Installing your own fence or railing is very doable — but the projects that go smoothly are the ones that follow the steps in order. Skipping ahead (or skipping the gate measurement, specifically) is where most DIY installs run into trouble. Work through this DIY fence installation checklist in order and you'll avoid the most common mistakes.
Before You Dig
-
Call 811 before you dig. This locates buried utility lines on your property. It's free, it's required, and skipping it is not worth the risk.
-
Check local permit and code requirements. This includes property line setbacks, height restrictions, and pool code requirements if your fence encloses a pool.
-
Confirm your gate opening first. Measure and plan your gate placement before you finalize spacing for the rest of the fence line [link to gate width blog will be added here]— the gate sets the reference point everything else is measured from.
Fencing Layout
-
Mark your fence line with stakes and a string line at each corner and post location.
-
Measure post spacing to match your fence panel length — most runs are spaced on standard center-to-center intervals, so confirm the spec for your specific style before marking hole locations.
-
Double-check gate clearance — allow enough room for gate hardware and gate swing before locking in fence post positions.
Digging and Setting Posts
-
Dig post holes to the recommended depth — typically 30–36 inches, or deeper if your area requires footings below the frost line.
-
Size the hole to your post diameter and fill method. As a general guide: 4-inch posts need roughly a 6-inch hole with a concrete alternative or a 10-inch hole with standard concrete; 5-inch posts need roughly an 8-inch hole or a 12-inch hole, respectively.
-
Set your first post and check it for level and plumb before the concrete sets — this is much harder to fix after the fact.
-
Leave a few inches of clearance between the top of the concrete and ground level.
Assembling the Panel
-
Use a spacer under the bottom rail (a 2x4 works well) to keep the panel level while you assemble pickets and rails.
-
Maintain a minimum 2-inch clearance between the bottom of the fence panel and the ground.
-
Set the second post, then check level and plumb again before backfilling with concrete.
-
In high-wind areas, follow the supplemental reinforcement steps for your fence style — this usually means deeper post depth and additional reinforcement.
Finishing Touches
-
Don't glue post caps in place. A small amount of clear silicone is enough to secure them while still allowing removal later if needed.
-
Walk the full line and confirm every post is plumb, every rail is level, and gate swing is clear of any obstructions before calling the project done.
