How to Maintain Your Interlock Pavers for Long-Term Beauty and Durability
Introduction: A Small Amount of Maintenance Goes a Long Way
Interlocking pavers are a fantastic choice for homeowners in Ottawa looking to enhance their property with beauty, function, and durability. With just a few simple maintenance habits, you can keep your interlock surfaces looking fresh, clean, and structurally sound for many years to come — no major repairs required.
1. Keep It Clean: Regular Sweeping & Occasional Washing
Ottawa’s changing seasons bring dust, debris, pollen, and organic matter that can settle between and on top of your pavers.
Recommended care:
- Sweep or blow off your interlock weekly to prevent buildup.
- Give your pavers a light pressure wash 1–2 times per year (spring and fall are ideal).
- For spills or marks, a mild detergent or paver-safe cleaner will usually do the trick.
💡 Tip: Avoid harsh chemicals or pressure washers with narrow jets, as they can affect the surface finish or joint sand.
2. Protect with Sealing (Every 2–3 Years)
Sealing helps protect your interlock from stains, fading, and moisture — especially valuable in Ottawa’s freeze-thaw cycle.
When to seal:
- After installation (we recommend waiting 3–6 months).
- Every 2–3 years depending on exposure and foot/vehicle traffic.
Benefits:
- Enhances the natural colour of the pavers
- Helps prevent stains from oil, BBQs, or fallen leaves
- Reduces water absorption and joint erosion
💡 Tip: Ask your contractor about breathable, penetrating sealers — they work well in Ottawa’s climate and won’t trap moisture.
3. Weed and Ant Control: Stay Ahead of Nature
Even with polymeric sand, Ottawa’s damp springs can sometimes allow weed seeds or ants to try creeping in.
What you can do:
- Gently pull weeds at the root when spotted — never dig or scrape.
- Spot-treat with a vinegar-based natural weed killer.
- Avoid chemical herbicides or ant poisons that can stain or damage the surface.
💡 Tip: Keeping the surface clean and dry is the best way to discourage growth.

4. Be Winter-Wise: Snow & Ice Do’s and Don’ts
Ottawa winters are no joke, and how you care for your interlock during snowy months makes a big difference.
What to do:
- Use a plastic snow shovel or a snow blower with rubber blades.
- Apply paver-safe de-icing products (avoid rock salt or harsh chemicals).
- Clear snow regularly to reduce freeze/thaw expansion.
What to avoid:
- Metal blades, ice picks, or salt with ammonium-based compounds — they can damage the surface or loosen joints.
5. Watch Your Water: Keep Gutters and Drainage Clear
Proper drainage protects your interlock over the long term. Homeowners can help by:
- Making sure gutters and downspouts are clear and pointed away from interlock areas.
- Avoiding pooling water during spring thaw.
- Not hosing water aggressively into joints or corners.
