Interlock pavers are a Canadian landscaping classic, and for good reason. They’re clean, customizable, and make everything from your driveway to your backyard patio look like it belongs in a design magazine. But here’s the rub: even the best-looking interlock won’t stay that way on its own.
Like anything that lives outdoors year-round in Ontario’s unpredictable climate, pavers take a beating. Between the freeze-thaw cycles, road salt, weeds, UV rays, and your occasional backyard BBQ spill, your pavers are up against it. That’s where sealing comes in.
In this blog, we’ll break down what paver sealing actually does, why it’s so important, and what happens if you skip it. Whether you’re looking to protect your investment or just keep your outdoor space looking sharp, this is one home care tip you don’t want to ignore.
Key Takeaways Before We Dive In
- Sealing interlock pavers protects against weather, UV, stains, and weeds.
- Unsealed pavers are more prone to fading, cracking, and shifting.
- Proper sealing extends lifespan, boosts curb appeal, and reduces maintenance.
- Professional sealing by Level Home Services ensures long-lasting protection and an expert finish.
1. What Is Paver Sealing and Why It Matters
Think of sealing like putting a raincoat and sunscreen on your pavers; it’s a protective barrier between your stonework and the harsh world around it.
At its core, interlock paver sealing involves applying a transparent or semi-gloss protective coating that soaks into the pavers and the sand between them. This layer helps:
- Repel water and reduce erosion
- Guard against UV rays that bleach colour over time
- Prevent oil, grease, or salt stains from penetrating the surface
- Hold joint sand in place and deter weed growth
If you’ve ever seen an old, sun-bleached patio with weeds sprouting through and sand disappearing between the cracks, chances are it wasn’t sealed, or hasn’t been in a long while.
2. Benefits of Sealing Interlock Pavers
Let’s get into the nitty-gritty of why sealing matters:
Preserves Colour and Aesthetic Appeal
Remember how bold and clean those pavers looked on installation day? Sealing helps keep that fresh-from-the-showroom shine by blocking UV rays and dirt buildup. Bonus: sealers come in matte or wet-look finishes, depending on the vibe you’re going for.
Enhances Durability and Lifespan
Unsealed pavers are vulnerable. Over time, moisture seeps in, freezes, and expands, causing chips and cracks. Sealing gives your stonework a fighting chance against Canada’s ever-changing weather.
Prevents Weed and Moss Growth
When the polymeric sand between your pavers stays dry and locked in, weeds don’t stand a chance. Sealing hardens and protects those joints, making it tougher for greenery to push through.
Protects Against Stains and Erosion
Barbecue sauce, red wine, motor oil, life happens. A sealed surface is far less likely to stain permanently. Plus, the sealer keeps rain from washing away the joint sand, so your pavers stay stable.
Helps Resist Shifting and Joint Deterioration
Over time, unsealed joints wash out or loosen. This leads to pavers shifting, settling unevenly, or even becoming trip hazards. Sealing helps “lock” everything in place.
3. What Happens If You Don’t Seal Your Pavers?
We get it; maybe sealing felt optional at the time. But let’s talk about what you’re really risking:
Colour Fading from UV Exposure
Without a protective coat, sunlight slowly leaches the colour out of your pavers. What was once a rich grey or deep red starts to look washed-out and tired.
Weed Growth and Insect Infestation
Sand that isn’t sealed can trap moisture, creating a perfect storm for weeds and creepy crawlers. Before long, your patio becomes more garden than stonework.
Water Infiltration Leading to Shifting or Cracking
Once water gets into unsealed surfaces, freezing temperatures can do serious damage. Cracks, heaving, and shifting are common and costly to repair.
Staining from Oil, Food, and Other Contaminants
Imagine a guest spilling red wine at your backyard party. If the pavers are sealed? No sweat. If not? You’re scrubbing for hours, and the stain might still stick around.
Erosion of Joint Sand and Instability Over Time
Unsealed joints slowly erode with rain and cleaning. The pavers lose their support system and begin to wobble or sink.

4. How Often Should You Seal Pavers?
Here’s the golden rule: every 2 to 3 years, depending on use and exposure. That said, Canadian winters can be particularly tough on pavers, so keep an eye out for:
- Colour fading
- Weeds or moss creeping in
- Loose sand or shifting stones
- Loss of water beading on the surface
Late spring through early fall is the best time to seal, giving the sealer time to cure in mild, dry conditions. Avoid sealing during winter or rainy seasons; Mother Nature doesn’t play nice with wet surfaces.
5. DIY vs. Professional Sealing
Alright, the big question: can this be your DIY project?
Technically, yes. But should you? That’s a different story.
DIY Sealing:
- You’ll need to buy or rent proper equipment (think sprayers, blowers, and rollers).
- Surface prep is key and often overlooked.
- One wrong move and you could trap moisture or apply unevenly, leading to hazing, bubbling, or peeling.
