Our Crawl Space Services in Ontario

  • Crawl Space Encapsulation: A crawl space vapor barrier is essential for preventing excess moisture from entering the space and causing mold growth.

  • Crawl Space Insulation: Insulating your entire crawl space helps eliminate drafts and will make your home more comfortable and energy efficient.

    Tight Crawl Space Project Windsor, ON

    Before
    After

    Problem: This tight and musty area under the home was starting to cause mould growth on the wood supports. Wood is everywhere inside a home and if it begins to rot due to high humidity and moisture, it can be a very costly repiar. We needed to get to work here right away!

    Solution: We cleaned out all the debris of this small space. Then we installed our Clean Space Encapsulation System (the white liner). Once that was installed, our crew came in and spray foam insulated the headers (above the foundation wall where a lot of air leaks get in). The space is now safe and healthy.

    Before
    After

    Problem: This home’s crawl space was damp and musty. Through what is known as The Stack Effect, this undesirable air made its way into the home, resulting in musty, damp and mouldy smells. Some of the fibreglass insulation on the exterior walls was wet and had lost its insulating properties.

    Solution: We improved the drainage in the space and encapsulated the dirt floor with our heavy duty CleanSpace crawl space vapour barrier. Our team also added mould and mildew proof SprayFoam Insulation on the exterior walls and also as a sealant on the vapour barrier.

    Fixing a Gravel Filled Crawl Space in Essex County, ON

    Before
    After

    Problem: Many homeowners believe that putting a layer of gravel in their crawl space will solve the water and moisture problems. This isn’t true and doesn’t work. 

    Gravel is porous and it does not stop water from moving or collecting.

    Fixing a crawl space with a gravel floor presents two challenges:

    1. It is difficult to dig trenches and create drains to properly direct the water out of the crawl space compared to dirt.

    2. To further keep the humidity level acceptable and encapsulate the space, a very heavy duty liner is required, as the liner will be more prone to rips and tears with the rough gravel below it.

    Solution:

    • Our experienced team members were able to create trenches and drains to effectively move the water into the crawl space sump pump.

    • Our CleanSpace®️ Liner is super heavy duty and durable enough to withstand the rocky floor encapsulated below.
