Driveway Sealing Services in Ottawa

Protecting asphalt after it has been laid is just as important as proper driveway installation. Ottawa’s freeze-thaw cycles, road salt, moisture, and summer sun can cause asphalt to fade, oxidize, and crack over time. Professional driveway sealing adds a protective barrier that helps repel water, oil, fuel, UV rays, and other contaminants that accelerate pavement deterioration.

At WCI, we combine thorough surface preparation with professional-grade asphalt sealer to deliver complete, even coverage and long-lasting protection. Our proven process restores your driveway’s rich black finish while helping extend the life of your asphalt for years to come.

Our Residential Paving Services

Residential Driveway Sealing

Protect your asphalt driveway from Ottawa’s demanding freeze-thaw cycles, road salt, moisture, UV exposure, and everyday vehicle traffic. WCI applies professional-grade asphalt sealer to create a durable protective barrier that helps slow oxidation, reduce water penetration, and preserve the flexibility of the pavement. The finished application also restores the driveway’s rich black appearance and improves overall curb appeal.

Commercial Asphalt Sealing

WCI provides asphalt sealing for commercial parking lots, private roads, multi-unit properties, and other high-traffic paved surfaces. Each project is assessed based on pavement condition, traffic volume, drainage, and exposure to oil, fuel, salt, and weather. Our commercial sealcoating process helps reduce surface deterioration, improve appearance, and extend the service life of the asphalt while minimizing long-term maintenance costs.

Asphalt Crack Sealing

Cracks allow water to penetrate beneath the asphalt surface, where it can weaken the base and worsen during repeated freeze-thaw cycles. Asphalt crack sealing uses a flexible sealant to close active cracks and joints, helping limit moisture infiltration and prevent further pavement movement. This service is especially valuable for protecting newer asphalt and slowing the progression of existing damage.

Driveway Crack Filling

Smaller, non-moving cracks can often be filled before the driveway is sealed. WCI cleans and prepares the damaged areas, removes loose material, and applies a compatible crack filler to improve surface continuity. Filling these cracks before sealcoating helps create a smoother finish, improves sealer coverage, and reduces the likelihood of water entering the pavement structure.

Asphalt Sealcoating

Our asphalt sealcoating service involves the professional application of a high-quality protective coating across the prepared pavement surface. The sealcoat helps shield asphalt binder from oxidation, sunlight, moisture, road salt, fuel, oil, and chemical contaminants. Proper application provides consistent coverage, restores the deep black finish of the asphalt, and supports a more effective preventative maintenance plan.

Concrete Sealing

Concrete driveways, patios, walkways, garage floors, and other surfaces can benefit from professional sealing. A penetrating or topical concrete sealer helps reduce water absorption, staining, salt penetration, freeze-thaw damage, and surface scaling. The correct sealer is selected based on the concrete condition, location, finish, and desired level of protection, helping preserve the surface without changing its natural appearance unnecessarily.

Driveway Sealing FAQs

The top layer of your pavement can be weatherproofed by applying  protection called sealcoating on top of it. Similar to how you would imagine staining and sealing a wooden fence, think of seal coating your asphalt. The addition of this top-coat layer offers defence against degradation, UV radiation from the sun, and oxidation, all of which lead to cracking. The sealcoat will wear away, leaving the underlying pavement undamaged and in excellent shape, as opposed to your actual pavement eroding.

Your driveway or parking lot will last longer if you add a sealcoat to the top layer of the pavement. Small cracks in cracked asphalt should be filled with asphalt crack filler to prevent them from growing larger in the future. By caulking these cracks, you can help prolong the lifespan of your asphalt by preventing water from leaking through to the foundation material.

In addition to adding a protective layer, sealcoating will bring the surface back to a brand-new, stunningly black appearance. It is a very simple and inexpensive technique to transform your driveway from boring to gorgeous.

Professional driveway sealing helps protect asphalt from moisture, UV rays, oxidation, road salt, oil, fuel, and everyday traffic while restoring its appearance.

Additional benefits include extending the lifespan of your driveway, slowing the development of cracks, improving curb appeal, reducing long-term maintenance costs, and preserving the flexibility of the asphalt. When performed regularly, sealcoating is one of the simplest ways to keep your driveway looking its best and performing well for years.

Driveway sealing protects asphalt by creating a protective barrier against water, UV rays, road salt, oil, fuel, and everyday wear. It also restores the driveway's rich black appearance and helps slow the natural aging process of asphalt.

Although sealcoating does not strengthen the structural base of the driveway, it helps reduce surface deterioration, slows oxidation, minimizes moisture penetration, and extends the lifespan of the pavement when performed as part of a regular maintenance program.


 

Unfortunately, sealcoating might not be your best option if your asphalt parking lot is old, damaged, and has previously been neglected. Prior to degradation and damage, asphalt is sealed to avoid further deterioration. To find out the condition of your current lot and whether sealcoating may help you extend the life of your lot, our professionals can provide you with a free evaluation.

If your parking lot is older and has already had seal coating, a crack fill process will need to be applied where necessary to delay the deteriorating process before a fresh layer of sealcoat is installed.

Even the lesser jobs can seem easy enough to complete on your own, but we have observed that the outcomes are frequently unsatisfactory. For seal coat projects, we advise that you always use a professional. A professional not only possesses the necessary skills and expertise, but also the right tools to do the task at hand.

As with any type of construction, performing routine maintenance as directed increases both the structure's lifespan and your overall financial savings. When your asphalt is properly cared for, you won't have to pay exorbitant repair or replacement fees for a very long time. However, damage and deterioration are imminent if you ignore the surface and fail to adhere to a suitable maintenance programme, and the associated expenditures might be high.

Yes. If our representative determines that the condition of your driveway precludes sealcoating and routine maintenance, we can overlay it or completely remove and replace it.

Your driveway starts to deteriorate as soon as it is installed due to the sun's UV rays, water, ice, fuel, and oil. Stones of varying sizes, sand, and asphalt cement make up asphalt pavements. Pavement becomes brittle, grey, and broken as a result of the sun's UV rays weakening the asphalt cement holding the stones and sand together. Since asphalt cement is also a petroleum product, it is broken down by gasoline and oil, causing stones to become loose and potholes to form

Regular sealcoating will protect your pavement from UV rays, stop gas and oil leaks, keep water and ice out, and improve its appearance. Asphalt pavements can be doubled in life with sealcoating, which eliminates the need for pricey maintenance and replacement.

Most asphalt driveways should be resealed every 2 to 3 years, depending on traffic levels, weather exposure, and the overall condition of the pavement.

Driveways that receive heavy vehicle traffic or frequent exposure to sunlight, road salt, and harsh weather may benefit from more frequent maintenance. Rather than following a strict schedule, it's best to monitor the condition of your driveway for signs such as fading, surface wear, or increased water absorption. A professional inspection can help determine the right time to reseal your asphalt.

In most cases, you should wait 24 to 48 hours before driving on a newly sealed driveway. The exact curing time depends on the type of sealer used, temperature, humidity, and weather conditions.

While the surface may feel dry to the touch within a few hours, it needs additional time to fully cure and harden. Driving on the driveway too soon can leave tire marks, damage the finish, or reduce the effectiveness of the sealcoat.

At WCI, we'll let you know when it's safe to use your driveway based on the weather conditions and the products applied.
