Signs that Waterproofing is Needed

Why Get Basement Waterproofing Services Newmarket?

Several signs indicate the need for basement waterproofing services in Newmarket. First, we recommend getting your basement leakproof - before you notice first signs of a wet, damp, or leaky basement. Waterproofing works best as a preventative measure, as opposed to repair.


However, this is not always possible. In this case, watching for the presence of water stains or discoloration on the basement walls or floors is one such sign, as it suggests water seepage.


In addition, the presence of mold or mildew in the basement is a clear indication of excess moisture, which can be a result of poor waterproofing. Unpleasant odors or a damp, musty smell in the basement can also signal the need for waterproofing services.


Cracks in the foundation or walls, as well as peeling paint or wallpaper, are further signs that water is entering the basement.


Working with professional waterproofing contractors, you can address these and other wet basement problems. By getting professional services, homeowners in Newmarket can protect their property from water damage, increase the longevity of their basements, and create a healthier living environment.

  • 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.

    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.
