Is asbestos siding dangerous?

The danger comes from inhaling asbestos fibers, which can be released if the siding is damaged, deteriorating, crumbling, or disturbed during remodeling or repairs.

He cleaned out the gutters, tested how they worked and how the downspouts worked with water from the hose, and offered me some good suggestions on issues with the functioning of the gutters. I would hire again for the same service.

Very responsive with energy testing and quick to schedule work. Work was done quickly with excellent work quality. A bit slow on the finance/billing side of things and to schedule the follow up energy testing but overall a good experience.

Percolation Tests FAQs, answered by experts

In the event of suspected or confirmed asbestos contamination on the body, it is imperative to take immediate measures to reduce health risks. To avoid further exposure, carefully remove contaminated clothing and shower thoroughly to remove any asbestos fibers. Seek prompt medical attention, and inform your healthcare professional about your suspected asbestos exposure. Since asbestos-related health issues can take years to surface, regular medical check-ups are advised for anyone with a history of exposure.

Asbestos siding can be dangerous, but it doesn't necessarily pose a health risk if it's in good condition and left undisturbed. The danger comes from inhaling asbestos fibers, which can be released if the siding is damaged, deteriorating, crumbling, or disturbed during remodeling or repairs. Exposure to these airborne fibers can cause serious, life-threatening diseases like asbestosis (lung scarring), mesothelioma (an aggressive cancer), and other lung cancers.

If your asbestos siding is intact, the general recommendation is to leave it alone. However, if it's damaged or you plan to renovate, it's crucial to handle it safely. Due to the significant health risks and the difficulty of containing the fibers, it is not recommended to perform any asbestos work yourself. Instead, you should hire a professional asbestos removal company to inspect, repair, encapsulate, or remove the material. The presence of asbestos can also negatively impact your property's value.

The Environmental Protection Agency (EPA) banned the use of asbestos pipe insulation in certain applications in 1975. It released further bans in 1989 and 2019. While asbestos pipe insulation was common from the 1930s to 1970s, its use fell off after the 1970s due to public concern and the EPA's actions.

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

Clear the area for access and inform the testing team about the building’s history and renovations.
