CWS Fence Installation: The Miami Owner’s Guide
We install, replace, and repair CWS fence systems throughout Miami, with full installations typically running $4,130 – $10,620 depending on footage, hardware condition, and post configuration. If a CWS component has failed on your property, we can often match the existing rail profile and color on the first visit and get the repair scheduled within the week. Most Miami homeowners discover the problem the hard way: a post lean after a storm, a gate that drags, or a section that pops loose when the ground shifts after a heavy rain.
Penhallow Remodeling Miami is an independent service provider. We are not affiliated with CWS, but we work with their fence systems regularly and know how they behave in South Florida’s climate. Trevor Nash has seen enough failed CWS post anchors in Miami to know exactly what happens when salt air and sandy soil meet aluminum hardware that was never meant to sit in standing water.
Which CWS Models This Applies To
CWS fence systems are built around a modular aluminum rail and picket design, and the installation details matter more than model numbers. The key identifier is the rail profile: CWS uses a specific channel size that affects what replacement brackets, post inserts, and gate hinges fit properly. Measure the inside width of the top rail channel where the picket slides in. If you’re within a fraction of an inch, we can match it. If the post is bent or the concrete footing has cracked, that changes the repair from a parts swap to a structural fix.
On the OEM-versus-aftermarket question: for CWS rails and pickets, we recommend OEM or exact-match profiles. Aftermarket pickets often run a slightly different thickness, and in Miami’s wind, a picket that rattles is a picket that eventually fails. For hardware like post caps, brackets, and gate pins, a quality aftermarket equivalent is usually fine and costs less. We carry common CWS-compatible hardware on the truck, which saves a second trip for most Miami repairs.

Signs Your CWS Fence Installation Is Failing
- Post lean within 12 inches of the base. This usually means the concrete footing has cracked or was poured too shallow for Miami’s sandy soil. The post itself is often fine; the footing is the problem.
- Gate drags or won’t latch. Hinge sag on CWS aluminum gates is common after 5 – 7 years, especially on wider gates where the weight slowly pulls the hinge screws outward. Sometimes it’s a bent hinge, sometimes the post has shifted.
- Loose pickets that rattle in the rail. The plastic shims inside the CWS rail channel degrade in direct sun. Once a few pickets loosen, the rest follow. The fix is replacing the shims, not the pickets, unless corrosion has started.
- White chalky corrosion at post bases. Salt air in coastal Miami neighborhoods accelerates aluminum oxidation where posts meet concrete. If caught early, it’s a cleaning and sealing job. If the metal has thinned, the post needs replacement.
- Rail pulling out of the post insert. The internal brackets that hold the rail into the post can crack over time. When one rail pulls free, it overloads the adjacent posts, and that’s how a single failed bracket becomes a three-post job.

AfterReplacement Cost & What’s Included
Full CWS fence installation in Miami runs $4,130 – $10,620. The range breaks down like this: material quality (standard versus heavier-gauge aluminum), linear footage, post condition, and access. A straight 60-foot run with good posts and easy gate access lands on the lower end. A property in Coconut Grove with old concrete, tree roots, or a pool cage to work around lands higher. You’ll get a written price before any work starts, and that’s the number you pay, period.

| Single post replacement (CWS-compatible) | $590 – $1,180 | New post, footing repair, rail re-secure |
| Gate hinge and latch repair | $295 – $825 | Hinge replacement, gate re-hang, latch adjustment |

DIY or Call Us?
You can safely check your posts for wobble, inspect the rail channels for cracked shims, and note where the gate scrapes. What you shouldn’t do is reset a post footing in Miami soil without checking the depth and drainage first. Posts need to be set below the root zone and anchored with enough concrete to resist wind load. Get it wrong and you’ll redo the work in eighteen months. Gate hinges are also deceptive: overtightening the hinge screws on a CWS aluminum post strips the threads, and then you’re replacing the post instead of the hinge. If a section has pulled free, the remaining rails are under load that wasn’t in the original design. Call us at (850) 988-7559 and we’ll give you a number first, then pick up the tools.
FAQs
A properly installed CWS aluminum fence lasts 15 – 20 years in Miami, though coastal homes within a mile of salt water may see post-base corrosion in 10 – 12 years. Footing quality and drainage matter more than the aluminum itself. Call (850) 988-7559 and we’ll assess yours honestly.
Minor bends can sometimes be straightened if the post is sound and the footing is intact, but a post bent at the base or showing corrosion at ground level needs replacement. We repair what can be repaired and tell you when replacement is the cheaper long-term answer. Estimates are free at (850) 988-7559.
Replacing a failed section or post usually takes a half day to a full day on site, depending on footing work and concrete cure time for a new post. We’ll give you a clear arrival window before we start. Call (850) 988-7559 to schedule.
We stock common CWS-compatible post caps, rail brackets, gate hinges, and picket shims on the truck. Specialty CWS rail profiles or custom colors may need to be ordered with a few days of lead time. Call (850) 988-7559 and we can usually tell you same-day whether we have what you need.
If your CWS fence is failing, don’t wait for the next storm to finish the job. Call Penhallow Remodeling Miami at (850) 988-7559 for a free estimate. We’ll write the price down, explain what’s actually wrong, and stand behind the work for a full year. We also install and service branded products from KraftMaid, Cambria, and Silestone for our remodeling projects, so the same standard applies whether it’s a fence repair or a full kitchen.
