Outdoor construction in Montreal lives or dies by what you don't see. The footings, the drainage, the substrate compaction, the joist hangers, the screw piles versus sonotubes — those are the decisions that determine whether your $80,000 deck and patio still look new in year ten or look tired in year three. Revohouse builds outdoor space to the same structural standards as the interior, which is the only way to survive a Montreal freeze-thaw cycle over a decade.
What we handle
- Site assessment: grading, drainage, frost-line depth, setback compliance
- Permit applications for decks above 60 cm, pergolas, and covered structures
- Excavation, base preparation, and compaction (vibratory plate-compacted in lifts)
- Footings: bell-bottom sonotubes, helical screw piles, slab-on-grade where appropriate
- Decks: pressure-treated framing with composite, ipé, or thermally-modified ash top
- Patios: concrete pavers, large-format porcelain on adjustable pedestals, flagstone, poured concrete
- Retaining walls: segmental block, poured concrete, natural stone — engineered above 1.2 m
- Pergolas, gazebos, and covered outdoor structures
- Outdoor kitchens: gas line runs, electrical, drainage, weather-rated cabinetry
- Outdoor lighting (low-voltage and 120 V), GFCI circuits, lighting controls
- Drainage management: French drains, downspout extensions, dry wells
What it costs
Most outdoor-construction projects in Montreal and the West Island land between $25,000 and $180,000. A 300 sq ft paver patio with planting and lighting runs $25K–$45K. A 500–700 sq ft deck with a pergola and built-in seating runs $60K–$110K. A multi-element project — deck, paver patio, outdoor kitchen, retaining wall, irrigation, lighting — reaches $120K–$180K. Stone selection and structural complexity (retaining walls, screw-pile foundations on slopes) move the number fastest.
How the schedule works
Outdoor construction is seasonal. Design, permits, and ordering run through winter; construction runs April–November. A typical project from signing to completion is 12–24 weeks, of which 6–12 weeks are on-site once the ground is workable. Pour-dependent work (concrete patios, footings) is weather-windowed; we hold pours when overnight lows drop below 5°C.

Warranty and seasonal returns
Hard-landscaping installations carry our one-year workmanship warranty plus manufacturer warranties on pavers, composite decking, and outdoor kitchen components. We return to site the following spring for a free walk-through — settling check on patios, joint sand top-up where needed, fastener inspection on decks, and a review of any drainage adjustments after the first winter. Plant material and softscape installs are coordinated through our landscape sub-trade with their own seasonal guarantee terms, spelled out in the contract.
