The Complete Asbestos Abatement Process Explained

What is asbestos abatement?

Asbestos abatement is the professional process of identifying, containing, removing, and disposing of asbestos-containing materials (ACM) from buildings and structures. Unlike simple demolition or renovation, asbestos abatement requires specialized equipment, certified technicians, and strict regulatory compliance to prevent hazardous fiber release into the air.

The term "abatement" encompasses several activities:

• •Encapsulation: Sealing asbestos materials with specialized coatings to prevent fiber release (used when removal isn't practical)
• •Enclosure: Building permanent barriers around asbestos materials to contain fibers
• •Removal: Complete extraction and disposal of asbestos-containing materials (the most common and permanent solution)

Most residential and commercial projects require complete removal because encapsulation and enclosure only delay the problem. Future renovations or structural changes will eventually require removal anyway, making it more cost-effective to address asbestos permanently when discovered.

When is asbestos abatement necessary?

Professional asbestos abatement becomes necessary when:

• •You're planning renovation or demolition in a building constructed before 1990
• •Laboratory testing confirms the presence of asbestos-containing materials
• •Asbestos materials are damaged, deteriorating, or will be disturbed by construction
• •You're selling a property and buyers require documentation of asbestos removal
• •Local building codes require abatement before issuing permits (common in Calgary, Edmonton, and other Alberta cities)
• •Emergency situations like fire, flood, or structural damage have exposed asbestos materials

In Calgary specifically, the City's Building Services department requires an Asbestos Management Form for any project involving more than 1 square meter of friable asbestos or 10 square meters of non-friable asbestos. This regulatory trigger means most renovation projects eventually require professional abatement services.

Why asbestos abatement matters for health and safety

Asbestos exposure causes serious, often fatal diseases—making professional abatement a critical health protection measure, not just a regulatory checkbox. When asbestos fibers become airborne and are inhaled, they lodge in lung tissue and cannot be expelled by the body's natural defenses.

Health risks of asbestos exposure

The primary diseases linked to asbestos exposure include:

• •Asbestosis: Progressive scarring of lung tissue causing shortness of breath, chronic cough, and reduced lung capacity. No cure exists.
• •Mesothelioma: Aggressive cancer affecting the lining of lungs, abdomen, or heart. Extremely rare outside asbestos exposure.
• •Lung cancer: Asbestos exposure significantly increases lung cancer risk, especially combined with smoking.
• •Pleural diseases: Thickening and calcification of lung lining causing breathing difficulties and chest pain.

These diseases develop slowly—often 10 to 40 years after initial exposure. This latency period means that brief, seemingly minor exposure during DIY demolition can cause disease decades later. There's no safe level of asbestos exposure, and even single fiber inhalation can initiate disease processes.

Who is at risk?

Anyone present during unprofessional asbestos disturbance faces exposure risk:

• •Homeowners and family members: DIY renovation attempts expose everyone in the home, including children who are especially vulnerable
• •Contractors and workers: Unlicensed renovators and their crews face occupational exposure without proper respiratory protection
• •Future occupants: Incomplete removal or improper cleanup leaves residual contamination that continues releasing fibers
• •Neighbors: Airborne fibers can migrate to adjacent properties through ventilation systems or open windows

Professional asbestos abatement using certified containment, HEPA filtration, and clearance testing eliminates these risks. The investment in proper removal protects not just your immediate health, but long-term property value and legal liability.

Professional vs DIY asbestos abatement: Why certification matters

Some homeowners consider tackling asbestos removal themselves to save money. While Alberta regulations technically permit property owners to remove small amounts of asbestos from their own homes, the reality is that DIY asbestos work is dangerous, illegal in many contexts, and ultimately more expensive when considering health risks and compliance failures.

Legal and regulatory considerations

Professional asbestos abatement is required by law in these situations:

• •Commercial properties: Alberta OH&S Code Part 4 mandates certified abatement for all workplace asbestos removal
• •Rental properties: Landlords must hire licensed contractors to protect tenant health
• •Permitted projects: City of Calgary and most municipalities require certified contractors for permitted abatement work
• •Disposal: Only licensed contractors can transport and dispose of asbestos at approved facilities like Shepard Landfill

Even when DIY removal is technically legal, it violates most homeowner insurance policies. Claims for asbestos contamination, exposure lawsuits, or property damage during removal will likely be denied if professional contractors weren't used.

Why professional abatement is safer

Certified asbestos abatement contractors provide safety measures impossible to replicate in DIY projects:

• •Engineered containment systems: Negative-air enclosures with HEPA filtration prevent fiber migration beyond work zones
• •Proper respiratory protection: Full-face respirators with P100 filters or supplied-air systems (not hardware store dust masks)
• •Wet removal methods: Specialized equipment and wetting agents suppress fiber release during material removal
• •Decontamination procedures: Three-stage wash stations prevent workers from carrying fibers outside containment
• •Air monitoring: Real-time fiber measurement ensures containment effectiveness throughout the project
• •Third-party clearance testing: Independent hygienists verify safe fiber levels before re-occupancy

Professional contractors also carry liability insurance protecting you from exposure claims, property damage, and compliance penalties. When you hire Makki Abatement in Calgary, our $5 million insurance coverage transfers financial risk away from your personal assets.

