Accepted Answer

Yes. We provide demolition services for office buildings, warehouses, manufacturing facilities, retail stores, schools, healthcare facilities, apartment buildings, condominiums, restaurants, commercial plazas, and residential properties throughout Ontario and Manitoba.

Question 4

What is the difference between selective demolition and full demolition?

Accepted Answer

Selective demolition removes only specific portions of a building while preserving the remaining structure. It is commonly used during commercial renovations, tenant improvements, and building upgrades.
Full demolition involves removing the entire structure and preparing the site for redevelopment or new construction.

Question 5

Is asbestos testing required before demolition begins?

Accepted Answer

Yes. If a building was constructed before the 1990s, asbestos testing should be completed before demolition or renovation work begins. Ontario Regulation 278/05 requires employers to determine whether asbestos-containing materials are present before any work that could disturb them. Early asbestos testing helps prevent project delays, protects workers, and supports regulatory compliance.

Question 6

What permits are required before a demolition project starts?

Accepted Answer

Permit requirements depend on the municipality, building type, and scope of work. Many demolition projects require municipal demolition permits, utility disconnections, environmental assessments, or other approvals before work can begin.
Proper planning helps avoid delays and ensures compliance with local regulations.

Question 7

Can demolition be completed while a business remains operational?

Accepted Answer

Yes. Many selective demolition projects can be completed while businesses remain operational.
Work can often be scheduled during evenings, weekends, shutdown periods, or within isolated work areas to minimize disruption to employees, tenants, customers, and daily operations.

Question 8

How do you coordinate demolition with general contractors and other trades?

Accepted Answer

We work closely with general contractors, project managers, engineers, architects, mechanical contractors, electricians, plumbers, and other trades to integrate demolition into the overall construction schedule.
Proper planning and communication help minimize downtime and keep projects moving efficiently.

Question 9

How does the demolition process work?

Accepted Answer

Most demolition projects begin with a site assessment, permit review, utility disconnection, asbestos evaluation if required, and project planning.
The demolition work is then completed using appropriate equipment and safety procedures, followed by debris removal, recycling where possible, and site preparation for the next phase of construction.

Question 10

What types of structures can you safely demolish?

Accepted Answer

We perform demolition on commercial buildings, industrial facilities, warehouses, retail spaces, offices, healthcare facilities, schools, apartment buildings, residential homes, garages, concrete structures, and interior spaces.
Every project is evaluated individually to determine the safest and most efficient demolition method.

Question 11

How long does a demolition project typically take?

Accepted Answer

Many interior demolition projects can be completed within a few days, while larger commercial and industrial demolition projects may require several weeks depending on the building size, structural complexity, asbestos requirements, and permitting process. Every project schedule is developed to minimize delays and keep construction moving.

Question 12

How do you minimize dust, noise, and disruption during demolition?

Accepted Answer

We use dust suppression methods, containment systems, debris management procedures, and careful project scheduling to reduce disruption. When working in occupied commercial buildings or active construction sites, additional measures are implemented to protect surrounding areas and maintain a safe working environment.

Question 13

Can demolition help reduce renovation costs and project delays?

Accepted Answer

Yes. Proper demolition removes damaged or unnecessary materials efficiently while preparing the site for the next stage of construction. Early planning, asbestos testing, and coordinated demolition work help reduce change orders, unexpected costs, and project delays.

Question 14

How much does demolition cost in Ontario?

Accepted Answer

Demolition costs depend on the size of the structure, building materials, accessibility, asbestos requirements, equipment needed, waste disposal, and project complexity. Smaller interior demolition projects typically range from $3,000 to $15,000, while larger commercial and industrial demolition projects can range from $25,000 to $250,000 or more depending on the scope of work. A site assessment provides the most accurate pricing.

Question 15

How quickly can demolition projects be scheduled?

Accepted Answer

Most demolition projects can be scheduled within a few business days once permits, utility disconnections, and required assessments have been completed.
Emergency and time-sensitive projects may also be accommodated depending on availability.

Question 16

Do you offer emergency demolition services near me?

Accepted Answer

Yes. Emergency demolition services may be available for buildings damaged by fire, storms, structural failures, vehicle impacts, or other unsafe conditions.

Accepted Answer

Question 18

Can I do demolition work by myself?

Accepted Answer

While small, non-structural demolition tasks may seem manageable, most demolition projects involve safety risks, structural considerations, permits, and potential hazards such as asbestos or hidden utilities.
Attempting demolition without proper training, equipment, and regulatory knowledge can lead to injuries, property damage, or costly delays. Hiring a professional demolition contractor helps ensure the work is completed safely, efficiently, and in compliance with local regulations.
