Wellborn Home Additions & ADU: The San Antonio Owner’s Guide
Wellborn home additions and ADU projects in San Antonio typically run $45,000 to $130,000 installed, depending on square footage, foundation work, and finish level. We stock Wellborn-compatible cabinetry and trim components on our trucks and can usually start your project within two to three weeks of the written estimate. Most San Antonio homeowners call us after realizing their existing space no longer works: the kitchen’s too tight, the in-laws are moving in, or a home office is now non-negotiable.
Wellborn cabinets are built in Alabama, but San Antonio’s heat and humidity cycles test every component. We see door warping, soft-close hinge failures, and drawer box separation more often in unconditioned spaces like garages and sunrooms. When you’re adding square footage to a home with existing Wellborn cabinets, matching the door style and finish matters more than matching the box construction, since San Antonio sun exposure fades finishes at different rates room to room.
Which Wellborn Models This Applies To
Wellborn runs three main cabinet lines that show up in San Antonio additions and ADUs: Estate, Premier, and Cabinetworks. Estate is the full-custom line with maple, cherry, and hickory options. Premier is the mid-tier line with plywood boxes and a shorter lead time. Cabinetworks is the value line, but it still uses the same door profiles as Premier, which matters when you’re matching an existing kitchen.
Here’s the compatibility gotcha most people miss: Wellborn changed their hinge boring pattern in 2019 on select Premier door styles. If your existing cabinets predate that, a new door won’t hang on the old hinge plate without a conversion bracket. We check the door stamp inside the cabinet box, usually a white label on the top hinge rail, before ordering anything. The other gotcha is finish code matching across product generations. Wellborn’s “Natural Hickory” from 2015 is not the same as today’s. Ordering by name alone gets you a visible mismatch. That’s why we always pull a door sample or take a physical chip match before we write the cabinet portion of the quote. OEM Wellborn doors cost 30 to 45 percent more than quality aftermarket equivalents, but if you’re matching an existing run, OEM is usually the right call. For a standalone ADU kitchenette where nothing has to match, aftermarket doors with upgraded Blum hardware can outperform OEM at a lower price.
Luca Romano grew up in East Los Angeles and learned the trade at Los Angeles Trade-Technical College before spending decades swinging hammers on real jobs across the Southwest. That background matters on additions: framing tolerances in a San Antonio summer are different from anywhere else, and getting the cabinet walls square before install is the difference between doors that close clean and doors that bind in August. Sawyer Remodel San Antonio is an independent service provider, not affiliated with Wellborn, but Wellborn cabinets are one of the primary lines we install and the brand the crew knows best. We also stock and install parts for KraftMaid, Cambria, and Silestone.

Signs Your Wellborn Home Additions & ADU Is Failing
- Doors that rub or won’t close clean in the summer. San Antonio humidity swells wood doors, and if the original install didn’t leave proper reveal gaps, the doors bind. This is a hinge adjustment and sometimes a light plane job, not a full replacement.
- Drawer boxes separating at the dovetail joints. We see this on Wellborn Premier boxes that have lived in unconditioned garage or patio spaces. The glue fails from heat cycling, and the box starts to rack. A new drawer box is cheaper than people expect.
- Soft-close hinges that slam instead of catch. The hydraulic damper inside the hinge wears out. Wellborn uses mostly Grass and Blum hardware, both of which sell replacement hinge sets that drop in without touching the door.
- Finish fading or peeling on sun-facing cabinet runs. Direct San Antonio sun through a west-facing window will fade any wood finish over a decade. If the doors feel chalky or the color has shifted, that’s UV damage, not a cleaning problem.
- Cabinet boxes pulling away from the wall. This is a structural warning, usually from a house settling or from an addition that wasn’t tied into the original slab properly. Get it checked before loading heavy stone countertops on top.

AfterReplacement Cost & What’s Included
A full home addition or ADU project in San Antonio runs $45,000 to $130,000, and the cabinet portion of that typically lands between $4,000 and $13,000 depending on line, finish, and count. A standalone ADU construction project runs $90,000 to $220,000 all-in. If you’re only refreshing existing Wellborn cabinets in a new addition, the cabinet part stays at the lower end. If you’re building an ADU kitchenette from scratch with full custom Wellborn Estate, it climbs.
| Project | San Antonio Price Range |
|---|---|
| Full home addition (Wellborn cabinetry included) | $45,000 – $130,000 |
| ADU construction (detached, with kitchenette) | $90,000 – $220,000 |
| Cabinet installation only | $4,000 – $13,000 |
| Garage conversion (with Wellborn cabinets) | $30,000 – $80,000 |
What drives the range on the high end: foundation work on San Antonio’s shifting clay soil, electrical panel upgrades for a new ADU, and whether you’re matching an existing Wellborn finish versus starting clean. Every quote includes a written line-item price before work starts, so the cabinet portion, the labor portion, and the finish portion are all separate numbers you can see. The 365-Day Done Right Promise covers the workmanship: if something isn’t done right, we make it right, in writing, on every project.
DIY or Call Us?
Framing an addition or plumbing an ADU is not a weekend project. That’s not gatekeeping. San Antonio’s permitting process alone will eat a month if you’re not set up for it, and the structural work needs to survive the clay soil shifts that crack slabs and rack door frames. What you can do safely: measure your existing cabinet doors, check the hinge stamp, and write down the finish code before you call anyone. That saves a trip and gets you an accurate quote faster.
What usually goes wrong on DIY: ordering doors by finish name and getting a mismatch, building cabinet boxes out of square, and under-sizing the electrical for a new ADU kitchenette. Those fixes cost more than hiring it right the first time. If you want the part matched, the cabinets installed, and the permit pulled, call (432) 547-6806. The craft comes first. Everything else follows.
FAQs
Wellborn boxes and doors last 20 to 30 years in climate-controlled San Antonio spaces, but hardware like hinges and drawer slides typically needs replacement at the 10 to 15 year mark. Unconditioned spaces cut that lifespan roughly in half. Call (432) 547-6806 for a cabinet-by-cabinet assessment, estimates are free.
Most Wellborn cabinet issues we see in San Antonio are repairable: hinge swaps, drawer box replacement, door re-hanging, and touch-up finishing are all cheaper than new cabinets. Full replacement only makes sense when the boxes are water-damaged or the finish is shot from UV exposure. We’ll give you the honest answer either way.
Cabinet installation in a new addition or ADU typically takes 2 to 4 days on-site once the boxes arrive, with lead time on ordered Wellborn parts running 3 to 6 weeks depending on the line and finish. We give you a written schedule before work starts and photo updates as the job moves.
We stock common Wellborn-compatible soft-close hinges, drawer slides, and touch-up kits on the truck, but door fronts and drawer boxes are ordered to match your existing finish code. That’s why we pull a physical sample before ordering anything with a finish attached.
