How to Put Up Aluminum Fence: Step-by-Step Instructions

Step 1: Plan Your Fence Layout

Check local building codes and HOA restrictions before starting
Contact your utility companies to mark underground lines
Measure and mark your fence perimeter with stakes and string
Mark post locations (typically 6 feet apart) along the string line

The International Association of Certified Home Inspectors recommends checking property lines carefully to avoid neighbor disputes.

Step 2: Prepare for Installation

Gather all materials and tools before starting
Organize your fence sections, posts, and hardware
Make sure your layout markings are still visible and accurate

Step 3: Dig Post Holes

Dig holes at your marked post locations
Make holes about 3 times the diameter of your posts (usually 8-10 inches wide)
Dig to a depth of 1/3 the post height plus 6 inches for gravel
Add 6 inches of gravel to the bottom of each hole for drainage

This Old House experts note that proper drainage prevents frost heave, which can push posts out of the ground in cold climates.

Step 4: Set Corner and End Posts First

Place your corner and end posts in their holes
Make sure they're centered in the holes
Check that each post is perfectly level using your 4-foot level
Adjust the depth or add gravel as needed to achieve proper height
Brace posts temporarily with stakes and boards

Step 5: Mix and Pour Concrete

This is where your fence really takes shape:

Mix concrete according to package directions
Pour concrete around each post, filling to about 3 inches below ground level
Use your level frequently to ensure posts remain straight
Allow concrete to set according to manufacturer's directions (usually 24-48 hours)

Sakrete, a leading concrete manufacturer, recommends not disturbing posts for at least 24 hours after pouring concrete.

Step 6: Install Fence Panels

Start at a corner or end post
Slide the first panel's horizontal rails into the post brackets
Position the next post at the other end of the panel
Check that the post is level before securing it
Secure with self-tapping screws according to manufacturer's instructions
Repeat for remaining panels

Step 7: Cut Panels to Fit (If Necessary)

Measure the space where a full panel won't fit
Mark your cutting line on the panel
Cut with a hacksaw or metal-cutting saw
File any rough edges smooth
Install as normal

Family Handyman suggests measuring twice and cutting once to avoid costly mistakes with aluminum panels.

Step 8: Install Gates

Assemble the gate according to manufacturer's instructions
Attach hinges to the gate and gate post
Hang the gate on the post
Install the latch hardware
Check that the gate swings freely and latches properly
Adjust hinges if needed

Step 9: Add Finishing Touches

Install post caps on all posts
Check that all screws and brackets are tight
Clean any dirt or marks from your new fence

According to Better Homes & Gardens, post caps not only look nice but also protect posts from water damage.
