    Basement waterproofing types and prices

    Exterior basement waterproofing cost

    Exterior basement waterproofing is done by excavating the building or house to the foundation wall’s full depth. Excavation is vital because it clears the foundation of any soil or debris. Next, the foundation is waterproofed from the outside by installing waterproof membranes. The membrane is then topped by a drainage panel that lets the water flow to an exterior drain at the base of the foundation.

    The price of exterior basement waterproofing in Toronto, Ontario may vary according to the depth of the trench, ease of access to the foundation, and extent of damage. The baseline price is $120 per linear foot.

    Interior basement waterproofing cost

    It is important to note that interior basement waterproofing is done from the inside of the house and involves the use of waterproofing materials such as a membrane, epoxy injections, sealants, or a drain connected to a sump pump to prevent any flooding in the basement. As a result, the interior waterproofing approach is generally the most cost-effective and works well in situations where it is not practical to access the exterior of the foundation to install waterproofing materials.

    The cost of interior basement waterproofing in Toronto, Ontario starts at $75 per linear foot and will vary depending on the materials and methods needed. The best interior waterproofing option is to use a waterproof membrane together with a drain and sump pump system that will move water out of the home entirely.

    Factors that determine the basement waterproofing cost

    Waterproofing method

    As mentioned, exterior waterproofing tends to be more expensive compared to interior waterproofing. However, cost should not be your sole deciding factor when it comes to choosing between interior or exterior waterproofing. If you are aiming for a long-term solution, it is better to go for exterior basement waterproofing. Sealants and waterproof paints may not work as well as extensive exterior waterproofing. Consider the benefits and practicality of each method before settling on which to use.

    Foundation depth

    The depth of your foundation will impact the overall cost of whichever waterproofing method you settle on. Deeper foundations require more labor and materials. Most foundations are somewhere between 5 and 8 feet deep.

    Fixing Cracks & Crack/Foundation Reinforcement

    Before the basement is waterproofed, we will have to determine if there are any leaks and what might be causing them. Some solutions, such as epoxy injections, are simpler and more budget-friendly. Foundation reinforcement, on the other hand, is a much more extensive process and the cost would reflect that.

    Waterproofing materials

    The materials to be used also influence cost. Materials will depend on whether you need exterior or interior basement waterproofing solutions or just a foundation crack repair. After we inspect your foundation, we will explain all your options and work with you and your budget to ensure you are well taken care of.

    Installation of additional accessories

    Accessories such as sump pumps and backwater valves are sometimes required to help drain water away from your house. These are not included in the basic linear foot basement waterproofing cost in Toronto.

    Labour & installation

    Some installation methods are more labor-intensive than others. For instance, exterior basement waterproofing will cost more than interior basement waterproofing simply because it requires more time and labor to fix the leaky foundation issues.

    Average Cost Range for Basement Waterproofing

    When planning to waterproof your basement in Ontario, it’s essential to consider the overall project’s cost. The starting prices for exterior and interior waterproofing are $120 and $75 per linear foot, respectively. However, homeowners should anticipate a broader cost range for a comprehensive project.

    A complete basement waterproofing project might range between $5,000 to $15,000, depending on the basement size, chosen method, and any additional repairs required. This range helps homeowners budget more effectively by considering the full scope of potential expenses.

    For example, the cost to waterproof a 1000 sq ft basement would fall between $5000-$10000 for interior basement waterproofing and usually over $10000 for exterior basement waterproofing. However, the final cost may vary depending on the required scope, additional repairs and other factors.

      Basement Waterproofing FAQ

      Is It Worth to Waterproof a Basement?

      Considering waterproofing prices, investing in basement waterproofing is a valuable decision. Without waterproofing, basements are prone to flooding, especially during severe weather. Effective waterproofing ensures that water is directed away from the foundation, thus mitigating flood risks. This process not only keeps the basement dry, allowing for its optimal use without flood concerns, but also contributes to the overall health of your home.

      Moreover, waterproofing your basement plays a crucial role in managing your home’s moisture levels. High humidity can lead to a warmer atmosphere during summer, and even cause oxidation and damage to the structure. Therefore, mindful of waterproofing prices, it’s crucial to lower your home’s humidity by waterproofing its foundation, ensuring a more comfortable and durable living space.

      What Factors Influence the Basement Leak Repair Cost?

      The cost of basement leak repair is influenced by several factors. The extent of the damage is a primary factor; minor leaks usually cost less to repair than major ones. The repair method is another significant aspect, with options ranging from simple crack injections to more comprehensive exterior waterproofing. The size of your basement and accessibility of the leak area also play a role. The materials used and the contractor rates you choose can also impact the final price. For a specific estimate on basement leak repair costs, it’s best to consult with us to assess your unique situation.
