    Basement Wall Restoration in Chatham, ON


    Problem: This home's basement seeped water in and did not have an efficient sump pump. There was carpet directly on the concrete slab.

    Solution: We installed a perimeter footing drain, a sump pump system with our battery backup, Bright Wall panels behind the laundry sink and Everlast Finished Wall System around the bathroom. Thermal Dry tiles were put down to keep the floor warmer and dry!

    Wet Basement Cold Storage Area, St. Thomas ON


    Problem: An unfinished cold storage area is a great place to store items to keep cool, such as canned food, even in the warm summer months. Although closed off from the rest of the house, if there’s water penetrating any area, it creates a damp, humid and unhealthy environment which affects the entire home in what is known as “The Stack Effect”.    

    Solution:  We installed a French drain system on the problem walls in the cold storage area, added a powerful sump pump with a battery backup for improved drainage and reliability and finished it off with our BrightWall® rigid basement wall system. Now this cold storage area is dry, heathy and will look fantastic for years to come.

    Water Penetrating Through the Floor of a Basement Springfield, ON


    Problem: This home has an unfinished basement that is used to house the laundry and mechanical components of the home; such as the hot water tank, electrical and the heating system. There was considerable evidence that water was penetrating from some of the exterior walls as well as up through the floor of the basement; causing cracks, water to pool on the floor and damage to the systems of the home.  

    Solution: Our team installed a perimeter drain on the leaky walls as well as a trench drain in the problem areas of the floor. We then finished off with some concrete work. Now these homeowners enjoy a clean, dry and safe basement as well as peace of mind knowing that the basement and home’s systems won’t suffer from any further water damage.

    What a transformation!

    A Healthy and Dry Basement in London, ON


    Problem:  This older home showed evidence of water penetrating an unfinished basement. The problem has likely been occurring for years. The conditions in a wet basement or crawl space affects an entire home.

    To understand this, let’s first look at how air circulates in a home.

    -         If there is water penetration in your basement or crawlspace, it increases the humidity level in your home.

    -         The lower areas of your home are cooler, and when this humid air warms (when it comes in contact with your heating system and floors, for example).

    -         This air rises throughout your home and escapes through the roof.

    -         More air is drawn in from the outside and up from the lower levels as air vents into the upper levels.

    This airflow in your home is known as the ‘stack effect’.

    The continual high moisture level in your home due to your wet basement or crawlspace is the ideal breeding ground for mould and allergens (such as dust mites). We know from the stack effect that this problematic air is circulating throughout your home.

    This moist air not only affects your family’s health; it also affects the structural integrity of your home, energy costs, resale value and the overall enjoyment of your home.

    Solution: Our products work together to give this homeowner a permanently dry basement:

    -         Perimeter drain – to direct water into the newly installed and superior;

    -         Triple Safe Sump Pump

    -         Moisture levels are kept in check with the extremely efficient, quiet and hassle-free Sani-Dry Sedona Dehumidifier

    -         The inorganic BrightWall Panels not only look great, but they are made of mould and mildew resistant, organic-free material

    Now these homeowners are enjoying a healthier home and a clean & dry basement!
