Asbestos was once a commonly used material in construction due to its excellent insulation, fire-resistant properties, and durability. However, it's now widely recognized as a hazardous substance, particularly when its fibers become airborne and are inhaled. One of the most common residential sources of asbestos is old garages, especially those constructed or refurbished before the 1990s.
This guide explores everything homeowners and property managers need to know about asbestos garage removal, including how to identify it, the risks involved, the legal and safety procedures for removal, and what to expect during the process.
What Is Asbestos?
Asbestos is a group of six naturally occurring minerals composed of fine, durable fibers that are resistant to heat, fire, and many chemicals. These properties made it an attractive component in building materials, particularly between the 1930s and 1980s. However, it was later discovered that asbestos exposure can lead to serious health issues, including:
Asbestosis – scarring of the lungs
Lung cancer
Mesothelioma – a rare and aggressive cancer affecting the lining of the lungs or abdomen
Pleural disease – non-cancerous changes to the lining of the lungs
Because of these risks, asbestos is now banned in many countries, and strict regulations govern its handling and removal.
Why Is Asbestos Found in Garages?
Garages, particularly those built before the late 1990s, often contain asbestos materials due to their structural simplicity and exposure to the elements. Common asbestos-containing materials (ACMs) found in garages include:
Roofing sheets (corrugated or flat) – Often made from asbestos cement
Wall panels and ceiling boards
Soffits and fascias
Floor tiles
Pipe insulation
Garage door linings
These materials are typically safe if intact and undisturbed, but they can become dangerous when they degrade or are damaged during renovations or natural wear and tear.
Identifying Asbestos in a Garage
You cannot tell whether a material contains asbestos simply by looking at it. The only way to be sure is through professional testing. Licensed asbestos surveyors can inspect your garage and take samples for lab analysis. There are two main types of surveys:
Management Survey – Identifies ACMs during normal occupancy
Refurbishment and Demolition Survey – Required before major work or demolition, as it locates all ACMs
Never attempt to break or remove suspected asbestos materials yourself—doing so can release dangerous fibers into the air.
Asbestos Garage Removal Process
1. Assessment and Survey
The first step in asbestos garage removal is conducting a thorough inspection by a certified professional. This includes testing samples and assessing the extent of contamination.
2. Obtaining Necessary Permits
In many regions, removing asbestos requires permits and notification to local environmental or occupational safety authorities. Regulations vary, so it's essential to check with your local government.
3. Hiring a Licensed Contractor
Only licensed asbestos removal contractors should handle this job. They have specialized training and equipment to safely remove and dispose of asbestos materials.
4. Containment and Safety Measures
Before removal begins, the area is sealed off to prevent fiber spread. Workers wear personal protective equipment (PPE), including respirators, disposable suits, gloves, and eye protection.
5. Careful Removal and Disposal
Materials are carefully dismantled and wetted to minimize dust. They are then double-bagged in heavy-duty plastic bags, labeled as hazardous, and taken to approved disposal sites.
6. Decontamination and Clearance
After removal, the site is cleaned using HEPA-filter vacuums. An independent inspector may perform air monitoring to confirm the area is safe.
Legal and Regulatory Considerations
Regulations on asbestos removal differ by country and state. In the UK, for example, the Control of Asbestos Regulations 2012 governs all work involving ACMs. In the U.S., the Environmental Protection Agency (EPA) and Occupational Safety and Health Administration (OSHA) have their own requirements.
It is illegal in many areas to dispose of asbestos waste with general household rubbish. Licensed disposal facilities must be used.
DIY vs. Professional Removal
DIY asbestos removal is strongly discouraged. In some jurisdictions, it's illegal without proper licensing. Even if permitted, handling asbestos without training and equipment puts you and your neighbors at serious health risk.
Professional contractors:
Follow safety protocols
Have insurance and liability coverage
Ensure proper waste disposal
Provide documentation and clearance certificates
Tips for Homeowners
Don’t disturb suspected materials. Avoid drilling, sanding, or breaking them.
Seek professional advice. Always consult licensed asbestos assessors.
Plan ahead. Asbestos removal may require permits and coordination with local authorities.
Protect your family. If removal is planned, relocate children and pets during the process.
Maintain records. Keep all reports and removal documents for future property sales or inspections.
Conclusion
Asbestos garage removal is not just a structural issue—it's a serious health concern that requires expert handling. Whether you're renovating, demolishing, or simply maintaining an older garage, being informed and cautious is essential. Working with licensed professionals ensures the safety of your household and compliance with the law. Don't take risks with asbestos—when in doubt, always consult an expert.
