Boral Fence Installation: The South Florida Owner’s Guide
Boral fence installation in South Florida typically runs $3,500-$9,000 for a complete residential project, and we can usually get your build started within a week of permit approval. We stock Boral-compatible posts, rails, and infill panels for their most common fencing systems, and our crews handle everything from footing to finish. Most homeowners realize they need professional installation when their existing fence starts leaning after a tropical storm, or when they discover the previous contractor used untreated wood posts that rotted at the grade line within three years.
Which Boral Models This Applies To
Boral’s fencing line in South Florida centers on their modular aluminum and composite systems, particularly the Boral TruExterior fence boards and their earlier PermaPorch railing components that were adapted for full fence runs. The critical identifier is the post dimension: Boral aluminum posts measure 2″ × 2″ or 3″ × 3″ with a proprietary bracket system that doesn’t interchange with standard 2″ × 2″ commercial rail. We’ve seen homeowners order generic 2″ × 2″ posts online only to find the Boral rail clips won’t seat properly, leaving a ⅜” gap that voids any wind-load warranty.
We carry both OEM Boral brackets and a heavier-gauge aftermarket equivalent from a Florida fabricator that meets Miami-Dade’s 175 mph wind rating. For the TruExterior poly-ash boards, we stock the 5/8″ × 6″ profile in smooth and wood-grain finishes. If your existing fence was built between 2012 and 2018, check for the Boral stamp on the board underside; earlier PermaPorch components used a different UV stabilizer that we’ve seen chalk significantly faster in South Florida’s UV exposure.
Signs Your Boral Fence Installation Is Failing
- Posts lean or wobble at the base. In South Florida, this usually means the concrete footing cracked from ground saturation during our wet season, or the post wasn’t set below the frost line (irrelevant here, but contractors up north sometimes cut depth). We excavate and pour a 24″ × 24″ footing with rebar cage, not a dry-packed bag mix.
- Rail clips pop loose or boards rattle in wind. Boral’s clip system depends on precise thermal expansion gaps. If the original installer set boards tight in July heat, they’ll buckle by January when temperatures drop to the 50s. We measure ambient temperature at installation and adjust gap spacing accordingly.
- Board surfaces chalk, fade, or develop black streaks. TruExterior’s poly-ash composition resists moisture but still needs periodic cleaning. The black streaks are typically algae colonization from our humidity, not material failure. We can restore most surfaces with a soft wash, though boards with UV degradation past 0.040″ surface depth need replacement.
- Gates sag or latch misaligns seasonally. This points to inadequate diagonal bracing or hinges mounted into composite rather than aluminum framing. Boral gates need a continuous aluminum frame with adjustable hinge plates; we rebuild about six per year where the original builder skipped this.
- Bottom boards swell or delaminate near grade. Even “maintenance-free” materials need proper drainage. In Coral Gables and Pinecrest, we’ve found irrigation systems spraying directly against fence bases accelerates this. We always specify a 2″ minimum clearance and French drain integration where grading holds water.
Replacement Cost & What’s Included
| Component | Price Range (Installed) |
|---|---|
| Full Boral fence installation (per linear foot) | $45-$85 |
| Typical residential project (80-120 linear ft) | $3,500-$9,000 |
| Post replacement (concrete footing included) | $280-$450 each |
| Rail and clip system (per 6-ft section) | $180-$320 |
| Gate rebuild with aluminum frame | $650-$1,400 |
| Board replacement (per 6-ft section) | $95-$175 |
What drives the range: site access (tight lots in Coconut Grove or waterfront properties with coral rock excavation), permit requirements (Miami-Dade requires engineered drawings for fences over 6 feet), and whether we’re matching existing faded material or installing new. Our quotes itemize parts and labor separately. We’re an independent service provider, not affiliated with Boral. We don’t publish warranty terms because they vary by project scope; we’ll document what’s covered in your written proposal.
DIY or Call Us?
There’s a short list of checks any homeowner can handle safely. Verify your property line with a survey (we’ve seen two disputes in Hollywood alone this year). Confirm HOA approval if you’re in a managed community. Check that sprinkler heads won’t spray the fence line directly.
Where DIY goes wrong: post footing depth and mix. South Florida’s sandy soils need 24″ minimum depth with a bell-shaped base to resist uplift in saturated ground. Bag-mix concrete poured dry into a hole and left to absorb groundwater creates a weak, porous footing that fails in the next tropical depression. Stringing a fence line level across 100 feet while accounting for grade changes takes two people and a transit; eyeballing it produces the sags we get called to fix. And if you’re working near buried utilities, Florida law requires an 811 locate - we’ve seen a homeowner puncture a pool line in Boca Raton that cost $4,200 to repair.
Do it right the first time or you’ll do it twice - and the second time always costs more. For a build that survives hurricane season and still looks like it belongs on your street, call (844) 665-0162. Estimates are free, and we’ll walk the property with you.
FAQs
With proper installation, Boral TruExterior fencing lasts 20-25 years in South Florida’s climate, though the aluminum structural components typically outlast the composite boards by 5-8 years. The poly-ash material resists moisture and termites better than wood, but UV exposure will eventually degrade the surface pigment. Call (844) 665-0162 and we’ll assess whether your existing structure has useful life left or needs full replacement.
Partial repair is viable when fewer than 30% of posts are compromised and the rail system remains structurally sound. We replaced 14 boards and three posts for a client in Fort Lauderdale last spring, saving them roughly $6,000 versus full removal. If posts are rotted at grade or the rail clip system is obsolete, replacement is more economical. We’ll give you both numbers when we quote.
A typical 100-linear-foot residential installation takes 3-5 working days after permit approval, assuming standard soil conditions and no coral rock excavation. Permitting in South Florida municipalities runs 2-4 weeks; we handle the submittals and inspections. If you’re on a deadline, call (844) 665-0162 - we can sometimes expedite with preliminary drawings while the full permit processes.
We stock Boral-compatible aluminum posts, rail clips, and TruExterior boards in the most common dimensions on our warehouse truck, and we maintain relationships with regional distributors for specialty orders. For same-week starts, we need to confirm color match against your existing material. Call (844) 665-0162 with your board dimensions or a photo, and we’ll verify stock before we schedule.
