Signs that you Need Basement Waterproofing

When to Seek Basement Waterproofing in North York?

When it comes to basement waterproofing in North York, certain signs indicate it may be time to seek professional assistance.


If you see water seepage in the basement, wet spots on walls or floors, these signs signal that waterproofing is needed. Wet basement problems could be caused by issues such as cracks in the foundation walls, clogged gutters and downspouts, or poor exterior drainage, as well as foundation cracks or hydrostatic pressure.


Another sign is the growth of mold or mildew on walls, floors, or other surfaces. Moisture buildup creates an optimal environment for these harmful substances to thrive. Additionally, if there is a noticeable musty smell in your basement that doesn't go away even with good ventilation, it could suggest water infiltration that has lead mold.


To address these and other basement leak repairs effectively and prevent further damage to your property's foundation, reach out to professional basement waterproofers. We can help diagnose and repair the wet, damp, or leaky basement problems, ensuring your basement is free from leaks.

  • How long does basement underpinning take?
    The duration of a basement underpinning project can vary depending on various factors, including the size of the basement, the complexity of the existing foundation, and the specific underpinning technique used. Typically, basement underpinning projects can take several weeks to a few months to complete. The process involves a series of steps, including excavation, installation of temporary supports, underpinning the foundation, pouring new concrete footings, and allowing sufficient time for the concrete to cure. The timeline may also be influenced by factors such as weather conditions and any unforeseen challenges encountered during the construction process. It's important to consult with a professional contractor or structural engineer who can assess your specific situation and provide a more accurate estimate of the timeframe required for your basement underpinning project.

  • Common Foundation Problems?
    There is a number of foundation problems that may occur for different reasons. If you notice the or other foundation problems, make sure to talk to an expert as soon as possible as foundation problems tend to get worse over time. Here is a couple of foundation problems that we often see: Cracks in the foundation - cracks can occur due to settling, shifting soil, or poor construction. They can range from minor hairline cracks to larger, more serious cracks that affect the structural integrity of the foundation. Uneven or sinking foundation - may be caused by soil movement or inadequate soil compaction during construction and other problems. It can lead to uneven floors, gaps between walls and floors, or doors and windows that stick. Foundation heaving - heaving may be caused by the soil beneath the foundation expanding, which causes the foundation to rise. This can be caused by excessive moisture, frost, or poor drainage around the foundation. Basement leaks - water seepage or leaks in the basement can be a sign of foundation problems. They can occur due to cracks in the foundation, poor waterproofing, or improper drainage around the foundation. Bowing or leaning walls - when the foundation walls start to bow or lean inward, it is often a result of hydrostatic pressure from water-saturated soil pushing against the foundation. This can lead to structural instability and should be addressed promptly. Settling or sinking foundation - if the foundation settles or sinks unevenly, it can cause cracks in the walls, uneven floors, and misaligned doors and windows. This can be caused by soil consolidation, poor soil compaction, or inadequate foundation design. Foundation deterioration - over time, foundations can deteriorate due to age, exposure to moisture, or poor construction materials. This can lead to weakened foundation walls, crumbling concrete, or loss of structural integrity. The list goes on. Remember, these and other foundation issue should never be ignored. If you see any signs of foundation problems, talk to an expert as soon as possible!
