My wife and I have been looking at homes and we walked through 2 modular homes. In one we noticed a definite chemical smell, like an epoxy... some type of glue perhaps and the home was 4 years old. In the other house (2 years old) my wife noticed a different chemical type smell but I didn't think it smelled the same. I'm not sure if it was something that the owners created or not but I understand that some glue is used in the building process. Is this smell something common with modular homes or was it just the 2 homes we looked at?
