What is Basement Underpinning?

Put simply, with basement lowering, we’re taking out your old foundation, digging down to create more space, and then building you a new, stronger foundation. You can underpin a portion of your basement to deal with an area that’s been structurally compromised or lower the entire room to create a comfortable living space to enjoy. Basement underpinning solves a wide range of problems, like perpetual mould, foundation cracks, subsidence, and flooding. Older homes may need to repair a failing foundation, or you may find your current foundation simply isn’t strong enough to support an additional story.

The basement underpinning process takes precision, experience, and attention to detail. Your home must be assessed and a plan must be created to adequately support the structure while you remove the old foundation and pour new footings. You need permits, a structural engineering report, architectural drawings, and periodic inspections to ensure everything is up to code.

Benefits of Basement Underpinning

Easier, More Affordable Option to Increase Usable Living Space

Regardless of the reason you decide to consider whether or not an underpinning foundation project is right for you, there are some key benefits you should be aware of. Real estate prices are creeping up every year, and moving may not be an option for many people. If your family has outgrown its starter home or you’re looking for a mother-in-law suite to rent out or comfortably house an elderly parent, the first thing that pops into most people’s minds is installing an addition.
An underpinning basement project gives you the same outcome at a much lower price. Permits and materials are less expensive, because you’re not building a whole new structure and tying it into your existing home. You’re simply modifying an existing structure and making it stronger.

Increase Property Value and Get a Better Return On Your Investment

Our underpinning specialists help you chart a course toward a better return on your real estate investment. You’ll get a better price on a property that’s undamaged, modernized, and not a fixer-upper. Repairing structural damage to your foundation and basement walls is the first step in boosting your home’s value. Buyers are turned off by faulty sump pump systems and wet, musty basements that are cramped and poorly lit. Obvious mould or conditions that foster mould growth will stop most potential buyers from considering your house as a viable future home for their families. Finishing your basement space adds valuable liveable square footage to your home, making it infinitely more attractive than houses with unfinished basements.

Strengthen Your Foundation

Over time, even the best-laid foundations can develop cracks, sagging areas, and leaks. Harsh winters, torrential rain, and flood events all take a toll. Inadequate or incorrect types of waterproofing applications in your basement can also degrade your foundation and the walls that support your house. Older foundations may be too thin to support additional upper stories and generally need structural upgrades to help them stand up to earthquakes more effectively. Another common reason to beef up your foundation is when the soil your house is built on has shifted, causing structural instability.

Upgrade Your Waterproofing to Prevent Damage

Many older waterproofing methods can cause damage, weakening your foundation and basement walls. Properly installed modern waterproofing will limit water damage to your foundation, home, and possessions. The first step in effective waterproofing is to find the source of your leak problem and prevent it from permeating the concrete that makes up your footers, foundations, and concrete walls. Concrete is a porous material, and moisture will, over time, pass from the outside to the inside of your basement. Another perk of upgrading your waterproofing is that it may get you rebates or financial incentives from your local government agencies.

Upgrade Outdated Plumbing, Wiring, and Insulation

During the basement lowering process, your space is laid bare, exposing plumbing pipes, drainage systems, and wiring, making it the perfect time to upgrade outdated items. Not only will you see an improvement in how things work in the basement, but you’ll also benefit from a home value bump. Prospective clients appreciate knowing these crucial systems are modernized and will not become an expensive money pit six months after moving in. You can also add attractive options like radiant floor heating, check valves that prevent sewage from backing up into your basement, and improve insulation to cut down on heating costs.

Boost Ceiling Height and Get Better Lighting

Lowering basement floors gives you higher ceilings, banishing that claustrophobic cramped feeling that many basements have. Without increasing the depth of your basement floor, refinished spaces in the basement often feel subconsciously oppressive. It can also help you get better lighting and find a better option than a single bare bulb with a metal pull chain. Even though you’re digging deeper, it creates more space for additional windows or bigger windows to let natural light flood your new space. The increased headroom gives you more options for overhead lighting and ceiling fans that help dissipate moisture and distribute heat effectively.

The Permit Process Is Less Expensive and Complicated Than Building an Addition

The permit process is faster and less expensive for underpinning compared to getting permits for building an addition to your house. In Mississauga, you can expect to pay around $2,200 for a permit and get it approved in about three weeks. Construction permits vary a lot, depending on how complex your project is. This makes the approval time much longer and can cost you somewhere between $4,000 to $10,000 to get your permits and drawings done.

