Winnipeg Decks & Structures
Outdoor structures anchored below the frost
Custom decks and pergolas, built on screw piles or footings that reach below Winnipeg’s frost line — so your outdoor room stays dead level while the ground heaves around it every winter.
What we build up
The rooms you add without a foundation
Structures are the built-up, above-grade parts of a yard — decks and pergolas that add usable living space, shade and a sense of a real outdoor room. They’re carpentry more than masonry, but in Winnipeg they live or die by the same thing everything else does: what’s holding them up underground.
Our frost line runs close to 1.8 metres, and our clay heaves hard every freeze-thaw. A structure whose supports don’t reach below that line will lift in winter, drop in spring, and slowly rack itself out of square. So every post we set is anchored on a screw pile or a proper footing that goes below the frost — the single reason a good deck stays dead level for decades.
BerryHill builds decks and pergolas in-house, from the piles up, and handles the City permit paperwork so you never have to learn what a grade beam is.

Deck Construction
Custom wood and composite decks — single-level to multi-tier walkouts — built on piles below the frost line, with the railings, stairs and built-ins that make it a room you actually live in.

Pergolas and shade structures that define a patio, cut the July sun and stretch the season — engineered for our snow load and anchored so they don’t shift with the ground.

A deck with a pergola over part of it is one of the best outdoor rooms you can add. We’ll walk your yard, talk materials and budget, and design the structure that fits.

The footings are the whole ballgame
A deck that’s still level in fifteen years and one doing a slow-motion funhouse impression differ in exactly one place — below grade, where you’ll never look.
- 01Anchored below the 1.8 m frost line. Screw piles or poured footings that reach past the frost so winter can’t grab and heave your posts.
- 02Screw piles or concrete — your call. Piles go in fast with less mess and shrug off heave; concrete costs less up front. We’ll tell you honestly which suits your yard.
- 03Built to code, permits handled. Proper spans, bracing and snow-load hardware — and we pull the City permit and pass the inspections for you.
- 04Materials matched to you. Pressure-treated, cedar or maintenance-free composite — chosen for how much upkeep you actually want.
The footings and the base are invisible the day the deck is finished — and they’re the entire reason it’s still standing straight when your kid graduates. We don’t cut them.
