Is asbestos siding dangerous?

• <div>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.</div>

Great. We did not do a mold test; it was obvious. Mark went ahead with the cleanup procedure. I felt he did a thorough job. The only criticism I had was that it took a couple of calls and a couple of weeks before they came back to pick up the machine they left. It was big and in the way. But,...

You will need a respirator specifically designed to protect against asbestos. However, if you suspect asbestos is present in your home, hire an asbestos abatement professional immediately and avoid the area until they arrive for the inspection.