Basement Underpinning Process

Assessment, Planning, and Permits for Basement Lowering

For safety reasons, building codes apply to basement underpinning, just like they do to other types of construction. After assessing your site, our team of qualified basement lowering experts can help guide you through the permit process and streamline communication and coordination with your structural engineer and architect.

Secure Your Possessions

It’s important to have a clear space to work in, and we’ll need you to remove any stored household goods and furniture from the basement before we begin work. During part of the basement lowering process, your basement may be open to the elements. Our team will let you know ahead of time how much needs to be removed and which areas must be free of obstacles.

Basement Demolition

During this phase of the project, we take out your old floors, remove non-load-bearing walls, install temporary shoring to support your home while we work, and tear out systems that will be updated. We also excavate and remove the dirt under your slab.

Underpinning the Foundation in Sections

In order to keep your structure stable, underpinning foundations happens in sections. The structural engineer carefully marks off three- to four-foot sections, labelling them 1, 2, or 3. To start, all the sections marked with a 1 get dug out to the appropriate depth. Forms are built to create the desired type of footing and concrete is poured. When all the first sections are complete, work begins on the group of sections marked with a 2. These steps are repeated until all sections have been retrofitted and new footings are complete. This is also when load-bearing walls are replaced. Expect periodic inspections by the structural engineer to ensure everything is going according to plan.

Drainage, Waterproofing, and Upgrades

Lowering your foundation means you have to install lower drains as well. Delta waterproofing membranes are applied to the walls, and we often reroute plumbing at this time to accommodate new fixtures. We’ll install new wiring and upgrades like radiant heat floor systems, and put in sewage ejectors if they’re needed. After putting in your sump pump, we’ll lay down a layer of gravel and a vapour barrier before pouring your new concrete floors.

Cleaning Up the Work Area

It’s important we leave you with a space you can put to use right away. Once work is finished, we’ll clean up after ourselves. This includes removing the excavated dirt and pieces of old concrete flooring from your site.

About Mississauga

Mississauga sits along the shore of Lake Ontario, bordering the western side of Toronto. As of 2021, Mississauga had approximately 717,000 residents, making it the third most populated city in Ontario.

Mississauga covers an area of about 292 square kilometres, including 13 kilometres of Lake Ontario’s shoreline. On average, Mississauga experiences about six snow-free months per year, with occasional snowfall in May and October which rarely sticks to the ground. Mississauga is located in plant hardiness zone 6B, meaning its ground freezes frequently.

Underpinning services can be performed in Mississauga almost year-round, except in the case of inclement weather. Permits for underpinning are available in person when visiting a Municipal Service Center, or by applying online through the ePlans website.

Remember to supply information such as:

  • The cost to perform the work
  • Your project duration
  • Project drawings and plans
  • Site or scale drawing to determine property setback requirements

Is Basement Underpinning Expensive in Mississauga?

Typically, your contractors will analyze your property’s size (in square footage) and the linear footage of its basement walls in order to determine the total cost of the project. However, some contractors may choose to estimate the project cost through stages, including:

  • Accumulating drawings, permits, and other paperwork
  • Inspecting the condition and composition of the soil
  • Preparing the Site
  • Wall underpinning
  • Basement slab work
  • Demolition
  • Crack Repairs
  • Remediation and site cleanup

You will need to hire a professional architect or structural engineer for the permit application process, as detailed drawings will be required for your permit. These experts in underpinning can also provide other valuable documents, such as the size of your existing concrete pad, as required by Mississauga’s Building & Construction Authority.

Typically, the cost of these drawings and the entire process ranges from $2,500 to $3,500. However, depending on the nature of the project, this amount can easily increase to $4,500, or more.

After you receive your drawings, underpinning experts can evaluate your project and recommend a course of action.

Homeowners and business owners in the Mississauga area should budget for about $80.00- $350.00 per square foot on average for an underpinning project. Most underpinning projects performed in Mississauga will cost between $15,000 and $30,000.

What Variables Affect the Cost of Underpinning in Mississauga?

Some of the most common variables that can affect the cost of underpinning in Mississauga include:

  • The Underpinning Company You Choose
  • The Location of Your Property
  • The Type and Condition of the Soil
  • The Length and Width of Your Basement
  • Accessibility to the Site
  • Method of Underpinning Used
  • Structural Materials and Quantity Required

Generally, these variables will have the biggest impact on your total cost of underpinning.
