The City of Toronto Will Pay Up to $6,650 Towards Your Basement Protection

Waterproofing rebates

The City of Toronto’s Basement Flooding Protection Subsidy Program reimburses homeowners up to 80% of the cost of eligible flood protection work — including sump pumps, backwater valves, and more. 

 

That means the upgrade that protects your home and increases its value could cost you a fraction of the price.

 

VMB Group is fully licensed with the City of Toronto and can complete all subsidy-eligible installations — we’ll even help you navigate the application process from start to finish.

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.

How To Save On Basement Underpinning in 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 foundation 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.
  • Explore Financing Options: Some companies offer financing plans, allowing you to spread the cost over time. Additionally, check if there are any government grants or rebates for which you may qualify.
  • Use High-Quality Materials: While it may seem counterintuitive, investing in quality materials can save money in the long run by reducing maintenance and ensuring durability

Is Underpinning a Good Investment?

Underpinning can boost your home’s value by expanding usable space, especially if you turn your basement into an extra unit. Here’s why it might be worth it:

1. No Impact on Zoning Limits

Toronto’s zoning laws set a maximum gross floor area (GFA) for homes, but basements aren’t included in this calculation. Underpinning adds space without affecting your zoning status.

2. Affordable Alternative

Underpinning typically costs up to $50,000, which is more economical than constructing an addition. This approach provides more usable space for the same amount of money, making it a cost-effective solution compared to the high expense of new square footage.

3. Fixes Water Problems

Underpinning can also address basement water issues by adding parging, damp proofing, and vapor barriers, providing a long-term solution for a dry basement.

Overall, underpinning is a cost-effective way to increase your home’s value and solve water problems.

How Much Does It Cost to Underpin a Foundation Yourself?

image1

Taking on the task of underpinning a foundation yourself is not only a significant commitment but also one that might not result in substantial savings. The costs can escalate quickly due to the necessity of specific technical equipment and high-quality materials, regardless of labor expenses.

Underpinning is a complex procedure that demands a high level of expertise to ensure the structural integrity of the building. Therefore, it is crucial that this work is carried out by someone with extensive experience and knowledge in foundation repair to guarantee safety and effectiveness. Additionally, the required equipment, such as hydraulic jacks ($500-$1,500), concrete mixers ($1,000-$3,000), rebar cutters ($200-$500), laser levels ($100-$500), shoring beams ($300-$1,000), and excavation tools ($100-$500), can be quite costly.

Note: Prior to beginning any underpinning project in Ontario, it is essential for homeowners or contractors to secure the required permits from the local municipal building authority. 

FAQs About Basement Underpinning Cost

Yes, underpinning and basement lowering can significantly increase the usable space in your home and add value to your property, making it a worthwhile investment.

The cost can vary, but on average, you might expect to pay between $200 to $350 per square foot. It’s best to get a detailed quote for an accurate estimate.

While a reputable contractor will provide a comprehensive estimate, additional costs can arise from unexpected issues, such as poor soil quality or the need for additional waterproofing.
