From our Terrebonne headquarters, Excavation Chanthier serves homeowners and businesses throughout an 89km radius covering Greater Montreal, North Shore, South Shore, Laval, and Laurentides regions.
Three key advantages separate professional Montreal excavation contractors from the rest:
Operating since 2011 • RBQ License #5644-4649-01 • $2M Liability Insurance • CNESST Coverage
Every service backed by 14+ years of experience and available across our complete 89km service area. Municipal permits handled completely by our team.
Complete demolition of concrete, vinyl, and fiberglass pools. Our comprehensive service includes feasibility assessment, complete removal, engineered backfill, compaction, and debris transport. Our compact excavation equipment accesses backyards through standard residential gates.
⚠️ Why choose professional pool removal over DIY: Improper pool removal creates long-term property damage, inadequate drainage, and future foundation issues. Our BNQ-certified process ensures proper backfill compaction and drainage protection that DIY approaches cannot achieve.
Permits handled: We manage all demolition permits, municipal inspections, and compliance requirements across Greater Montreal.
Typical project duration: 2-3 days depending on pool size and access.
Perimeter drainage systems with 20-year warranty. We use exclusively BNQ-certified materials, Delta-MS and Valco waterproofing membranes. Specialized expertise in Montreal’s challenging clay soils and freeze-thaw cycle requirements.
🚫 DIY french drain warning: Improper french drain installation leads directly to basement flooding, progressive foundation damage, and repairs costing 3-5x more than professional installation. Professional installation ensures correct slope gradient, proper backfill layering, and long-term performance in Quebec’s harsh climate.
Permits managed: French drain excavation often requires municipal permits – we handle all applications, engineering approvals, inspections, and municipal sign-offs.
Quebec-specific considerations: Frost line depth requirements, clay soil drainage rates, and seasonal installation timing all factor into proper french drain design.
Complete underground plumbing installation and replacement for residential and commercial properties. We handle all municipal permits and inspections – from initial application to final approval across all Greater Montreal municipalities. Fast response times.
Municipal coordination included: Sewer and water main work requires complex permit applications, utility location coordination (Info-Excavation), and multiple inspection stages. We manage the entire bureaucratic process so you don’t spend weeks navigating municipal requirements.
Why professional installation matters: Underground plumbing work involves high-pressure water mains and sewage systems. Improper installation causes property flooding, contamination risks, and municipal fines. Licensed contractors are mandatory for permit approval.
Foundation work, home extensions, basement lowering, and site preparation. Specialized experience with tight Montreal urban properties where access and proximity to neighboring structures require precision excavation techniques.
Services include:
Permits handled: Foundation excavation requires engineering approvals and municipal building permits – we coordinate everything from engineer consultations to final inspections.
Montreal-specific expertise: Clay soil excavation, existing utility protection, and working within Montreal’s typical 25′ x 100′ urban lots.
House, garage, shed, and building demolition services. Post-disaster intervention demolition available. Complete debris removal, site cleanup, and disposal coordination.
⚠️ Safety-first approach: Structure demolition requires proper utility disconnection (electrical, gas, water), asbestos testing and abatement if present, and comprehensive municipal permits. Never attempt DIY demolition on any structure with utility connections – the risks include electrocution, gas explosion, and structural collapse.
Permit management: Demolition permit requirements vary significantly across Greater Montreal municipalities. We handle all submissions, safety inspection coordination, and compliance documentation.
What’s included:
Greater Montreal’s urban density creates unique excavation challenges that most contractors cannot solve. Understanding why equipment matters helps homeowners avoid costly mistakes.
Most residential properties in Greater Montreal have:
The reality: Standard excavation equipment physically cannot reach most Montreal residential backyards.
We invested specifically in solving Montreal’s unique access challenges:
Real scenarios from our 14 years serving Greater Montreal:
DIY excavation equipment warning: Renting standard-size excavation equipment for Montreal residential properties typically results in three problems:
Compact excavation equipment requires specialized operator training. The tight quarters, precision requirements, and equipment capabilities differ completely from standard excavation.
If your neighbor successfully completed excavation work, we can reach your property too.
Montreal’s unique urban and geological challenges require specialized excavation expertise that out-of-region contractors and DIY approaches cannot provide.

|---|---|---|---|
| Montreal | Leda Clay | High plasticity, poor drainage | Specific compaction techniques |

Operating as an excavation contractor across Greater Montreal’s diverse geography requires specialized knowledge that DIY attempts and out-of-region contractors simply cannot match.
This is what separates professional Montreal excavation contractors from the rest:
We handle everything related to municipal permits:
The homeowner reality without professional permit management: Most Greater Montreal homeowners attempting to secure excavation permits themselves spend 3-6 weeks navigating complex municipal bureaucracy, often facing:
You don’t visit City Hall. You don’t fill out complex forms. You don’t chase municipal inspectors. We handle it all completely.
Permit cost transparency: All permit fees are specified separately in your quote for complete transparency. The significant value is our management of the entire process, not just the fees.
14 years of permit experience means we know every Greater Montreal municipal process, every inspector, and every requirement. Projects that take homeowners 6+ weeks to permit, we complete in 1-2 weeks.
