Boral Fence Installation: The Miami Owner’s Guide
Boral fence installation in Miami typically runs $4,130 – $10,620 including materials and labor, depending on fence length, terrain, and whether we’re replacing an existing run or starting fresh. If your Boral fence has a failed section, cracked post, or loose rails, we can usually schedule the work within a week. Most Miami homeowners discover the problem after a storm pushes a post out of plumb, or when a gate stops latching because the post holding it has shifted in sandy soil.
We’re Penhallow Remodeling Miami, an independent installer that works with Boral fence products. We’re not affiliated with Boral, and we don’t pretend to be. What we are is a team that has been setting fence posts in Miami’s soil long enough to know that what works in Orlando clay doesn’t always hold in Coral Gables limestone or Kendall’s sandy fill.
Key Takeaways
- Typical Boral fence installation in Miami: $4,130 – $10,620 installed
- We carry Boral-compatible posts, rails, and pickets; odd sizes may take 3 – 5 days to source
- Miami’s humidity and hurricane-season winds punish fence hardware first, not the composite itself
- Written price before we start, and a written 365-day guarantee on the work
Which Boral Models This Applies To
Boral fence lines in the South Florida market break into two main families. First, there’s the Boral TruExterior fence board system, which is a poly-ash composite that resists rot and termite damage far better than wood. Second, there are the Boral post sleeves and rail kits sold under the same TruExterior umbrella, designed to wrap pressure-treated posts and hide the wood entirely. If your fence has a chalky gray composite picket with a slightly rough face, you’re almost certainly looking at TruExterior. Boral’s older vinyl fence products still exist on some Miami homes, but they were never the volume seller here that TruExterior became.
The compatibility gotcha we run into constantly: TruExterior boards are 5/8″ thick, not the 3/4″ or 1″ profile common to cedar and most vinyl. A homeowner with a failed section will sometimes buy off-the-shelf composite pickets at a box store, try to slide them into Boral’s aluminum bottom rail, and find they rattle. The channel is cut for 5/8″. If you’re replacing a few pickets, buy Boral or a 5/8″-matched composite. If the rail itself is failing, replace the rail as a unit rather than patching sections, because the aluminum channel deforms once it’s bent and won’t guide a new picket straight.
For aftermarket parts, we’re cautious. Boral’s poly-ash material is genuinely different from wood-plastic composite (WPC). Most “universal” composite fillers and rails are WPC, which expands more in Miami’s heat and sags sooner. For the structural load-bearing pieces, posts and rails specifically, we use OEM Boral or a poly-ash equivalent that matches the thermal expansion rate. For cosmetic trim, aftermarket is usually fine.
Styles & brands we work with
Signs Your Boral Fence Installation Is Failing
- Post lean after any sustained rain event. Miami’s sandy soil loses bearing capacity when saturated, and a post set in a narrow hole will lean. This isn’t the composite failing; it’s the original hole being too small or the concrete collar being too shallow. We dig 30 – 36″ here, below the wet season water table shelf.
- Gate latch that won’t close without a shove. The post holding the gate has shifted, or the hinges have wallowed out their screw holes in the composite. Composite is dense but it doesn’t hold threads the way wood does. We use through-bolts with backing plates on every Boral gate hinge.
- Warped or wavy picket lines in direct afternoon sun. The west-facing side of a Miami fence endures a brutal heat cycle. WPC aftermarket pickets sag under this. Boral poly-ash resists it better, but if even Boral is waving, the pickets were likely installed without the required expansion gap at the rail seam.
- Chalky white residue and fading on south-facing panels. UV degradation is real here. Boral fades slower than most vinyl, but years of Miami sun will chalk any composite. It’s cosmetic, not structural, and it’s a sign the fence is past mid-life, which for Boral in Miami is about 15 – 20 years.
- Loose, rattling pickets in the bottom rail. The aluminum U-channel at the base collects leaves and soil over time. Sand and organic debris grind against the picket bottom, and eventually the channel widens. Pickets start to chatter in the wind. If it’s one or two, we shim them. If it’s the whole run, the rail is done.

AfterReplacement Cost & What’s Included
For Miami, expect Boral fence installation to run $4,130 – $10,620 for a typical residential run of 50 – 100 linear feet. A short repair, like replacing three pickets and a section of bottom rail, lands on the lower end. A full perimeter with two gates, old fence demolition, and difficult access (think narrow Coconut Grove side yards with mature oak roots) climbs toward the upper end.
Here’s how that range breaks down:
- Vinyl fence installation (comparable scope): $4,130 – $10,620
- Aluminum fence installation (stronger, more expensive material): $4,720 – $11,800
- Small repair (post reset, gate realignment, picket swap): $470 – $2,125, depending on what’s actually failed
Every quote includes demolition and haul-away of the old section, new Boral-compatible materials, concrete and hardware, and cleanup. We give you a written price before any work starts. The number on day one is the number on the invoice. And the work itself carries our 365-Day Done Right Promise: if anything we installed fails inside a year, we come back and fix it at no charge. That’s in writing, with a free return visit included, no service call fee.
DIY or Call Us?
Fence work is one of the safer DIY projects we talk people through, but Boral changes the math. The material is heavier than vinyl and denser than cedar. Running a circular saw through poly-ash produces fine dust you don’t want in your lungs, and an unmasked cut can leave a melted edge if you push too fast. If you’re just popping out a cracked picket and sliding a new one in, that’s a reasonable Saturday job, provided you have the right 5/8″ board and a rubber mallet.
Where Miami homeowners get hurt is the posts. A sagging or leaning post means the hole was undersized from day one, and yours likely is too if the fence is under ten years old. Digging out an old concrete collar in Miami soil is sweaty, miss-the-post-hole-digger work, and hitting a limestone shelf at 20 inches is common. That’s where we’d rather you call us. Trevor Nash has spent enough years pulling old posts out of this ground to know when one will fight. Give you a number first, then pick up the tools.

FAQs
Boral TruExterior fencing typically lasts 15 – 20 years in Miami, with fading and rail wear showing first. The composite itself doesn’t rot or attract termites, which is the point of Boral in a humid coastal market. What shortens that lifespan is poor post setting, so a properly installed fence here can outlast that 20-year mark.
In most cases yes, at least section by section. Cracked pickets, loose rails, reset posts, and gate hardware swaps are all repairable without tearing out the whole fence. We’ll only recommend full replacement when the posts are failing in multiple locations or the rail channels have worn past the point of holding pickets securely. Call (850) 988-7559 for an honest read on which one you’re looking at.
A typical repair or partial replacement takes one day on site. A full perimeter replacement usually runs two to three days from demolition through final gate adjustment. Weather can push a day here or there, but we give you a real arrival window before we start, not a four-hour “sometime” window.
We stock common Boral TruExterior pickets, bottom rails, post sleeves, and gate hardware on our trucks. Odd profiles or line-specific colors may take 3 – 5 days to source from our suppliers. If you call with the measurements and a photo, we can usually tell you same-day whether it’s a truck-stock fix or an order-in.
If you’re ready to get a number, call (850) 988-7559 and ask for a fence estimate. We’ll come out, look at your Boral fence, measure what’s actually there, and hand you a written price. No guesswork, no change orders, no surprises.