Cost comparison: DIY vs professional removal

While DIY may seem cheaper initially, the true cost calculation includes:

• •Equipment rental: Negative-air machines, HEPA vacuums, and decontamination supplies ($500-$1,500)
• •Protective gear: Tyvek suits, respirators, gloves, goggles for all workers ($200-$500)
• •Disposal fees: Shepard Landfill charges by weight, and DIY haulers often face higher rates ($150-$400)
• •Testing costs: Pre-removal sampling and post-removal clearance testing ($500-$1,500)
• •Lost time: Learning procedures, permit filing, and slower removal pace (often 3-5x longer than professionals)

Most importantly, failed clearance testing requires complete re-cleaning or professional intervention—often costing more than hiring professionals initially. Professional asbestos removal typically costs $1,500-$10,000 for residential projects, but includes permitting, guaranteed clearance, and legal compliance that DIY cannot match.

Step-by-step asbestos abatement process

Professional asbestos abatement follows a systematic process designed to eliminate exposure risk while meeting regulatory requirements. Here's what happens during a typical project:

Step 1: Initial inspection and asbestos testing

Every professional abatement project begins with comprehensive testing to identify asbestos-containing materials and determine removal scope.

What happens during inspection:

• •Certified inspectors visit your property to examine suspect materials including ceilings, floor tiles, insulation, drywall compound, pipe wrap, and siding
• •Bulk samples are collected from each suspect material using specialized tools that minimize fiber release
• •Samples are sent to accredited laboratories for analysis using polarized light microscopy (PLM) or transmission electron microscopy (TEM)
• •Laboratory reports identify material composition, asbestos type (chrysotile, amosite, crocidolite), and concentration percentages
• •Inspectors prepare detailed reports with floor plans showing asbestos locations, photographs, and removal recommendations

In Calgary, laboratory results typically return within 24-48 hours for rush analysis or 3-5 business days for standard turnaround. These reports form the foundation for permit applications and abatement planning. Companies like Makki Abatement offer free inspections when removal services are used, making testing accessible for all property owners.

Step 2: Permit filing and project planning

Once asbestos is confirmed, certified contractors prepare regulatory documentation and design containment systems.

Permit requirements in Calgary:

• •City of Calgary Asbestos Management Form filed through the ePermit portal
• •Laboratory reports and material identification attached to application
• •Detailed scope of work describing containment methods, removal procedures, and disposal plans
• •Alberta OH&S notifications for Type 2 and Type 3 (high-risk) projects
• •Waste transport manifests and Shepard Landfill disposal booking confirmations

Professional contractors handle all paperwork, saving you from navigating complex municipal and provincial requirements. Permit approval typically takes 3-5 business days in Calgary, though rush processing is available for emergency situations.

Step 3: Containment setup and preparation

Before any material is disturbed, certified crews build engineered containment zones to isolate asbestos work areas from occupied spaces.

Containment components include:

• •Polyethylene barriers: 6-mil plastic sheeting seals floors, walls, and ceilings creating airtight work zones
• •Negative-air machines: HEPA-filtered fans create negative pressure, pulling air into containment and preventing fiber escape
• •Decontamination chambers: Three-stage areas for workers to remove protective equipment and shower before exiting
• •HVAC isolation: Ventilation systems are sealed to prevent fiber migration through ductwork
• •Signage and access control: Warning signs and physical barriers prevent unauthorized entry

Alberta regulations define three containment types based on material friability and project scope:

• •Type 1: Low-risk work with minimal fiber release potential (small amounts of non-friable material)
• •Type 2: Moderate-risk work requiring partial containment and respiratory protection
• •Type 3: High-risk work demanding full containment, negative air, and decontamination chambers

Most residential projects require Type 2 or Type 3 containment. Setup typically takes 2-4 hours depending on project size and building configuration.

Step 4: Material removal and waste handling

With containment established, certified technicians begin careful removal using wet methods and specialized equipment.

Removal procedures include:

• •Wet methods: Materials are saturated with amended water or surfactants to suppress dust and fiber release
• •Hand tools: Manual removal using scrapers, pry bars, and cutting tools designed for asbestos work
• •HEPA vacuuming: High-efficiency vacuums capture fibers during removal and cleanup
• •Double-bagging: All waste is placed in 6-mil polyethylene bags, sealed, labeled, and placed in second bags
• •Air monitoring: Real-time fiber measurements verify containment effectiveness throughout removal

Workers wear full protective equipment including respirators with P100 filters or supplied-air systems, disposable Tyvek suits, gloves, and boot covers. All equipment is removed before exiting the decontamination chamber, preventing fiber transport outside containment.

