Asphalt oxidizes and dries out from UV exposure, and fine cracks let water in that freezes and turns into a pothole within a season or two. A sealcoat slows that oxidation and fills the smallest cracking, but works best once any larger cracks are treated first.
Sealcoat slows the freeze-thaw cycle that turns small cracks into potholes.
Unsealed asphalt dries, greys and becomes brittle faster under sun exposure.
A sealed surface resists staining from vehicle fluids better than raw asphalt.
We check crack size and surface wear on site, then confirm a written price before booking. We won't seal over a crack that needs attention first.
Larger cracks are treated before sealcoating, so the sealcoat doesn't just flex and crack along the same line.
Sealcoat goes down once the surface is fully dry so it cures evenly instead of lifting.
Loose stone, dirt and oil residue are pressure washed off before any sealcoat is applied.
We work carefully around driveways, walkways and landscaping for the full visit.

Capital Wash & Seal provides professional asphalt sealing throughout Ottawa and the surrounding area. Homeowners and property managers reach out when a driveway or lot is starting to grey and dry out, shows fine surface cracking, or needs protection before another Ottawa winter of freeze-thaw cycling and de-icing salt. Asphalt, along with concrete and interlocking pavers, is one of the most common driveway and lot surfaces across the region, and each material takes a different sealing approach. Sealcoating fills fine cracking, slows UV oxidation and gives asphalt a fresh, uniform dark finish, and it works best paired with crack treatment on any larger cracks first. Typical asphalt sealing costs in the Ottawa area run about $0.35 to $0.65 per square foot, confirmed for your driveway or lot in a written quote before work begins.
Yes, cracks that need treatment are addressed before sealcoat goes on, since sealing over an untreated crack usually just cracks again along the same line.
Cure time depends on the product and weather, and we confirm the specific timeline for your driveway or lot in your written quote so you know exactly when it is ready for traffic.
Most residential driveways and commercial lots in the Ottawa area are resealed every two to three years, depending on traffic volume and sun exposure.
Yes, we work on both residential driveways and larger commercial lots and lanes.
Sealcoat needs dry, mild weather to cure properly, so most jobs happen from late spring through early fall.
Yes, as long as the surface is cleaned first and any cracking underneath is treated. A worn sealcoat layer doesn't need to be stripped before a fresh coat goes on.
We sealcoat existing asphalt surfaces. Gravel driveways need a different treatment entirely, and we can talk through options if you're not sure which one you have.
