Challenge: These London homeowners thought they could seal the issue on their own until they recently noticed they were not properly filled and have been letting moisture in behind the drywall.

Solution: We installed our interior waterproofing system with our in-floor drain, moving any seeping water in the sump pump. We provided these homeowners with a peace of mind by installing our TripleSafe sump pump systems, with three levels of protection, these homeowners are ready for the heaviest rainfall. Finally, our team installed our full height, ThermalDry wall barrier to help reflect heat back into their dry space.

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!

We're looking for someone to take a look at a few things in our basement and offer your advice/quotations. Half of our basement is quite old and we plan to be here for a long time so we'd like to address any issues with long-lasting solutions. 1-We have two dirt floor crawl spaces, one part of original construction in the 40s and one recently constructed in ~2015. Both have been "encapsulated" poorly by previous owner/flipper. The humidity on the new side is fine and has two forced air supplies and a poured concrete foundation. The humidity in the crawl space on the original side is very high and has some mold growth and that smell. There is no outdoor vent and we've added a forced air supply, it has helped but not resolved the issue. Winter has been totally fine with humidity under 50%, it is just an issue during the summer. We'd like a quote for a full encapsulation of at least the original side, and any thoughts you may have on the situation. 2-Cracks in basement floor, no water coming through but while you are here if you could let us know your opinion on whether they need to be addressed/filled/etc. 3-Take a look at the foundation walls part of the original construction to see if there are any apparent issues, we've noticed a couple things like uneven walls/floors in the house on the main floor above the original crawl space...not sure if these could be any indicators 4-discuss whether a sump pump system and perimeter drainage would be warranted/required in our situation - we currently have no drain in the basement and our sanitary connection is a few feet above the basement floor 5-ballpark costs for basement floor lowering, could lowering of crawl space area and pouring a slab be considered? I dont think we have any drawings of the original foundation depth Apologies for the length and I appreciate your time in reading this! Thanks, Phil

I have a leak in the wall of my crawl space. There has been a previous fix to this crack in the wall before but it appears the fix has now failed. Looks like the filler placed in the crack has a gap in places where the water might be coming in.
