Frequently Asked Questions

What spacing should I use between fence posts?

Standard post spacing is 6-8 feet for wood fences and 8-10 feet for vinyl fences. Closer spacing (6 feet) provides more stability, especially for tall fences or windy areas. Never exceed 10 feet spacing or the fence will be too weak.

How deep should fence posts be?

Fence posts should be buried at least 1/3 of their total length. For a 6-foot fence, use 9-foot posts buried 3 feet deep. In areas with frost, bury posts below the frost line (typically 2-4 feet depending on your region) to prevent heaving.

How much concrete do I need per post?

Typically, use 1-2 bags of 50-pound fast-setting concrete per post for standard 4x4 posts. For larger 6x6 posts or tall fences, use 2-3 bags per post. The concrete should extend 6 inches above ground level and be sloped away from the post for drainage.

What are common fence installation mistakes?

Common mistakes include: not checking property lines, forgetting to call 811 for utility location, improper post depth, not using concrete, uneven post height, ignoring local codes, and not planning for drainage. Always get necessary permits before starting.
