Jerith Home Additions & ADU: The Boca Raton Owner’s Guide
We stock and install Jerith-compatible components for home additions and ADU projects in Boca Raton, with typical installed pricing running $45,000-$130,000 for full additions and $90,000-$220,000 for detached ADU construction. Most Jerith aluminum fencing and railing systems specified for addition perimeters and ADU setbacks can be sourced and scheduled within our standard procurement cycle, with written quotes delivered before any work begins. Owners usually discover an issue when a Jerith gate panel sags at the hinge post, the powder coat chalks prematurely in south Florida sun, or a section specified for an ADU privacy screen arrives with mismatched picket spacing that fails Boca Raton’s site-plan review.
Which Jerith Models This Applies To
Jerith’s residential aluminum lines break into three series relevant to Boca Raton additions and ADUs. The Style 200, 400, and 100 series differ in wall thickness, rail profile, and picket dimension, and ordering the wrong bracket or gate frame means a return trip that delays your Certificate of Occupancy.
To identify your part, check the stamped label on the bottom rail or the inside face of a post cap. The series number appears first, followed by a two-digit height code (48 for 4-foot, 60 for 5-foot, 72 for 6-foot). Jerith’s OEM posts use a proprietary 2-inch square extrusion with a .062-inch wall on the 200 series, .080 on the 400, and .100 on commercial-grade 100 series. Aftermarket equivalents exist from Specrail and Gilpin, but the bracket hole spacing differs by 3/16 inch, enough to make a gate hang crooked if you mix without redrilling. We stock Jerith OEM posts, hinges, and self-closing mechanisms for the 200 and 400 series because those dominate Boca Raton’s residential addition and ADU permits. The 100 series we special-order, with a 10-14 day lead time from Jerith’s Pennsylvania plant.
Signs Your Jerith Home Additions & ADU Is Failing

- Gate drags or won’t latch. The aluminum frame expands in Boca Raton’s heat and humidity, and the Jerith Tru-Close hinge spring fatigues after 8-12 years of daily cycling. What starts as a half-inch sag becomes a latch miss, then frame stress cracks at the weld.
- Powder coat chalks or flakes within five years. Jerith applies a baked polyester finish rated for 3,000 salt-spray hours, but Boca Raton’s coastal air accelerates UV degradation on south-facing sections. Chalking is surface oxidation; flaking means the substrate is compromised and will pit.
- Post leans at the concrete base. Jerith’s standard post is hollow aluminum; if your addition’s grading crew backfilled with shell rock instead of compacted soil, the post acts as a lever every time the gate swings. The post itself isn’t failed, but the footing is, and resetting it requires cutting the rail to free the post.
- Rattle or buzz in wind over 25 mph. Missing or degraded nylon grommets between picket and rail let metal contact metal. Jerith uses a specific .090-inch wall grommet that compresses to lock the picket; generic replacements are too soft and walk out in heat.
- Bracket bolts loosen quarterly. Jerith’s stainless steel carriage bolts mate with a nylon-insert nut designed for one torque cycle. Repeated tightening without replacement strips the insert, and the bolt backs out from thermal cycling. The fix is new hardware, not more torque.

AfterReplacement Cost & What’s Included
For Jerith component work tied to a Boca Raton home addition or ADU, our installed pricing breaks out as follows:
| Scope | Price Range |
|---|---|
| Single gate reset with new Tru-Close hinges | $380-$620 |
| Post extraction and re-pour with OEM Jerith post | $650-$1,100 |
| Section replacement (8-foot panel, 200 series) | $520-$780 |
| Full Jerith perimeter for addition/ADU (typical 150-200 linear feet) | $8,500-$16,000 |
| Complete home addition project (includes Jerith fencing) | $45,000-$130,000 |
| Detached ADU construction (includes Jerith perimeter) | $90,000-$220,000 |
The range reflects footing depth (Boca Raton’s water table means 30-inch minimums in some Mizner Park-adjacent lots), stucco or paver repair from the extraction, and whether the original installer left spare pickets. Every quote is flat and written before work starts, with line-item parts and labor. Under Clause 1 of the Haven Standard, the price you sign is the price you pay; no change proceeds without a signed change order. Our 365-Day Done Right Promise covers the installation, and Jerith’s 20-year limited warranty covers the aluminum against structural failure.
DIY or Call Us?

An owner can safely check bolt torque with a 7/16-inch socket, verify gate swing clearance, and photograph chalking for a warranty claim. Do not attempt to reset a leaning post yourself. The aluminum shell conducts current, and Boca Raton’s sandy soil means buried utilities are rarely as deep as code specifies. A post extraction near a pool bond wire or sprinkler main is a shock or flood risk. Gate spring tension on a 6-foot Jerith panel runs 45-60 foot-pounds; releasing it without a winding bar can fracture the hinge casting. We carry load-tested replacement hardware, and our crews are background-checked and uniformed.

FAQs
Jerith’s baked polyester finish holds 15-20 years in Boca Raton’s inland zones, 10-15 within two miles of the Atlantic due to salt aerosol. The aluminum substrate itself does not rust, but galvanic corrosion at stainless fasteners can pit the post wall after year 12. Call (754) 254-8065 for an exact quote on replacement versus refresh - estimates are free.
Hinge spring fatigue and grommet degradation are repairable with OEM parts. A cracked weld at the gate corner or rail deformation requires full gate replacement; aluminum welding in the field weakens the heat-affected zone and will fail again. We stock replacement gates for 200 and 400 series in 36-inch and 48-inch widths. Call (754) 254-8065 for an exact quote - estimates are free.
A single gate hinge replacement takes 45 minutes; post extraction and re-pour requires two visits over three days for concrete cure. Full section replacement in an active addition or ADU project is scheduled during a phase gap so fencing does not block framers or inspectors. Call (754) 254-8065 to coordinate with your project timeline - estimates are free.
We carry 200 and 400 series hinges, latches, grommets, and carriage bolts. Posts and gate frames are vehicle-stocked in white and black; bronze and green Jerith colors ship from Pennsylvania in 10-14 days. For active addition and ADU projects, we pre-stage full material kits to avoid delay. Call (754) 254-8065 to confirm availability for your model - estimates are free.
