Building inspection

Building inspector in
Lachine

From Old Lachine to the lakefront, through Saint-Pierre and Dixie, Lachine is a borough with a distinct profile: industrial heritage along the Canal, prewar duplex and triplex housing, postwar bungalows and split-levels, and recent waterfront condos. Proximity to the St. Lawrence River and the historic canal creates a particular inspection context — drainage, humidity, older materials and industrial heritage all intersect here.

Housing-stock profile

Lachine: a mixed
industrial and residential heritage.

A former independent municipality merged into Montreal in 2002, Lachine retains a distinct identity shaped by the Lachine Canal and the proximity of the St. Lawrence River. The borough combines a prewar urban core (Old Lachine, Saint-Pierre), postwar residential development dominated by 1950-1980 bungalows and split-levels, and recent riverfront condo development plus industrial conversions along the canal. Each building type brings its own particular inspection concerns.

🏛
Prewar duplex and triplex (Old Lachine)
The historic core of Lachine retains centenarian brick duplex and triplex housing, often with flat roofs, stone or unreinforced concrete foundations, galvanized plumbing, and original cast-iron drains. Many have undergone partial renovations of varying quality.
🏠
1950-1980 bungalows and split-levels
The residential core of Lachine is dominated by postwar bungalows and split-levels. Many retain their original electrical installation (legacy panels, 1965-1975 aluminum branch wiring) and 50+ year French drains, sometimes never replaced.
🏙
Waterfront condos and industrial conversions
Recent developments along the river and canal include waterfront condo towers and conversions of former industrial warehouses into lofts. Construction quality varies, and concerns over waterproofing, ventilation, and acoustic insulation deserve careful attention.
Soil, drainage and flood-zone

The river and the canal
set the context.

Lachine is bordered by the St. Lawrence River to the south and the Lachine Canal to the north-east. This double proximity maintains a high water table and exposes some riverfront sectors to spring flooding. The soil also carries an industrial legacy along the canal corridor, where factories, warehouses, and port installations once stood.

High water table (river + canal) — Proximity to the St. Lawrence and the Lachine Canal maintains hydrostatic pressure on foundations, French drains, and underground garages. Visible indicators of chronic basement humidity and deficient drainage are common.
Identified flood zones (2017, 2019 floods) — Certain riverfront sectors were affected by recent river floods, as elsewhere on the Island of Montreal. We document visible traces of past infiltration, water-line marks, and the state of restoration. Official mapping is the responsibility of municipal and provincial authorities.
Industrial heritage along the canal — Former industrial lands along the canal corridor may carry historical soil contamination (hydrocarbons, heavy metals). Residential developments on these lands required decontamination, the execution quality of which is verified case by case via a specialized environmental report.
Centenarian foundations of Old Lachine — The prewar duplex and triplex of the historic core rest on fieldstone or unreinforced concrete foundations, sometimes shared with the neighbouring building. Cracks, displacements, and infiltration should be documented and evaluated by a structural engineer if the indicators warrant it.
Common findings

What we document
in Lachine.

The combination of prewar heritage, postwar stock, and recent construction produces a diversified inspection profile in Lachine.

Basement water infiltration — The high water table and river proximity favour chronic infiltration. Water rings, efflorescence on concrete, and wet traces at the base of walls should be documented. See our dedicated page on water infiltration.
Aging French drains — Many postwar bungalows retain their original French drain (50+ years), often never replaced. See our dedicated page on the French drain for visible indicators and inspection limits.
Galvanized plumbing and cast-iron drains — The prewar duplex/triplex and some pre-1970 bungalows retain their galvanized supply plumbing and main cast-iron drains. See our dedicated page on galvanized plumbing and cast-iron drains.
Flat roofs on urban duplex/triplex — As elsewhere in Montreal, many Lachine duplex and triplex buildings have a flat roof with bituminous membrane, parapets, and flashings to evaluate. See our dedicated page on flat roofs.
Legacy electrical panels and aluminum wiring — Many 1960-1980 bungalows retain a legacy-brand panel (Federal Pioneer Stab-Lok, Commander, Sylvania, FPE) or aluminum branch wiring. See our dedicated page on legacy electrical panels and aluminum wiring.
Mold and deficient ventilation — Chronic humidity from river proximity, combined with sometimes insufficient original ventilation, creates conditions favourable to mold. See our dedicated pages on mold and ventilation and condensation.

