Custom Deck Construction in Ottawa – Built for Comfort and Ottawa Weather
In Ottawa, a good deck gives you more outdoor space from May through October. This page covers deck design, materials, permits, and timelines. You get skilled carpenters, free home visits, and projects done in 2–4 weeks. KV Construction has built decks across Ottawa for over 15 years.
Homeowners in Burritts Rapids and older Ottawa areas may have different yard sizes. Your deck must follow City regulations to avoid problems. We measure your yard and design your deck to fit.
Odd-shaped yards in older Ottawa areas need special plans. We look at your house, sun patterns, and how you'll use the space. Family dining areas work well at 200–300 square feet. For parties, plan for 300–400 square feet or more.
We check your yard size and note where shade falls during the day. We design the deck to match how you want to live outside.
Right-Sizing Your Deck for Ottawa Homes and Lot Layouts
Ottawa has many freeze-thaw cycles each year. Your deck material must be able to handle this without warping. Pick the wrong material, and you'll need repairs within five years.
We build with pressure-treated wood frames, then add cedar or composite boards. Cedar naturally resists rot and turns silver-gray as it ages. It needs little care. Composite boards never need staining or sealing. They handle minus-30-degree winters without fading.
For top durability, we install hardwood like Ipe or Brazilian mahogany. These strong woods resist water and last many years. We bring material samples to show you, and you choose based on your budget and desired level of care. Learn more about our deck construction services.
Wood vs. Composite Decking – What Works Best in Ottawa's Climate
Property owners near Oxford Mills and rural Ottawa need to know permit rules. The City of Ottawa requires permits for decks over 24 inches high.¹ Rural areas have different rules.
Skipping permits can cause construction stops, fines, and home sale problems. Insurance might not pay claims without permits. We handle all permit work for you.
You need a plan showing the deck location, property line distances, railing heights, and house connection. Railings must be 36 inches high for most decks, or 42 inches if your deck is over 6 feet above the ground. Regular permits take about 5 business days. Fancy designs or old neighborhoods add 2–3 weeks. We make the drawings and work with City inspectors.
Deck Permits and Building Code Requirements in Ottawa
Ottawa families need to know the timing for their deck projects. Book early to avoid the June–August rush. Building season runs from May through October. Spring spots fill up by March.
Your project will have clear steps. Design takes one week. Permits add 1–2 weeks. Building takes 5–10 days. Final inspection takes one day. Most 300-square-foot decks take two weeks total.
The weather also affects timing. Rain delays ground work. Frozen soil before May or after October stops post work. Bigger projects take longer. Your deck can take from one week to two months, depending on size.
Ottawa Deck Construction Timelines – From Design to Completion
Ottawa decks face ice, sun, and rain, and can rot without care. Yearly upkeep makes decks last 15–25+ years. But if you skip care, you can face expensive rebuilds.
Spring checks after snow catch frost damage, loose screws, and cracks. Power wash and stain every 2–3 years. Check for rot and loose boards each spring. Watch for popped nails, cracks, and green algae. Fix these fast.
Winter requires work, too. Clear snow within 24 hours. Never use metal shovels or salt—both damage your deck. Regular care keeps your deck safe.
Maintaining Your Deck Through Ottawa's Four Seasons
Ottawa requires materials that can handle large temperature changes and heavy snow. Freeze-thaw cycles make wood expand and contract. Composite resists water.
Pressure-treated lumber – Cheap, needs yearly staining, lasts 15–20 years
Cedar – Resists rot naturally, turns silver-gray, needs less care
Composite – No staining needed, resists fading, lasts 25+ years
Ottawa winters can crack poor boards. Good installation stops ice damage.
