Every spring, thousands of Ontario homeowners consider the question: should I seal my driveway myself or hire someone? DIY is tempting — hardware stores carry sealer kits for $50–$100, and YouTube makes it look easy. But the results can be dramatically different. Here's what you actually need to know before deciding.
DIY Sealing Products
Consumer-grade sealer from Home Depot or Canadian Tire typically contains 20–30% solids (the protective material). Commercial-grade professional sealer contains 35–45% solids, providing significantly better coverage and protection per coat. The difference in product quality alone means professional sealing lasts noticeably longer — even before accounting for application technique.
Labour and Time Requirements
A professional two-person crew can seal a standard driveway in 1.5–3 hours. For a homeowner doing it alone: cleaning takes 1–2 hours, crack filling 30–60 minutes, and sealing (two coats with drying time between) can stretch the project across two days. Equipment rental (squeegee, edging tools) adds cost and effort. And if you make errors, fixing them requires additional time and product.
Quality Differences in Real Results
Professional applications show consistent coverage, straight edges, and even colour. Common DIY issues include: roller marks in the finished surface, uneven colour (thick in some areas, thin in others), drips on sidewalks or garage doors, and sealer applied too thick that takes days to dry and becomes slippery. An experienced contractor knows exactly how much product to apply and how to achieve a clean edge along turf and walkways.
When DIY Makes Sense
DIY sealing can work well for small driveways (under 300 sq ft), homeowners with previous experience, driveways in reasonable condition without significant cracking, and those who genuinely enjoy hands-on projects. If you're careful with preparation and product application, a DIY job can be satisfactory — just expect it to need resealing sooner than a professional job.
When to Call a Professional
Hire a professional for: driveways with significant cracking that needs hot-pour filler, large or complex driveways, any time you want guaranteed results, before selling your home, or when the driveway hasn't been sealed in 4+ years and needs thorough restoration. The price difference — often $100–$200 between DIY materials and professional service — is usually worth it for quality and time savings.
