Wellborn Home Additions & ADU: The Pasadena Owner's Guide
If you have a Wellborn home addition or ADU in Pasadena that needs attention, we install and service Wellborn-compatible work with complete home additions typically running $45,000 – $130,000 and ADU construction at $90,000 – $220,000. Those ranges assume the work is done by a licensed contractor in Pasadena with the proper permits, and they include the cost of cabinetry, hardware, and finish work tied to the Wellborn product. Most homeowners find out something is failing in a Wellborn addition when the cabinet doors start binding, the finish shows moisture bloom near the edges, or the hardware can no longer hold a door straight.
Here is the honest version: a Wellborn addition or ADU is a system, not a single part. The failure usually shows up first in the cabinets, because that is the Wellborn component that gets opened, closed, bumped, and loaded every day. What you are actually fixing is often a hinge mount that has stripped, a drawer slide that has bent, or a door that has swollen just enough to stop closing cleanly. We stock the common Wellborn-compatible replacement parts on the truck, and the first step is matching what failed to the exact series and finish so the fix does not look like a patch job.
Which Wellborn Models This Applies To

Wellborn builds across several series lines, and the parts are not all interchangeable. The Premier, Estate, and Select series share core hinge and slide architecture, but the door profiles and finishes change by line. The fastest way to identify what you have is to open a cabinet door and look at the inside edge of the frame or the back of the drawer box. Wellborn stamps the series, the finish code, and often a date code on a small white label or a stamped aluminum tag, usually on the hinge side of the face frame or the underside of the drawer. If you cannot find a label, take a photo of the door edge profile and one of the hinge mount, and we can match it from the truck or from our supplier’s inventory instead of guessing.
One thing that catches people in Pasadena: Wellborn has changed hinge-mount drilling patterns over the years. An older Premier cabinet from the early 2000s often uses a 35mm cup hinge with a different overlay measurement than a current Wellborn build. You cannot just swap a new hinge onto an old door and expect the reveal to line up. We keep OEM Wellborn hardware and quality aftermarket equivalents in the truck for the common series, and we measure the overlay before anything gets ordered or installed. Elmstead Remodeling Pasadena is an independent contractor; we are not affiliated with Wellborn, but we have worked with their cabinets long enough to know which parts actually match.
You will also run into this with KraftMaid, Cambria, and Silestone work where the adjacent surfaces meet the Wellborn cabinetry. A countertop overhang that is not supported the same way, or a backsplash that traps moisture against the cabinet edge, is often what started the problem in the first place. We look at that during the estimate, not after the new part fails the same way.

Signs Your Wellborn Home Additions & ADU Is Failing
These are the symptoms we see most often on Wellborn additions and ADUs across Pasadena, from Bungalow Heaven to Hastings Ranch:
- Cabinet doors that will not stay closed or hang crooked. This is almost always a worn hinge or a stripped hinge-mount screw. The fix is usually a new hinge and a properly sized repair screw or dowel, not a whole door replacement.
- Drawers that drag, stick, or drop on one side. Wellborn drawer slides have a lifespan, and in a Pasadena ADU with uninsulated walls, the temperature swings shorten it. A bent or worn slide is a thirty-minute swap if we have the right length on the truck.
- Swollen or darkened cabinet edges near the sink, dishwasher, or exterior wall. Moisture is the quiet killer. In an addition or ADU, poor vapor control or a slow plumbing drip will wick into the cabinet box. The part is often repairable, but the water source has to be found and stopped first.
- Loose or sagging cabinet pulls and knobs. This seems minor until someone loads a drawer with pots and pulls the front off. It is usually a stripped screw hole in the door face or drawer front.
- Soft-close doors that now slam shut. The damper inside the hinge or slide has failed. It is a small part, but it is the difference between a cabinet that feels like a Wellborn and one that feels like a rental.

AfterReplacement Cost & What’s Included

A full Wellborn home addition in Pasadena runs $45,000 – $130,000. ADU construction runs $90,000 – $220,000. Those are project-level ranges. But if you are here because a specific part failed, the fix is far smaller: a hinge or slide replacement usually lands in a few hundred dollars installed, depending on how many cabinets are affected. A door or drawer front replacement goes up from there based on the series, the finish, and whether Wellborn still stocks that exact door profile.
Every quote from us is a written, line-item price before any work starts. You will see the part cost, the labor, and any finish matching needed, all separated. That is firm. We do not come back mid-job with a change order because the overlay measurement surprised us, because we measured it before we quoted it. The 365-Day Done Right Promise covers every repair and installation we complete: if it is not done right, we make it right. Graham Stein puts the written scope and the line-item price in front of a homeowner before a single drop cloth goes down. The price you see on paper is the price you pay at the end – no footnotes.
DIY or Call Us?
You can safely check a few things yourself: find the Wellborn label inside the cabinet to get the series and finish code, test each door and drawer to see which ones bind, and note whether the problem is worse on exterior walls. That information helps us show up with the right parts. What you should not do is start pulling doors off and drilling new hinge holes. Wellborn face frames are not forgiving. One wrong drill measurement and a $30 hinge fix becomes a $140 door or frame repair. If the failure is on a large or heavy door, or if it involves an electrical run inside an addition or ADU, call us. The risk of injury from a falling door or a hidden wire is real. Call (626) 714-2992 and we will match the part and do the swap cleanly, with drop cloths down and shoe covers at the door.
FAQs

Wellborn cabinet boxes and face frames can last 25 to 40 years in Pasadena if the structure stays dry and the hardware is replaced as it wears. The hinges and drawer slides are the parts that fail first, usually somewhere between 10 and 20 years, and they are designed to be replaced. Call (626) 714-2992 for an exact assessment of what is wearing in your addition.
Yes, in most cases. A stripped hinge mount, a worn slide, or a failed soft-close damper is a repair, not a replacement. We will tell you honestly if a door or drawer front is too far gone to save. Call (626) 714-2992 and we will give you the straight answer.
Most individual hinge or slide replacements take 30 to 60 minutes per unit once the part is matched. Finish-matched door or drawer front replacements take longer, since the part often has to be ordered from Wellborn’s current production. Call (626) 714-2992 and we will give you a timeline with your written quote.
We stock common Wellborn-compatible hinges, drawer slides, and soft-close dampers on the truck, and we can source series-specific door and drawer fronts directly from our supplier network. If you have the label from inside the cabinet, that speeds up the match. Call (626) 714-2992 and we will check the truck before you schedule anything.
