Housing Profile

Family bungalows
and new developments.

Delson's housing stock was built mainly between 1960 and 1990 — single-storey bungalows, story-and-a-half cottages and family semi-detached homes. New residential developments since 2000 add contemporary single-family homes and a few townhouses to the landscape.

🏗
Bungalows and Cottages (1960-1990)
The core of the residential stock: single-storey bungalows, story-and-a-half cottages and semi-detached homes. Concrete-block or poured concrete foundations, frequent aluminum wiring (1965-1975), often original windows.
🧱
Developments 1990-2010
1990-2010 residential developments produced contemporary single-family homes with poured concrete foundations, modernised mechanicals. Common findings: initial settlement, shrinkage cracks, possible pyrite in some sectors.
🔧
Recent Construction (2010+)
New neighbourhoods add modern single-family homes and townhouses. Build quality varying by developer — particular verifications recommended on ventilation, waterproofing and code compliance.
Soil & Foundations

Clay soil
and documented pyrite.

Delson sits on Champlain Sea clay deposits combined with glacial tills — geological characteristic shared with Saint-Constant and neighbouring MRC de Roussillon cities. This composition makes foundations sensitive to differential settlement. Pyrite is also documented in some sectors for 1970-1995 homes.

Clay soil & differential settlement — Sensitive clay shrinks during dry spells and swells when saturated. This behaviour causes foundation cracks and uneven floors. A pre-purchase inspection documents these signs.
Pyrite under basement slab — Documented finding in Delson for 1970-1995 homes. Pyritic backfill swelling causes heaving and cracking of floors. Laboratory test recommended when indicated.
Aging perimeter drainage — Original weeping tiles are reaching end of useful life in 1960-1990 homes. Sediment clogging, deformations are frequent findings.
Chronic basement moisture — Many basements were finished without adequate vapor barrier. Result: moisture and mold behind finished walls.
Common Findings

What we find in
Delson.

Inspections we carry out in Delson reveal a set of findings tied to the varied age of the housing stock (1960-2025) and the geological specifics of the territory — sensitive clay and documented pyrite in some sectors.

Aluminum wiring (1965-1975) — Frequent finding in bungalows and cottages of the era. Overheating risks at connections. Specific verifications (CO/ALR, AluConn) documented.
Documented pyrite — Present in some 1970-1995 sectors. Laboratory test recommended to confirm presence and swelling potential.
Differential settlement & foundation cracks — Clay soil causes seasonal behaviour translating to cracks and shifts. Systematically documented.
Vermiculite & asbestos — Homes built before 1985 often contain vermiculite insulation. Laboratory test recommended before renovation.
Finished basement moisture & mold — Classic combination: saturated weeping tiles, insufficient ventilation, finishing without vapor barrier. Result: chronic moisture and mold development.
End-of-cycle roofs and windows — The 1960-1990 stock is reaching the end of the original renewal cycle. Lifted shingles, broken thermal seals are frequent.
