Why You Need Basement Lowering Toronto

Basement Lowering/UnderpinningIf your home does not have enough space; consider basement underpinning, which is also commonly referred to as basement lowering. A finished basement can add up to three more functional areas to your existing house space. The problem of a low ceiling is often present in older homes’ basements since this space was usually used for utilities, fortunately, converting crawl space into a finished basement can be achieved by lowering the floors and underpinning the foundation.


In construction, basement lowering is the process of strengthening and stabilizing the foundation of an existing house or other structure like a basement.

Basement lowering, or underpinning, is a complex project that requires proper planning and preparation. It usually takes over four weeks to complete the project. Since lowering and underpinning imply excavation, the best time to start working on your basement is the dry season, usually the middle of a summer. Basement lowering involves changing your house’s structure, it can only be performed by a professional foundation contractor with a specific (to lowering and underpinning) liability insurance license, knowledge and equipment. If your basement lowering and underpinning project is not properly done, it can destabilize the foundation and cause the collapse of the structure.

Before you call the basement foundation contractors, think of the reasons why you would like to undertake the basement lowering project it can increase your home’s value, to add extra living space, or to create additional storage. When a basement foundation contractor has this information, they’ll be able to come up with a viable plan, which will then go a structural engineer, who will, in turn, create drawings of your future basement.

The drawings are necessary to get a permit to start your basement lowering and underpinning project, from a city. Once the city approves the project, the basement foundation contractor will make necessary changes and will able to give you a quote for the lowering project.

Among the factors affecting the project could be the size of your basement, the height you are trying to achieve, the landscaping conditions around your house, the season, and the soil quality. When the price of the project is settled between you and the contractor, either you or the contractor will have to talk to your neighbours to make sure your project is not compromising the structural stability of their homes. Once you complete all the formalities of your basement project, the specialist will start the basement lowering by stabilizing the foundation footing (to avoid problems associated with excavation).

The basement lowering process entails locating the water supply and sewer lines, drains; the removal of the concrete floor; excavation; drain system relocation, floor drain, and sump pump installation. The underpinning process strengthens and stabilizes the foundation footing of the house. By increasing the depth of the foundation, it provides an even distribution area for the soil load.

After the basement lowering is completed, preparation is made for interior renovation efforts associated with the goals of your basement project (like adding a bedroom or a bathroom, installing pipes, etc.)
