The House Detective: by Barry Stone, Certified Home Inspector
Dear Barry: I am concerned about environmental hazards in my home — about lead paint, asbestos ceilings, formaldehyde in treated wood, etc. etc. But I’m not very knowledgeable about these things. I’ve read just enough to be scared to death! Now we are planning to sell our home, built in 1978, and are concerned about what may have to be disclosed to buyers. What do you advise? Kim
Dear Kim: Given the age of your home, formaldehyde in plywood and other wood products is an unwarranted concern. After this many years, formaldehyde will have dissipated from wood laminates and finish materials. If you have installed newer materials, formaldehyde is a possibility, but this is not something a homeowner would be expected to know or disclose. Only an environmental inspector with specialized testing equipment could be expected to provide such information.
Textured ceilings in a 1978 home are likely to contain asbestos, but this type of asbestos containing material is not hazardous if left alone. Asbestos fibers only become airborne when the material is disturbed. If you or your buyers want to have the texture removed, it should be tested first to determine if special handling and disposal are required.
Asbestos can also be found in some vinyl flooring materials and some drywall finishing products. Again, this is only a concern if the material is to be removed, in which case testing would be needed.
The manufacture of lead paint was banned in 1978, but it’s use continued until supplies of the material were used up. Therefore, your home may have some lead paint. However, lead paint is only hazardous if ingested. Its mere presence is not unsafe. On the other hand, if exterior lead paint has been allowed to peel, chips may have contaminated the soil around the building. In that case, professional testing would be needed to determine if disclosure and remediation disclosure are needed.
The potential for asbestos and lead in your home is something you can disclose to buyers, with the understanding that you do not know for sure whether these substances are actually present.
