  • Diagnosis

    Multiple factors can cause water leakage in a basement. One of those causes is rainwater gathering near the foundation and seeping through into the basement foundation and floors.

    Other causes are:

    • Cracks on the basement floors, doors, and windows allowing underground water through
    • Plumbing issues causing the pipes to leak.
    • Dysfunctional sump pumps that are not draining water away from the basement.
    • Poor ventilation in the basement, resulting in excess moisture that condenses into water.

    Each of these problems needs different solutions to be permanently fixed. You need experts to identify those causes correctly; otherwise, your remedial measures could be fruitless. Only professionals with years of experience and extensive knowledge and equipment will be able to determine the causes of the leaks accurately. They are also in a better position to deliver befitting solutions that aren’t trial and error.

  • Preventing Further Damage

    Regardless of the cause, leaks have the potential to cause costly damages if not tackled soon. The best approach is to prevent the damage from happening. If it does, your best solution will be to prevent it from spreading. Prevention will not only save you a lot of money; it will also keep you safe by maintaining the integrity of the property. Proficient waterproofing service providers can prevent damages from happening. Call a team for regular inspections, and they will identify potential problems and solve them before they occur.

Since such issues could damage the foundation and structure of the house, you will rest easy knowing your home is well-protected. You won’t worry about other potential problems like flooding and the financial repercussions they can have on you.

How to detect hidden basement leaks in 3 simple steps


    Leaks from the walls are usually some of the hardest to identify unless you pay close attention. However, sometimes the signs will be easy to spot, especially when you have bright colours on the walls. Some of the signs we look for are:

    Chalky substances: The substance, known as efflorescence, is sometimes white in colour. It forms when water reaches the inner walls and dries out, leaving the crystalline substance.

    Discoloration: We also look for staining on the walls as it can also indicate signs of water presence. The stains could be small spots or large ones, depending on the pattern of the damage. The stains are usually caused by acidic water from outside the house. We take care of the problem as quickly as possible to ensure no further damage is done.

    You could also do a simple experiment using foil paper. Seal in aluminum foil and place it on the wall for 48 hours. If you notice moisture on the foil, you’ll know there is moisture on the walls. Contact us the moment you observe this, and we will give you a permanent solution.


    Increasing moisture could be the first sign that your basement isn’t in optimal condition. In most cases, your basement may be damp and cold if it doesn’t have good ventilation and insulation systems. If you have invested in quality systems that have also been installed correctly, there shouldn’t be extra moisture. If there is, the water could be coming from another place, like the foundation or the cracks on the floor allowing water from the ground to reach inside the basement.

    We will start by inspecting the cove area. This area, where the wall and the floor converge, is susceptible to cracking and allowing water in. Our professionals will look for cracks.


    Mould can cause a lot of health issues that range from eye and skin irritation to respiratory tract infections. Different types of moulds produce various types of pores that could have different repercussions. The presence of mould can be identified through a musky smell in the room or dark spots on the walls. We will inspect your basement to determine the type of mould growing there. We will then remove them and ensure they don’t recur.

    It’s not advisable to paint over mould because it will keep spreading as it grows under the paint. Fungi can still be dangerous even if you don’t see them.
