Wellborn Home Additions & ADU: The Houston Owner’s Guide
We install and build Wellborn-compatible home additions and ADUs across Houston with a typical project range of $45,000–$130,000, depending on square footage, foundation work, and the Wellborn cabinet line you choose. Most homeowners reach out after realizing their existing space no longer works – a kitchen that crowds every holiday, a garage conversion that never got permitted, or an aging in-law suite with cabinetry that’s starting to sag at the seams.
The most common discovery path we see: a homeowner pulls a drawer and the glide separates from the cabinet box, or a corner cabinet door won’t close square because the box has shifted on an unlevel Houston slab. That’s usually the moment a “small repair” turns into a conversation about whether the room is worth saving at all. We’ll tell you straight if it is – and straight what it costs if it isn’t.
Which Wellborn Models This Applies To
Wellborn builds cabinetry across several lines – Estate, Premier, and Cabinetworks – and the home additions and ADUs we build around them need to match your existing line, not just the door style. The biggest compatibility gotcha we see in Houston: Wellborn offers both framed and frameless construction, and the hinge and drawer hardware are not interchangeable between the two. If you’re adding a second kitchen in an ADU and want it to match the main house, we need the original order number or a photo of the label inside a drawer box. That label carries the cabinet line, finish code, and door profile – it’s the fastest way to get a true match rather than a close-enough substitute.
For OEM versus aftermarket, we use Wellborn factory components whenever the existing line is still in production. For discontinued finishes, we source quality aftermarket doors and drawer fronts that are color-matched under natural light, not just under a shop lamp. Houston humidity will highlight a finish mismatch by August. We’d rather show you the difference in March than have you notice it in September.

Signs Your Wellborn Home Additions & ADU Is Failing
- Drawer glides separate from the cabinet box. The factory fasteners have sheared or the box has absorbed enough moisture to soften the screw holes. This is repairable if the box is still square; if the sides are bowed, the cabinet is done.
- Doors won’t close square. On a Houston slab, that usually means the floor has settled and the cabinet run is out of level front-to-back. Shimming helps short-term; a proper fix addresses the cabinet installation, not the hinge.
- Visible separation at the ceiling or wall corners. That’s framing movement from expansive clay soil, which we know well from Meyerland to the Energy Corridor. Cracks at the corner of an addition are often cosmetic, but repeated widening means the pier-and-beam or slab is moving.
- Soft spots in flooring near plumbing walls. In an addition or ADU, this points to a supply line leak inside the wall or under a slab. By the time you feel it, the subfloor is wicking water and the cabinet bases nearby are next.
- Musty smell in closed cabinets. That’s not a cleaning problem; that’s a moisture problem. Houston’s humidity finds every unsealed penetration in an addition envelope. We trace it to the source before replacing cabinetry – otherwise you’re just re-papering over a leak.

AfterReplacement Cost & What’s Included
For a full home addition in Houston built around Wellborn cabinetry, expect $45,000–$130,000. A smaller bump-out or single-room addition with a modest cabinet run lands closer to the bottom of that range. A full ADU with its own kitchen, bath, and separate utility connections runs between $90,000 and $220,000, depending on foundation type, trenching distances, and the cabinet package you select.
Everything is priced on a written line-item quote before any work starts. That number includes the Wellborn cabinetry, countertops, hardware, labor, waste removal, and permit fees if we’re the contractor of record. If something changes mid-project, we put the change in writing before we do the work – you’ll never see a surprise number at the end. Our 365-Day Done Right Promise backs every part of the installation: if something fails inside that year, we come back and fix it at no charge.
Key Takeaways
- Houston home additions: $45,000–$130,000; ADUs: $90,000–$220,000.
- Wellborn framed and frameless lines use different hardware – match before ordering.
- Written price up front, written guarantee on every project, 365-Day Done Right Promise.
- Soil movement, not the cabinetry, causes most “cabinet failure” we see in Houston.

DIY or Call Us?
You can safely check a few things: look for the label inside a drawer box, take a level to your cabinet run, and note whether doors bind only in the summer or year-round. That information helps us quote accurately over the phone.
What you shouldn’t do is pull cabinets off walls you think are load-bearing, alter framing, or open up a wall to trace a leak without knowing what’s behind it. We’ve seen a DIY cabinet pull in a Houston addition expose live wiring the owner didn’t know was there. Not worth it. Electricity, gas lines, and structural framing belong to a licensed contractor with the right trade knowledge. Call (254) 527-5340 and we’ll walk you through what you’re seeing before anyone picks up a tool.
FAQs
Wellborn cabinetry in a climate-controlled Houston addition should last 15–25 years with normal use. The lifespan drops sharply, closer to 10–12 years, if the space isn’t properly insulated and the cabinet boxes sit against an exterior wall that sweats in Houston’s summer humidity. Call (254) 527-5340 and we’ll come look at your space and give you an honest read on what’s left in it.
Yes, in most cases we can repair or replace individual cabinet boxes, drawer glides, and door hinges while keeping the existing Wellborn doors and face frames intact. The catch is matching finishes on older or discontinued lines. We’ll show you the match under natural light before we commit. If the cabinet box itself is compromised by moisture or framing movement, repair isn’t worth your money – replacing the affected section is.
A single-room cabinet replacement in an existing Houston addition takes 2–4 days once the new Wellborn components arrive. A full home addition or ADU runs 8–16 weeks depending on foundation, framing, and the city of Houston permit cycle. We give you a written timeline with the quote, and we hit it or we tell you why not before you have to ask.
We keep common Wellborn hinge, glide, and drawer-box components on hand for a same-day fix on the most common failures we see across Houston. For finished door fronts, drawer fronts, or a full cabinet run, we order directly through Wellborn’s distribution network and schedule the installation once everything is on site and inspected. We won’t start a job with half the parts missing.
Give me the straight story on what you need, and I’ll give you the straight number on what it costs.
