Residential Structural Engineer in Montréal
Metra Consultation provides residential structural engineering services in Montréal and throughout Québec for houses, duplexes, triplexes and multi-unit residential buildings. Our engineers assist with renovations, structural openings, foundations, additions, inspections and permit-related structural plans.
1. Removal or Relocation of Load-Bearing Walls
A load-bearing wall is a key component of a building’s structural system, transferring loads from upper floors and the roof to the foundation. In many older residential buildings, it is not possible to identify a load-bearing wall through visual inspection alone.
Removing or modifying a load-bearing wall without structural analysis can lead to cracking, floor settlement, excessive beam deflection, and in severe cases, compromise the overall stability of the building. These issues often appear months after construction is completed.
A structural engineer evaluates load paths, verifies the capacity of existing elements, and designs a compliant replacement beam suitable for permit approval. For this type of project, see our dedicated load-bearing wall engineer service in Montréal.
2. Addition of an Extra Storey
Adding an extra storey is one of the most complex residential projects, as the entire existing structure must be reassessed. Foundations, load-bearing walls, beams, and soil conditions must all be capable of supporting additional loads.
Many older buildings were not designed for increased loads, which can result in settlement or cracking if reinforcement is not properly designed.
A structural engineer evaluates feasibility, calculates loads, designs reinforcements, and prepares permit-ready structural drawings.
3. Foundation Cracks and Building Settlement
Foundation cracks may result from soil settlement, freeze-thaw cycles, poor drainage, or construction defects. It is critical to distinguish between structural and non-structural cracks.
Ignoring structural cracks can lead to progressive deterioration and reduced property value. Cosmetic repairs alone rarely address the underlying cause.
A structural engineer evaluates the observed condition, considers possible causes and recommends the appropriate next step. For foundation-specific concerns, see our foundation and crack inspection service.
4. Pre-Purchase Structural Inspection
A pre-purchase structural inspection helps identify hidden structural issues before acquiring a residential property.
The report can be used as a negotiation tool and may be required by lenders or insurers.
The engineer provides a clear assessment of risks, deficiencies, and potential future repair costs.
5. Reinforcement of Existing Beams and Columns
Many older residential buildings were designed under outdated standards and may not meet current loading requirements.
Warning signs include beam deflection, ceiling cracks, and excessive floor vibrations.
A structural engineer evaluates load capacity and designs appropriate reinforcement solutions to ensure safety and durability.
6. Enlargement of Door and Window Openings
Enlarging door or window openings directly affects the structural behavior of walls, especially when load-bearing.
Without proper engineering design, diagonal cracking or excessive deflection may occur.
A structural engineer determines wall type, evaluates loads, and designs the appropriate lintel or beam.
7. Balconies, Terraces, and Rooftop Decks
Balconies and rooftop terraces impose significant dead, live, and snow loads, particularly in cold climates.
Improper design may lead to excessive deflection, water infiltration, or safety hazards.
A structural engineer ensures proper load transfer, connections, and overall structural safety.
8. Sloped or Sagging Floors
Sloped or sagging floors are often indicators of underlying structural or foundation problems.
Cosmetic repairs do not address the root cause and may conceal serious issues.
A structural engineer identifies the source of the problem and proposes a long-term corrective solution.
9. Conversion of Basement or Garage into Living Space
Converting a basement or garage into a dwelling unit introduces new structural loads to floors, walls, and foundations.
Structural validation is often required by municipal authorities for permit approval.
A structural engineer verifies compliance and ensures the safety of the modified structure.
10. Installation or Modification of Stairs
Installing or modifying stairs often requires cutting floor openings or altering structural members.
Without engineering design, these changes may weaken the structure.
A structural engineer designs the necessary reinforcements to maintain structural integrity.
11. Heavy Equipment and Concentrated Loads
Heavy equipment creates concentrated loads that may overstress residential floor systems.
Structural verification is recommended before installation.
A structural engineer confirms floor capacity and load distribution.
12. Existing Masonry and Brick Walls
Older masonry walls behave differently from modern structural systems and are sensitive to cracking and deformation.
Any modification or new opening requires specialized structural analysis.
A structural engineer provides appropriate structural solutions for masonry structures based on the existing conditions and proposed work.
Starting a Residential Structural Project
Send us the property address, available architectural drawings or sketches, photos of the existing conditions and a description of the proposed modification or concern. If the project requires municipal approval, see our engineering plans for permit service. For a broader review of an existing structure, see our building and structural inspection service.
