Adjusting a Jack Post (TelePost)

Jill writes: HI, my mom lives in a house built in 57'.She has a big crack in the wall above the doorway. How do you adjust the telepost to accommodate the settling of the property. Which way do you turn the post to adjust it, how much etc, -------Response I assume that the cracks are right above the central beam, and the telepost or jack post. On the top of the post you will see a threaded shaft that goes up to a flat plate nailed to the beam. This threaded rod runs through a "nut" which connects it to the top of the telepost. Take a large wrench and turn that nut. It is really complicated to tell you which way to turn -- but I will try: If you were to be directly under that nut, you should turn it counter clockwise (some people will say "left"). If you are not sure, measure between the nut and the plate above. To raise the telepost you will want to be sure that this distance gets bigger as you turn the nut. Never raise it more than about 1/4 inch per month, or even slower if you have a very old house with plumbing in the centre. It took a long time to settle, you don't to raise it too fast or you could cause problems.
