Floor Joist Underbuilt

Fine circa 1500 chimney stack with rebuilt diagonal shafts.

Floor joist underbuilt.

You can see in the last pic that the field joists are shorter. From what you ve written i dont think your floor is underbuilt but that would depend on the species used for the joists. As you drive in the new screws be sure to stand or kneel on your deckboards to bring them as close as possible to the joists. If you ve got joists that are actually sagging the whole floor might be underbuilt.

Here is where the fun begins. When dealing with a floor joist is it code to replace or can i sister the joists that need repair. West wing is circa 1500 originally jettied and gabled now underbuilt and oversailed. Late c16 inserted first floor with moulded bridging joists and stop chamfered common joists.

I notch the joists the same distance from the underside of the subfloor so the lvl s will carry them evenly and straighten up the floor. Subfloor is all 1 x 6 set on the diagonal. Original hardwood floor in great condition and i have been told the support is underbuilt. 02 25 2011 04 37 pm 23.

And if i do sister does it have to be the whole length of the original joist. I d say if joists are sagged it is underbuilt anyway. The first pic is before the bridging was stapled. I m taking the time to shore up some sagging joists but i m wondering what i can do to fix the squeaky floors in the rooms above.

To the rear of the west wing is a 2 storey late c19 wing in brick part painted. I was at a client s house only to estimate a front door replacement but my eyes were drawn to the second story deck. Doug fir or syp 16 2x10 on 16 should be adequate but just barely. In the end its your house make it the way you like it.

Obviously the floor is severely underbuilt. Screws in addition to securing nails into the joists driving screws into your deckboards is one way to reinforce the strength of your deck.
