Serving Every Part of L’Île-Bizard
L’Île-Bizard is a quieter, greener corner of the island, with housing that ranges from waterfront estates to family homes on big lots. The setting shapes the work.
- Waterfront on the lake & river: estates and cottages along Lac des Deux Montagnes and Rivière des Prairies — full interior demolition ahead of high-end rebuilds, with careful shoreline-adjacent work.
- Established residential streets: single-family detached homes on generous lots — gut-jobs, additions, and garage or pool removal.
- Near the nature park & golf: country-style properties — outbuilding demolition and site preparation.
- Newer family subdivisions: modern detached homes — interior reconfiguration and basement finishing.
Phase 1: Demolition That Respects Your Property
On L’Île-Bizard’s large and often waterfront lots, demolition is as much about the grounds as the house — pools, decks, and outbuildings alongside interior gut-jobs. Our crews handle it all, with room to stage equipment, and extra care near the shoreline, mature trees, and septic systems many properties rely on.
- Interior Demolition: safe removal of walls, flooring, and cabinetry, including load-bearing assessments.
- Structure Removal: garage, shed, deck, pool, and rear-extension demolition.
- Concrete Removal: driveway, walkway, and 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: Renovations That Fit How You Live
L’Île-Bizard renovations range from modernizing an older cottage to opening up a family home — updating kitchens and bathrooms, finishing a basement, or reworking a layout to make the most of a waterfront view.
- Kitchen Remodels: opening and updating older or builder-grade kitchens.
- Bathroom Makeovers: updated fixtures and efficient layouts.
- Basement Finishing: home offices, in-law spaces, and family rooms.

Phase 3: Outdoor Spaces for L’Île-Bizard Lots
With large lots, mature trees, and water close by, L’Île-Bizard properties have real room outdoors. We build outdoor spaces for the climate, with proper grading and drainage to protect foundations, septic fields, and the shoreline.
- Grading & Drainage: managing water across large lots and away from foundations.
- Hardscaping: paver patios, stone paths, and steps.
- Privacy & Structures: cedar fences, decks, and green screens.

Permits in L’Île-Bizard
L’Île-Bizard is part of the City of Montréal’s borough of L’Île-Bizard–Sainte-Geneviève, so demolition and structural renovation permits go through the city. Waterfront properties can also fall under shoreline-protection rules, and projects near the water need extra care. In pre-1980 buildings, asbestos is common and has to be handled properly. We manage the paperwork and the safety side so your project stays compliant. You can start with the City of Montréal’s guide to getting a demolition permit.
Frequently Asked Questions
Do I need a permit to demolish part of my home or an outbuilding in L’Île-Bizard?
In most cases, yes. Interior demolition that affects structure, exterior demolition, and removing structures like detached garages or pools typically require a permit through the City of Montréal’s L’Île-Bizard–Sainte-Geneviève borough. We handle the application as part of the job.
Can you demolish a pool, deck, or outbuilding on a waterfront lot?
Yes — it’s a good fit for L’Île-Bizard’s larger and waterfront properties. We safely take down pools, decks, sheds, and detached garages, take extra care near the shoreline and septic field, and haul everything to authorized disposal.
My L’Île-Bizard home was built before 1980 — should I worry about asbestos?
It’s worth checking. Asbestos was used in pre-1980 homes 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.
