    Crawl Space Leaves Cottage Smelling Musty in Fenelon Falls, Ontario

     When you arrive at a cottage, the first thing you expect is the smell of nature as you get out of the car, and maybe a small fire burning in a wood stove. What you don’t expect is a musty smell coming from a crawl space, spreading throughout the entire cottage. 

    A customer in Fenelon Falls, Ontario, was dealing with a musty smelling basement. Water was entering the space, and the smell was starting to render the cottage unuseable. The cottage owner reached out to Clarke Basement Systems, and System Design Specialist Ryan Hanlon designed a full waterproofing system for the crawl space. The system included a complete encapsulation with CleanSpace® Vapour Barrier, and R20 Wall Membrane to insulate the space, installed by Foreman Lucio Flores

    The customer is thrilled that her basement is now waterproofed. Not only did we eliminate the smell, but we also blocked a hole in the foundation that raccoons were using as an entryway to the crawl space. Some unhappy raccoons but a very happy customer!

  • A Complete Transformation by a CrawlSpace Encapsulation in Orillia, ON
    A Complete Transformation by a CrawlSpace Encapsulation in Orillia, ON

    Homeowners in Orillia, ON, were concerned about their dirty and musty crawlspace. The crawlspace wasn’t insulated well enough, causing a lot of heat to be lost during the winter. It also had an awful musty smell that was extremely uninviting!

    The homeowner was anxious about the cost that would incur if they did nothing to fix the crawlspace and even refused to spend time away from their home during winter because they feared the pipes would freeze from the heat loss. Luckily, they contacted Clarke Basement Systems for a free estimate with System Design Specialist, Rob Malcomson.

    Once he inspected the home, he knew that the best solution was to encapsulate and insulate the crawlspace completely. Our team would need to remove and dispose of all debris and old insulation, install CleanSpace® liner and CleanSpace® Drainage Matting to existing walls and floors and install ThermalDry® insulation on all exterior walls to joists.

    Once the work was complete, the homeowner was ecstatic and relieved knowing that their crawl space was cleaned out, encapsulated and insulated. The homeowner would no longer have to worry about heat loss, rodents, or the health of the home.

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

  • Prevent cold air, humid air, and excess moisture from entering the 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!
