Working in Côte-des-Neiges means working around shared party walls, narrow rear lanes, and pre-war triplex framing — DemoPrep covers the teardown, the interior rebuild, and the yard across one of Montréal’s densest, most multicultural boroughs, from the storefronts on Chemin de la Côte-des-Neiges up toward Rue Jean-Brillant and the Université de Montréal. RBQ-licensed (#5826-5448-01) and bilingual, we’re the one point of contact throughout. Call 514-613-8344 for a free quote.
Planning a Project in Côte-des-Neiges?
A renovation inside a Côte-des-Neiges triplex rarely stays contained to one trade. We put the demolition, the interior rebuild, and the yard on a single scope of work, priced at a single site visit rather than spread across three companies and three invoices.
Serving Every Corner of Côte-des-Neiges, One Project at a Time
Côte-des-Neiges sits inside the Côte-des-Neiges–Notre-Dame-de-Grâce borough, rising up the north-west face of Mont Royal and holding some of the most densely packed, most multicultural streets on the island. Most of the housing stock is walk-up apartment blocks and triplexes built between the 1920s and the 1950s, set close together with shared party walls and narrow rear lanes — which changes how we plan almost every job here.
- Chemin de la Côte-des-Neiges corridor: The borough’s commercial spine, with dense walk-up housing stacked above the storefronts and interior work that has to account for the units on either side.
- Near Université de Montréal & Rue Jean-Brillant: Fast tenant turnover and unit-by-unit renovations in the apartment buildings closest to campus.
- Queen Mary Road & around the Oratoire Saint-Joseph: Quieter streets higher on the slope, with older single homes and duplexes mixed in among the institutional buildings.
- The Snowdon sector, toward Décarie: Rows of pre-war duplexes and low-rise apartment blocks where basement conversions are a steady call.
Phase 1: Demolition That Respects Your Property
Most of Côte-des-Neiges went up between the 1920s and the 1950s — party walls shared with the building next door, rear balconies and exterior staircases to work around, and materials worth testing before anyone opens a wall. In a triplex, that also means keeping the units above and below livable while work happens beside them.
- Interior Demolition: Unit strip-outs and gut-jobs, with the shared bearing wall between adjoining units checked before anything comes down.
- Structure Removal: Rear additions, sheds, and old exterior staircases removed without disturbing the building next door.
- Concrete Removal: Ruelle-facing parking pads, small rear patios, and basement-slab tear-outs.
Every load of debris — wood, concrete, metal — is sorted and trucked to a licensed Montréal-area recycling or disposal site. See our full demolition services →
Phase 2: Home Renovations That Match Your Life
Côte-des-Neiges mixes long-time family owners, student renters, and new arrivals to the city, and renovation calls reflect that range — turning a semi-below-grade unit into a legal secondary suite, updating a narrow galley kitchen untouched since the building went up, or refreshing a bathroom still running on its original plumbing.
- Kitchen Remodels: Opening up the narrow, closed-off kitchens standard in the borough’s older walk-ups.
- Bathroom Makeovers: Updated fixtures and layouts in units where the plumbing hasn’t been touched in decades.
- Basement Finishing: Converting a semi-underground unit into a rental-ready suite or extra family space.

Phase 3: Outdoor Spaces That Work Year-Round
Yards in Côte-des-Neiges tend to be small and close to the neighbours on both sides, and the borough’s slope means water doesn’t always drain the way a flatter street would. We build outdoor space sized to what’s actually there, with grading that works with the grade of the hill rather than fighting it.
- Grading & Drainage: Correcting runoff on sloped lots climbing toward Mont Royal.
- Hardscaping: Small-footprint patios and walkways sized to a typical Côte-des-Neiges yard.
- Privacy: Fencing and screening between close-set multi-unit buildings.
Why Choose DemoPrep, Demolition Contractors Côte-des-Neiges
We know Côte-des-Neiges’ housing — triplexes and walk-ups sharing a party wall, semi-below-grade units, older buildings near the Oratoire that come with heritage-adjacent restrictions. That knowledge means we test before touching an old wall, work around tenants in occupied units, and file the borough’s paperwork without slowing your project.
- RBQ licence #5826-5448-01, insured for every project we take on
- A crew that moves between English and French easily
- Free quotes with a real number, no pressure to sign
- Job sites kept tidy on a narrow lot, respectful of the building next door
Côte-des-Neiges Permits & Regulations
Because Côte-des-Neiges is a borough of the Ville de Montréal, not its own municipality, demolition and structural renovation permits get filed through Montréal’s arrondissement system rather than a separate town hall. We prepare and submit that file alongside the rest of your project — the City of Montréal’s demolition permit page lists what’s currently required.
Frequently Asked Questions
Does opening up part of a Côte-des-Neiges triplex require a permit?
Usually, yes — it depends on what the work touches. Any interior job that opens a shared bearing wall, or changes the building’s exterior, needs sign-off through Montréal’s arrondissement system first. We assemble and submit that file ourselves, so it isn’t sitting on your desk.
Can you renovate one unit of a Côte-des-Neiges triplex without disturbing the tenants above or below?
Yes — it’s routine work for us in this borough. Dust stays sealed to the work area, noise gets scheduled around whoever’s home, and the goal is simple: nobody living above or below you loses their apartment for the week.
A lot of Côte-des-Neiges was built between the 1920s and the 1950s — should I worry about asbestos?
Fair question. Insulation, floor tile, and joint compound from the 1920s through the 1950s frequently contained asbestos, which lines up with the age of most triplexes and walk-ups in this borough. DemoPrep’s certification spans the full range of abatement work, from a small non-friable patch to a complete friable removal. Nothing here gets demolished until it’s been tested, and where removal turns out to be necessary, the crew works inside HEPA-filtered (99.97%) containment wearing MSA Advantage 3200 full-face respirators with P100 Flexi-Filters, meeting CNESST requirements. A shared wall is worth confirming before it comes down.
If a Côte-des-Neiges project needs demolition, renovation, and the yard redone, is that three contracts or one?
One. The same company manages the demolition, the interior rebuild, and everything left outside, so you’re not juggling three separate invoices for a lot that barely has room for one dumpster.
