Your driveway is made up of sand, stone, and bitumen — the thick black liquid that holds everything together and gives asphalt its durability and flexibility.

There are several manufacturers, but Andy’s Asphalt Sealing exclusively uses MC Asphalt’s professional-grade driveway sealer — the same product trusted by asphalt contractors across Ontario.

Sealing your driveway prolongs its life significantly. It protects the asphalt from the elements, slows the breakdown of the binding agents, and keeps your driveway looking great for years longer than an unsealed surface.

Your driveway is made up of sand, stone, and bitumen — the thick black liquid that holds everything together and gives asphalt its durability and flexibility.

Over time, the bitumen evaporates out of the asphalt and wears off the surface. As the asphalt dries out, sand begins to loosen and work its way out, followed by the stone aggregate — leaving a pock-marked, deteriorating surface that becomes increasingly expensive to repair.

There are two main types: water-based sealers, which are available at hardware stores like Home Depot for DIY application, and oil-based sealers, which are used by professional asphalt contractors like Andy’s.

Oil-based sealer is the superior product. It contains the same chemical properties found in the asphalt itself, making it flexible year-round and far less likely to crack. Oil-based sealer is absorbed into the top layer of the asphalt, acting as a binder for the sand and stone components and prolonging the life of your driveway. There are no water-based products in asphalt — oil-based is the original formula.

Yes — when first applied, the sealer has a shiny finish. Depending on sunlight, dust, and traffic levels, it will transition to a flat black appearance within 3 to 4 weeks.

Sealing won’t completely prevent cracks, but it significantly reduces the rate at which they appear by keeping the asphalt flexible and protected from the elements.

Depending on your environment and traffic levels, sealer lasts 2 to 3 years. Even when it has mostly worn off the surface, it remains in the top layer of asphalt, continuing to protect from below.

We recommend sealing every 2 to 3 years for optimal protection and appearance.

We don’t offer a formal warranty, but we stand behind our work 100%. If there is ever a problem, we will return to fix the issue or re-spray the driveway at no charge to you.

Yes. We perform small asphalt repairs using cold patch product and cold pour crack filling for residential driveways.

We apply one coat — and that’s all that’s needed. More is not better. One coat is the industry standard recommendation, and it’s how all our jobs are quoted.

The sealer is dry to the touch approximately 20 minutes after application. You can walk on it after about 6 hours. For vehicle traffic, we recommend waiting 24 to 48 hours to allow proper curing.

Andy has been in the asphalt sealing business for 15 years, with trained employees carrying 5 to 10 years of experience each. Andy’s is fully insured, WSIB certified, and has built its reputation on quality workmanship and repeat customers throughout Milton and the Halton Region.