Common materials removed in Calgary projects:

• •Vermiculite attic insulation (common in homes built 1930s-1980s)
• •9×9 and 12×12 vinyl asbestos floor tiles
• •Popcorn ceiling texture and acoustic ceiling tiles
• •Drywall joint compound and textured plaster
• •Pipe and boiler insulation in basements and mechanical rooms
• •Cement board siding and roofing materials

Step 5: Proper disposal and waste transport

Asbestos waste disposal is strictly regulated to protect landfill workers and prevent environmental contamination.

Calgary disposal requirements:

• •All asbestos waste must be transported to the Shepard Landfill asbestos disposal cell (the only approved facility in Calgary)
• •Advance booking required by calling 403-268-2282
• •Transport follows Transport Canada TDG (Transportation of Dangerous Goods) regulations
• •Vehicles must be properly placarded and drivers trained in dangerous goods handling
• •Waste manifests track material from site to final disposal
• •Certified disposal receipts document proper handling for future property transactions

Professional contractors maintain relationships with disposal facilities and handle all scheduling, transport, and documentation. These disposal records become part of your property's permanent documentation, proving compliant asbestos management to future buyers, insurance companies, and regulatory authorities.

Step 6: Air quality testing and clearance

After all material is removed and the work area is thoroughly cleaned, independent third-party hygienists conduct clearance testing to verify safe fiber levels.

Clearance testing procedures:

• •Visual inspection: Hygienists examine all surfaces for visible debris, dust, or residual materials
• •HEPA vacuuming: All surfaces are vacuumed using HEPA-filtered equipment
• •Wet wiping: Surfaces are wiped with damp cloths to capture any remaining fibers
• •Aggressive air sampling: Hygienists use fans and leaf blowers to agitate remaining dust while collecting air samples
• •Laboratory analysis: Air samples are analyzed using phase-contrast microscopy (PCM) or transmission electron microscopy (TEM)
• •Clearance determination: Fiber levels must be below 0.01 fibers per cubic centimeter (f/cc) to meet Alberta occupancy standards

If clearance testing fails, the work area must be re-cleaned and re-tested—at the contractor's expense if the failure resulted from inadequate cleaning. Professional contractors like Makki Abatement have zero failed clearance tests in recent years because proper procedures are followed from the start.

Final documentation includes:

• •Written clearance letters from independent hygienists
• •Laboratory air test results
• •Photographic documentation of completed work
• •Waste disposal receipts and manifests
• •Permit closure confirmation from City of Calgary Building Services

This documentation package protects you legally, satisfies insurance requirements, and provides valuable records for future property transactions. Keep these documents permanently with your property files.

Step 7: Post-abatement reconstruction

Once clearance is confirmed, containment is dismantled and your property is ready for reconstruction. Many professional abatement companies offer integrated services to streamline the transition:

• •Selective demolition: Removal of non-asbestos building components after clearance
• •Site cleanup: Final cleaning and preparation for renovation trades
• •Coordination with contractors: Communication with general contractors, electricians, plumbers, and other trades to maintain project schedules

At Makki Abatement, our selective demolition team can begin work immediately after clearance, eliminating delays and simplifying contractor coordination for Calgary property owners.

What safety measures protect my family during abatement?

Professional asbestos abatement uses multiple safety layers to prevent exposure:

• •Physical containment: Airtight barriers isolate work areas from occupied spaces
• •Negative air pressure: HEPA-filtered fans pull air into containment, preventing fiber migration
• •Occupant relocation: Most contractors recommend occupants vacate during active removal (typically 1-3 days)
• •Adjacent space protection: HVAC systems sealed, doorways protected, and neighboring areas monitored
• •Real-time monitoring: Air sampling during removal verifies containment effectiveness
• •Third-party verification: Independent clearance testing confirms zero contamination before re-occupancy

Many Calgary families choose to stay with relatives or in hotels during active removal, though properly contained projects pose no risk to adjacent rooms. Pets should also be relocated during abatement to prevent stress and accidental containment breaches.

Can I stay in my home during asbestos abatement?

Occupancy during abatement depends on project scope and containment location:

• •Small, isolated projects: You can typically remain in your home if work is contained to a basement, attic, or single room with no shared ventilation
• •Multi-room or HVAC-connected projects: Relocation is recommended for the 1-3 days of active removal
• •Whole-home projects: Complete relocation required until clearance testing confirms safe re-occupancy

Professional contractors will recommend occupancy plans based on your specific project. The cost of temporary housing is minimal compared to the risk of exposure—especially for children, elderly family members, or those with respiratory conditions.
