Hopefully a straight forward question. I plan on fixing some bounciness on my main level by sistering all of the joists. I shouldn't have much problem getting to all of them and the spans are all fairly short (~2"x6"x10'). Before I glue and nail the sisters all into place, should I bother trying to jack up the existing joists just slightly to relieve pressure, so that the sistered joist immediately goes under pressure as well?
