If you’re considering a basement renovation, one of the most important aspects is maximizing the space. Many homeowners in Toronto and the Greater Toronto Area (GTA) want to create additional usable space in their basements. One of the key challenges in basement renovations is ceiling height. If the ceiling is too low, it can make the space feel cramped and uncomfortable, limiting its potential.
Two popular methods for increasing basement ceiling height are underpinning and benching. Each method has its own advantages, disadvantages, and cost implications. In this article, we’ll break down the differences between underpinning and benching to help you decide which method is right for your basement renovation project.
What is Underpinning?
Underpinning is a process that involves digging down beneath the existing foundation of a building to lower the floor of the basement and increase the height of the space. This method is commonly used in older homes where the basement ceiling is too low to meet modern standards, or in situations where a homeowner wants to add more headroom to make the space more functional.
How Underpinning Works:
Underpinning involves removing the existing concrete floor in sections and then digging out the soil beneath it. New foundation walls are poured at a lower level, and a new floor slab is installed. The process typically happens in stages to ensure the stability of the structure and prevent damage to the rest of the building.
Advantages of Underpinning:
| Advantage | Description |
|---|---|
| Significant Height Increase | Underpinning can add substantial height to your basement, depending on how much you dig down. This method can increase the ceiling height by 2 to 3 feet or more. |
| Adds Value to Property | Increasing your basement height can make the space more functional, adding value to your property. It makes the area more suitable for living spaces such as an apartment or home office. |
| More Flexibility for Design | Once the basement ceiling is raised, you’ll have more flexibility in how you design the space. You can add full-height ceilings, tall windows, or even a second level in some cases. |
Disadvantages of Underpinning:
| Disadvantage | Description |
|---|---|
| High Cost | Underpinning is one of the most expensive methods for increasing basement height due to the complexity of the work and the need for specialized contractors. It may cost anywhere from $15,000 to $50,000 or more, depending on the scope of the project. |
| Disruption and Time-Consuming | The process is highly disruptive, often requiring a few months of work. The basement may be unusable during this time. |
| Requires Professional Help | Underpinning requires specialized knowledge and skill, so you will need to hire a licensed contractor and structural engineer, which can increase costs. |
What is Benching?
Benching is another method used to raise basement ceilings, but it involves a different approach than underpinning. Rather than lowering the floor, benching involves excavating a series of steps or “benches” around the perimeter of the basement. These steps help to create more headroom in certain areas while maintaining the existing floor level in other areas.
How Benching Works:
Benching involves cutting into the basement floor at specific points and creating stepped levels that gradually slope down towards the foundation walls. Unlike underpinning, benching doesn’t require the removal of the entire floor. It’s a less invasive option for increasing basement height in select areas.
Advantages of Benching:
| Advantage | Description |
|---|---|
| Lower Cost | Benching is generally less expensive than underpinning because it doesn’t require extensive excavation or foundation work. It is more cost-effective for smaller projects. |
| Less Disruption | The benching process is typically less disruptive than underpinning because it doesn’t require major structural changes. Your basement may be usable during some parts of the project. |
| Suitable for Specific Areas | Benching allows you to target specific low spots in the basement, rather than having to lower the entire floor. This can be useful if only part of the basement has low ceilings. |
Disadvantages of Benching:
| Disadvantage | Description |
|---|---|
| Limited Height Increase | Benching doesn’t provide the same significant increase in ceiling height as underpinning. It typically adds around 1 to 2 feet of headroom, making it less effective for creating a full-height basement. |
| Complexity | While benching is less invasive than underpinning, it still requires skilled labor and precise excavation. The benches must be carefully planned and executed to avoid compromising the structural integrity of the home. |
| May Not Be Suitable for All Homes | Benching is not always an option for homes with very shallow foundations. It may also not be practical if there are already major obstacles such as large support beams or existing plumbing that cannot be adjusted. |
Underpinning vs. Benching: Which Is Better?
Choosing between underpinning and benching depends on several factors, including your budget, the height increase you desire, the structural limitations of your home, and your overall renovation goals. Below is a quick comparison to help guide your decision:
| Feature | Underpinning | Benching |
|---|---|---|
| Cost | Higher ($15,000 – $50,000+) | Lower ($5,000 – $20,000) |
| Height Increase | Significant (2-3+ feet) | Moderate (1-2 feet) |
| Disruption | High (longer project duration) | Low (less disruption, can be done in phases) |
| Design Flexibility | High (full-height ceilings) | Moderate (targeted areas for increased height) |
| Construction Time | Longer (a few months) | Shorter (weeks to a couple of months) |
| Ideal For | Larger basements or full-height conversion | Smaller basements or partial ceiling increases |
Which Option Should You Choose?
- Go for underpinning if you want to create significant height in your basement, especially if you’re looking to transform your space into a full-height living area with added rooms or living space.
- Opt for benching if your goal is to increase height in specific low spots or if you have a smaller budget and are looking for a more cost-effective solution with less disruption.
Both methods can be effective for increasing your basement height, but choosing the right one depends on your specific needs, the structure of your home, and your budget. It’s important to consult with a professional contractor or structural engineer to assess which option is best for your basement.
Conclusion
Whether you choose underpinning or benching, both methods offer significant benefits for homeowners looking to add height to their basements. Underpinning provides more dramatic changes but comes with higher costs and longer timelines, while benching offers a more affordable and less disruptive option, albeit with a more limited height increase. By weighing your options and understanding the costs and benefits, you can make an informed decision that meets both your budget and your home improvement goals.
