There's no splitting or cracking, but the joist is clearly sagging about 1/2" in the middle. It's the end joist, and the floor has settled enough that the quarter round now dips slightly below the baseboard.
I've jacked up and sistered rafters before but am a little unsure how to approach this since the hot water pipe runs directly under the joist preventing me from jacking up the joist directly.
Is it acceptable to lift the joist with a sistered member attached to the half of the joist with the pipe and then fasten it to the other once it comes up to level? If so, how do you gauge an appropriate gap on the new member so that you can jack it up correctly?
Thanks for any advice. We moved some furniture around so that it's visible and it's driving me crazy.