Heritage Old Lachine, postwar bungalows in Dixie and Duff Court, loft conversions along the canal, waterfront properties on the lakefront — Lachine combines four eras of construction shaped by the canal and the river. Here's how we adapt our work to each typology.

Pre-purchase inspection in Lachine

Lachine is a particularly diverse borough — at the crossroads of the canal's industrial heritage, the postwar residential neighbourhoods, and the waterfront market. Buyers find: century-old brick duplexes and triplexes in Old Lachine, prewar row houses and duplexes in Saint-Pierre, postwar bungalows and split-levels in Dixie and Duff Court, riverfront condos along Boulevard Saint-Joseph (Bord-du-lac), and industrial-to-loft conversions along the canal corridor. Each typology hides its own risks.

Our pre-purchase inspection in Lachine covers more than 400 points: foundation, structure, roof, electrical, plumbing, ventilation, insulation, windows, cladding and lot. We pay particular attention to the high water table and flood zones along the river (2017/2019 floods), the stone foundations of Old Lachine heritage buildings, aluminum wiring frequent in the 1965-1976 stock, and the variable quality of industrial conversions. Report delivered within 24h*.

Home inspection in Lachine

Single-family homes in Lachine span a wide spectrum. In Old Lachine and Saint-Pierre, heritage homes (1900-1940) show stone or unreinforced concrete foundations, old wood framing, flat parapet roofs, galvanized plumbing and cast-iron drains, old electrical panels. In Dixie, Duff Court and the postwar residential sectors, bungalows and split-levels (1955-1975) show concrete-block foundations sensitive to canal humidity, frequent aluminum wiring, attic vermiculite, end-of-life weeping tile. The lakefront sector adds the flood-zone problem and foundations subject to hydrostatic pressure from the river.

A home inspection in Lachine takes 3 to 4 hours on site and includes a complete walk-through of every accessible level, attic, crawlspace and exterior. For properties in flood zones, we document signs of past exposure and verify sump pumps and backwater valves. Report in 24h*.

Condo inspection in Lachine

Lachine has experienced sustained condo-market growth over the past 15 years, primarily along the canal (conversions of former warehouses and factories into lofts), on the lakefront (waterfront projects facing the river), and along rue Notre-Dame. Industrial conversions present specific challenges: original commercial envelope with poorly-insulated thick brick walls, reconfigured shared mechanical ventilation, curtain-wall windows with variable seal integrity, massive foundations prone to infiltration, and often-insufficient basement waterproofing. New lakefront condos can show typical defects of recent construction: balcony slab shrinkage cracking, window seal failure, poorly tuned ventilation.

Our condo inspection in Lachine covers the unit interior (kitchen, bathrooms, windows, panel, plumbing, ventilation) and the visible common areas. We also recommend reviewing the contingency fund study and the syndicate's minutes. Read what a condo inspection can and cannot reveal.

Plex and multi-unit inspection in Lachine

Lachine has a notable stock of duplexes, triplexes and small apartment buildings, particularly in Old Lachine, Saint-Pierre, and along rue Notre-Dame. These buildings typically date from 1900-1960 and have accumulated a century of partial renovations: mixed plumbing (cast iron + copper + ABS, sometimes residual lead in the oldest stock), patchwork electrical (residual knob-and-tube, fuse panels replaced), eroded masonry and rusted steel lintels, multi-layer parapet roofs, wrought-iron exterior staircases. Buildings with 5+ units fall into the commercial multi-unit category.

A plex and multi-unit inspection in Lachine examines every accessible unit, common areas, structure, roof, all mechanical systems, foundation and exterior. For income properties in potentially flood-prone areas, we also flag insurability concerns and major upcoming capital expenses. Custom quote within 24h.

Commercial inspection in Lachine

Lachine concentrates significant commercial and industrial activity: the canal corridor and its industrial park, the rue Notre-Dame axis, the Saint-Pierre airport sector, former industrial buildings undergoing requalification. Commercial and industrial properties often involve requalified heritage buildings (former factories, warehouses, hangars), flat membrane roofs, rooftop HVAC units, three-phase electrical service, and sometimes structural elements modified by successive requalifications.

A commercial inspection in Lachine covers the structure, envelope, roof, electrical service, mechanical systems (HVAC, plumbing, sprinklers if applicable), accessibility, code-compliance flags, parking and lot. For converted industrial buildings, we pay particular attention to use history (potential soil contamination) and structural modifications. Custom quote.

FAQ

Questions about
Lachine.

