The house is about 7 years old and the floor in some area have a minor spring to them. The teleposts have never been adjusted but can be easily accessed. Should they be tightened to eliminate the spring and ow often after that?
Its my belief that the teleposts support the beams to in turn support the joists to ensure a level floor, and would have little or no use in adjusting a springy floor, possibly due to heavy point loads in an area from furniture and/or appliances, plus the weight of yourselves.
Closer or deeper joists would have an effect, but in all likelihood your home is built to code.
Some people have a heavy gait to there walk, and bouncy young ones can be a problem too!
Possibly bowed joists with an ill fitting sub-floor? Have a contractor check is best.
As Paul indicated, it wouldn't be the teleposts, nor the beam it supports. It would be in your floor joists. One way to lessen the "bounciness" would be to make sure there are proper bracings or struts in place.
Hope this helps.
