James Hardie Fence Installation: The Fort Lauderdale Owner’s Guide
James Hardie fence installation in Fort Lauderdale typically costs $3,500 to $9,000 for a full perimeter job, with most mid-sized yards landing around $5,500 to $6,500. We stock HardiePlank and HardieTrim boards, the matching color-matched fasteners, and the aluminum post systems that hold up to South Florida humidity. When your James Hardie fence starts showing separation at the rails, chalky board faces, or rust bleeding from cheap fasteners someone else used, you’re usually looking at a board-level repair or a section rebuild, not a full tear-out.
Most owners discover a problem the same way: a gate starts dragging, a lower board looks swollen at the bottom edge, or a corner post leans after a storm. Fort Lauderdale’s salt air and seasonal downpours work on fence materials year-round, and James Hardie boards need proper clearance, the right fasteners, and sealed cuts or water gets where it shouldn’t.
Which James Hardie Models This Applies To
We work with the two James Hardie product lines commonly used for Fort Lauderdale fencing: HardiePlank lap siding used horizontally as fence boards, and HardiePanel vertical siding for full-panel privacy sections. The 5/16″ (8.25mm) HardiePlank in 8-1/4″ and 12″ exposures are the ones we see most often on residential fences, usually paired with color-matched HardieTrim boards for the rails and corner posts. HardiePanel comes 4×8 and 4×10, and on fence jobs we cut it down to 4×6 or 4×4 panels depending on the post spacing.
The compatibility gotcha most people miss: James Hardie boards are not interchangeable with generic fiber cement from big-box stores. HardiePlank uses a specific edge profile and requires either James Hardie-approved color-matched nails or corrosion-resistant screws. If someone installed yours with electro-galvanized nails from a home center, that’s your failure point. We match your existing board width and texture so a section replacement blends with the rest of the fence. Aftermarket fiber cement equivalents exist, but for fence applications in Fort Lauderdale, the OEM Hardie board with its 30-year limited substrate warranty is what we recommend.
Styles & brands we work with
Signs Your James Hardie Fence Installation Is Failing
- Chalky, faded board faces with visible fiber texture. Fiber cement never rots, but the factory finish erodes under Fort Lauderdale’s UV and salt exposure. Once you see raw fiber at the surface, the board is past a repaint and needs replacement to keep water out.
- Rust streaks running down from fastener heads. Someone used the wrong nails. James Hardie requires hot-dip galvanized or stainless. Electro-galvanized nails rust in two or three seasons near the coast, and the rust stains the board permanently.
- Swollen or soft lower edges within 6 inches of the ground. James Hardie fencing needs minimum ground clearance, usually 2 inches. If the boards were set too low or mulch and soil built up against them, wicking water destroys the bottom edge. Trimming and re-setting is often possible, but the existing boards are usually compromised.
- Gate sagging or dragging with visible rail separation at the hinge side. The gate is the highest-stress point on any fence. When the rail pulls away from the post or the hinge screws strip out of the fiber cement, it’s a structural issue, not a cosmetic one.
- Hairline cracks at fastener holes. Fiber cement holds fasteners well when installed correctly, but overdriven screws or predrilled holes that are too small cause micro-fractures. In Fort Lauderdale’s wet season, those cracks take on water and the board fails from the inside out.

AfterReplacement Cost & What’s Included
In Fort Lauderdale, a single-section James Hardie fence repair with board replacement and fastener swap runs $450 to $1,200 depending on the section size and how much trim work is involved. A full perimeter James Hardie fence installation runs $3,500 to $9,000, with post material (aluminum vs treated pine), gate hardware, height, and linear footage driving the range. A standard 150-foot yard with two gates and aluminum posts usually lands between $5,500 and $7,000.
Every line-item price is in writing before we start. That includes the boards, rails, posts, fasteners, concrete for the post bases, haul-off of the old material, and a written workmanship warranty. No change orders at the door, no “we found something” surprises. You get the number before we pick up a tool, and that’s the number on the invoice.
DIY or Call Us?
A homeowner can safely inspect a James Hardie fence: check ground clearance, look at fastener heads for rust, run a hand along the boards for cracks. What we’d caution against is the actual board replacement. Cutting fiber cement requires a specific blade and produces silica dust you don’t want to breathe. Pre-drilling is mandatory or the boards crack. And gate work is genuinely dangerous, a swinging 80-pound fiber cement gate under tension can break fingers and worse if it comes loose.
If you’re uncertain what you’re looking at, call (754) 354-7423 and describe what you see. We’ll tell you honestly whether it’s a board-level repair or a bigger structural issue, no charge for the conversation.
FAQs
A correctly installed James Hardie fence lasts 20 to 30 years in Fort Lauderdale’s climate, with the factory finish typically needing a repaint every 8 to 12 years and board replacement only at points of mechanical damage or improper installation. If yours failed in under 10 years, it’s almost always a fastener or clearance issue, not the board material itself. Call (754) 354-7423 and we’ll tell you what happened.
Fiber cement boards can’t be structurally repaired once cracked or water-damaged, but cosmetic issues like surface chalk or minor scuffs can be addressed with the proper primer and repaint. If the board is swollen, cracked at fastener points, or separating at the rails, replacement is the only fix that holds up. For an exact diagnosis, call (754) 354-7423 for a free estimate.
A single-section repair with board and fastener replacement is typically done in 4 to 6 hours onsite, while a full perimeter installation takes 3 to 5 working days in Fort Lauderdale depending on linear footage and gate count. We confirm our crew’s arrival time before the workday starts. Call (754) 354-7423 to schedule a look.
