  • Crawl Space CleanSpace® Encapsulation System Installed for Moisture Control in Newcastle, ON
    Crawl Space CleanSpace® Encapsulation System Installed for Moisture Control in Newcastle, ON

    Crawl spaces are known to be dark, muggy, and often places we homeowners wouldn’t choose to go to unless completely necessary. However, many homeowners don’t understand how essential a crawl space is to the rest of the home. Your crawl space is a buffer between your home and the wet earth below. Unfortunately, as your crawl space works to protect your home, it can also collect too much humidity from water collection.


    Newcastle, ON, homeowners were experiencing a muggy stench lingering around. System Design Specialist Mark Dougherty recommended our CleanSpace® solution. Installed by Foreman Dave Jackson, he was able to encapsulate the area that would provide numerous benefits for the space. After they were done, the homeowners could not believe how immaculate and bright their crawl space looked! Not to mention the immediate improvement of air quality throughout the whole household.

Reasons to install a CleanSpace® vapor barrier in your crawl space

  • Prevent leaks through crawl space walls or floors

  • Create usable storage space in the home
  • Improve energy efficiency and reduce heating and cooling costs
  • Durable material with 25-year warranty

Steps to Installing A Crawl Space Vapor Barrier

  1. Install Airtight Doors & Vent Covers: Sealing your crawl space doors and vents will stop the cycle of cold air, humidity, and moisture entering from the outside. However, water can still enter your crawl space in many ways.
  2. Remove Any Standing Water Sources: The next step is to eliminate any sources of flooding in your crawl space by installing a crawl space drain and sump pump system. This eliminates flooding water from your crawl space, but moisture can still enter directly through the concrete and floor in the form of water vapor.
  3. Repair The Structure: If your crawl space is sagging or damaged by prolonged mold and rot, the next step is to install crawl space support jacks to help restore your structure. This will help your floors stay even and stop any structural sagging upstairs.
  4. Encapsulate & Insulate The Crawl Space: To stop moisture from passing through your floors and porous concrete walls, a crawl space liner should be installed. A durable liner will allow for servicemen to use the space without damage while transforming your crawl space into usable storage space. This is also the best time to install crawl space insulation on your walls or floors.
  5. Install A Dehumidifier: Installing an energy-efficient, self-draining crawl space dehumidifier will keep your space dry. Our crawl space dehumidifier system includes a filter that removes particles from the air as small as 2 microns. This ensures that your crawl space is protected from mold, dust mites, and mildew damage -- permanently!
