Jerith Home Additions & ADU: The West Palm Beach Owner’s Guide
Jerith-compatible components for home additions and ADUs in West Palm Beach typically run $45,000-$130,000 installed, depending on whether we’re matching existing aluminum framework or building out a full accessory dwelling unit from slab to roof. We stock Jerith-compatible extrusions, gate hardware, and panel sections for same-day repair on most Series 200 and Series 400 enclosures, and we carry the full line of matching infill options for seamless integration with new construction. Most West Palm Beach owners first notice trouble when a gate sags on its hinges, a panel gap opens after a storm, or the latch no longer seats flush - signs that the aluminum frame has shifted or the hardware has corroded in the salt air.
Which Jerith Models This Applies To
Jerith’s residential line breaks into three series that matter for West Palm Beach additions and ADUs. The Series 100 uses 1-inch square pickets with a .050 wall thickness, common on pool enclosures and patio covers built before 2015. Series 200 steps up to 1.5-inch square pickets with a .062 wall, the standard for most ADU privacy screens and courtyard walls we see in neighborhoods like El Cid and Flamingo Park. Series 400 uses 1-inch x 1.5-inch rectangular pickets with decorative rings, usually specified for front-facing additions where curb appeal matters.
To identify your series, check the inside face of the gate frame for a stamped code, or measure the picket width with a tape measure - not the overall panel, the individual vertical member. The hinge bracket bolt pattern also differs: Series 100 uses 3/8-inch carriage bolts on 2-inch centers, while Series 200 and 400 use 1/2-inch bolts on 2.5-inch centers. This matters because a Series 200 gate hung on Series 100 hardware will sag within two seasons.
Rowan Construction Group West Palm Beach is an independent service provider, not affiliated with Jerith. We source OEM Jerith components through authorized distributors, and where lead times stretch past ten days, we specify matching aftermarket extrusions from Superior Aluminum or Ultra with equivalent alloy specs - 6063-T6 for structural members, 6005-T5 for rails - so the weld color and corrosion resistance match the original.
Signs Your Jerith Home Additions & ADU Is Failing

- Gate sag or binding. The top hinge bracket has pulled away from the post, or the aluminum post itself has twisted where it meets the concrete footing. In West Palm Beach, this often follows a tropical storm or simply years of the gate’s weight levering against a single bracket.
- Panel gaps or leaning sections. The horizontal rails have pulled from the vertical pickets at the splice joints, usually because the original rivets have corroded or the thermal expansion from daily sun cycles has worked them loose. You’ll see daylight where there shouldn’t be any.
- Latch misalignment or failure to engage. The strike plate no longer meets the latch body flush. This can be as simple as a loose screw, but more often the gate frame has racked out of square - a sign the diagonal bracing has failed or was never installed.
- White powder or pitting on aluminum surfaces. Salt air accelerates galvanic corrosion where dissimilar metals meet: stainless steel screws against aluminum frames, or steel post anchors embedded in concrete without isolation. The metal isn’t failing structurally yet, but the protective anodized layer is compromised.
- Screens torn or pulling from spline grooves. The fiberglass mesh has UV-degraded after five to seven years of Florida sun, or the spline itself has hardened and no longer grips. This is normal wear, but it exposes the interior to mosquitoes and debris - a functional failure even if the frame is sound.

AfterReplacement Cost & What’s Included
| Component / Scope | West Palm Beach Price Range |
|---|---|
| Jerith-compatible gate rebuild (hardware, hinges, latch) | $800-$2,400 |
| Single panel replacement, Series 200 or 400 | $1,200-$3,500 |
| Full section rebuild (post, rails, pickets, screen) | $3,500-$8,500 |
| ADU enclosure extension with Jerith-matched framework | $12,000-$35,000 |
| Complete home addition with integrated Jerith patio/pool enclosure | $45,000-$130,000 |
The range depends on three factors: whether we’re matching existing anodized color (Jerith’s Bronze and Black are standard; White and Green often require custom powder coating), whether the concrete footings are reusable or need re-poured, and whether the project triggers West Palm Beach’s permit threshold - any enclosure over 75 square feet or attached to the primary structure requires plans and inspection. Under Clause 1 of the Haven Standard, your written quote itemizes each of these before work starts. The 365-Day Done Right Promise covers both parts and labor, and every visit includes a documented photo record of the existing condition, the repair process, and the finished state.
DIY or Call Us?

There’s a clear line for Jerith aluminum work. An owner can safely tighten hinge bolts with a socket set, replace spline and screen mesh with a spline roller from any hardware store, and touch up minor scratches with matching anodized paint. These are maintenance tasks, not repairs.
Where DIY goes wrong: cutting aluminum extrusions without a miter saw and fine-tooth blade leaves burrs that snag screen and collect moisture. Welding aluminum requires a TIG setup and 4043 filler rod - most homeowners don’t own this, and a steel-wire MIG weld will crack in six months. Post-setting in West Palm Beach’s sandy, high-water-table soil demands proper depth (30 inches minimum for 6-foot panels) and specific concrete mix with sulfate resistance; shallow posts lean, and we’ve replaced dozens of owner-installed jobs that looked straight in March and racked by August.
Also, any Jerith enclosure tied to your home’s roofline or structural wall becomes part of the building envelope under Florida Building Code. Unpermitted work can void your wind mitigation inspection and complicate a future sale. We pull permits as standard, not as an upsell.

FAQs
With proper maintenance, the structural aluminum lasts 25 to 30 years; screen mesh needs replacement every 5 to 7 years, and hardware every 10 to 15 years in the salt air. Call (561) 475-3903 for an exact quote on your specific condition - estimates are free.
Individual pickets can be replaced if the rail extrusion is intact, but once a rail is bent or the splice joint has failed, replacement is more reliable than welding - the heat-affected zone weakens adjacent material. We assess this on-site and show you the photo record before recommending either path. Call (561) 475-3903 to schedule your free estimate.
Most single-component replacements finish in one working day; a full section rebuild takes 2 to 3 days, including permit inspection if required. We don’t quote speed - we quote completion with the documentation to prove it. Call (561) 475-3903 for an exact quote - estimates are free.
We carry Series 200 and 400 hinges, latches, spline, screen mesh, and common rail extrusions for same-day repair. Custom colors or Series 100 components typically arrive within 3 to 5 business days from Jerith’s distributor in Orlando. Call (561) 475-3903 to confirm availability for your specific model - estimates are free.
We also stock and install components from KraftMaid, Cambria, and Silestone across our seven trades, so matching your Jerith enclosure to interior finishes in a full ADU build stays under one written quote and one project record.
Measure twice, document everything, then get out of the way and let the work speak. That’s how we’ve kept projects within a few percent of the agreed price across 4,000-plus jobs since 2007.
