Your Guide to Maintaining Driveways and Walkways in The Forest City
Your driveway, patio, and walkways are more than just functional parts of your property; they're the first impression your home makes. In a place like London, with its distinct four seasons, these surfaces take a serious beating. From heavy winter snow and ice to summer sun and rain, the constant weather shifts can turn small issues into major, costly problems. Sunken pavers and cracked asphalt not only detract from your home's curb appeal but can also become serious safety hazards.
Many homeowners put off maintenance, worrying about the cost and hassle, only to face a much larger bill for a full replacement down the road. But it doesn't have to be that way. With a proactive approach, you can protect your investment, extend the life of your hardscapes, and keep your property looking pristine. This guide will walk you through the essential maintenance steps for both asphalt and interlock surfaces, helping you understand when to DIY and when to call in the pros.

Understanding the Impact of London's Climate on Your Hardscapes
The biggest challenge for any outdoor surface in Southwestern Ontario is the relentless freeze-thaw cycle. Throughout the winter and early spring, water seeps into tiny cracks in your asphalt or into the base material beneath your interlock pavers. When temperatures drop, this water freezes and expands with incredible force. This expansion widens cracks, pushes pavers upward (heaving), and weakens the entire structure.
When the ice thaws, it leaves behind a larger void, which then collects more water during the next rainfall or melt. This cycle repeats dozens of times each season, leading to common problems like:
- Potholes and Alligator Cracking: Widespread, connected cracks in asphalt that signal foundational failure.
- Sunken or Uneven Pavers: Pavers that sink or become wobbly due to a compromised base, creating trip hazards.
- Drainage Issues: Water pooling on surfaces instead of draining away, which accelerates deterioration and can even lead to water issues around your home's foundation.
Ignoring these early warning signs is what leads to premature failure and the need for a complete, and expensive, replacement.
Proactive Care for Your Asphalt Driveway
An asphalt driveway offers a clean, smooth look, but it requires consistent care to stay that way. The key is to be proactive and address small issues before they escalate. Here’s what you can do:
- Keep it Clean: Regularly sweep away dirt, leaves, and debris. Clean up oil or chemical spills immediately, as they can soften and damage the asphalt binder.
- Seal the Cracks: This is the single most important maintenance task. Small cracks are the entry point for water. Filling them annually with a quality rubberized crack sealer is a simple, inexpensive step that prevents the freeze-thaw cycle from causing major damage.
- Apply a Sealcoat: A sealcoat is a thin, protective liquid layer applied over your entire driveway. It should typically be done every 2-4 years. Sealcoating shields the asphalt from UV rays (which cause it to become brittle), water penetration, and vehicle fluids. It also restores that deep, black finish, instantly boosting your curb appeal.
While cleaning and filling minor cracks can be a DIY job, for widespread cracking, potholes, or professional sealcoating, it's best to seek expert asphalt repair. Professionals have the equipment and high-grade materials to ensure a durable, long-lasting fix.

Maintaining Your Interlock Patios and Walkways
Interlock pavers provide timeless beauty and design flexibility, but their many joints require specific attention to keep them looking their best and functioning properly.
- Weed and Moss Prevention: The joints between pavers are a prime spot for weeds and moss to grow. Regular sweeping helps remove the seeds and organic matter they need to sprout. For existing growth, a stiff-bristled brush or a specialized paver cleaning tool can be effective.
- Re-sanding the Joints: The sand between your pavers is crucial. It locks them together, allows for flexibility, and deters weeds. Over time, rain and wind can wash it away. We recommend topping up the joints with polymeric sand every few years. This special sand contains a polymer that hardens when wet, creating a firm yet flexible bond that is highly effective at preventing weeds and insect infestations.
- Fixing Sunken or Heaved Pavers: If you notice pavers that are no longer level, it's a clear sign that the base beneath them has been compromised by water. This isn't just a cosmetic issue; it's a significant trip hazard. Fixing it properly involves carefully lifting the affected pavers, rebuilding and re-compacting the base layer with the correct materials, and then re-laying the pavers. This is a task that requires skill and the right tools, making it a perfect job for a professional landscaping team.

The Long-Term Value of Professional Maintenance
