Do not over-adjust the telepost. Teleposts should never be adjusted by more than small amounts at a time, especially on newer homes. If this is done too quickly or improperly, large cracks may suddenly appear in walls in the home or flooring may become loose or squeaky. A rule of thumb is to do adjustments no more than one half a turn at a time. This slow adjustment will move the teleposts only millimeters, so several adjustments may be required to achieve the desired height.
