Wellborn Home Additions & ADU: The Orlando Owner’s Guide
A Wellborn home addition or ADU project in Orlando typically runs $45,000 to $130,000 installed, depending on square footage, foundation type, and the specific Wellborn cabinet and trim lines you choose. We install and finish Wellborn-compatible additions and accessory dwelling units, and we can source Wellborn cabinetry, trim, and hardware directly from recognized trade suppliers. Most Orlando owners reach this page while researching how to expand their existing footprint, or after discovering that a previous addition is failing at the roofline, the slab connection, or the interior finish line.
The honest truth is that an addition or ADU is not a single part that fails. It is a system: framing, sheathing, flashing, drywall, cabinet runs, and trim that all have to meet Florida code and hold up in Orlando humidity. When one piece goes wrong, you feel it across the whole space. Trevor Nash has spent enough time inside College Park bungalows and older Orlando homes to know that the original framing usually matters as much as the new work, and we price every project with that in mind: give you the number first, then pick up the tool.
Which Wellborn Models This Applies To
Wellborn manufactures three cabinet lines that matter for Orlando additions and ADUs, and each one has different compatibility points when you are matching existing work or starting fresh. The Wellborn Premier line offers full-overlay doors with standard 1/2-inch plywood sides and a birch or maple face frame, and it is the most common line we see in mid-range Orlando kitchen and bath additions. The Wellborn Estate line upgrades to 5/8-inch plywood sides, soft-close drawer guides, and taller wall cabinets, and it is a frequent choice for whole-home additions where clients want a step up in finish. The Wellborn Select line is the entry series, with 1/2-inch sides and fewer door profile options, and it shows up in a lot of garage conversions and rental ADUs where the budget matters more than the door style.
The identification detail that actually saves you money: Wellborn stamps its model or series code on an interior cabinet side or the bottom of a drawer box, usually a letter-plus-number combination like E366 or P248. If you are matching existing Wellborn cabinets in a failing addition, pull a drawer and photograph that code before you call anyone. The OEM versus aftermarket decision for Wellborn specifically comes down to door profile matching. Wellborn’s door shapes, like the recessed panel and the raised arch, have specific dimensions that generic replacement doors do not match cleanly, and a 1/16-inch difference in stile width is visible to the eye. We source Wellborn components directly, and we recommend OEM cabinet components any time you are matching existing work, while quality aftermarket hardware from Blum or Salice is a better value than Wellborn’s hardware upcharges.

Signs Your Wellborn Home Additions & ADU Is Failing
- Water staining at the ceiling-to-wall junction. In Orlando, a failed roof flashing or an unsealed chase penetration pulls moisture down the framing, and the first visible sign is usually a tan or rust-colored bloom where the addition’s ceiling meets the outer wall. This points to flashing work, not a paint issue.
- Doors or windows that stick or no longer latch. Florida slab movement, especially in sandy Orlando soil zones, can shift a poorly flashed or under-pinned addition enough to pinch a door jamb. If a Wellborn cabinet door is fine but the room’s entry door is binding, the slab, not the cabinetry, is the likely culprit.
- Floor slope you can feel. A 1/4-inch drop over four feet inside a new addition usually means the stem wall or slab was not tied correctly to the original structure. This is a structural symptom, not a cosmetic one.
- Cabinet face frames pulling apart or drawer glides sagging. Orlando humidity cycles expand and contract solid wood Wellborn face frames, and a poorly ventilated ADU makes this worse. Hairline cracks at the frame’s corner joints are the first sign of moisture cycling.
- Drywall cracking along the connection line. Where the original house meets the new addition, a vertical crack at the splice line usually means the two structures are settling at different rates. In Orlando’s older neighborhoods, this is common when someone added square footage without adequately tying the rooflines or the footer systems.

