Planning a Project in Saint-Léonard?
Don’t deal with three different companies. We handle the demolition, the renovation, and the landscaping under one roof — and we partner cleanly with your general contractor when a larger build calls for it.
Serving Every Part of Saint-Léonard, One Project at a Time
Saint-Léonard is a plex borough — two-to-five-unit buildings are the rule, single-family homes and condos the exception. That shapes the work we do here. Whether your property is a long-held family triplex near Jean-Talon or one of the newer condo developments going up ahead of the Blue line extension, we know the local housing.
- Jean-Talon & Jarry corridor: Interior gut-jobs and unit modernizations in the older plexes that line the borough’s main streets.
- Lacordaire & Langelier sectors: Garage demolition, rear-yard concrete tear-outs, and basement reconfigurations on the residential streets.
- Saint-Léonard-Sud: Full interior demolition and renovation in the borough’s densest, longest-established residential pocket.
- Newer condo developments: Selective demolition and interior fit-outs in the contemporary builds reshaping the borough.
Phase 1: Demolition That Respects Your Property
Saint-Léonard’s plexes were built solid, but they weren’t built for open-concept living. Our crews handle everything from full interior gut-jobs to exterior tear-downs, working carefully on the borough’s tight residential lots to control dust and noise — and, in multi-unit buildings, to keep the other units livable while we work.
- Interior Demolition: Safe removal of walls, flooring, and cabinetry, including load-bearing assessments in older plex layouts.
- Structure Removal: Garage, shed, and rear-extension demolition.
- Concrete Removal: Driveway, walkway, and basement-slab tear-outs.
We handle proper disposal of all materials — wood, concrete, metal — at authorized Montréal recycling facilities. See our full demolition services →
Phase 2: Home Renovations That Match Your Life
Saint-Léonard has a strong Italian-Canadian community with deep multi-generational roots — many homes have been in the same family for decades. Renovations here are often about reconfiguring space for changing families: opening up a dated kitchen, modernizing a unit, or finishing a basement to give grown kids or aging parents their own space.
- Kitchen Remodels: Opening up the closed galley kitchens common in older plex units.
- Bathroom Makeovers: Updated fixtures and water-efficient layouts.
- Basement Finishing: Creating home offices, in-law spaces, or rental-ready units.

Phase 3: Outdoor Spaces That Work Year-Round
Saint-Léonard is known for its well-maintained homes and abundant parks and green space. We build outdoor areas designed for the Montréal climate, with proper drainage to protect the foundations of the borough’s older buildings.
- Grading & Drainage: Preventing water pooling near foundations.
- Hardscaping: Paver patios, stone paths, and concrete steps.
- Privacy: Cedar fences and green screens for close-set plex lots.

Frequently Asked Questions
Do I need a permit to demolish part of my home in Saint-Léonard?
In most cases, yes. Interior demolition that affects structure, and any exterior demolition, typically requires a permit through the City of Montréal. We handle the application as part of the job so you’re not navigating it alone.
Can you renovate one unit of a plex without disturbing the others?
Yes — it’s a lot of what we do in Saint-Léonard. We contain dust, control noise, and schedule around occupied units so work in one part of a duplex or triplex doesn’t make the rest of the building unlivable.
My home was built before 1980 — should I worry about asbestos?
Possibly — many of Saint-Léonard’s older plexes were built when asbestos was common in insulation, flooring, and drywall compound. DemoPrep is certified and trained for all levels of asbestos removal, from minor non-friable work to high-risk friable abatement. We test before any demolition, and when removal is needed our crews work inside HEPA-filtered (99.97%) containment using MSA Advantage 3200 full-face respirators with P100 Flexi-Filters, following CNESST requirements. It’s not something to disturb without knowing.
Do you handle demolition, renovation, and landscaping together?
Yes. That’s the point of working with us — one team for the demo, the rebuild, and the outdoor work, instead of coordinating three separate contractors yourself.
