Spring Is Deck Season in Kamloops — But Plan Before You Dig
Every spring, the same thing happens across Kamloops neighbourhoods: the snow clears, the sun comes back, and homeowners start eyeing their backyards and thinking about what could be out there. A deck, a covered patio, an outdoor kitchen, a pergola — the possibilities are real, and in a climate like the Thompson region's, a well-built outdoor living space gets serious use from May through October.
But a deck is more than a weekend project. Done right, it adds genuine value to your home and gives you years of reliable outdoor living. Done poorly — with undersized footings, the wrong materials for the climate, or skipped permits — it becomes a liability. Here's what to think through before you start.
Permits: Yes, You Need One
This is the piece most homeowners underestimate. In Kamloops, any deck that is more than 600mm (about 24 inches) above grade, or that is attached to the house, requires a building permit from the City of Kamloops. The permit process involves submitting drawings that show the deck's dimensions, the framing plan, footing specifications, and how it attaches to the home's structure.
Permits exist for good reasons. A deck that isn't permitted and doesn't meet code can create real problems when you go to sell your home — and more importantly, an improperly built deck is a safety risk. Ledger board connections and footing design are the two areas where shortcuts most commonly cause failures.
If you're working with a licensed contractor, they'll pull the permit and manage the inspection process for you. If you're doing the work yourself, plan two to three weeks for permit processing before you want to break ground.
Footings: The Most Important Part Nobody Sees
Kamloops sits in a semi-arid climate, but that doesn't mean frost isn't a factor. The frost depth in the Thompson region is significant enough that deck footings need to extend below the frost line — typically 4 feet or more — to prevent the seasonal movement that causes decks to heave, shift, and pull away from the house over time.
The two main footing options are:
- Concrete poured footings — the standard approach, where forms are placed in dug holes and concrete is poured. Solid, predictable, and what most inspectors will want to see for attached decks.
- Helical piers — steel screw piles driven into the ground by machine. Faster to install, no digging or waiting for concrete to cure, and increasingly common for larger or more complex deck projects.
The footing size and spacing depend on the load the deck will carry — the deck's size, the species and spacing of the beams and joists, and what you plan to put on it (a covered structure, a hot tub, and outdoor furniture all add load). A proper structural design ensures you're not guessing.
Choosing Your Decking Material
This is where most of the style decisions happen, and where it pays to think long-term. Kamloops's climate — hot, dry summers and cold winters — is actually a good environment for most decking materials, but there are still meaningful differences.
Pressure-treated lumber remains the most common choice for its cost and availability. It works well for the structural components (beams, joists, posts) regardless of what you choose for the deck surface. For the decking boards themselves, it's functional but requires regular sealing and staining to maintain appearance and prevent checking and graying.
Cedar is a popular upgrade from pressure-treated for the decking surface. It's naturally rot-resistant, lighter, and has better dimensional stability. It still needs maintenance, but it weathers more gracefully and is easier to work with.
Composite decking — products like Trex, Fiberon, or TimberTech — has come a long way. Modern composites are genuinely low-maintenance: no staining, no sealing, and no splinters. They're more expensive upfront but typically have 25-year warranties and hold their appearance well. In Kamloops's dry climate, composites perform particularly well compared to wetter coastal regions where moisture can be an issue for some products.
Hardwood decking (Ipe, Cumaru, or similar tropical species) is extremely durable and visually striking. It's also significantly more expensive and requires proper acclimatization before installation. For homeowners who want a premium look with real wood, it's worth considering.
Structural Framing: What Goes Underneath Matters
The decking surface is what you see, but the framing underneath determines how the deck performs over time. Key framing considerations for Kamloops decks:
- Beam sizing must match the span. Undersized beams deflect over time, causing the deck to feel bouncy and eventually leading to structural issues.
- Joist spacing affects both stiffness and the decking material you can use. Composite manufacturers often specify maximum joist spacing; using wider spacing voids warranties.
- Ledger board connection — where the deck attaches to the house — is one of the most critical details. The ledger must be attached to the home's structural framing (not just sheathing), with proper flashing to prevent water intrusion behind the board. Ledger failures are the most common cause of deck collapses.
- Post-to-beam connections should use proper hardware rated for the load, not just toenailed lumber. Metal post caps and beam hangers are inexpensive and dramatically improve connection strength.
Covered Structures: Pergolas, Roofs, and Screen Rooms
Many homeowners want more than an open deck — they want shade, weather protection, or a true outdoor room. Kamloops summers are sunny enough that a pergola or shade structure genuinely extends the usable hours outdoors. A covered roof over the deck makes the space usable even during the occasional rainy week in May or September.
Covered structures add cost and complexity to the permit process but are absolutely achievable. The key is designing them as part of the project from the start rather than adding them later. Tacking a roof onto a deck that wasn't designed for the additional load requires retrofitting footings and structure — expensive compared to planning it correctly upfront.
if you're interested in a full outdoor room with screens, heating, or lighting, those can all be incorporated. Electrical work on the deck requires a separate electrical permit and must be done by a licensed electrician.
Budgeting Realistically for a Kamloops Deck
Deck costs in Kamloops vary widely based on size, materials, and complexity, but some general ranges to work from:
- A basic pressure-treated deck (200–300 sq ft, no cover) typically runs in the $15,000–$25,000 range with professional labour, permits, and footings included.
- A composite-decked project of similar size will generally add $4,000–$8,000 to material costs.
- Adding a pergola or covered roof structure adds $10,000–$20,000+ depending on size and finishing.
- Hot tub decks require reinforced framing and often a dedicated electrical circuit — budget additional for structural and electrical work.
These are rough ranges. The best way to get an accurate number is to have a contractor look at your specific site, understand your goals, and put together a proper estimate.
Timing: When to Start Planning
For a deck you want to use this summer, now is the time to get the process started. Permit processing takes a few weeks, material lead times can vary (especially for composite decking, which sometimes has longer lead times during peak season), and scheduling with a reputable contractor fills up quickly in spring.
