What's a good DIY year-round plan for my Ottawa driveway?

A good DIY maintenance plan for Ottawa driveways focuses on four seasonal priorities: spring damage assessment and cleaning, summer crack filling and sealcoating, fall preparation for winter, and winter protection from salt and snow damage. Following this schedule will extend your driveway's lifespan by 5-10 years and prevent minor issues from becoming expensive repairs.

Spring (April-May): Assessment and Cleaning
Start with a thorough inspection after the snow melts. Walk your entire driveway looking for new cracks, potholes, settled areas, or edge damage from snowplowing. Take photos to track changes year over year. Power wash or scrub away winter salt residue, sand, and debris — salt left on surfaces accelerates deterioration. For asphalt driveways, look for areas where the surface appears grey or weathered rather than black, indicating the binder is oxidizing and needs attention. On interlock driveways, check for settled or shifted pavers, weed growth in joints, and areas where polymeric sand has washed out.

Clean oil stains immediately using a commercial degreaser or absorbent material like cat litter for fresh spills. Oil penetrates asphalt and concrete, creating weak spots that crack under freeze-thaw stress. For concrete driveways, inspect for surface scaling (small flakes or chips) caused by winter salt exposure — this indicates the surface needs protection before next winter.

Summer (June-August): Repairs and Protection
This is your main maintenance window when temperatures are consistently warm and dry. Fill any cracks wider than 5mm with rubberized crack filler — clean the crack thoroughly first, apply filler slightly proud of the surface, and smooth with a putty knife. For asphalt driveways that haven't been sealed in 2-3 years, apply driveway sealer on a warm day (above 15°C) with no rain forecast for 24 hours. Clean the surface completely, apply two thin coats rather than one thick coat, and work in sections to maintain a wet edge.

For interlock driveways, replace any damaged pavers and refresh polymeric sand in the joints. Remove old sand, sweep in new polymeric sand, compact lightly, sweep excess, and activate with a gentle water mist according to manufacturer instructions. This prevents weed growth and locks pavers together against frost movement.

Fall (September-October): Winter Preparation
Complete any remaining crack filling before temperatures drop below 10°C — crack filler needs warm conditions to cure properly. Ensure your driveway drains properly by clearing debris from catch basins, extending downspouts away from driveway edges, and regrading soil that may have settled against the driveway. Standing water becomes ice that expands into cracks and joints.

Stock up on winter supplies: sand for traction (better than salt for your driveway), a plastic snow shovel to avoid gouging sealed surfaces, and calcium chloride or magnesium chloride if you must use deicer — these are less damaging than rock salt. Inspect your snow removal equipment and consider rubber cutting edges for snow blowers to prevent scraping the surface.

Winter (November-March): Protection and Gentle Care
Use sand instead of salt whenever possible for traction. When you must use deicer, apply sparingly and choose calcium chloride or magnesium chloride over rock salt — they're less damaging to concrete and asphalt. Never use deicing chemicals on concrete driveways in their first winter.

Shovel snow promptly rather than letting it accumulate and compact into ice. Use a plastic shovel on sealed asphalt to avoid scraping the sealcoat. When hiring snow removal services, specify that metal plow blades should not contact your driveway surface — rubber cutting edges prevent gouging. Remove snow piles from driveway edges before they melt and refreeze, creating ice dams that force water into cracks.

Ottawa-Specific Considerations
Ottawa's extreme freeze-thaw cycles (50+ per winter) make crack filling and sealing critical rather than optional. Water that enters cracks freezes, expands 9%, and widens the crack with each cycle. A 5mm crack can become a 20mm crack in one winter without proper filling.

The deep frost line (1.2-1.5 metres) means any base problems will show up as surface cracking and heaving that you cannot fix with DIY maintenance. If you notice recurring cracks in the same locations or areas that heave and settle seasonally, the base has failed and requires professional reconstruction.

When to Call a Professional
While this DIY plan handles routine maintenance, call a paving contractor for cracks that return in the same location after filling, areas of alligator cracking (interconnected cracks forming a pattern), potholes larger than your fist, or any section that heaves or settles noticeably. These indicate base failure that DIY maintenance cannot address.