AfterReplacement Cost & What’s Included
A full Wellborn home addition in Orlando lands between $45,000 and $130,000 installed. The lower end covers smaller bump-outs or a partial garage conversion with Wellborn Select cabinets and standard finishes. The upper end includes ADU-scale projects with a full kitchen, Wellborn Estate cabinets, engineered slab work, and premium countertop materials like Silestone or Cambria. A standalone ADU often sits at $90,000 to $220,000 once you account for independent utilities, a separate HVAC run, and Orlando permitting. Every line item number we give you is written down before work starts, and the number on day one is the number on the invoice.
What drives the range: foundation type (slab-on-grade versus stem wall with piers), the linear feet of Wellborn cabinetry, whether we are tying into the existing HVAC or running a new mini-split for an ADU, and finish level. Our number always includes the parts, the labor, the permit coordination, and the cleanup. And every project carries the 365-Day Done Right Promise in writing: if something we built fails inside that window, we come back and make it right, no charge, no re-inspection fee.
| Project Scope | Typical Orlando Range |
|---|---|
| Small home addition (bump-out, single room) | $45,000 – $75,000 |
| Mid-size addition with kitchenette and Wellborn cabinets | $70,000 – $100,000 |
| Full ADU with kitchen, bath, separate utility runs | $90,000 – $220,000 |
| Garage conversion to living space | $30,000 – $80,000 |
DIY or Call Us?
You can safely check your Wellborn cabinet stamp, photograph the serial code, and measure the visible water staining or drywall crack before you call. That information helps us diagnose over the phone. What you should not DIY is any structural or frame modification to an addition, any roof-tie or flashing repair at height, or any electrical panel work for an ADU service feed. Those are dangerous enough that a wrong move causes serious injury or burns down a new space, and Florida code requires licensed work on structural and electrical penetrations anyway.
If the failure is cabinet-level, like a sagging Wellborn drawer glide or a pulled face frame, we can usually handle that in a single visit. If the slab or tie-in is moving, the conversation is bigger, and we will walk you through the actual scope before we ever hand you a number. Call (850) 427-6454 and we will schedule a walkthrough. The estimate is free.
FAQs
A properly flashed and structurally tied Wellborn addition in Orlando should last 50 to 80 years for the framing and 20 to 30 years for finish surfaces like drywall, paint, and cabinet hardware before normal replacement cycles kick in. The variable is moisture: an addition with poor flashing or bad ventilation will show real failure inside five to seven years in Florida’s humidity, while a correctly detailed one is durable. Call (850) 427-6454 if your addition is showing early aging, and we will tell you honestly whether it is a repair or a deeper problem.
Yes, in most cases we can isolate and repair one failing section, whether it is a roofline flashing issue, a shifting footer, or a cabinet run pulling away from the wall, without rebuilding the entire Orlando addition. The exception is when multiple systems are failing together, usually slab movement plus water intrusion plus finish cracking, at which point a partial repair becomes a band-aid. Call us at (850) 427-6454 for a written scope, and we will show you exactly where the repair line versus rebuild line sits.
A small addition or cabinet-level repair work can take two to four weeks, while a full ADU with kitchen, bath, and utility runs typically runs three to six months depending on Orlando permitting and material lead times for Wellborn cabinetry. We give you a real arrival window in writing before any work starts, because the Kingswell Way means showing up in the window we gave, not a standing excuse. Call (850) 427-6454 and we can talk through the realistic timeline for your specific project.
We source Wellborn cabinetry, trim, and components directly through recognized trade suppliers, and while we do not warehouse full Wellborn cabinet runs, we can often pull common hardware, drawer glides, and matching trim profiles faster than a retail order because of our supplier relationships. For full cabinet runs in an addition or ADU, expect the standard Wellborn lead time, which we quote in writing before you commit. Other brands we work with include KraftMaid, Cambria, and Silestone when the project calls for a different cabinet or countertop line.
If you have a Wellborn addition or ADU in Orlando that is failing, or you are pricing one from scratch, call (850) 427-6454 and we will schedule a free walkthrough.
