Notebook: Lolly Columns

In Jim Thorpe, Pennsylvania, our house detective discovered metal supports or lolly columns under the first-floor joists. These were a clue that the wooden joists in the house had weakened. But just what is a lolly column anyway? Or a floor joist for that matter?

Floor joists are the floor's underlying framework. To support the floor above, joists must be straight, solid and level. If the joists become damaged or warped, they begin to weaken. The joists rest on a beam usually made of wood or steel. If a joist becomes weak, a lolly column can be used under the beam to help support the joist.

If your floors dip or sag, consider using lolly columns. They come in a variety of sizes and are height adjustable. They're easy to conceal with drywall or paint . However, professional installation is recommended.

Lolly columns, beams and floor joists all work together. If you suspect a structural problem in your house, consult a qualified contractor and get the repairs done right away.
