    2x8 floor joist
    I have a new home and the floor joists are 2X8 and they are sistered and there is a bounce. There is hardwood on the floor when I'm sitting in a chair I can feel my 7 pound dog walk across the floor ( I can feel the vibration) Dosen't feel to strong Any suggestions

    How long is the span? How far apart are the joists? Are there any braces installed between the joists?

    I suggest you contact the local building department since they approved the drawings/plans and inspected your home for compliance with same. You can also obtain a copy of the drawings that were approved for a very nominal fee from the building department. Naturally I suggest you obtain the copy of the exact plans that were approved for your home since if the building inspector missed code compliance on the original plans or did not inspect your home properly once they find out the plans could get lost if you know what I mean. I have seen that happen before.

    2x8 are really not sufficient for floor joists. I think you're in trouble.

Tub drain over floor joist [ 10 Answers ]

I am installing a new tub and wall unit and the new tubs drain lines up right over a floor joist. The old tub drain fit right down the side of the joist. There is about a 1.5" difference between the two tub drains. Any way to get around this without moving a floor joist?

Hi, I have a question about floor joist. I had a contractor cut 2 inches out of the bottom of about 15 2x8 floor joist, to hide the electrical lines, instead of drilling holes through the middle of the joist.

Floor joist sizing, [ 6 Answers ]

I have sistered on 2 x 8's to my existing attic floor. It originally was framed with 2 x 4's and then 2 x 6's were sistered along to them. All the 2 x's are resting on the top plate. It feels sturdy enough to lay subflooring onto, but it is a twenty foot span. Will this be adequate?
