Expert craftsmanship. Beautiful, durable decks tailored to your home.

Detail of deck construction where the deck meets the foundation

Here in Ottawa a custom deck is so important for maximizing the summer months. A good deck gives you more room to enjoy your home, with your family or for entertaining.

Here we'll cover deck design, materials, permits, and timelines. KV Construction is a team of skilled carpenters with over 15 years of experience available now to get your deck projects done in 2 weeks.

Wood vs. Composite Decking What Works Best in Our Climate

Decks are exposed to cold winters, hot summers, and all kinds of precipitation. We see multiple freeze-thaw cycles each year. Your deck material must be able to handle this without lifting, cracking, or warping.

Normally we build with pressure-treated wood joists supported by a post on concrete footing. Decking is a style and budget consideration for the owner. Cedar and Ipe naturally resist rot and offer timeless style. These wood finishes need a little extra care but will last 10-15 years.

A great alternative is composite or vinyl. Composite is a resin or plastic product that contains wood. These decks have the look of wood but are more durable and last 20-30 years. Composite boards never need staining or sealing.

Vinyl is just as durable and easier to install. It sits on a plywood surface. We work with specialized contractors who lay and glue it in place.

Deck Permits and Building Code Requirements in Ottawa

Homeowners from Centrepointe to Greenboro love their outdoor space but aren't usually up to speed on permit rules. Yes, decks normally require a permit; the City of Ottawa requires permits for decks over 24 inches high¹. This applies to decks attached to the house, connecting a detached garage, or as a stand alone structure. Deck permits take about 5 business days.

Ottawa Deck Construction Timelines

We've built so many decks over the years that these are like second nature. Design is quick, but permits are usually 5 days. Building the deck will take 2-5 days, and staining is another 1-2 days, and we will plan a final inspection for the last day. Expect a 300-square-foot deck to take two weeks in total.

The weather can affect timing. Decks are great summer projects, but rain can delay the project, especially if stain is required.

Maintaining your Deck for Four Seasons

We face ice, sun, and rain, sometimes in a single day. Decks are big, flat surfaces, and very exposed all year. Yearly upkeep helps wood decks last 15–25+ years.

Over the winter clear snow on your deck. Avoid using metal shovels or salt, as both damage your deck.

Take a walk around the deck in the spring to check for wear, damage, loose screws, and cracks. Wood decks can be power washed on a low pressure setting to remove algae, and then stained. Check for rot and loose boards each spring. Fix these issues and replace boards or hardware as necessary, and you'll be ready to enjoy your deck for another summer.

If you're considering replacing your deck, or if you just have some questions about your project, give us a call today.
