Retrofit Vapor Barriers in Historic Quebec Homes: The Hidden Upgrade That Protects and Preserves
Historic homes across Quebec are full of character, exposed stone walls, wooden beams, and timeless charm. But behind those beautiful features often lie some very real moisture problems. The good news? You don’t have to sacrifice your home’s heritage to protect it. A retrofit vapor barrier system, installed with CleanSpace® drainage matting, offers the perfect solution.
Why Older Homes Struggle with Moisture
Most older Quebec homes were built before modern moisture management techniques existed. If your home has a crawl space or basement with stone foundations, exposed earth, or poor drainage, you may already notice signs like:
- Persistent humidity and musty odours
- Mold or mildew on wood framing
- Crumbling mortar or wood rot
- Drafty floors and high energy bills
- Insects or rodents sneaking in
The underlying cause? Moisture and groundwater infiltration.
The Power of a Vapor Barrier + Drainage Matting
To protect your home from the ground up, we use a two-part system: CleanSpace® drainage matting and a CleanSpace® vapor barrier.
- The drainage matting is installed directly over the soil or rough surface. It’s a dimpled layer that helps channel groundwater and moisture toward a drainage system or sump, preventing water from pooling under the vapor barrier.
- The vapor barrier is then installed on top, sealing the floor and walls with a thick, mold-resistant liner.
Together, they work to:
- Block humidity and moisture
- Improve air quality
- Prevent structural damage
- Support long-term preservation of your home
- Increase energy efficiency and comfort
