Is an Interlock Patio Worth It? What Homeowners in Sarnia Should Know
If you’re considering upgrading your outdoor space, an interlock patio might be one of the best investments you can make. Durable, stylish, and built to handle Canadian weather — interlocking stone gives your backyard that finished, high-end look without constant upkeep.
But how much does it cost? How long does it last? And is it really better than poured concrete or wood decking?
Here’s everything Sarnia homeowners need to know before installing an interlock patio in 2024.
What is an Interlock Patio?
An interlock patio is made from pre-cut stones or pavers that are tightly fitted together over a solid base. These pavers can be made of concrete, brick, or natural stone and are available in a wide range of colors and patterns.
They’re known for their strength, flexibility, and classic appearance — perfect for walkways, patios, driveways, and even pool decks.
Benefits of Interlock Patios
- Built to Last: Properly installed interlock can last 30+ years with minimal maintenance.
- Low Maintenance: No staining, sealing, or cracking like concrete. Individual pavers can be replaced if damaged.
- Weather Resistant: Handles freeze/thaw cycles better than poured concrete.
- Customizable Look: Choose your colors, shapes, and patterns to match your home style.
- Boosts Home Value: Adds curb appeal and is a strong selling feature for buyers.

How Much Does an Interlock Patio Cost in Sarnia?

For example, a 300 sq. ft. patio could cost anywhere from $3,000 to $7,500 installed. Premium materials or complex designs can raise the price — but the results are stunning and long-lasting.
How Long Does Installation Take?
Most interlock patios take 3–5 days to complete, depending on size and layout. We handle excavation, gravel base compaction, leveling, edge restraint, and proper drainage to ensure your patio lasts for decades.
Timing may vary during the busy spring and summer season, so it’s smart to book early.
