Formaldehyde in Masonite siding
Q. We bought a 1900-square-foot house in 2007 and, not knowing about formaldehyde in Masonite shingles, immediately had the whole house covered with vinyl siding. Now in 2016 still looks great. However, I have a question. Are we covered well enough that we would have NO problem with formaldehyde? I just only learned about those types of shingles. Now, we want to buy another smaller (retired) house and, lo and behold, it has yellow Masonite shingles!! Thanking you in advance.
A. Any formaldehyde used in the manufacture of siding has long outgassed. You should not have anything to worry about it.by
