What's included
Our privacy screen and wind wall service covers the full panel assembly: pressure-treated SPF framing, through-bolted 4×4 or 6×6 posts anchored to the deck structure (or to concrete piers if freestanding), 1×4 or 1×6 slat infill in your choice of Western Red Cedar, Alberta larch, or composite (Trex Transcend / TimberTech), a continuous top cap rail, and on-site stain or oil finish. Every screen is designed for the wind load it actually sees in the Bow Valley - we calculate the lateral load against the post anchoring and adjust slat spacing to bleed wind pressure rather than catching it like a sail.
Common configurations: 6-foot privacy screen along a property line, 4-foot wind wall on the prevailing-wind side of a deck, an L-shaped screen wrapping a hot tub corner, or a louvered upper section over a solid lower panel for the privacy-plus-airflow combination. Optional integrations: planter boxes built into the base, LED accent lighting in the cap rail, climbing-vine trellis attached to the back.
Who this is for
- Townhouse and infill homeowners in Spring Creek, Three Sisters, or Old Canmore where deck-to-neighbour sightlines are 15 feet or less
- Hot tub owners wanting a privacy enclosure that doesn't trigger a full sunroom permit
- West- or south-facing decks that get pummeled by prevailing Chinooks in spring and fall
- Bow Valley homes near road or trail traffic where street-side sightlines need breaking up
- Outdoor kitchens or fire-table areas needing a wind break to keep flames and smoke controlled
- Rental properties (Airbnb / VRBO) where guest privacy from neighbouring units affects bookings
Our process
- Sightline and wind assessment. We walk the deck with you, identify the specific sightlines and wind directions to block, and measure for screen height and length.
- Permit check. Confirm whether the proposed screen is under the Town of Canmore 1.8 m exemption or requires a development permit. We handle the application if required.
- Material and slat selection. Cedar vs. larch vs. composite samples, slat spacing options (typically 1/4 inch to 1 inch gap), top cap profile.
- Post anchoring design. Through-bolted Simpson DTT2Z holdowns at deck connections or helical piles for freestanding. Engineering check for screens over 6 feet or unusual spans.
- Build and install. Posts plumb and braced, frame assembled, slats cut and fastened with hidden or face-screw connections, top cap installed continuous.
- Stain and finish. Two coats of penetrating oil on cedar/larch, factory-finish on composite. We brush every gap so slat edges are sealed.
Material & method comparison
| Material | Privacy at 6 ft | Wind load handling | Maintenance |
|---|---|---|---|
| Cedar 1×4 (1/2" gap) | ~85% block | Excellent (bleeds wind) | Oil every 2-3 yrs |
| Cedar 1×6 (1/4" gap) | ~95% block | Good (higher wind load) | Oil every 2-3 yrs |
| Alberta larch 1×4 | ~85% block | Excellent | Oil every 2-3 yrs |
| Composite slat | ~90% block | Excellent | None - wipe down |
| Solid + louvered hybrid | ~100% lower / 70% upper | Mixed (engineered) | Per material |
Pricing factors
- Linear footage - straight runs are most cost-effective; corners and L-configurations add post and labour cost roughly 12-18%.
- Height - 4 ft wind wall runs roughly 65% of a 6 ft privacy screen; 8 ft engineered screens cost roughly 150% per linear foot of a 6 ft panel.
- Material - cedar baseline; larch +15-20%; composite +50-60%; solid + louvered hybrid panels +20-25%.
- Foundation - attached to existing deck is most economical; freestanding screen on helical piles adds $450-650 per pile.
- Finish - included on cedar and larch; custom stain colours or two-tone finishes add $4-8 per linear foot.
Bow Valley local context
The Bow Valley's Chinook winds drive every privacy screen engineering decision we make. Environment Canada records show Cougar Creek and the Three Sisters area regularly hit 100 km/h gusts and have documented over 130 km/h in spring 2022. A 6-foot solid screen catches roughly 0.7 kPa of wind pressure at that gust speed - which is why we calculate the post anchoring against that load, not just code minimums. Slat spacing isn't just aesthetic; a 1/2 inch gap between 1×4 boards reduces wind catchment by roughly 25% compared to a solid panel of the same area, which significantly cuts the lateral load the posts have to resist.
For freestanding screens we use helical piles to 1.6 m (below Canmore's 1.2 m frost line); for attached screens we tie into the deck rim joist with Simpson DTT2Z holdowns rated for 1,825 lb tension.
Permit note: Town of Canmore allows fences and detached privacy screens up to 1.8 m without a permit in rear and side yards (front yard limit is typically 1.0 m). Anything taller, attached to a principal building, or positioned within a setback requires a development permit. In Banff, Parks Canada material guidelines apply - cedar and larch slats are typically approved; brightly painted finishes are not.
Why choose Canmore Deck Builders
Wind-engineered, not guessed
Every privacy screen we build is sized for documented Bow Valley wind loads - 100 km/h sustained, 130 km/h gust. We use through-bolted Simpson DTT2Z holdowns on attached screens and helical piles to 1.6 m on freestanding panels. We haven't had a screen fail in 10 years of Bow Valley installs.

We don't default to the same 1/4 inch gap on every job. On exposed Chinook-side screens we open the gap to 1/2 or 5/8 inch to bleed wind pressure; on neighbour-facing privacy screens we tighten to 1/4 inch for maximum visual block. Each panel is calculated for the load it actually sees.
5 standard slat spacings · site-tunedNo-permit pathway where possible
We know the Town of Canmore exemption rules cold. Most of our screens land at exactly 1.8 m and stay out of front-yard setbacks, which keeps the project permit-free and shortens timelines by 14+ days. When a permit is required we handle the application and have never had one denied.
