Scope tied to the building—not a regional generalization
We inspect visible and accessible components and explain findings in language an owner or buyer can use. Regional context helps guide due diligence; it never establishes that an issue exists at a particular address.
Issues that may be relevant in Greater Montréal
The following items are provided to guide questions and follow-up. Their relevance depends on the specific location, site, age and building characteristics.
Pyrite in certain under-slab fills
Pyrite-bearing fill can expand and contribute to cracking of slabs or partitions. Visual indicators may justify further investigation, but they cannot identify the material or determine its swelling potential. Laboratory characterization and specialist assessment remain appropriate when conditions warrant.
Heavy rainfall, drainage and sewer backups
In urban areas, below-grade garage entrances, floor drains, backwater valves, catch basins and sewer laterals can affect basement vulnerability. An inspection reviews accessible components and evidence of past events, but does not simulate intense rainfall or confirm municipal system capacity.
Altered buildings and complex envelopes
Additions, plex conversions, masonry façades, flat roofs and equipment added over time create interfaces that deserve attention. A coordinated review of the envelope, drainage, systems and available records helps distinguish an isolated defect from a broader issue.
Important limitation: A building inspection is not a geotechnical, environmental or regulatory study. When observations or records warrant, the report recommends the appropriate professional or additional assessment.
