At the northeast tip of the island of Montreal, Rivière-des-Prairies–Pointe-aux-Trembles (RDP-PAT) brings together post-war bungalows, waterfront residential areas and the oldest village on the island, founded in 1674. Bordered by the Rivière des Prairies to the north and the St. Lawrence River to the south, the borough faces specific inspection challenges tied to water, soil and the age of its housing stock.
RDP-PAT's housing stock is dominated by bungalows and single-family homes built between 1950 and 1980, the peak of the island's residential expansion. The historic village of Pointe-aux-Trembles, founded in 1674, adds a unique heritage layer, while recent waterfront developments along the river introduce contemporary condos to the picture.
Rivière-des-Prairies–Pointe-aux-Trembles is bordered on two sides by water: the Rivière des Prairies to the north and the St. Lawrence River to the south. This dual river exposure, combined with partially clay soil and several mapped flood zones, creates conditions favourable to infiltration, chronic moisture and mold development in basements.
Inspections we carry out in the borough reveal a consistent set of findings tied to the age of the housing stock (1950-1980 dominant) and the geographic specifics of the territory — dual river exposure, clay soil, flood zones.
We inspect buildings throughout all sectors of the borough, including:
Post-war bungalows, heritage homes in Old Pointe-aux-Trembles, duplexes and triplexes, recent waterfront condos, multiplexes and commercial buildings — RDP-PAT covers a vast and varied housing stock with its own inspection challenges tied to water, soil and the age of the buildings.
RDP-PAT is one of Montreal's largest boroughs and its housing stock reflects that scale: post-war bungalows (1950-1980) dominate, alongside two-storey cottages, semi-detached homes, heritage houses in Old Pointe-aux-Trembles, brick duplexes and triplexes, and recent condo developments along the river. The dual river exposure (Rivière des Prairies to the north, St. Lawrence to the south) and mapped flood zones make pre-purchase inspection particularly important here.
Our pre-purchase inspection in RDP-PAT covers more than 400 points: foundation, structure, roofing, electrical, plumbing, ventilation, insulation, windows, cladding and grounds. We pay particular attention to aluminum wiring (1965-1975), buried oil tank indicators, potentially asbestos-contaminated vermiculite, pyrite under the basement slab, signs of infiltration and mold, and properties in flood zones. Report delivered within 24h*.
Single-family homes dominate RDP-PAT's housing stock: single-storey bungalows 1950-1975, two-storey cottages 1965-1985, semi-detached homes, a few split-levels and a growing number of recent constructions (1995-2025). Old Pointe-aux-Trembles adds a handful of century-old heritage homes. Recurring findings: aluminum wiring, vermiculite, original windows, damp basement.
A home inspection in RDP-PAT takes 3 to 4 hours on site and includes a full visit of every accessible level, the attic, the crawl space and the exterior. We pay particular attention to the foundation, electrical installations (aluminum, grounding), water drainage and signs of moisture in the basement. Report within 24h*.
RDP-PAT has a growing condo stock, especially along the river in Pointe-aux-Trembles (recent projects with water views) and a handful of projects scattered through RDP. Duplex/triplex conversions into co-ownership are also present. Common findings: underground garage drainage, foundation waterproofing in damp zones, unit ventilation, build quality varying by developer.
Our condo inspection in RDP-PAT covers the interior of the unit (kitchen, bathrooms, windows, electrical panel, plumbing, ventilation) as well as the visible common areas. For waterfront projects, we recommend a detailed review of the contingency fund study and the maintenance log. See also what a condo inspection can — and cannot — reveal.
RDP-PAT has a notable stock of duplexes, triplexes and fourplexes, mainly along the central residential arteries of Pointe-aux-Trembles and certain sectors of RDP. Typical construction 1955-1985: concrete-block foundations, copper or galvanized plumbing, electrical with possible aluminum presence, asphalt-shingle or multi-layer roofs, exterior staircases and balconies. Buildings of 5 or more units fall under the commercial / multi-unit category.
A plex and multiplex inspection in RDP-PAT examines each accessible unit, the common areas, structure, roofing, all mechanical systems, foundation and exterior. Custom quote within 24h.
RDP-PAT hosts a varied commercial stock: neighbourhood shops along Boulevard Maurice-Duplessis and Notre-Dame East, shopping centres in Rivière-des-Prairies, scattered office buildings, former industrial buildings (Pointe-aux-Trembles industrial park, petrochemical sectors undergoing conversion) and institutional buildings. Commercial buildings span a wide range of ages (1960-2025).
A commercial inspection in RDP-PAT covers the structure, building envelope, roofing (often flat membrane), electrical service, mechanical systems (HVAC, plumbing, sprinklers if applicable), accessibility, signs of code compliance, parking and grounds. For buildings with industrial history, environmental signals are documented. Custom quote.
