What is Basement Underpinning?


In Oakville, basement lowering involves the essential reinforcement and lowering of your basement’s foundation. This critical process combats foundational weakening due to factors such as pest infestations, leakages, and structural faults, safeguarding your home’s stability. Excavating soil beneath your basement and adding new concrete below the initial foundation not only strengthens your home but also gifts you with more spacious underground space to tailor according to your desires.

Framework for Estimating Basement Underpinning Cost

  1. Initial Consultation and Inspection Fee: Some contractors might charge for a preliminary assessment of your property to identify the scope of underpinning required. This could range from $0 (if the consultation is free) to approximately $500, depending on the provider.

For a typical home, total underpinning costs could start from $20,000 and can go upwards of $100,000 for extensive projects.
  4. Additional Services: Costs for additional services like waterproofing, sump pump installation, and basement walkouts can add to the total estimate. For example:

Basement underpinning is much more than just reinforcing your home’s foundation; it’s about transforming and enhancing every aspect of your basement to suit your lifestyle and needs. Understanding that each Oakville home is unique, we extend a range of additional services designed to complement the basement lowering process and elevate your space to new heights of functionality and safety.

Exterior Waterproofing

A dry basement starts with robust exterior waterproofing. Our service is designed to shield your home against moisture by meticulously sealing the exterior walls of your basement. This step is particularly crucial for homes with complex architectural features or shared walls, where the risk of moisture seepage is higher. With our team’s expertise, every nook and cranny is considered and protected, ensuring your basement stays dry and cozy, regardless of the weather outside.

Installing Sump Pump

Water has a way of finding the path of least resistance, often leading straight to your basement. Our sump pump installations provide an efficient exit route for unwanted water, directing it away from your foundation and keeping your basement dry. This not only prevents water damage but also wards off the potential for mold growth, ensuring the air quality in your home remains clean and healthy.

Relocating The Current Heating System

The design and layout changes that often accompany basement lowering can affect the placement and efficiency of your home’s heating system. Our team excels in evaluating and relocating heating elements, from water heaters to HVAC systems, to harmonize with your newly configured space. We take into account factors such as operational efficiency, safety, and your specific heating requirements to guarantee your comfort in every season.

Basement Walkouts

Transform your basement into an easily accessible, versatile space with a custom-designed basement walkout. This feature not only makes your basement more functional — perfect for an independent rental unit or a direct connection to your backyard — but also significantly increases your home’s value. Our comprehensive approach covers everything from planning and excavation to construction, all tailored to fit seamlessly with your home’s existing design and local zoning laws.
