Floor Bounce

Question: When I bought my house, the VA inspected it, and i also paid for a home warranty inspection (not required). Both gave me the thumbs up. I wish I had crawled under the house myself. I would have noticed that the floor joists were 2x8. Well 2x8s on a 10-foot span doesn’t seem kosher to me. Luckily all the plumbing is run below the joists, and I am planning to sister 2x8s to the existing joists with glue and nails, and this will hopefully take the bounce out of my floor. Suggestions or comments.

Answer: It is not going to be easy to maneuver the new joists into position and on to the sill plates. Remember that the crown must face up and the weight of the current floor is forcing the floor joists to flatten at the crown. Although you said that the plumbing would not be a problem, what about the electrical?

Without seeing the actual positioning of piping this suggestion may not be workable. I would run a double joist perpendicular to the old joists down the middle of the floor, so that the old joists were now supported in the middle as well as the ends. Depending on where you are, you may have to put in a footer, but only at both ends.

Converting A Small Log Outbuilding As A Part-Time Habitat

Question: We have a nice log outbuilding, of a good size for a small cabin. It was built about 30 years ago, and the logs were creosoted way back then, as it was a storage facility. I would love to convert it to something more useful, if possible, as I am not a builder and don't have resources to start a new one. Do you think that this could be interior plastic-sealed, insulated, with drywall on the interior for farm help habitation? It was made so long back that there is no creosote odor emanating from it at all - even in the sticky heat of summer.

Answer: I would be very hesitant about having someone live in a building that has been creosoted, even if it was decades ago.

The International Agency for Research on Cancer (IARC) and the EPA has determined that creosote is most likely a carcinogenic to humans.

Diagnosticians have determined that breathing the vapors of any of the creosotes has caused irritation of the respiratory tract.

It is almost impossible to seal any structure to the point were vapors are not present, just opening a window or door to the outside could cause the vapors to enter the inside.

The fact that you are aware of the potential health hazard makes you liable should someone become ill after being in the building.
