James Hardie Fence Installation: The Fort Myers Owner’s Guide

A full James Hardie fence installation in Fort Myers typically runs $3,500 to $9,000, including materials, labor, and debris removal. We stock HardieTrim boards and HardiePlank lap siding in the profiles most fencing applications call for, so once we have your measurements dialed in, the job usually takes two to four days from start to finish. Most owners reach out after watching their wood fence warp, peel, or rot out in the humidity again and start looking for something that actually holds up against Southwest Florida’s wet summers and afternoon thunderstorms. You want a fence that will still be straight and solid five hurricane seasons from now, and that is exactly why James Hardie fiber cement makes sense here.

Which James Hardie Models This Applies To

James Hardie does not manufacture a pre-built fence panel system, so every Hardie fence is a custom assembly built from their exterior trim and siding products. The two product lines we use most in Fort Myers are HardieTrim 5/4 boards for rails and stiles and HardiePlank lap siding for the vertical fence boards. Within HardiePlank, you will usually see Select Cedarmill (wood-grain texture) or Smooth finish specified, both available in 8-1/4-inch exposure widths that work well for standard 6-foot privacy fences. Here is the compatibility detail that catches people off guard: HardieTrim boards come in a 1-inch nominal thickness at 7-1/4-inch width for 5/4 stock, and if your original installer substituted generic cement trim board from a different manufacturer, the fastener schedules and expansion-gap requirements will not match. You can check the stamped lot code on the back face of any leftover material - genuine James Hardie will show a plant code and date, and we can match it. We are an independent contractor, not a factory branch, so we source directly from Hardie distribution partners in Lee County, which means the materials on our truck are exactly what the spec calls for, not whatever was sitting on a shelf.

Signs Your James Hardie Fence Installation Is Failing

Most James Hardie material holds up exceptionally well in Florida’s climate, but the failure points on a Hardie fence are almost always in the installation method, not the product itself. Here is what we see on service calls across Fort Myers:

• Sagging or racked fence sections. The posts were either set at the wrong depth for our sandy soil or the post-footing concrete was backfilled with dirt instead of gravel, letting water pool around the base. In Cape Coral and along the Caloosahatchee, we dig to 36 inches minimum because anything shallower shifts within two rainy seasons.
• Boards pulling loose at nail points. Somebody used electroplated nails instead of hot-dipped galvanized or stainless. Salt air near the coast accelerates corrosion fast, and once the fastener heads snap, the board has nothing holding it to the rail. We only use 316-grade stainless ring-shank fasteners on every Hardie fence we hang.
• Cracking or spalling at board edges. Fiber cement needs a 1/8-inch gap at every butt joint for expansion. If the original installer butted the boards tight, Florida’s humidity cycling will force them to buckle and crack along the edges within a year or two.
• Bottom rails rotting or crumbling. HardieTrim is not rated for direct ground contact. If the bottom rail sits less than 2 inches above grade, capillary action wicks moisture up into the board and it starts to delaminate. We set all bottom rails on a treated kickboard or hold them up on post brackets so they dry out after every rain.
• Mushrooming or staining at fastener heads. This usually means the installer over-drove the nails and broke the factory seal on the board face, giving moisture a direct path into the substrate. Once water gets behind the paint film, the board absorbs it like a sponge and starts to swell around the puncture.

Replacement Cost & What’s Included

A new James Hardie fence installation in Fort Myers falls between $3,500 and $9,000 for a typical residential yard, with the range driven by linear footage, access to the fence line, and whether we are pulling and hauling an old fence at the same time. Smaller side-yard enclosures or pool-code fence runs on the low end come in around $3,500 to $5,000. A full perimeter privacy fence in HardiePlank with custom HardieTrim post wraps and two gates will land closer to $7,000 to $9,000. Every estimate includes the material, pressure-treated posts set in concrete at code depth, stainless fasteners, primer and paint on all cut edges, debris haul-off, and our 730-Day Done Right Promise - if anything shifts or fails due to our workmanship in the first two years, we fix it at no charge. We write line-item quotes with no allowance for “change orders unless you change what you asked for,” so the number you see is the number you pay.

DIY or Call Us?

You can absolutely identify the problem on your own - walk the fence line with a level and look for posts out of plumb, check bottom rails for moisture staining, and eyeball your fastener heads for rust. That will tell you what went wrong and whether the whole fence is headed for replacement or just a couple sections. The actual repair or rebuild is where things get tricky. Hardie fiber cement is heavy - a single 12-foot HardieTrim board weighs over 30 pounds, and trying to hold it square while driving fasteners solo without cracking the board is a two-person job at minimum. More importantly, these boards release respirable crystalline silica when cut, so you need a dust-extraction system and a respirator rated for silica, not a paper mask from the garage shelf. A chop saw throwing silica dust across a Fort Myers backyard on a still afternoon is genuinely dangerous to your lungs and your neighbors’. Most of the fences we replace after a DIY attempt failed started with a homeowner who did the right research but did not have the right tools. Call us at (844) 638-7249 for a free estimate.
