Install Pickets, Decking & Rails: the full procedure

Install the finish surface — fence pickets, deck boards, and railings — straight, evenly spaced, and to the customer's selected style.

• Applies to: Field crew, lead installer
• Frequency: Per job
• Scope: Covers our finish-install standard for consistent gaps, alignment, and appearance. Guardrail height, baluster spacing, and railing load requirements DEFER to local building code & a licensed pro; install to the code-compliant spec on the plan.

What you need

• Drill/impact driver
• Spacing jig/blocks
• Level and chalk line
• Fasteners (per spec)
• Circular or miter saw
• Speed square

The procedure, step by step

1. Confirm frame is complete and inspected — Verify the structural frame is finished, square, and (where required) inspected before installing any finish surface.
2. Set a reference line — Snap a chalk line or set a level reference for the top of pickets or the starter deck board so the whole run stays straight.
3. Use a spacing jig for consistent gaps — Use a spacing jig or blocks for picket gaps and deck-board gaps so spacing is identical across the entire project.
4. Install pickets or decking — Fasten each picket or board to the spec, checking plumb (pickets) or alignment (boards) every few pieces and re-snapping the reference line as needed.
5. Install railings and balusters to spec — Install deck guardrails and balusters per the job plan. Rail height, baluster spacing, and load DEFER to code and a licensed pro — follow the spec.
6. Hang and adjust gates — Hang gates level, set hinges and latch hardware, and confirm smooth swing and proper latching with even reveal.
7. Trim, cap, and finish edges — Install post caps, fascia, stair treads, and trim, cutting clean and consistent lines along the top of the run.
8. Final alignment pass — Sight down the full run and correct any leaning pickets, uneven gaps, or proud fasteners before cleanup.

Quality check before you finish

• Reference line set; run is straight top and bottom
• Picket and deck-board gaps are consistent throughout
• Railings and balusters installed per code-compliant spec
• Gates swing freely, latch securely, with even reveal
• Caps, fascia, and trim installed clean and consistent
• Fasteners flush and to spec — none proud or missed
• Final sight-down pass shows no leaning or uneven pieces
