Basement Underpinning Cost Toronto 2024

What Is Basement Underpinning?

Basement underpinning is a construction process aimed at reinforcing or deepening the foundation of an existing building. This method is often employed to strengthen the building’s structural integrity, address foundation issues, or to increase the basement’s depth. 


Lowering the basement, a component of underpinning, involves excavating the existing basement floor to increase ceiling height, creating more usable living space or making the area more comfortable and functional. 


How Much Does Basement Underpinning Cost In Toronto?

In Toronto, basement underpinning typically costs between $80 to $500 per linear foot. For a standard project, this translates to a total expense ranging from $20,000 to $50,000. For precise costing tailored to your specific project, it’s best to consult directly with a professional underpinning service.


Factors Affecting The Cost


  1. Foundation Type: The construction material and condition of the existing foundation affect the complexity and cost.
  2. Depth of Excavation: The increased depth requires more labor, time, and materials, directly impacting the price.
  3. Structural Modifications: Any changes to the home’s structure, such as adding support beams, will add to the cost.
  4. Materials: The quality and type of materials used for underpinning and reinforcing the structure play a significant role in total expenses.
  5. Labor: Skilled labor is essential; the experience and expertise of the contractors can influence the project’s cost.
  6. Permits and Engineering Plans: Local building permits and professional engineering plans are necessary and contribute to the overall expense.
  7. Accessibility and Site Condition: Difficult access to the worksite or challenging soil conditions can increase labor and equipment costs.
  8. Additional Features: Waterproofing, insulation, and interior finishing are often part of basement lowering projects and affect the final price.

How To Save On Basement Underpinning & Lowering Toronto?

Basement underpinning and lowering in Toronto can be a significant investment in your property. However, there are several strategies to help manage costs and achieve savings without compromising on quality or safety:

  • Plan Everything: Begin with a detailed assessment. Identifying potential challenges early can prevent expensive changes mid-project. Engage a reputable engineer or underpinning specialist for accurate planning.
  • Obtain Multiple Quotes: Don’t settle on the first quote. Approach several reputable companies for estimates to compare prices, services offered, and included extras. This can help you find the best value for your investment.
  • Bundle Services: If you plan to waterproof or finish your basement, ask if there are savings for bundling these services with underpinning. Some companies offer discounts for comprehensive projects.
  • Opt for Off-Peak Timing: Some contractors offer reduced rates during slower business periods. Scheduling your project during these times could lead to cost savings.

We had a great experience with the VMB Group and would highly recommend them for anyone looking to waterproof / underpin their basement. Mike worked with us from the beginning to understand the options, pricing, timelines etc., and kept us up-to-date on progress using the Monday app. We started with a wet, dark basement around 6'2, and finished with a waterproofed, dry 8'3 basement and we couldn't be happier with the result. Nothing was over the original quoted prices, and everything was done quickly and on time.Note: two of the attached pictures show the before, and one is the after with the radiant floor heating installed, just before the concrete slab pour.
