Wellborn Home Additions & ADU: The Los Angeles Owner's Guide
We install, service, and source parts for Wellborn cabinetry and millwork within home additions and ADU projects across Los Angeles, with typical installed project ranges running $53,100 to $153,400 depending on square footage, foundation work, and finish level. Most Los Angeles homeowners we meet discover this need the same way: a planned addition grows past what the existing kitchen or bath cabinetry can support, or a converted garage ADU needs a full cabinet run and the Wellborn line they priced years ago no longer fits the new floor plan. The part itself is rarely the failure point. What fails is the planning around it: the wrong cabinet depth, the wrong door swing against a new wall, or trim that was never ordered because nobody checked the elevation drawing.
If your Wellborn product is already on site and showing wear, or if you're mid-remodel and realizing the cabinet order doesn't match the new space, this page tells you what we stock, what we can match, and what an honest fix costs in Los Angeles right now.
Which Wellborn Models This Applies To
Wellborn builds cabinet lines in three broad tiers, and the compatibility questions change with each one. The Cabinet Collection (entry line) uses standard 12-inch and 15-inch depth wall cabinets, 24-inch base cabinets, and frameless overlay doors with limited modification. The Premiere Collection moves into full-overlay and inset options, and this is where we see the most ordering mistakes on Los Angeles additions: a homeowner orders a 27-inch deep pantry cabinet for a 24-inch base run, or a 42-inch wall cabinet for a wall that actually has 39 inches of clearance below a ceiling beam. The Estate Collection adds custom widths and specialty finishes, which means every replacement piece is order-specific, not off the rack.
Two checkable details that matter in Los Angeles specifically: Wellborn door hinges are primarily compact 35mm cup hinges with a 110-degree opening, so if a door is binding on a new corner cabinet, the hinge is usually not the issue – the face frame was installed out of square. And in Los Angeles coastal-adjacent zones, Wellborn's thermofoil and laminate lines hold up noticeably better than painted MDF doors, because the marine layer moisture cycles every morning in Santa Monica and Playa del Rey will, over five or six years, swell an MDF door's bottom edge if the backside was never sealed. We check the backside seal on every Wellborn door we service.
Mason Remodeling is an independent service provider. We are not affiliated with Wellborn, and we don't represent them. We work on their products because Los Angeles homes are full of them, and because we can order OEM replacement doors, drawer fronts, and trim directly through our material partnerships alongside KraftMaid, Cambria, and Silestone product lines.

Signs Your Wellborn Home Additions & ADU Is Failing
- Doors that won't stay closed or won't open fully. This usually points to a hinge plate that has pulled loose from the face frame, which happens when an addition settles in Los Angeles' expansive clay soils. The door is fine; the anchor behind it is not.
- Drawer fronts that sit visibly lower on one side. Wellborn drawer glides are side-mount undermount-style on most current lines, and a drift of even 1/8 inch means the glide clip has fractured or the drawer box has pulled away from the front.
- Trim or crown molding separating at the corner seams. In an ADU with a wall-mount HVAC unit cycling hot and cold, the wood expands and contracts and the miter joints open up. It looks like bad installation, but it's often just the wrong adhesive for the temperature swing.
- Soft-close doors slamming shut. The soft-close damper inside the hinge cup wears out. This is a $5 part on most Wellborn lines, and we stock it on the truck.
- A cabinet run that no longer lines up with a new countertop or new wall. When a Los Angeles addition shifts the kitchen footprint, the existing cabinets sometimes can't be reused at all, even with new doors. That's not a repair decision; it's a layout decision.

AfterReplacement Cost & What's Included
For Los Angeles home additions and ADU work that includes Wellborn cabinetry, plan on $53,100 to $153,400 as a full-project installed range. Within that, cabinet installation alone runs $4,720 to $15,340, countertop installation $2,360 to $7,670, and a kitchen remodel that includes Wellborn cabinets typically lands between $16,520 and $53,100. Smaller ADU or garage-conversion kitchen builds often fall toward the lower end of the full-project range, because the cabinet linear footage is shorter.
What drives the spread: linear feet of cabinetry, whether we're matching existing Wellborn finishes or starting fresh, the countertop material, whether the project needs an electrician and plumber pulled in for the ADU rough work, and whether Los Angeles permit drawings trigger structural changes. You'll get a written price before any work starts. Not a verbal range, not a rough number. A written price, on paper, including what we're ordering, what we're installing, and what it costs. If a repair or install fails within 365 days of completion, we return and make it right at no cost. That's our 365-Day Done Right Promise, and it applies to every Wellborn cabinet run, door replacement, and drawer repair we do in Los Angeles.
DIY or Call Us?
Some things a homeowner can safely do: check the hinge plate screws with a screwdriver to see if they're stripped, clean the drawer glides, and take photos of the Wellborn door label inside the cabinet so we can match the finish code before we even come out. Those steps save time and money.
The parts we'd rather you not touch yourself: anything involving a wall cabinet removal, any cabinet that holds a built-in microwave or wall oven, and any drawer box that requires unfastening from the cabinet face. A 30-inch wall cabinet loaded with dishware weighs more than an extension ladder and a homeowner combined, and when it comes down wrong, it comes down through the countertop below it. If your Wellborn piece involves overhead weight or built-in appliance support, call us at (803) 680-2547 and let us send someone who does this every week.
FAQs
Twenty to thirty years is a fair expectation for Wellborn cabinet boxes in Los Angeles, assuming no water damage and a proper install. Doors and drawer fronts typically show age after ten to fifteen years, especially sun-facing kitchen runs where the finish fades unevenly. Call (803) 680-2547 if you're unsure whether to replace doors or the whole run – we'll tell you straight.
Yes, in many cases. Hinge failures, delaminating edge banding, and stripped screws are all repairable. The cases where replacement is cheaper are cracked MDF panels and thermofoil that has yellowed across an entire run. We'll quote both options and give you the written price before any work starts.
A door or hinge replacement on a single cabinet is done in under two hours on site. A full cabinet run replacement inside an addition or ADU typically takes two to four working days, including demo, leveling, countertop templating if needed, and finish trim. Exact timing depends on whether we're matching existing Wellborn stock or ordering a non-stocked finish.
We carry Wellborn hinge clips, soft-close dampers, drawer glides, and touch-up kits in our Los Angeles trucks. Finish-matched doors, drawer fronts, and crown trim are order-triggered because Wellborn runs several hundred finish codes, and guessing a finish by photo is how homeowners end up with a door that's one shade off under kitchen lighting. We match it in person, order it once, and install it when it lands. For an exact quote on any of this work, call (803) 680-2547 – estimates are free, and you'll know who's coming before we get there. Know who's coming, know what it costs, know it's backed up – everything else is just noise.
If your Wellborn project is part of a larger Los Angeles home addition or ADU, we'll walk the entire scope with you before you commit to anything. We'll verify what's salvageable, what needs replacement, and what the full job costs in writing. Call (803) 680-2547 to schedule a free estimate, or to talk through what you're seeing with your Wellborn cabinets right now.
