Building inspection

Building inspector on the
North Shore

Terrebonne, Blainville, Mascouche, Repentigny — the North Shore has experienced explosive growth since the 2000s. New construction, former farmland, variable soils. We know every municipality and its challenges.

Real estate profile

North Shore: rapid growth,
emerging challenges.

Montreal's North Shore stretches across geologically varied terrain, from the St. Lawrence lowland clay plains to the Laurentian foothills. Soils alternate between heavy marine clay in low-lying areas (Repentigny, south Terrebonne) and sand/gravel in higher zones (Blainville, Rosemère). This geological variability, combined with an unprecedented building boom since 2000, creates a unique inspection profile where century-old farmhouses coexist with brand-new residential developments. If you're selling, understanding what sellers should know before listing can help you prepare.

🏗
Variable and unpredictable soils
North Shore soils range from heavy marine clay in the lowlands to sandy and gravelly deposits toward the Laurentians. This variation creates different foundation behaviours from one municipality to the next, and sometimes from one lot to another.
🏘
Post-2000 construction boom
The North Shore has experienced a building explosion since the early 2000s. The high pace of construction has sometimes led to quality shortcuts: poor lot grading, insufficient insulation, and hasty finishes we identify regularly.
🌾
Converted farmland
Many residential developments were built on former agricultural land. These lots, once drained for farming, often present water management problems once urbanized, causing backups and damp basements.
Common findings

What our inspectors find
on the North Shore.

The North Shore presents a unique mix of problems linked to recent construction and older properties. A thorough pre-purchase inspection is especially important in a market where new builds and aging homes coexist. Here are our most frequent findings.

New construction defects — Lot grading directing water toward foundations, missing sealant joints, poorly installed insulation, insufficient attic ventilation in 2005-2020 builds. Our new construction inspection catches these defects at each phase before they become your responsibility. Read our guide to new build defects on the North Shore
Pyrite in some developmentsPyrite-contaminated backfill used under concrete slabs in certain 1985-1995 projects, causing heaving and cracking. This damage can constitute a hidden defect under Quebec civil law
Basement radon — Naturally occurring radioactive gas in the soil, particularly in areas with bedrock. Some North Shore municipalities show concentrations above recommended thresholds
Drainage and grading problems — Poorly graded lots on former farmland, misdirected gutters, inadequate window wells, undersized sump pumps. Our home inspection evaluates drainage, foundation and all major systems
Basement water infiltration — High water table in lowland areas, poor foundation waterproofing in recent builds, inadequate French drains. Read our guide to humidity, mold and ventilation
Ventilation and humidity — Very airtight new homes but poorly ventilated, poorly maintained HRV units, excessive winter condensation on windows. Learn more about humidity and ventilation concerns in suburban homes
Deficient roofs under warranty — Hastily installed shingles, insufficient attic ventilation causing ice dams, poorly installed flashing. Our thermography inspection reveals heat loss and insulation gaps that contribute to ice damming and energy waste
Old septic systems — Rural homes converted to residential areas with outdated or non-compliant septic systems reaching end of life

Our local approach

An inspection adapted
to the local building type.

Each Greater Montreal area has a different building stock. The goal of the inspection is to document the visible and accessible condition of the building, limitations, signs to monitor and specialist verifications that may be recommended depending on age, property type and available access.

🔍
Inspection adapted to your property
Our approach considers building age, property type and available access at the time of the visit. Limitations are documented in the report.
📋
Clear maintenance priorities
The report ranks findings by priority — items to monitor, to verify, or to plan for — supporting decisions after acquisition.
🤝
Specialist verifications when needed
When a finding is beyond the scope of a visual inspection, we recommend consulting a qualified professional for further review.
