After we moved in, I noticed that if we closed up the house and were gone for a few hours, when we got back the house smelled like cigarette smoke. The BUILDERS smoked while framing and drywalling.
The stink stuck around for more than a year.
I chose not to stick around a smoking environment for very long, but as long as people smoke in their houses, they have to realize that it takes a toll in either the value of their home or in the costs to clean it.
Boy, I'm surprised it took this long for someone to bring up the fact that construction workers might likely smoke in the new house they are building.
