apply the sealcoat evenly. Using a squeegee machine or spray rig, crews apply one to two coats across the surface, working in manageable sections to keep the finish uniform and free of lap marks.
Allow curing before reopening. The driveway stays barricaded for 24 to 48 hours so the sealant fully hardens before vehicles or foot traffic return, preventing tire marks and premature wear.
Inspect the finished surface and schedule maintenance. A reputable crew walks the driveway with you afterward and recommends a reapplication timeline, typically every two to three years depending on traffic and weather exposure.
Because temperature and humidity affect drying time, always confirm the estimated cure window with your contractor before scheduling vehicles or deliveries around it.
Crack filling always happens before sealant is applied, since trapped moisture accelerates pavement breakdown.
How Much Does Driveway Sealcoating Cost in Virginia?
Pricing typically falls between $0.15 and $0.30 per square foot, so a standard 600-square-foot driveway often runs $150 to $400. Meanwhile, larger commercial lots or HOA parking areas cost more due to material volume and equipment needs.
Several factors affect final pricing, including crack repair extent, the number of coats requested, and travel distance for rural properties. If your budget is tight, our guide on achieving sealcoating goals on a budget outlines practical ways to reduce costs without sacrificing quality. For broader regional pavement standards, the Virginia Department of Transportation also publishes maintenance guidance relevant to larger paved surfaces.
Sealcoating Cost vs. Repaving Cost Over Time
A full repave can cost several thousand dollars depending on driveway size, while a sealcoat application typically costs a small fraction of that amount. Therefore, applying a sealcoat every two to three years, at roughly $150 to $400 per application, is dramatically cheaper over a twenty-year period than skipping maintenance and paying for full repaving every eight to ten years instead.
Common Mistakes to Avoid When Choosing a Sealcoating Contractor
One frequent mistake is selecting the lowest bid without checking references or insurance. Consequently, homeowners sometimes end up with thin, uneven coats that peel within a year. Another common error is scheduling work during rainy or cold stretches, since sealant needs stable, warm conditions to cure properly.
Finally, skipping crack repair before sealing is a costly shortcut. Because trapped moisture accelerates pavement breakdown, this step should never be optional, regardless of which contractor you choose. In short, the cheapest bid is rarely the best long-term value.

How often should I sealcoat my asphalt driveway?
Most pavement professionals recommend sealcoating every two to three years, depending on traffic and climate exposure. Skipping this maintenance often shortens the pavement's overall lifespan.
What is the best time of year to sealcoat a driveway?
Late spring through early fall is ideal, since sealant cures best at temperatures between 50 and 90 degrees Fahrenheit. Cold or rainy conditions can prevent proper bonding.
Should I sealcoat my driveway myself or hire a professional?
While DIY kits exist, professional asphalt driveway sealcoating companies use commercial-grade materials and equipment that produce a more even, durable finish. Improper DIY application often leads to premature peeling.
What is the difference between asphalt emulsion and coal tar sealant?
Asphalt emulsion sealant is water-based, dries faster, and is generally considered more environmentally friendly, while coal tar sealant resists oil and gas stains more strongly. Many contractors now favor asphalt emulsion due to environmental regulations.
What common mistakes do people make when choosing a sealcoating company?
The biggest mistakes include selecting the lowest bid without checking references, skipping proof of insurance, and ignoring weather timing. These shortcuts often lead to poor adhesion and early sealant failure.
How long does sealcoating last before it needs to be reapplied?
A properly applied sealcoat typically lasts two to three years before it wears thin from traffic and UV exposure. Reapplying on schedule prevents costly cracking and resurfacing later.
Do I need to close off my driveway during sealcoating?
Yes, the driveway must stay closed to vehicle and foot traffic for at least 24 to 48 hours after application. Most companies mark the area with cones or tape to prevent early use.
What questions should I ask before hiring a sealcoating contractor?
Ask about licensing, insurance, the type of sealant used, expected drying time, and whether a written warranty is included. Reputable asphalt driveway sealcoating companies will answer these questions without hesitation.
Does sealcoating repair cracks in the driveway?
Sealcoating alone does not repair structural cracks; it is a protective topcoat, not a repair material. Cracks must be filled separately before sealant is applied for the best results. For a deeper walkthrough, see our News and Insights page.
Is hiring a sealcoating company worth the investment?
Yes, sealcoating typically costs far less than repaving and can extend pavement life significantly when applied on a regular schedule. Most property owners recoup the cost through avoided repair and replacement expenses.
Can I sealcoat a brand-new asphalt driveway right away?
No, freshly laid asphalt needs time to cure and release excess oils before sealing. Most professionals recommend waiting 90 days to one full year before the first sealcoat application.
Does sealcoating increase my home's resale value?
A well-maintained, freshly sealed driveway improves curb appeal and signals to buyers that the property has been cared for, which can positively influence first impressions during a sale.
Final Thoughts on Asphalt Driveway Sealcoating
In summary, asphalt driveway sealcoating offers a practical, budget-friendly way to protect pavement from Virginia's freeze-thaw cycles, UV exposure, and everyday wear. By verifying licensing, comparing written estimates, understanding the five-step process outlined above, and recognizing which situations call for resurfacing instead, you can hire a contractor with confidence. Ultimately, regular sealcoating every two to three years, paired with timely crack repair, remains one of the most cost-effective ways to extend a driveway's usable life and avoid premature resurfacing.
