Frequently Asked Questions & Trade Specifications

How many posts and concrete bags do I need for 150 feet of fence?

With 8-foot post spacing and one 4-foot walk gate, you need 20 posts (19 sections + 1 gate latch post). At 2 bags of 50lb fast-setting concrete per post hole, order 40 bags of concrete.

Should I use 2 rails or 3 rails for a 6ft privacy fence?

Always use 3 rails for a 6ft privacy fence. A 2-rail fence will allow 6ft pickets to twist, bow, and cup under summer heat and winter moisture within 18 months.

How deep should fence post holes be dug?

Post holes should be dug to at least 24 inches for a 6-foot fence, or below the local frost line (up to 36-42 inches in northern climates) to prevent winter frost heaving.
