Maximizing Home Value with Basement Lowering and Underpinning

Lowering and underpinning a basement increases the value of a home by making it more accessible and comfortable and improves the overall strength of the building. Therefore, it is important for homeowners who are thinking about these repairs to understand the benefits and features of the process.

Benefits of basement lowering

Basement lowering presents several advantages for homeowners. Typically, basements stand at around 6 feet high, which can be quite limiting. By lowering the basement by an additional 2 feet, achieving a total height of 8 feet, the space becomes much more practical and comfortable. This adjustment can dramatically transform the basement into a more versatile and inviting area of the home.

In terms of structural renovations, underpinning is a basic thing. It serves to reinforce the foundation, thereby improving the stability and safety of the entire home. This process secures the existing structure and prepares the basement for future renovations or conversions.

When comparing benching and underpinning, each has its distinct benefits and applications. Benching is often seen as a quicker and less costly option. It involves creating extra space without altering the foundation depth. However, it’s important to note that benching can reduce the usable interior space. 

The underpinning process is preferred by many homeowners due to its ability to transform the basement into a rentable space or a fully finished area. This method requires detailed engineering work and sequential excavation to ensure the structural safety of the home.

The underpinning process typically begins with the acquisition of engineer drawings and permits. Further, it is followed by the excavation of soil to the new elevation and the installation of supports as per the engineering plans. It also includes the installation of new systems such as plumbing and interior drainage, as well as laying a new concrete floor.

The Real Cost of Basement Underpinning and Lowering

Both basement lowering and underpinning offer significant benefits. These range from increasing usable living space to enhancing the overall value and safety of your home. While benching is a suitable option for certain situations, underpinning is often the preferred choice due to its advantages.


Having an idea of the cost of underpinning and lowering the basement is half of the success of project planning. It’s an investment not just in terms of money but also in enhancing your home’s value and functionality. By considering all factors and planning accordingly, you can make this ambitious project a reality within your budget.
