Crawl Space Encapsulation Ottawa – Call (613) 746-7300
Crawlspace encapsulation refers to the process of sealing off a crawlspace beneath a home or building. Encapsulation typically involves covering the crawlspace floor with a waterproof barrier, installing vents or air handlers to control humidity, and insulating walls to reduce heat loss. The main purpose of crawlspace encapsulation is to create a more stable and energy-efficient home or building.

Crawl Space Encapsulation in Ottawa – Here are the key benefits:
- Improved energy efficiency: A properly encapsulated crawlspace can help reduce heat loss and gain, which can lower energy bills and improve overall energy efficiency.
- Enhanced indoor air quality: Crawlspace encapsulation can prevent moisture buildup, which can reduce the growth of mold and other harmful microorganisms. This can improve indoor air quality and reduce the risk of respiratory problems.
- Increased home comfort: By reducing humidity and preventing drafts, encapsulation can create a more comfortable indoor environment.
- Protection against pests: A sealed crawlspace can help prevent pests like rodents, insects, and snakes from entering the home.


Crawl space issues?
Let’s explore. A dirt crawl space floor can lead to moisture and mold problems in your home. The stack effect, where air from the crawl space rises into living areas, makes this worse. Even if the surface seems dry, moist earth lurks a few inches down, constantly releasing moisture.
The solution? Seal the crawl space from outside air and ground moisture. A thin plastic liner isn’t enough; you need to cover gaps, leaks, and vents too. Moisture causes mold growth, musty odors, structural damage, and high energy costs. To avoid these requires sealing the crawl space and removing moisture from the ground and air using a 20-mil 7-ply sandwich of high and low-density polyethylene with polyester-cord reinforcement on the dirt floor that extends and fastens to the walls. This lining is treated with an antimicrobial finish to protect against mold and mildew growth. In some cases, a high-performance dehumidifier air filtration unit is added to keep humidity levels below 50%. Proper ventilation is a key component. Studies have shown that crawl spaces need air and humidity conditioning, just like the rest of the house.
