Winter Construction in Alberta: What's Possible?
Alberta's long winters don't mean construction stops. Many projects continue through -20°C and beyond. Here's what works in winter, what doesn't, and how we handle cold-weather construction.
What Works Well in Winter
Interior Renovations
Winter is actually ideal for interior work:
Kitchens and bathrooms: All work happens inside
Basement development: Below-grade space is naturally temperature-stable
Flooring and painting: Climate-controlled environment
Drywall and finishing: No weather concerns
Benefits of winter interior renovation:
Contractors have more availability
Possible off-season pricing
Project complete before spring/summer entertaining
Foundation Work (With Precautions)
Concrete can be poured in winter with proper techniques:
Heated forms and blankets
Concrete with cold-weather admixtures
Extended curing time in enclosures
Temperature monitoring throughout cure
Temperature limits:
Generally feasible above -15°C ambient
Challenging below -20°C
Not recommended below -25°C (frost protection too expensive)
Framing and Structural Work
Wood framing proceeds year-round:
Lumber handles cold well
Interior quickly enclosed and heated
Roof dried in before finishing
Considerations:
Snow management on site
Working conditions for crew
Some materials (adhesives) need warmth
What's Challenging in Winter
Roofing
Shingle installation has temperature limits:
Asphalt shingles become brittle below ~5°C
Adhesive strips don't seal properly in cold
Ice and snow create safety hazards
Best approach: Complete roofing in fall, or install temporary weather protection until spring.
Exterior Finishes
Cladding and siding installation is difficult:
Some products crack in cold
Sealants don't cure properly
Working conditions are challenging
Quality suffers
James Hardie siding: Manufacturer recommends above 4°C
Vinyl siding: Can be installed but becomes brittle
Stucco/EIFS: Requires heated enclosures—expensive
Excavation and Earthwork
Frozen ground creates challenges:
Harder to dig (more expensive)
Frost heaving concerns
Backfill limitations
Landscaping impossible
Best approach: Complete major excavation before freeze-up.
Painting (Exterior)
Exterior painting essentially stops in fall:
Most paints require 10°C+ for proper cure
Low humidity causes application issues
Risk of failure is high
How We Handle Winter Projects
Site Management
Snow removal before starting each day
Heated enclosed work areas where needed
Proper material storage (some materials can't freeze)
Additional lighting for short winter days
Crew Considerations
Shorter work days in extreme cold
Warm-up breaks (safety requirement)
Appropriate safety gear
Modified scheduling for weather
Quality Control
Extended cure times for concrete
Temperature monitoring for critical materials
Additional inspections during critical phases
Protection of completed work from weather
Planning for Winter Projects
Start Early
If you want a winter project:
1.
Contact us in fall: Planning takes time
2.
Finalize design before freeze-up: Permits need lead time
3.
Order materials early: Winter can affect supply chains
4.
Be flexible: Weather will affect some activities
Budget Considerations
Winter construction may cost more or less:
Potential cost increases:
Temporary heating
Weather protection measures
Extended schedules due to cold days
Concrete heating requirements
Potential savings:
Contractor availability (less demand)
Possible off-season discounts
Material sales
Net effect: Usually close to similar, sometimes 5-10% difference either direction.
Timeline Impacts
Be realistic about winter timelines:
Extreme cold days may stop outdoor work
Short days limit productivity
Weather-dependent activities may pause
Build in buffer time
Real-World Examples
Basement Development (Great for Winter)
We've completed many basement projects in January-February:
Excavation: Already below grade, no issue
Concrete: Existing walls, just finishing
Framing/drywall: All interior
Mechanical: Interior work
Result: On-time, on-budget, happy clients
Custom Home (Mixed Timing)
One recent acreage build timeline:
Fall: Foundation, framing started
Winter: Framing completed, roof dried in, all interior rough-ins
Spring: Exterior finishing, landscaping
Summer: Move-in
Key: Started foundation before freeze-up, enclosed quickly.
Addition (Strategic Planning)
A recent home addition:
Fall: Foundation and framing
November: Roof on, building enclosed
Winter: Interior finishing (heating in place)
Spring: Siding and exterior details
Summer: Deck and landscaping
Key: Roof on before snow, interior work continues through winter.
Questions to Ask About Winter Projects
Before Starting
What parts of this project are weather-dependent?
How will you handle extreme cold?
What's the realistic timeline considering winter?
Are there cost implications?
During the Project
What's the minimum temperature for today's work?
Is anything being deferred to warmer weather?
How are materials being protected?
Bottom Line
Winter construction in Alberta is common and manageable—when properly planned. The key is understanding what works in cold weather, what doesn't, and planning accordingly.
Interior renovations? Start anytime. New construction? Plan to get the exterior enclosed before the coldest months. Major exterior work? Schedule for warmer seasons.
