Underpinning

Structural Foundation Strengthening in Ontario

Queens Home provides professional underpinning services across Ontario for homeowners looking to strengthen existing foundations, increase basement ceiling height, and create additional usable living space. Underpinning is a highly specialized structural process that extends and reinforces your home’s foundation, making it safer, stronger, and more suitable for basement renovations or legal basement apartments.

Whether your goal is to lower your basement floor, fix foundation settlement issues, or prepare for a full basement renovation, our team manages the entire process from engineering and permits to excavation, concrete work, and final structural completion.

We also handle all required permits, structural engineering coordination, municipal inspections, and code compliance, ensuring every underpinning project meets Ontario Building Code requirements and safety standards.

What We Handle

Basement Lowering & Ceiling Height Increase

We excavate beneath the existing foundation in controlled stages to lower basement floors and increase ceiling height, making the space suitable for comfortable living areas and legal basement units.

Foundation Extension & Reinforcement

We extend and reinforce existing foundations using engineered concrete systems that improve structural stability and support long-term building loads.

Structural Engineering Coordination

We work closely with licensed structural engineers to ensure all underpinning designs, load calculations, and construction methods meet Ontario safety requirements.

Legal Basement Preparation

We prepare basements for legal secondary suites by meeting minimum height requirements, structural safety standards, and municipal building regulations.

Excavation & Soil Removal

We carefully excavate in sections beneath your foundation to maintain structural integrity while safely removing soil and preparing for new foundation work.

New Concrete Footings & Foundation Walls

We install reinforced concrete footings and foundation wall extensions that permanently strengthen and deepen the existing foundation system.

Basement Floor Replacement

We install new concrete basement floors designed for durability, proper leveling, and future finishing or renovation work.

Waterproofing & Drainage Upgrades

We integrate waterproofing systems, drainage improvements, and moisture protection solutions to help prevent water intrusion and foundation damage.

Structural Repairs & Crack Correction

We repair existing foundation cracks, settlement issues, and structural weaknesses discovered during the underpinning process.

Permit & Inspection Management

We manage all permits, engineering approvals, and municipal inspections required throughout the entire project.
