Planning a Project in Senneville?
Don’t juggle 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 Kind of Senneville Property
Senneville is one of the island’s smallest and greenest municipalities, defined by large lots, mature woodland, and a strong sense of heritage. The setting shapes the work.
- Heritage estate homes: grand older houses on generous grounds — careful, selective demolition that protects historic interiors and detail.
- Waterfront properties: homes along Lac des Deux Montagnes — full interior demolition ahead of high-end rebuilds, with care near the shoreline.
- Large wooded & country lots: detached homes on big, treed lots — room to work, plus outbuilding demolition.
- Coach houses, barns & outbuildings: accessory structures on estate properties — structure demolition and site preparation.
Phase 1: Demolition That Respects Your Property
On Senneville’s large, often heritage and waterfront lots, demolition is as much about the grounds as the house — outbuildings, old structures, and detached buildings alongside interior gut-jobs. Our crews handle it all, protecting mature trees, shorelines, and the septic and well systems many properties rely on.
- Interior Demolition: safe removal of walls, flooring, and cabinetry, including load-bearing assessments in older homes.
- Structure Removal: barn, coach-house, garage, shed, and pool demolition.
- Concrete Removal: driveway, walkway, and slab tear-outs.
We handle proper disposal of all materials — wood, concrete, metal — at authorized recycling facilities. See our full demolition services →
Phase 2: Renovations That Fit How You Live
Senneville renovations are usually about updating a heritage or country home for modern living while respecting its character — opening a dated layout, modernizing kitchens and bathrooms, or finishing a lower level — without losing what makes the property special.
- Kitchen Remodels: updating kitchens in older and estate homes.
- Bathroom Makeovers: updated fixtures with respect for period detail.
- Basement & Lower-Level Finishing: making older spaces livable.

Phase 3: Outdoor Spaces for Senneville Lots
With large wooded and waterfront lots, Senneville properties have real room outdoors. We build outdoor spaces that fit the setting, 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: stone patios, paths, and steps.
- Privacy & Structures: cedar fences, decks, and green screens.

Senneville Permits & the Demolition Committee
Senneville is an independent village, not a Montréal borough, so demolition permits go through the Village of Senneville — and the village’s demolition committee reviews demolition requests, weighing a building’s condition, architectural appearance, and the character of the neighbourhood before authorizing the work. We prepare the application and manage that process so your project stays compliant. You can read about the village’s Demolition Committee.
Frequently Asked Questions
Does my Senneville project have to go through the demolition committee?
Often, yes. The village’s demolition committee reviews demolition requests, considering the building’s condition, architectural appearance, and neighbourhood character before authorizing the work. We confirm what applies to your project and prepare the application.
Can you demolish a barn, coach house, or outbuilding on an estate property?
Yes — it’s a good fit for Senneville’s larger properties. We safely take down barns, coach houses, sheds, and pools, protect the surrounding trees, shoreline, and septic field, and haul everything to authorized disposal.
My Senneville 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.
