Nusite Group: Toronto’s Trusted Underpinning Experts with Three Decades of Experience

When it comes to basement underpinning and foundation work in Toronto, few projects are as complex, technical, or potentially dangerous as lowering a basement floor. This specialized construction process requires not just technical expertise, but decades of hands-on experience to navigate the countless variables and potential hazards that can arise. For over 30 years, Nusite Group has established itself as one of Toronto’s leading underpinning contractors, earning recognition for their ability to safely and successfully complete both residential and commercial underpinning projects of any complexity.

The Critical Importance of Experience in Underpinning Work

Basement underpinning, also known as basement lowering, is far more than simply digging out soil beneath an existing foundation. This involves carefully excavating the soil beneath your basement, reinforcing or extending the basement walls, and ensuring the structural integrity of the building throughout the process. The complexity of this work cannot be overstated, as it requires intimate knowledge of soil conditions, structural engineering principles, proper shoring techniques, and sequential excavation methods.

There have been several well documented disasters in Toronto involving unqualified contractors and houses falling down due to improper shoring during the basement lowering process. These incidents underscore why choosing an experienced underpinning contractor isn’t just important—it’s absolutely critical for the safety of workers, residents, and neighboring properties.

The dangers associated with inexperienced underpinning work are severe and well-documented.The collapse may affect other neighboring houses.

Nusite Group’s Three Decades of Underpinning Excellence

Established in 1990, Nusite Group brings over 30 years of specialized experience to every underpinning project. This extensive experience has allowed them to develop proven methodologies and safety protocols that ensure successful project completion while minimizing risks.

Nusite Contractors are basement lowering experts in Toronto and have successfully completed hundreds of underpinning projects in Toronto and the GTA and can provide references upon request. This track record of successful projects demonstrates their ability to consistently deliver quality results across a wide range of project types and complexities.

Comprehensive Underpinning Services for Residential and Commercial Clients

Nusite Group offers complete underpinning services for both residential and commercial applications. Their expertise spans the full spectrum of basement lowering needs, from simple residential basement conversions to complex commercial foundation reinforcement projects.

This approach is particularly valuable in Toronto’s expensive real estate market, where maximizing existing space is often more cost-effective than relocating or building additions.

Their commercial underpinning capabilities are equally impressive, handling large-scale projects that require specialized knowledge of commercial building codes, complex structural requirements, and the coordination of multiple trades and inspections.

Technical Expertise and Safety Protocols

What sets Nusite Group apart from less experienced contractors is their comprehensive understanding of the technical complexities involved in underpinning work. The basement lowering process begins with a detailed assessment of your existing foundation and soil conditions. Once we have a clear understanding of the structure, our team systematically excavates and lowers the basement floor while reinforcing the basement walls to maintain the safety and stability of the home.

Nusite’s approach follows the established industry practice of sectional underpinning, which is critical for maintaining structural integrity throughout the process. After acquiring proper engineering and city-approved drawings, the existing basement will now be divided into vertical sections. These sections are marked as 1, 2, 3, 4 over and over again… A contractor will pick a number. For example, they can pick the number 2. All the sections that have been marked 2 will be cut and excavated. The sections are then formed, and new concrete is poured into the lowered height.

This methodical approach ensures that the building’s structural integrity is never compromised, as only specific sections are excavated at any given time while the remaining foundation continues to support the structure above.

Understanding the Risks of Choosing Inexperienced Contractors

The underpinning industry in Toronto has unfortunately seen an influx of contractors who lack the necessary experience and expertise to safely perform this critical work. Using an inexperienced underpinning contractor or trying to turn it into a DIY project is a recipe for disaster. The consequences of choosing the wrong contractor extend far beyond poor workmanship—they can result in catastrophic structural failure.

Basement underpinning involves a lot of risky activities that may cause injury to the personnel on the ground. According to recent observations, many people have lost their lives, and others left seriously injured as houses collapsed on them during underpinning. These risks are significantly heightened when contractors lack proper training, equipment, or understanding of safe excavation procedures.

Financial risks are equally concerning. If you hire an unqualified and under-insured contractor, you the homeowner will bear most of the responsibility and legal consequences if workers or civilians get injured due to negligent work. This liability exposure can result in devastating financial consequences for property owners who choose contractors based solely on price rather than qualifications and experience.

Outstanding Customer Reviews and Industry Recognition

Nusite Group’s commitment to excellence is reflected in their consistently outstanding customer reviews across multiple platforms. They maintain high ratings on both HomeStars and Google, with customers frequently praising their professionalism, expertise, and attention to safety.

The quality of their underpinning work is evident in customer testimonials that highlight not just successful project completion, but the peace of mind that comes from working with experienced professionals. Justin from Nusite came to evaluate solutions after some water damage in my basement… given delays during the job to organize different trades outside of their control, I think the task was completed reasonably close to the time estimate.

Comprehensive Project Management and Professional Standards

Beyond their technical expertise, Nusite Group provides comprehensive project management that addresses all aspects of underpinning work. This includes coordination with structural engineers, management of city permits and inspections, and integration of waterproofing systems that are essential for long-term basement performance.