Do homes near the Lachine Canal and the river have humidity problems?+
Yes. The proximity of the Lachine Canal and the St. Lawrence River maintains a high water table that puts pressure on foundations, French drains, and underground garages. We document visible indicators of infiltration, chronic humidity, and deficient drainage — detailed evaluation of the French drain or sump-pump system is the responsibility of a licensed plumber or a separate camera inspection.
Is Lachine in a flood zone?+
Certain riverfront sectors of Lachine are identified as flood zones or were affected by the 2017 and 2019 floods, particularly along the river. We document visible traces of past infiltration, water-line marks, drainage-system condition, and the quality of restoration. The official flood-zone mapping is the responsibility of municipal and provincial authorities — we orient toward those resources when relevant.
Are former industrial buildings converted into condos along the canal reliable?+
Conversion quality varies. Former warehouses and factories along the Lachine Canal have massive foundations designed for industrial loads, but their residential adaptation raises issues: thermal insulation of thick brick walls, ventilation, reconfigured plumbing, building-code compliance, and basement waterproofing. We document these points during inspection — detailed evaluation of mechanical systems may require a licensed plumber or electrician.
Do you inspect heritage homes in Old Lachine?+
Yes. Old Lachine has a remarkable heritage stock along rue Notre-Dame and the lakefront, with century-old brick duplexes and triplexes and some pre-1900 heritage homes. Common findings: stone or unreinforced concrete foundations, old wood framing, flat parapet roofs, galvanized plumbing and cast-iron drains, old electrical panels. Formal structural evaluation falls under a structural engineer.
How long does a pre-purchase inspection take in Lachine?+
A pre-purchase inspection in Lachine typically takes 3 to 4 hours on site for a postwar bungalow in Dixie or a heritage home in Old Lachine, slightly less for a condo, and longer for a converted loft or a plex. We cover more than 400 points adapted to the typology and deliver a complete written report within 24h*. For properties in potentially flood-prone areas, time on site can be longer.
How much does a home inspection cost in Lachine? What is the price for prewar duplex and triplex (old lachine)?+
Our rates in Lachine start at $550+tax for a condo and $750+tax for a single-family home. For prewar duplex and triplex (old lachine) typical of Lachine, the inspection covers components specific to the era and construction type. Cost may vary with building complexity: presence of basement water infiltration, aging french drains, or galvanized plumbing and cast-iron drains requires additional verifications included in the inspection fee. The cost of a home inspector, house inspector or property inspector depends on the size and age of the building. Contact us for a precise quote in Lachine.
Are you a licensed and accredited home inspector serving Lachine?+
Yes. Our team is InterNACHI-certified, an IBC Network member, and carries professional liability insurance. For Lachine, this expertise is particularly important due to frequent basement water infiltration and local soil conditions (st. lawrence river). As a certified home inspector, house inspector, property inspector or residential building inspector in Lachine, we meet the most demanding North American standards of practice.
Do you offer pre-purchase / pre-buy home inspections in Lachine?+
Yes. The pre-purchase inspection in Lachine (also called pre-buy inspection, buyer inspection or inspection before buying) is our most requested service. For prewar duplex and triplex (old lachine) typical of Lachine, the pre-purchase inspection systematically documents signs of basement water infiltration and other recurring findings that influence purchase decisions or negotiation. We accommodate tight purchase offer timelines — the inspection clause typically provides 7-10 days to complete the inspection and receive the report. Our complete report is delivered within 24h*.
Condo, condominium and apartment co-ownership inspections — available in Lachine?+
Yes. Our condo inspection in Lachine covers condominiums, divided and undivided co-ownerships, apartment co-ownerships, townhouse co-ownerships and plex conversions. In Lachine, these buildings (waterfront condos and industrial conversions) have their own recurring findings — we inspect the unit as well as visible common areas. We recommend a review of the contingency fund study and maintenance log (mandatory under Quebec Law 16). Service offered throughout Lachine.
Plex and multi-unit inspection in Lachine — do you cover all types?+
Yes. Our plex and multi-unit inspection in Lachine covers duplexes, triplexes, fourplexes, rental properties, multi-family buildings and income properties. In Lachine, prewar duplex and triplex (old lachine) are a significant part of the stock — we inspect each accessible unit as well as common areas (staircases, balconies, roofing, foundation, mechanicals). Buildings of 5 units or more fall under the commercial / multi-unit category requiring an adapted inspection approach. Custom quote within 24h.
