Hardscaped elements — like patios, walkways, retaining walls, and driveways — are built to last. But in Ontario’s freeze-thaw climate, even the most durable materials need proper care.
Whether you’ve installed a new interlocking patio in Richmond Hill or have an older retaining wall in King City, a few seasonal habits can go a long way in preserving your investment.
Here are practical, proven maintenance tips from the team at Greenbay Northern to help keep your hardscaping beautiful and safe.
1. Keep Surfaces Clean Year-Round
Debris like leaves, soil, and organic matter can stain or encourage moss and weed growth.
✅ Use a broom or blower regularly to clear leaves, especially in the fall
✅ In spring, book a professional property clean-up to remove winter grime
✅ For stubborn stains, a mild pressure wash can refresh most stone or concrete surfaces
2. Reapply Polymeric Sand Between Interlocking Pavers
Interlocking pavers rely on sand to lock joints and prevent shifting. Over time, foot traffic and weather will erode this material.
We recommend having your interlock re-sanded every 2–3 years or as needed. At Greenbay Northern, we specialize in full interlock restoration and cleaning as part of our expertise in hardscaping and what is hard scaping, ensuring your paved surfaces remain stable and visually appealing.
3. Watch for Weeds and Moss
Even with good sealing and sand, some weeds may pop up between stones.
✅ Use a weed torch or natural vinegar spray to remove growth
✅ Avoid harsh chemical herbicides near garden beds or water features
✅ Keep your patio dry and well-drained to discourage moss formation
4. Seal Your Stonework (When Needed)
Some pavers and natural stones benefit from sealing, especially in areas with heavy salt use in winter. Sealers help:
- Protect against stains
- Resist moisture penetration
- Deepen colour for a refreshed look
Greenbay Northern can advise on whether your interlocking driveway or patio would benefit from sealing.
5. Fix Settling or Shifting Immediately
Freezing and thawing can cause settling over time — especially in older patios or walkways.
Look for:
- Uneven or sunken stones
- Trip hazards or pooling water
- Gaps forming between joints
These should be levelled and reset before they worsen. Greenbay Northern handles spot repairs or full-area lifting and resetting as part of our hardscaping services.
6. Avoid Heavy Salt or De-icers
Salt may keep your surface safe in winter, but it also eats away at concrete and can discolour pavers.
✅ Use calcium magnesium acetate (CMA) as a safer alternative
✅ Shovel snow promptly and brush away residue
✅ Protect decorative steps and stone borders with mats or non-corrosive grit
7. Check Retaining Walls for Shifting or Cracks
Retaining walls do heavy lifting, literally. Each season, inspect them for:
- Leaning or bowing
- Cracks between blocks
- Erosion or soil washout at the base
Minor damage caught early is easier and cheaper to repair. Learn more about proper wall care on our retaining wall page.
8. Refresh Edges and Transitions
Over time, borders may shift or fade. Re-edging helps:
- Define lawn-to-patio transitions
- Contain gravel or mulch
- Maintain a clean visual layout
Our garden design and planting team can reshape and edge beds to restore symmetry.
9. Plan an Annual Hardscape Tune-Up
Schedule a full inspection and tune-up each spring to:
- Assess settling and cracks
- Re-sand joints
- Spot-clean surfaces
- Re-edge or re-grade surrounding areas
Greenbay Northern offers seasonal packages for clients in Vaughan and beyond.
Conclusion: Maintenance Protects Your Investment
Hardscaped surfaces are built for longevity — but smart seasonal maintenance makes all the difference. Regular cleaning, joint care, and prompt repairs will keep your walkways, driveways, and patios in top condition year after year.
