Introduction: Why Interlock Needs Extra Care
Interlock patios, driveways, and walkways are some of the most beautiful features you can add to your property. They boost curb appeal, enhance outdoor living spaces, and, when maintained properly, can last for decades. But without regular care, interlock can lose its charm quickly.
Weeds start sprouting between the joints. Pavers shift and sink. Colours fade from sun, salt, and snow. Before long, your once-stunning interlock looks tired and neglected.
The good news? With the right maintenance and professional sealing, you can extend the life of your interlock surface and keep it looking brand new. At No Limit Sealing, we specialize in restoring and protecting interlock across Vaughan, Richmond Hill, Markham, and the GTA.
Common Problems with Interlock Surfaces
Homeowners often face the same issues with interlock patios and driveways:
- Weed Growth: Dirt and moisture between pavers create the perfect environment for weeds and moss.
- Shifting Stones: Heavy traffic or freeze-thaw cycles cause pavers to sink or move out of place.
- Joint Sand Washout: Rain and snow gradually wash away sand between pavers, leading to instability.
- Fading Colours: UV rays and road salt dull the natural vibrancy of stone and brick.
- Stains: Oil, grease, and rust can permanently discolour unprotected surfaces.
👉 If you live in Markham or Vaughan, these issues are especially common due to heavy snow removal and salt use.
Step 1: Regular Cleaning
Keeping your interlock clean prevents bigger problems.
- Sweeping: Regular sweeping stops dirt from breaking down joint sand.
- Power Washing: A deep clean removes stains, moss, and buildup.
- Stain Treatment: Oil and grease should be treated quickly before they seep in.
Pro Tip: Don’t overdo power washing — blasting joints too aggressively can remove sand. At No Limit Sealing, we use professional-grade washers and adjust pressure for the safest results.
Step 2: Joint Sand Replacement
One of the most important steps in interlock maintenance is replacing the sand between pavers.
- Polymeric Sand: Unlike regular sand, polymeric sand hardens when wet, locking pavers in place.
- Prevents Weeds & Ants: Stops weed growth and deters insects.
- Stabilizes Surface: Reduces shifting and sinking.
In Richmond Hill and Aurora, where winter freeze-thaw cycles are tough, polymeric sand is essential to keep interlock stable.
Step 3: Sealing for Protection and Beauty
Sealing is the key to extending the life of your interlock.
Benefits of Sealing:
- Enhances Colour: Restores faded stone to its original vibrancy.
- Protects Against Salt: Shields surfaces from Ontario’s harsh de-icing chemicals.
- Prevents Stains: Stops oil, rust, and grease from penetrating.
- Locks in Joint Sand: Keeps polymeric sand in place for longer.
Types of Sealers for Interlock:
- Penetrating Sealers: Offer invisible, long-lasting protection.
- Acrylic Sealers: Provide a glossy “wet look” that makes colours pop.
At No Limit Sealing, we help homeowners choose the right sealer based on their goals — whether it’s long-term durability or enhancing aesthetics.
Step 4: Professional Repair & Re-Levelling
Sometimes interlock needs more than cleaning and sealing.
- Re-Levelling: If pavers have sunk, they must be lifted and reset.
- Edge Restraint Repair: Broken or loose edges can lead to spreading.
- Paver Replacement: Damaged stones can be swapped out without replacing the whole surface.
Instead of expensive full replacements, our repair services save homeowners across Vaughan and Toronto thousands of dollars.
FAQs About Interlock Maintenance
Q: How often should interlock be sealed?
A: Typically every 2–3 years, depending on traffic and exposure to salt.
Q: Can I seal interlock myself?
A: DIY products exist, but they often peel or fade quickly. Professional-grade sealers last longer and provide stronger protection.
Q: Does sealing make interlock slippery?
A: Not if applied correctly. We use the right amount to protect without creating slick surfaces.
Q: How do I know if my interlock needs re-sanding?
A: If sand washes out easily or weeds are growing, it’s time for joint replacement.
