How to Tell If Your Home Has Asbestos (and What to Do if You Find Some)
Asbestos was commonly used in home construction materials from the 1930s through the 1980s because of its strength and insulating properties. However, asbestos is a dangerous material when its fibers are released into the air and inhaled, leading to serious health conditions like lung cancer and mesothelioma. If you live in an older home, it’s crucial to determine whether asbestos is present and learn how to handle it safely. Here’s a guide to help you recognize asbestos, understand the risks, and know what to do if you discover it in your home.
1. Where Asbestos Might Be Found in Your Home
Asbestos was integrated into many different types of building materials, so it can be found in various parts of a home, especially those constructed before the 1980s. It’s not always easy to identify asbestos-containing materials by sight, but there are some common places where asbestos was frequently used.
Knowing where to look can help you spot potential risks before starting home improvements.
- Roofing materials: Asbestos was often mixed into roofing felt, shingles, and tiles to enhance durability and fire resistance.
- Insulation: Asbestos was commonly used as thermal insulation, particularly in attics, around boilers, and wrapped around hot water pipes.
- Garage and porch boards: Many homes used asbestos-containing cement boards under eaves and on porches for weather resistance.
- Ceiling tiles and textures: Asbestos was added to ceiling tiles and “popcorn” or textured coatings for insulation and soundproofing.
- Flooring: Vinyl tiles and linoleum installed before the 1980s may contain asbestos, including the adhesive used to secure them.
- Wall cladding: Cement-based panels or sidings, particularly in garages or outdoor areas, were often made with asbestos fibers for added strength.
2. Signs That Your Home Might Have Asbestos
Asbestos isn’t visible to the naked eye, and there’s no simple way to tell if a material contains it without testing. However, certain signs can raise suspicions, especially in older homes. If you’re aware of these warning signs, you can avoid disturbing materials that might contain asbestos.
- Home’s age: If your home was built before the 1980s, there is a high likelihood that asbestos-containing materials were used in its construction.
- Condition of materials: Cracked, crumbling, or worn-out insulation, ceiling tiles, or roofing might indicate asbestos, as these were common materials where asbestos was added.
- Unlabeled materials: If there are any materials in your home that lack clear labeling or documentation of their composition, especially in garages, attics, or utility areas, they could contain asbestos.
3. What to Do If You Suspect Asbestos
If you suspect that asbestos might be present in your home, avoid disturbing it. Even if the material looks stable, any cutting, sanding, or drilling could release harmful fibers into the air. Instead, take the following steps to ensure safety.
Step 1: Contact an Asbestos Survey Company
Hiring a professional is the safest way to confirm the presence of asbestos. These companies conduct asbestos surveys with a a thorough inspection, take samples, and have them tested in a lab. They can also give you a detailed report on where asbestos is located in your home.
- Professional inspection: An asbestos survey company will take samples safely, using the proper protective gear, and send them to a certified lab for analysis.
- Comprehensive reporting: After the survey, you’ll receive a full report detailing the type, location, and condition of any asbestos-containing materials, so you can decide how to manage them.
Step 2: Use a DIY Asbestos Testing Kit
For small-scale suspicions, such as a single board or tile, you can use a DIY asbestos testing kit. These kits allow you to collect samples, but it’s important to follow the instructions carefully to avoid exposure.
- Wear PPE (personal protective equipment): Always wear a high-quality mask (such as an N95), gloves, and protective clothing when collecting a sample.
- Double-bag samples: Place the material in two heavy-duty plastic bags to prevent any fibers from escaping during transport.
- Follow the testing process: Send your sample to the lab using the provided shipping instructions, and wait for the results before taking any further action.
4. What to Do If Asbestos Is Found
If testing confirms the presence of asbestos, the next steps depend on the condition of the material and your plans for your home. If the material is in good condition, it may be safer to leave it undisturbed. However, if it’s damaged or needs removal, you’ll need to take more serious action.
Leave Asbestos Undisturbed If It’s in Good Condition
Asbestos that is intact and undamaged typically poses a low risk. You can leave it in place as long as it remains undisturbed, but monitor it over time to ensure it doesn’t deteriorate.
- Avoid renovations: If possible, avoid any renovations or repairs that could disturb the material and release asbestos fibers.
- Regular monitoring: Periodically check the condition of any materials that contain asbestos to ensure they aren’t cracking, crumbling, or showing signs of wear.
Hire a Licensed Asbestos Removal Specialist
If the asbestos-containing materials are damaged or need to be removed due to renovation, hire a professional. Asbestos removal specialists are licensed and trained to handle asbestos safely, reducing the risk of exposure.
- Safe removal and disposal: Licensed professionals use special equipment and containment measures to remove asbestos without releasing fibers into the air.
- Legal disposal: Asbestos must be disposed of in accordance with local regulations, which may require double-bagging and special labeling. Your removal specialist will handle this process.
Seal Any Exposed Asbestos Materials
If immediate removal isn’t possible, sealing the material can be a temporary solution to prevent the release of fibers. Use a specialized asbestos sealant or hire a professional to do the job.
- Encapsulation: A sealant can cover asbestos materials, keeping the fibers from becoming airborne until proper removal can be arranged.
- Safe work areas: Ensure that any area with sealed asbestos is well-marked and off-limits to prevent accidental disturbance.
5. Understanding the Health Risks of Asbestos Exposure
Asbestos exposure is hazardous because the fibers can lodge in your lungs and cause serious long-term health problems. Although the effects may not appear until years after exposure, they can be deadly. It’s important to take asbestos seriously and avoid unnecessary risks.
- Mesothelioma: This aggressive cancer affects the lining of the lungs or abdomen and is primarily caused by asbestos exposure.
- Asbestosis: A lung disease that causes severe scarring and breathing difficulties.
- Lung cancer: Prolonged asbestos exposure can also increase the risk of developing lung cancer, especially for smokers.
6. How to Prevent Future Asbestos-Related Risks
Living in a home with asbestos doesn’t have to be a constant worry, but it’s essential to take the right precautions. Whether you leave asbestos materials undisturbed or arrange for removal, prevention is key to ensuring your home remains a safe environment.
- Schedule an asbestos survey: If your home is older and hasn’t been inspected, it’s worth having a professional asbestos survey company assess the property.
- Seal and monitor asbestos: If you cannot remove the asbestos immediately, sealing it and keeping a close eye on its condition can help prevent exposure.
- Hire professionals for renovations: Any work on a home containing asbestos should be handled by licensed professionals who can safely manage the risks.
Conclusion
If you live in a home built before the 1980s, there’s a good chance asbestos may be present. The best way to protect yourself is to avoid disturbing any materials that could contain asbestos, have them tested by professionals, and, if necessary, hire licensed asbestos removal specialists. With proper precautions and professional assistance, you can keep your home safe from the health risks posed by asbestos.
