Crawl Space Encapsulation
In Toronto
What is Basement Crawl Space Encapsulation?
The crawl space is an area with a limited ceiling height, located in the basements of homes and businesses. In many cases, crawl spaces do not have floors and are open to the soil below the building. As a result, moisture can accumulate in the crawl space, leading to mould and mildew growth, which can damage the floors and furniture on the ground floor, as well as undermine air quality.
The encapsulation process involves the application of a polyethylene barrier to the crawl space floors, walls, and sometimes ceilings, in the crawl space. After sealing, a dehumidifier is installed to circulate air and help control humidity. This can add value to your house while making it a safer and healthier environment for you and your family.
Benefits of Crawl Space Encapsulation
Protecting your crawl space from water can benefit your property with better air quality, increased value and more.
Encapsulation helps prevent moisture from entering your crawl space, reducing the risk of mould, mildew, and rot. It acts as a vapor barrier, preventing groundwater from rising into the living areas of the building.
By preventing moisture infiltration, encapsulation helps to reduce mould growth and the spread of allergens. This fresh air benefits the health of the occupants, especially those with respiratory conditions or allergies.
An encapsulated crawl space with proper insulation can contribute to your home’s energy efficiency by reducing air leakage and heat loss during the cold months. It creates a thermal barrier that prevents outside air infiltration and reduces the load on your HVAC system.
By controlling humidity levels, crawl space sealing helps prevent wood rot, decay, and damage to the foundation or concrete floor. This can lead to long-term cost savings by avoiding expensive repairs.
A sealed crawl space can act as a barrier against pests such as termites, rodents, and insects. By eliminating entry points and reducing excessive moisture, encapsulation discourages these pests from infesting the basement and potentially spreading into the living areas of the building.
By controlling humidity and eliminating moisture, basement crawl space encapsulation can help extend the lifespan of HVAC systems. It leads to efficient operation and lower maintenance and replacement costs by minimizing the risk of corrosion and damage to ductwork and equipment
Potential buyers are often attracted to homes with a well-maintained and encapsulated crawl space. A properly sealed basement can contribute to a higher value for your home should you choose to sell.
What's Included in Crawl Space Encapsulation in Toronto?
Crawl space sealing or encapsulation often includes the following services:
- Seal Crawl Space Vents – Blocks outdoor air and pests while reducing moisture entry.
- Dehumidifier Installation – Helps reduce moisture and mould growth to improve air quality.
- Vapor Barrier Installation – Prevents moisture seepage to keep your crawl space and home dry.
In some cases, Aquamaster’s more traditional waterproofing and leaky basement repair services can also apply to these projects, including:
- Sump Pump Installation – Pits accumulate water that is then pumped out of and away from your home to prevent damage.
- Drainage system installation – Including weeping tiles and French drains, these systems channel water away from your foundation to keep it from collecting under your home.
- Foundation Crack Repair – Similar to basements, crawl spaces can also have cracks in the foundation walls. These are important to repair before sealing the area.

The Crawl Space Encapsulation Process
- Assessment – One of our licensed contractors will begin by inspecting the crawl space to evaluate its condition and identify any existing issues such as humidity problems, poor drainage, mould growth, or structural damage.
- Moisture Control – It’s important to address heightened moisture levels before sealing the basement. This may involve fixing leaks, improving drainage, and addressing standing water or excessive humidity.
- Cleaning and Preparation – The space is thoroughly cleaned to remove debris, dirt, and any existing mould or mildew. This step may include removing insulation, if necessary.
- Air Sealing – Gaps, cracks, and openings in the crawl space walls and floor are sealed to prevent cold air leakage and water infiltration. This helps create an airtight barrier.
- Vapor Barrier Installation – A vapor barrier, typically made of heavy-duty polyethylene sheeting, is installed on the floor and up the walls. The barrier is securely fastened and sealed to prevent water from entering the crawl space from the ground.
- Crawl Space Insulation – Depending on the climate and building requirements, insulation may be installed on the basement walls or ceiling to provide additional thermal protection. This helps to prevent heat loss in winter and heat gain in summer.
- Dehumidification & Ventilation – In some cases, a dehumidifier or ventilation system may be installed to maintain optimal humidity levels in the encapsulated crawl space. This helps to further control moisture and prevent the growth of mold or mildew.
- Encapsulation Access Points – Access points such as doors or hatches are sealed and insulated to maintain the integrity of the encapsulated space while still allowing for future inspections or maintenance needs.
- Maintenance & Monitoring – Regular maintenance and monitoring are essential to ensure the effectiveness of the encapsulation. This may involve checking for signs of moisture, inspecting the barrier, and maintaining proper ventilation and dehumidification.
