Good Afternoon:

Our family just moved into a new (new construction) home about two months ago. The builder is very well respected in the Indianapolis area. Overall, we are very pleased with the quality of the home and the service we have received.

However, there is one thing that "annoys" us. The builder used an "open web" joist flooring system. What we have found is that this type of flooring system has a higher level of vibration and "bounce" (deflection) to it than the traditional 2" x 10" solid wood joist system. It is "annoying" because items on tables rattle as you walk past them. You can also tell the floor "bounces" if you are sitting down and someone walks past you. We are not used to this and it's probably more of mind-set than anything else.

Nonetheless, is there anything we can do to minimize the vibration or "bounce"? We have an unfinished basement so I can see the open web joists without a problem. The basement is a partial one, so the rest of the open web joists are in a crawl space (under family room).

Please advise so we can try and do something about this minor "annoyance".

Thank you in advance for your help.

Properly designed, the 'open web' trusses should be as stable as any system. Sounds like two possibilities: 1) inadequate supports/too long of spans; or 2) the subflooring is not properly secured and it is causing the 'bounce'. Another possibility is that the subfloor is made of OSB and got wet during construction and is 'spongy'. Have someone check the trusses from the basement to see if they do have 'bounce/spring'. If so, may have to see about additional supports. If not, it may be the subfloor and may be able to correct with screws thru joists into the subfloor from basement. If OSB is damaged, may have to see the builder.

If the webbing is exposed you can add OSB to the sides of it for added support.
