Problems With Cedar Fence Pickets

Non Heartwood Cedar

• When purchasing cedar pickets for fencing, it is essential that you select only cedar heartwood, which is known by its traditional red color. The outer layers, while perfectly usable as lumber, do not seem to share the heartwood's ability to repel pests and resist rot. Quality cedar pickets should be a full 7/8-inch thick, with a rough, almost shaggy face. If in doubt, try the sniff test. True cedar heartwood will have the scent of cedar. Using non heartwood cedar will result in a fence that rots as quickly as cheap white wood pickets.

Splitting

• The surface of cedar pickets can become dry and chalky, leading to a square cracking pattern that is only surface deep. This patterned cracking, known as "checking" does not affect the integrity of the lumber, but does affect the aesthetic value of the more expensive cedar boards. A treatment with a fence conditioner containing linseed or tung oil at the first signs of checking can help to reverse it. Other cracks can result on impact when nailing fence pickets in place. Use treated deck screws to prevent it.

Ground Contact

• Cedar pickets that are not properly spaced above the ground will absorb moisture and rot prematurely. Use an extra picket laid horizontally along the ground to space the pickets up far enough to keep them out of contact with the ground. In situations where the fence requires close contact with the ground, such as a yard with small pets, lay a picket horizontally at ground level and screw it to the face of the fence. This board, known as a kick board, or toe board is easily replaceable if rot sets it.

Cost

• The cost of cedar fencing is typically two times or higher, the cost of treated pine fencing. Treated lumber is rated to last as long, or longer than cedar fencing. The added cost must be weighed against the benefits in aesthetics, which are temporary. Treated lumber and cedar fencing have similar fade rates, as far as the color is concerned, and within six months, untreated, have a similar gray color. Clear oil finishes and stains will help to preserve the color and power washing can help to restore it once faded.
