Wellborn Home Additions & ADU: The San Francisco Owner’s Guide
A Wellborn home addition or ADU project in San Francisco typically runs between $53,100 and $153,400, depending on square footage, foundation work, and whether you’re building up or out. We install and manage Wellborn cabinetry and finish materials as part of larger addition and ADU builds, and we stock common Wellborn replacement components for owners whose existing cabinetry, drawer hardware, or door fronts have failed. Most owners discover a problem the way you probably did: a drawer that won’t close square, a hinge that’s pulled loose from the cabinet face, or a door front that’s delaminated after years of San Francisco fog-season moisture.
Before you replace a single component, let’s identify what you’re actually dealing with. Wellborn makes several cabinet lines, and the mounting hardware, door profiles, and finish codes vary between them. We’ll walk you through it below.
Which Wellborn Models This Applies To
Wellborn Cabinet, Inc. builds three primary product tiers: Estate, Premier, and Select. The Estate series uses full plywood box construction and soft-close doors with 110-degree clip hinges. Premier and Select lines use a mix of plywood and engineered panels, and Select doors typically have 95-degree hinges with a different mounting plate. If you’re matching a replacement door, drawer face, or hinge, you’ll need to know which series you have. The label is usually on the inside of a drawer box, stamped or printed, or on the exposed cabinet side near the top corner.
Here’s the San Francisco gotcha that most owners don’t anticipate: homes in the Sunset and Richmond districts carry higher indoor humidity year-round than homes in, say, the Mission or Noe Valley. That’s not a Wellborn defect, it’s coastal fog. Wellborn doors with an MDF center panel are more susceptible to edge swelling than all-wood doors, and we see that pattern repeatedly in homes within half a mile of Ocean Beach. If your door panels are swelling and the original finish is MDF, the honest long-term fix is often a solid wood replacement door, not another MDF panel that will do the same thing in four or five years.
On OEM versus aftermarket: Wellborn’s own replacement doors come pre-finished and matched by the original order code, but lead time runs four to eight weeks. Quality aftermarket doors, machined by a local San Francisco cabinet shop to Wellborn’s dimensions, can arrive in under two weeks and often cost 20 – 30% less. We’ll give you pricing for both paths before you commit to anything. For hinges and drawer glides, we use Blum hardware, which is what Wellborn installs at the factory in most series, and we keep those on the truck.

Signs Your Wellborn Home Additions & ADU Is Failing
- Drawer won’t stay closed or hangs uneven. This almost always points to a worn-out undermount glide. Once the soft-close mechanism inside the glide fails, the drawer drifts back open or slams shut. The fix is a glide replacement, not a drawer adjustment.
- Hinge pulls loose from the cabinet face. The hinge itself is rarely the problem. The screw holes in the cabinet face have stripped, usually from years of opening force. We repair the face with a threaded insert and remount the hinge, which is stronger than the original.
- Door panel seams showing or veneer lifting. This is the fog belt problem again. When warm kitchen air meets cool cabinet faces near an exterior wall, the panels expand and contract. Wellborn doors with plywood center panels hold up. MDF panels eventually show it.
- Soft-close doesn’t soften anymore. That’s the damper inside the hinge worn out. On Wellborn Estate and Premier lines, the hinge is a clip-on Blum with a replaceable damper cartridge. On Select, the hinge gets swapped wholesale.
- Finish worn through at the toe kick or around frequent-use handles. If the cabinet boxes are otherwise sound, the honest fix is replacing the worn faces and hardware rather than the entire run. We match Wellborn finishes by code, not by eye, because direct daylight in a San Francisco kitchen shows every mismatch.

AfterReplacement Cost & What’s Included
An installed Wellborn cabinet door replacement in San Francisco runs $180 to $340 per door, depending on finish and whether it’s solid wood or MDF. Drawer glide replacement runs $120 to $210 per drawer, including the Blum hardware and the labor to pull and reset the drawer. Full hinge replacement across a typical ten-door kitchen runs $350 to $700. These prices are installed, with the written price given to you before we start, and they include the cleanup and a photo of the finished work before we leave. If you’re adding a Wellborn cabinet run as part of a larger home addition or ADU build, the cabinetry portion typically falls between $4,720 and $15,340 on top of the structural work.
The 365-Day Done Right Promise covers our parts installation: if a hinge we mounted comes loose or a drawer we set doesn’t ride square within the first year, we come back and make it right at no charge.
DIY or Call Us?
For a cabinet face or drawer glides, there’s no high-tension, electrical, or structural risk. Replacing a soft-close hinge or a drawer glide is work a careful homeowner can do with a Phillips screwdriver and a tape measure, and Blum glides come with mounting instructions that are actually legible. Where I’d stop and call us: any time you’re pulling more than one drawer face or door front at once, any time you’re matching a Wellborn finish, or any time you’ve already stripped a screw hole. Once a homeowner has put a longer screw through the back of a raised-panel door, the repair gets pricier than the original fix would have been.
If it’s the kind of thing where you’d rather hand it to someone who’s set hundreds of Wellborn drawers across San Francisco, call us at (831) 480-4497 and we’ll come look. The quote’s free and written down.
FAQs
The box construction typically lasts 25 to 40 years; the soft-close hardware and door faces are the parts that wear out first, usually in the 8 to 15 year range for everyday kitchens. Homes near the fog line can see door panel wear sooner. Call (831) 480-4497 and we’ll tell you honestly whether your cabinets are worth repairing or if replacement makes better sense.
Hinges, glides, and stripped mounting holes can be repaired with replacement hardware at a fraction of the cost of new cabinetry. Door panels with delamination or MDF swelling are usually better replaced than patched. We’ll give you both options with written pricing before you choose.
Most hinge and glide replacements take one visit, usually two to four hours for an average kitchen. Replacement doors ordered through Wellborn run four to eight weeks from order to install; local aftermarket doors typically run two weeks. Either way, the labor day is short and quiet.
We stock Blum soft-close hinges, drawer glides, and mounting plates on the truck, because those are what Wellborn uses in most series. Door fronts and panel-matched parts are ordered per job. If you’re not sure what you need, call (831) 480-4497 and describe the symptom; we’ll tell you what to check before we even book the visit.
