Composite Decking

Planning and building a deck should be for long term enjoyment, something that will last and maintain its beauty for decades. One of the ways to achieve this is Composite decking, low maintenance products with extraordinary colours, grains, and durability.

Most composites are made from recycled products and contain a small percentage of organics, thus reducing landfills. More expensive PVC (recycled plastic products) are available and work well as poolside installs. No more sanding or staining.

Interlock and Natural Stone Landscaping

✅ Built to Last – Interlocking pavers withstand heavy traffic, extreme weather, and shifting ground, unlike asphalt or concrete which can crack.

✅ Low Maintenance – Instead of repairing an entire driveway, individual stones can be replaced easily.

✅ Customizable Designs – Choose from a variety of colors, textures, and patterns to match your home’s style.

✅ Boosts Property Value – A well-designed interlock landscape enhances curb appeal and increases home value.

✅ Permeable Surface – Water seeps through the gaps, reducing runoff and preventing flooding.

✅ Better Drainage – Prevents water pooling and keeps your driveway or patio dry.

The Luxury Of Interlock

Some Frequently Asked Questions by Homeowners

Do I need a permit to build a deck in Ontario?

Yes, in many cases, but here's the scoop. A permit is typically required if the deck is attached to your home (ledger bridges are usually required) or more than 24 inches above grade. Smaller decks must still follow local zoning rules such as setbacks and lot coverage but may not need a permit. Requirements vary by municipality, so it’s always best to confirm with your local building department before starting construction or with your builder.

Other important considerations include property setback requirements, railing height requirements, proper footing installations and proper drainage. A permit also ensures that the structure is legal and protects resale value, ensures safety compliance, and prevents issues during inspections or future renovations. There is nothing wrong with financial security and peace of mind

Is composite decking worth it in Ontario?

Composite decking has become a popular choice across Ontario because it performs well in changing weather conditions, resisting moisture, temperature fluctuations, and fading from prolonged sun exposure. While the initial investment is typically higher than traditional wood, homeowners benefit from minimal maintenance, long-term durability, and consistent appearance over time.

Ontario’s climate can be demanding, with freeze–thaw cycles, humidity, and UV exposure all contributing to wear on outdoor materials. Composite decking — particularly PVC-based products — is designed to maintain its integrity under these conditions without cracking, splintering, or absorbing moisture. This makes it a comfortable and safe surface for families, pets, and everyday use.

With entry-level composite lines available at more accessible price points, homeowners can choose from a wide range of options that suit different budgets and design preferences. Higher-end collections offer enhanced colour variation, realistic wood grain textures, and multi-sided finishes that improve both durability and visual appeal, allowing for a customized outdoor space that balances style, performance, and long-term value.

Is there anything wrong with building a deck using wood?

We don't think so. There is nothing inherently wrong with wood decking, and it remains a popular choice due to its natural appearance and lower upfront cost. There is definitely a natural beauty and feel to wood that remains unmatched by manufactured products. Composite is usually selected as an alternative to wood because of very low maintenance. Wood decks do require ongoing maintenance such as staining, sealing, and occasional repairs to prevent rot, splintering, and weather damage. In Ontario’s climate, exposure to moisture, freeze–thaw cycles, and sunlight can shorten the lifespan of untreated or poorly maintained wood. We have seen decks 30 years old that look great, but the truth is that we see more decks that have failed in less time than that.

So, with proper care, pressure-treated lumber and cedar decks can last many years and provide a warm, traditional look. The decision often comes down to balancing initial budget, desired appearance, and willingness to maintain the deck over time.

Today's materials are so advanced that building a deck or other exterior living structure is guaranteed to look better and last longer. Pressure Treated lumber has come a long way, no longer green tinted, it has a beautiful cedar tone (Sienna) finish and easily takes stain.

We can usually restore the most tired of decks we examine, but we do encourage early maintenance to extend the its lifespan. Detailed sanding brings the deck back to life and allows us to apply CUTEK stain, a proven superior marine stain that protects for years.
