Therma-Tru Fence Installation Nationwide

Therma-Tru Fence Installation: The Fort Lauderdale Owner’s Guide

Therma-Tru fence installation in Fort Lauderdale typically runs $3,500-$9,000 for a complete vinyl system, with most residential jobs quoted and started within a week. We stock Therma-Tru-compatible posts, rails, and gate hardware for same-week installation on standard heights and colors. Most Fort Lauderdale homeowners discover their fence needs attention when posts lean after a tropical downpour, rails sag between spans, or gate hinges seize with salt corrosion - problems that start small and accelerate through our wet season.

Which Therma-Tru Models This Applies To

Therma-Tru fences are organized by series rather than model numbers, and the part you need depends on which line was originally installed. The Classic Vinyl series uses 5-inch square posts with routed rail pockets; Cheyenne and Ranch Rail lines use 4-inch posts with bracket-mounted rails. Check the post cap - Classic caps snap on and hide fasteners, while Cheyenne caps are screw-fastened and slightly domed. The inside of the bottom rail often carries a stamped date code and series abbreviation.

We carry OEM-compatible posts and rails that match Therma-Tru’s wall thickness (0.135-inch for residential, 0.180-inch for commercial) and UV inhibitors. Aftermarket equivalents from Bufftech and CertainTeed meet the same spec at lower cost, though color matching to faded Fort Lauderdale installations can be tricky - we bring samples to the estimate. One compatibility gotcha: Therma-Tru’s pre-2018 Classic line used a slightly different rail profile; the pocket spacing differs by 3/8 inch, enough to make new rails sit crooked in old posts. We measure on site before ordering.

Signs Your Therma-Tru Fence Installation Is Failing

• Posts lean or wobble at the base. In Fort Lauderdale’s sandy loam, posts set without proper gravel drainage or below the 24-inch frost line (our local code minimum) loosen after repeated saturation. The concrete collar cracks, water pools, and the post tilts under gate load or wind pressure.
• Rails bow downward between posts. Vinyl expands significantly in heat; rails cut too tight during installation buckle when temperatures climb past 90 degrees, which in Fort Lauderdale is most afternoons from May through October. The rail pulls from the post pocket or cracks at the stress point.
• Gate drags or won’t latch. Salt air corrodes standard steel hinges and latches within three to four years. Therma-Tru’s stainless hardware upgrade lasts longer, but many original installs used the base-grade hardware to hit a price point.
• Post caps crack or blow off in storms. Caps without internal locking tabs become projectiles in tropical storm winds. Once lost, water enters the hollow post, accelerates UV degradation from the inside, and the post wall becomes brittle.
• Discoloration or chalking on south-facing sections. Florida’s UV index degrades TiO2 UV inhibitors faster than northern climates. Chalky residue when you wipe the rail indicates the protective layer is spent; the vinyl beneath becomes prone to cracking.

Replacement Cost & What’s Included

For Fort Lauderdale properties, Therma-Tru vinyl fence installation ranges from $3,500 for a basic 100-linear-foot perimeter to $9,000 for larger lots with gates and stepped terrain. The spread reflects post count (every 6 or 8 feet), gate hardware grade, and whether we hit coral rock during excavation - not uncommon in the Victoria Park area, where we bring a breaker attachment.

Every quote is a flat written price with line-item breakdown - post count, rail footage, hardware spec, gate count, and excavation allowance. Under Clause 1 of the Haven Standard, that price is locked before work starts; no change proceeds without a signed change order. Our 365-Day Done Right Promise covers installation and hardware. You receive a documented photo record of the completed work, including footing depths and post plumb, before we leave.

DIY or Call Us?

An owner can safely check post movement by grasping and rocking - any play over 1/4 inch indicates footing failure. You can also verify gate hinge bolt tightness with a socket set; loose fasteners accelerate wear. But resetting a post requires excavating to 24 inches minimum, mixing and pouring concrete with proper drainage slope, and holding plumb during cure - a two-person job in Fort Lauderdale heat that most homeowners underestimate.

Gate alignment is where DIY goes wrong: a 1/2-inch latch misalignment compounds into binding and hardware failure within months. We see this regularly on Victoria Park resets where the original installer skipped the diagonal bracing. For a failing post or sagging gate, the labor saved rarely offsets the cost of re-doing it. Call (754) 254-7676 and we’ll scope it, price it in writing, and schedule it - no deposit required to hold the date.
