Floor joist blocking straps...should they be used?

[Jeffery L. Haynes]

Terry,

I would have written it as well however unless the HI is privy to the blueprints then one can not say as to whether it was part of the original design. Some builders will install bridging (of various types) regardless whether its on the prints or not. As to twisting.....considering the joist are (or should) be tied to the band joists and blocked over girders (we block over girders) then they are not going to twist, especially if they are glued and nailed at the top.

Also, while bridging does help reduce deflection to a small extent, one can not assume they can account for heavier loads.....that is what piers are for.


Ken,

Most the squeaks I had to fix were the result of the subfloor and / or wall bottom plates not being properly nailed (seated); don't ever remember coming across where bridging was part of the problem although I suppose its possible.
I rarely see metal bridging used anymore.... at least not here in the south as much. It was more popular during the 70's and 80's.

I subscribe to the belief that all homes are going to have some squeaks here and there.......... especially considering the number of nails used to frame a home; yet many can be resolved with screws, glue and shims.
