Asbestos in Historic Homes
/A few weeks ago we discussed lead based paint as a possible hazard in old houses. Today I’d like to talk about another possible hazard, asbestos. Much of the info I am sharing today is from Asbestos.com.
First, what is asbestos? According to asbestos.com it’s a “naturally occurring mineral compound of soft and flexible fibers that are resistant to heat, electricity and corrosion.” These properties make it highly useful in insulting and strengthening, but asbestos exposure has also been found to be harmful if inhaled.
Houses that were built before 1980 may have asbestos in them. I’ve attached an image here that shows possible locations of asbestos in home. They can include popcorn ceilings, vinyl tile floors, some roofing types, insulation, HVAC duct insulation, among others.
Most of what I’ve read is that concern comes in when the asbestos materials become damaged and airborne. For example, if you have a popcorn ceiling that you want to take down, if it contains asbestos fibers and you just start scraping it off the ceiling on your own, you could be inhaling those fibers and creating a hazard. The best course of action if you are concerned there is asbestos in a material in your home is to first have it tested for the compound. If it is found to be asbestos, hire a professional to make it safe. I’ve seen abatement contractors go about this a couple of ways.
One way is to seal or encapsulate the asbestos in place. For example, if there is a vinyl floor with asbestos tiles, it may be able to be encapsulated by a new floor on top of it. Another way is to remove it completely. Like if you have old ductwork that is insulated with asbestos tape, removing that old ductwork and replacing it with new, up-to-code ductwork and insulation. Knowing the best way to keep your home safe is best kept to the experts for sure. I highly suggest hiring a licensed contractor to do your testing, advise you on the best course of action, and remediating.
Having asbestos in your old home doesn’t have to be a reason to not buy your historic home. It is a reason to proceed with caution and to arm yourself with knowledge.
