Therma-Tru Fence Installation: The Miami Owner’s Guide
Therma-Tru fence installation in Miami typically runs $4,130 to $10,620, and that’s the installed number with all mounting hardware, gate hardware, and the fence panels themselves in it. We stock Therma-Tru-compatible fence systems on our trucks and can usually get your install scheduled within the week. Most Miami homeowners call us after a post works loose in sandy soil, a gate starts dragging across pavers, or a storm pushed the fence out of plumb and the latch no longer catches.
Which Therma-Tru Models This Applies To
Therma-Tru’s fence line spans a few distinct series, and not all mounting hardware is interchangeable, which is where we see a lot of DIY frustration in Miami. Here’s what matters when we match parts to your existing setup:
- Post thickness: 3″ square posts take different post caps and brackets than 4″ and 5″ post systems, and mixing them leaves gaps or stress points at the connections.
- Wind load rating: Therma-Tru panels rated for 170 mph need through-bolted brackets to the post, not just face screws. Miami-Dade product approval matters here because a fence that meets it will actually hold in August storms.
- Gate weight class: Single gates under 60 pounds use a standard hinge set. Double driveway gates, which are common in Coconut Grove and Pinecrest, need adjustable hinges with a stronger post footer or the gate sags within a year.
- OEM vs aftermarket: We install OEM Therma-Tru hardware when the fence is still under warranty. Once it’s out of warranty, we often switch to stainless aftermarket brackets rated for salt exposure, because standard steel hardware rusts fast this close to the ocean.
Sawyer Remodel Miami is an independent contractor, not affiliated with Therma-Tru, so we’re free to call it like we see it when an aftermarket part beats the factory part for Miami conditions.

Signs Your Therma-Tru Fence Installation Is Failing
- Posts leaning out from the base. In Miami’s sandy soil, concrete footers that aren’t poured wide enough let the post move within a couple of years. You’ll see a widening soil crack around the footer.
- Gate dragging or not latching. Hinges stretch under heat and humidity. A gate that scraped nothing in January grabs the concrete by June, and the latch plate sits half an inch out of line.
- Panels rattling in wind. Brackets work loose over time, especially on fences with face-screwed connections. You’ll hear it before you see it.
- Rust streaks from hardware. Coastal air eats zinc-plated fasteners fast. Once you see streaks, the screw shanks are thinning and the heads will snap on removal.
- Bottom rails cracking. Panels will not tolerate standing water from a sprinkler trained at the fence. The bottom rail swells and splits at the post connection.

AfterReplacement Cost & What’s Included
For a full Therma-Tru fence installation in Miami, you’re looking at $4,130 to $10,620 depending on linear footage, post depth, gate count, and whether we’re demoing an old fence. A single gate replacement with new hardware and a poured footer lands around $900 to $1,500 of that total.
Every quote we write includes parts, labor, old fence haul-away, concrete, and hardware. You get a written price before we touch the job, and the number on the invoice is the number you approved. The work carries our 365-Day Done Right Promise: if it’s not done right, we make it right, in writing, on every job. No change orders hiding in the fine print.
The big cost variables in Miami are post depth (sandy soil often needs 36″ footers instead of 24″), hurricane-rated hardware, and whether the finish is stock white or a custom color that takes extra weeks from the supplier.
DIY or Call Us?
Replacing a fence post is not a high-danger job the way a garage spring is, but the failure mode in Miami is usually the footer, not the post. Digging a 36-inch footer in coral rock or muck is a half-day fight with a rented auger that bounces off stone, and if the footer isn’t mixed and set in one pour, the post moves again next storm season. You can check for loose brackets and tighten face screws yourself safely. Once a post is leaning, or a gate is out of square, that’s the point to call (850) 801-8046. We’ve pulled enough fence posts out of Miami dirt to know what’s coming out of the hole before we start digging.
FAQs
Expect 15 to 25 years from Therma-Tru panels in Miami, with hardware replacement at the 7 to 10 year mark from salt corrosion. The panel itself outlasts the brackets at this latitude. Call (850) 801-8046 and we’ll walk your fence before you spend on parts you don’t need.
Yes, if the post footers are still solid and the panels are structurally intact, we can swap a section, reframe a gate, or replace hardware without touching the rest of the run. Miami’s soil makes us particular about the footers, so we check those first. Call for a free estimate and we’ll tell you what’s actually needed.
Most Miami fence installs finish in 2 to 3 working days, including demo, footers, and cleanup. Custom-color panels extend lead time by a few weeks because of factory ordering. We give you a live arrival time and photo updates before and after, so you’re not wondering who’s at the gate and what they did while you were at work.
Yes, we keep common Therma-Tru brackets, post caps, hinges, and gate hardware on our trucks for Miami service calls. Unusual panel sizes or custom colors are ordered from the supplier and we’ll quote lead time before you commit. Call (850) 801-8046 for availability on your specific setup.
