Sellers can be a little confused when they are asked to sign an asbestos disclaimer. Asbestos is a known carcinogen, and when exposed, tiny particles can be released into the air you breathe.
Asbestos is a common insulator used in many homes. It was used for for many other things including siding, tape wrapping for furnace air ducts, and in some "popcorn" ceilings. There are several remedies that range from the simple to the complex.
When you are ready to sell, please give me a call and I can dispel a lot of the myths about asbestos. It's a lot more common than you might think.
