Wellborn Home Additions & ADU: The South Florida Owner’s Guide
Wellborn cabinetry installed in South Florida home additions and ADU projects typically runs $45,000-$130,000 for the full addition build, with cabinet-specific replacement and reconfiguration work ranging $4,000-$13,000 depending on box count and finish. We stock Wellborn-compatible cabinet components, drawer systems, and hardware across the Heritage, Premier, and Estate series, with most replacement parts available same-day from our Miami-Dade warehouse. Most homeowners discover an issue when drawers begin binding after our humid summers, or when coastal salt air degrades hinge finishes in exterior-facing ADU kitchens.
Which Wellborn Models This Applies To
Wellborn organizes its cabinet lines into three tiers, and each uses different box construction and hardware mounting patterns. The Heritage series employs a 3/8-inch furniture board box with standard 35mm cup hinges, while Premier upgrades to 1/2-inch plywood boxes with soft-close undermount slides. Estate series builds on full 3/4-inch plywood with dovetail drawers and Blumotion hardware. To identify your series, check the interior stamp on the hinge side of the door, usually marked “WB-H,” “WB-P,” or “WB-E” followed by a two-digit year code.
Here’s where owners get tripped up: Wellborn changed its drawer slide mounting hole pattern in 2017, so pre-2017 Premier boxes won’t accept current Blum Tandem slides without redrilling the cabinet side. We carry both legacy and current slide patterns. For hardware, the OEM Blum hinges Wellborn specs are excellent, but we also source Salice and Grass equivalents that match the 105-degree opening angle and clip-plate dimensions exactly. Groundwork Construction Co. of South Florida is an independent service provider, not affiliated with Wellborn. You choose the brand, we handle the build, including sourcing factory-matched finishes from Wellborn’s current color library or coordinating with KraftMaid alternatives when a line has been discontinued.
Signs Your Wellborn Home Additions & ADU Is Failing
- Drawers stick or require shoulder-weight to close. In South Florida’s 85%+ summer humidity, particle board drawer boxes absorb moisture and swell against the slide tracks. Heritage series with its 3/8-inch furniture board is most susceptible; we see this in Hialeah and Miami Gardens additions built before 2015.
- Hinge cups loosen and doors sag. The 35mm hinge bore in MDF door stiles can wallow out if the original press-fit wasn’t clean, especially on heavier Estate series raised-panel doors. Once the cup spins, the door drops and catches the frame.
- Finish peels at sink and cooktop cabinets. Wellborn’s standard conversion varnish holds up well, but in ADU kitchens without adequate exhaust, steam and grease break down the film at horizontal surfaces. This isn’t a part failure but a replacement trigger for the affected door and drawer fronts.
- Soft-close mechanism fails and drawers slam. Blum Tandem slides use a hydraulic cylinder that degrades after roughly 80,000 cycles, about 7-8 years in a primary kitchen, shorter in a rental ADU with heavy tenant turnover.
- Corner lazy Susan or pull-out binds. Wellborn’s kidney and full-round Susan hardware uses a telescoping shaft that collects grease and salt residue in coastal South Florida zip codes. The shaft seizes, and owners force it until the polymer hub cracks.
Replacement Cost & What’s Included
For South Florida homeowners, Wellborn cabinet component replacement breaks down as follows:
- Cabinet box replacement (single unit): $800-$2,200
- Drawer box and slide replacement: $180-$420 per drawer
- Door and drawer front replacement (per piece): $140-$380
- Full hinge and hardware refresh (per cabinet): $95-$210
- Pull-out organizer or Susan mechanism: $320-$780
These figures include removal, disposal, new components, and reinstallation with level and plumb check. What drives the range? Finish grade (painted finishes cost more than stained), whether we need to match a discontinued color from archived production runs, and access in tight ADU kitchens where we work around plumbing and electrical. Full addition builds with Wellborn cabinetry run $45,000-$130,000 in the South Florida market, with ADU construction at $90,000-$220,000. We warranty our installation workmanship for two years; manufacturer defects on Wellborn product fall to their standard coverage, which we handle the claim paperwork for.
DIY or Call Us?
There’s honest middle ground here. A homeowner with a Phillips head and patience can swap a Blum hinge or adjust a drawer front using the turn-screws on the clip plate. What goes wrong fast: drilling new hinge cups or slide holes without a 35mm Forstner bit and a template jig, which blows out the door stile or misaligns the drawer so it racks and destroys the slide. In South Florida’s humidity, a drawer box that measures right in morning cool can swell and bind by afternoon. If you’re matching a finish, Wellborn’s current “Silk” white isn’t the same as 2019 “Silk” white, a discrepancy that only shows under your kitchen’s LED strips. Do it right the first time or you’ll do it twice, and the second time always costs more. For anything involving cabinet box replacement, plumbing relocation, or electrical outlet rerouting inside the cabinet, call (844) 665-0162. We bring the jigs, the humidity-acclimated stock, and the patience to get the reveal consistent across a full bank.
FAQs
Wellborn cabinets in South Florida typically last 15-20 years in climate-controlled spaces, but drop to 10-14 years in unconditioned ADUs where humidity cycles stress the joinery. The Estate series with plywood construction outperforms Heritage in these conditions by a noticeable margin. Call (844) 665-0162 and we’ll assess whether your boxes are worth saving or if a strategic replacement makes more sense.
Sometimes. A dry or debris-clogged Blum Tandem slide can be cleaned with denatured alcohol and re-lubed with white lithium grease, which buys 12-18 months. But if the polymer slide body is cracked or the soft-close cylinder leaks hydraulic fluid, replacement is the only fix. We stock both OEM Blum and quality equivalent slides for same-day swap in most Wellborn configurations.
A single drawer or door swap takes 45-90 minutes. A full kitchen hardware refresh across 20-25 cabinets runs one to two days, including removal, disposal, installation, and adjustment. ADU jobs sometimes take longer due to tighter working clearances and coordination with active plumbing or electrical. We schedule to minimize your downtime.
We carry Blum and Salice hinge sets, Tandem and undermount slide pairs in standard lengths, and adjustable leg kits on every South Florida service vehicle. Finish-matched doors and drawer fronts come from our Miami-Dade warehouse, usually same-day for current Wellborn colors and 2-3 days for archived or special-order finishes. Call (844) 665-0162 to confirm availability for your specific series and color code.
