What Is a Vapor Barrier?
A vapor barrier (or vapor retarder) is a layer of material designed to prevent moisture from passing through walls, floors, and ceilings. It’s especially important in areas prone to condensation or high humidity, like basements, crawl spaces, and slab-on-grade floors.
Proper vapor barrier installation helps protect insulation, reduce mold risk, and maintain long-term structural integrity.
Why Vapor Barriers Matter in Calgary
Calgary’s climate includes wide swings in humidity and temperature, especially in winter. This leads to condensation buildup on cold surfaces—causing mold, damp insulation, and even water damage over time.
Benefits of installing a vapor barrier:
- Protects insulation from moisture damage
- Reduces mold and mildew in basements and crawl spaces
- Prevents condensation on cold surfaces
- Extends the life of floors, walls, and foundation materials
- Improves indoor air quality and home comfort
- Essential for building code compliance in certain applications
From basements in Bowness to farm shops outside the city, vapor barriers are a must-have for moisture protection in Calgary buildings.
Our Vapor Barrier Installation Services
We offer professional-grade vapor barrier systems for multiple areas of your property.
Crawl Space & Basement Vapor Barriers
We install heavy-duty vapor barriers on dirt or concrete crawl space floors and basement walls to prevent ground moisture from seeping upward. This helps protect insulation, framing, and flooring from dampness and decay.
Floor Vapor Barriers
Planning to finish a basement or install new flooring? We install vapor barriers under slab and beneath flooring to stop water vapor from rising through the concrete and damaging your floor materials.
Wall Vapor Barrier Systems
When insulating new walls or replacing insulation, we install vapor barrier sheets to prevent condensation within wall cavities—essential for maintaining insulation R-values and avoiding mold growth.
Vapor Barrier + Insulation Packages
We combine vapor barriers with cellulose insulation to provide complete moisture and thermal protection—ideal for basements, garages, and energy-efficient new builds.
Common Places to Install a Vapor Barrier
- Basement floors and walls
- Crawl spaces
- Under concrete slabs
- Below laminate, vinyl, or hardwood flooring
- Inside wall cavities (especially exterior walls)

Frequently Asked Questions
What is a vapor barrier and do I need one?
A vapor barrier is a protective layer that prevents moisture from passing into insulation and structural areas. In Calgary, it’s essential in basements, crawl spaces, and other high-moisture zones.
How is a vapor barrier installed under flooring?
We place a moisture barrier directly over concrete or subfloor, sealing edges to prevent vapor migration. It’s common beneath vinyl, laminate, and hardwood floors.
What type of vapor barrier do you use?
We use heavy-duty polyethylene sheets rated for specific applications (floors, crawl spaces, walls) and seal all seams and edges for complete protection.
Do I need a vapor barrier if I already have insulation?
Yes—insulation without a vapor barrier can still absorb moisture, reducing its effectiveness. The two work best as a system for full moisture and energy control.
Is a vapor barrier required by code in Calgary?
In many applications—especially basements and exterior walls—yes. We ensure all our installations meet or exceed local building codes.
