    Broken Sump Pump Stinks Up Crawl Space in Fenelon Falls, Ontario

    Who doesn’t love going to the cottage? From leaving work on a Friday afternoon to when you first walk through the door, we can’t wait to get away from it all and smell the fresh air. For a customer in Fenelon Falls, Ontario, fresh air wasn’t all she was smelling. A broken, old sump pump was causing quite a stench in her cottage crawl space. The odour was spreading throughout the whole cottage and had become the main talking point when guests came to visit.  System Design Specialist Ryan Hanlon created a full waterproofing system for the customer that included a SmartSump® Sump Pump and an UltraSump® Battery Backup. Foreman Lucio Flores and his crew installed the products, removing not just water from the crawl space, but the musty smell too. The customer is delighted that her cottage smells fresh once again. Her basement is waterproofed for many years to come, with a warranty too!

    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!

    Humidity Causes Crawl Space Mould at Cottage in Fenelon Falls, Ontario

    When you head up north to the cottage, the last thing you want to do when you get there is deal with a damp crawl space. The smell can be horrible, and the humidity can cause severe damage to the building. A customer in Fenelon Falls, Ontario, reached out to Clarke Basement Systems, looking for a solution for her wet crawl space. System Design Specialist Ryan Hanlon met with the customer and inspected her cottage. He designed a waterproofing system that included an Aprilaire® MoistureLoc Dehumidifier, which keeps the relative humidity below 55%. Foreman Lucio Flores installed the dehumidifier strategically in the crawl space, complimenting the rest of the waterproofing system. The customer is delighted that she no longer needs to worry about damage to her cottage caused by moisture and mould, and the first thing she notices when she steps inside isn’t a musty smell.
