Wellborn Home Additions & ADU: The Miami Owner's Guide
If your Wellborn home addition or ADU is showing signs of structural strain, water intrusion, or failing cabinetry, you're in the right place. Penhallow Remodeling Miami installs and services Wellborn-compatible additions and accessory dwelling units throughout Miami, with full projects typically running $53,100–$153,400 depending on square footage, site work, and finish level. Most owners discover a problem the hard way: a cabinet face separating from its frame in the humidity, a roofline dipping where the addition ties into the original structure, or water staining along a seam that never quite sealed right. We stock Wellborn cabinet components and regularly source their full catalog, which means we can usually match your existing line without tearing out more than necessary.
Which Wellborn Models This Applies To
Wellborn builds cabinetry and built-in storage across several lines – Estate, Premier, Millennia, and the semi-custom Select series are the ones we see most often in Miami additions and ADUs. The compatibility gotcha most owners miss: Wellborn changed their hinge drilling pattern on some full-overlay door styles around 2018, so an older replacement door ordered by model name alone won't always hang right on a newer cabinet box, or vice versa. Check the inside of a drawer box for a stamped code and measure the hinge cup spacing before ordering – 35mm is standard but the bore position from the door edge differs between generations. For structural components tied to your addition, like window trim, built-in bench seating, or closet systems, we always recommend OEM Wellborn parts over aftermarket equivalents because their finish matching process accounts for the UV fade that Miami sun causes – a cheap aftermarket panel looks like exactly what it is inside six months.

Signs Your Wellborn Home Additions & ADU Is Failing
- Doors that stick or won't close flush: In Miami's humidity, MDF core doors absorb moisture and swell. This isn't a hinge adjustment problem – it's the first sign the door has started to fail at the hinge point and will eventually crack.
- Separation at the ceiling line: If your addition's crown molding or ceiling-to-wall joint has opened up visibly, the structure is settling more than it should. In Coconut Grove, where we regularly work on older homes, this often traces back to how the addition was tied into the original slab.
- Water staining along baseboards or under windows: Wellborn pieces used in additions are only as good as the flashing and sealing behind them. Once moisture gets into the wall cavity, the cabinet carcass wicks it up and starts to delaminate.
- Soft spots in cabinet floors under sinks: A slow supply-line drip drips for months before anyone notices. By the time the shelf bows, the bottom panel is usually shot and needs replacement, not drying out.
- Drawer slides that grind or tilt: The ball-bearing slides on Wellborn boxes hold up well, but salt air near the coast accelerates corrosion. You'll hear it before you see it – a grind instead of a glide.

AfterReplacement Cost & What's Included
For Wellborn-specific cabinetry and built-in replacement within a Miami home addition or ADU, our work typically falls between $4,720 and $15,340, while full addition and ADU projects run $53,100–$153,400 depending on scope. What drives the number: whether we're matching existing finishes (which costs less than people expect when we're working with Wellborn's current catalog) or replacing enough that it makes sense to reface or reorder a full run; whether site conditions require structural repair before cabinets can go back in; and whether your project is in a neighborhood like Coconut Grove where older homes require permits and inspections that add fixed costs. Every quote we write in Miami includes the parts, labor, haul-away, and the 365-Day Done Right Promise in writing – if something fails inside a year, we come back and fix it, no service call, no re-inspection fee. We don't do change orders unless you ask for one.
DIY or Call Us?
You can safely check a few things yourself: measure the hinge cup spacing, look for the stamped code inside a drawer box, and take photos of the failing area in good light. What we'd stop you from doing is any repair that involves the structure around those Wellborn pieces – tying into a roofline, pulling base cabinets that share a wall with plumbing, or removing load-bearing built-ins without a proper temp wall. Trevor Nash will tell you straight: some of the jobs in Coconut Grove looked simple on paper and turned into three-week structural corrections once we opened the wall. That honesty is cheaper than a callback and safer than a YouTube tutorial. If your addition or ADU is showing any of the signs above, call (850) 988-7559 and we'll come take a look – give you a number first, then pick up the tools.
FAQs
Wellborn cabinetry typically holds up 15 to 25 years in Miami's climate, but that assumes the addition was properly flashed, sealed, and ventilated from day one. Units exposed to uncontrolled humidity, slow leaks, or direct afternoon sun through unshaded windows fail sooner. Call (850) 988-7559 if you're seeing early failure signs – a free inspection now is cheaper than a full replacement later.
Yes, in most cases we can repair rather than replace – especially when the issue is hinge failure, drawer slides, or a single damaged door or panel. What we won't do is patch a water-damaged cabinet box and call it fixed; the core is compromised and it'll fail again. Call (850) 988-7559 and we'll give you an honest read on repair versus replacement.
Simple cabinet part replacement – doors, drawer fronts, slides, hinge retrofits – is usually done in a single visit of 2 to 4 hours once parts are in hand. Structural work within an addition or ADU takes longer, typically 3 to 8 weeks depending on permitting and site conditions. Call (850) 988-7559 for a timeline specific to your project.
We stock common Wellborn hinges, drawer slides, and cabinet mounting hardware on our service vehicles, and we order door and panel replacements directly from Wellborn's catalog with a typical lead time of 7 to 14 days in Miami. If you can share the code stamped inside your drawer box, we can confirm availability before we ever ring your doorbell. Call (850) 988-7559 with that code and we'll check it while you're on the phone.
