Underpinning Costs Breakdown

When you decide to complete the basement underpinning in Hamilton, you definitely want to know how much it will cost. As you may guess, reinforcing a building’s foundation can be quite an expensive renovation. Especially when you want it done right and use top-quality materials. The expenses for basement underpinning vary widely and are influenced by factors such as soil type, property size, and others.

We all know how expensive real estate is in Canada. No wonder more and more people decide to do a home renovation project rather than buy a new flat or house. It is indeed challenging to add a floor on the roof, so a basement is your best option.

However, the actual cost of underpinning and lowering the basement can also be expensive. Here, we gathered some tips to lower it. One of them is to contact an experienced WillFix basement waterproofing contractor! We are sure we can help you with any basement issue for a reasonable price.

Basement Underpinning Definition

Basement underpinning is a construction technique used to increase the depth or strengthen a building’s existing foundation. It involves excavating below the existing foundation and constructing additional support to enhance structural stability. You should start this process when a building’s foundation has cracks or begins to change due to soil movement, aging, or changes in the load-bearing capacity.

Underpinning Process

The basement underpinning has several stages, each crucial for achieving a successful outcome. Here’s a brief overview:

• Site Inspection and Evaluation

WillFix structural engineer assesses the existing foundation, identifies structural issues, and determines the appropriate underpinning method.

• Detailed Design and Engineering

Our team develops a detailed design plan, including calculations, reinforcement requirements, and excavation specifications.

• Excavation and Shoring

The underpinning process finally begins with excavating the soil beneath the existing foundation, often done in sections to maintain stability. Builders install temporary shoring supports to prevent collapses.

• Underpinning and Reinforcement

New footings or piers are constructed beneath the existing foundation to strengthen it. Depending on the project’s requirements, this involves using concrete, steel beams, or helical piles.

• Waterproofing and Finishing

Once the underpinning is complete, our team will implement waterproofing measures and finish the basement according to the desired design and functionality. Read more about future water damage protection tips in our previous article, How To Protect Your Home From Water Damage.

This information is extremely generalized. But you can rest assured that our skilled team will answer all your questions and explain in plain language what is going on and what further steps will be.

Maximizing Home Value with Basement Lowering and Underpinning

Lowering and underpinning a basement increases a home’s value by making it more accessible and comfortable and improving the overall strength of the building. Typically, basements are around 6 feet high, which can be quite limiting. Imagine adding 2 feet, achieving a total height of 8 feet! The space becomes much more practical and comfortable.

I also heard about basement benching. What is it?

Both benching and underpinning have their distinct benefits and applications. Benching is often seen as a quicker and less costly option. During the benching, you create extra space without altering the foundation depth. However, it’s important to note that benching reduces the usable interior space. 

Many homeowners prefer the underpinning process because it can 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.

Factors Affecting Basement Underpinning Costs

Multiple factors influence the cost of underpinning and lowering a basement. They also vary from one project to another, affecting both the complexity and the price of the work. Knowing what you are paying for in advance helps you estimate and plan your budget accordingly. 

That’s what influences underpinning expenses:

• Structural analysis and design to ensure your foundation lasts a lifetime;
• Complexity of the underpinning method used;
• Depth and breadth of excavation required;
• Soil type, which affects stability and digging efforts;
• Local building code requirements impacting construction practices.

Our WillFix team approaches each project with meticulous care, as if we are working on our own home. That’s why we guarantee effective waterproofing in Toronto to safeguard the structure’s longevity.

Average Cost of Basement Underpinning

As we said earlier, basement underpinning cost varies significantly depending on the specific requirements of each project. Prices range between $200 and $400 per square foot. However, it’s important to note that this is a general estimate, and obtaining detailed quotes from reputable contractors like Will Fix is crucial for accurate pricing.

What Additional Costs Are There?

In addition to the linear foot cost, there are several other expenses to consider, including but not limited to:

• Excavation and shoring costs;
• Engineering and architectural fees;
• Material costs (concrete, steel, etc.);
• Waterproofing and drainage solutions;
• Finishing and restoration work.

You would only calculate some things yourself. Plus, no one cancelled unforeseen circumstances. Even if you have received a nice and accurate estimate, during the excavation process, ground waters may rise, or something else may happen. We recommend always being patient, controlling the work performed and trusting our professionals.

Tips to Make Basement Lowering Affordable

It’s ok if you want to cut back on foundation costs, especially if you are on a tight budget. We have to admit initial costs can be surprisingly huge and disturbing, but it is definitely worth it. Plus, there are effective ways to manage and reduce these costs without compromising on quality. For example:

1. You should compare quotes from various contractors. In such a manner, you can find the most competitive price and know the range of services offered;
2. You can complete some tasks yourself. Painting a wall, minor finishing work, or even cleanup aren’t subbranches of rocket science. Yes, you’ll definitely waste more time, and the result won’t be perfect, but you’ll save a lot!;
3. It is a pro tip, but try looking for deals on source materials. Sometimes, you can purchase supplies yourself, and they will be much cheaper than going through a contractor;
4. Consider timing and seasonal discounts, as we may provide affordable special offers during off-peak seasons or slower periods;
5. Finally, just create a well-thought-out plan. This will reduce the waste of materials and time, which in turn will lower overall costs.

Obviously, thoughtful planning and smart decision-making effectively reduce the cost of underpinning and lowering your basement. It is also a great idea to save money for some time and hire a professional contractor. You won’t think where to get materials or how to clean the house. With Will Fix, you can just lean back and relax while professionals handle the job from A to Z.

Alternative Underpinning Solutions and Their Expenses

Home renovation isn’t limited by underpinning cost only. There are additional methods that can be cheaper upfront but will require more maintenance in the future. Thus, mass concrete underpinning might cost less upfront but could lead to more labour spending over time. The process involves digging box-shaped pits under existing foundations and filling them with concrete. It’s labour-intensive but uses simple materials. The costs are mainly tied to manual work and the amount of concrete used. Beam and base solutions may offer savings on labour costs despite potential increases in material expenses.

Non-invasive basement renovation techniques

Resin injection is a noninvasive technique with unique cost implications. It stabilizes foundations by injecting resin into affected soil areas, which expands and hardens. This process causes minimal disruption compared to traditional methods. It’s particularly effective where conventional excavation is impractical or too expensive.

Screw pile benefits

Screw piles present financial benefits when conditions are right. They are fast to install with minimal disturbance, translating into direct labour savings for a project. 

For new construction or areas requiring swift stabilization, screw piles are an economical choice for substantial foundation solution cost reductions.

Screw piles not only reduce installation time but also lessen the need for large machinery onsite, further cutting down on costs associated with placement and changes during construction phases.
