KraftMaid Home Additions & ADU: The Sunnyvale Owner’s Guide

KraftMaid cabinet systems installed in Sunnyvale home additions and ADUs typically run $45,000-$130,000 for the full build-out, with cabinet packages themselves ranging $4,000-$13,000 depending on series and linear footage. We stock KraftMaid-compatible hardware, drawer systems, and door fronts for same-day replacement on most orders placed by noon. Most Sunnyvale owners discover an issue when a drawer box separates at the dovetail joint after years of seasonal humidity swings, or when a soft-close hinge loses its damping after the fifth year of daily use.

Which KraftMaid Models This Applies To

KraftMaid organizes its product lines by construction type and price tier, and the parts are not interchangeable across all of them. The three series we encounter most in Sunnyvale additions and ADUs are the all-ply Vantage line, the furniture-board CoreGuard series, and the solid-wood Cherry or Maple collections. The Vantage drawer boxes use 5/8-inch plywood with dovetail joints; CoreGuard uses similar joinery but in a thermofoil-wrapped composite that expands differently in our dry Santa Clara Valley summers. To identify your series, pull a drawer fully out and check the back panel for a stamped date code and a two-letter series prefix. The hinge cup bore pattern is 35mm across all current lines, but the soft-close cartridge changed in 2019, so a post-2019 hinge will not seat correctly in a pre-2019 door bored to the earlier depth. We carry both generations on our truck, along with the older Blumotion clip-on cartridges that KraftMaid used before switching to the integrated hinge body. Aftermarket equivalents from Blum and Salice meet the same cycle-test standards; we specify which we are quoting and why.

Signs Your KraftMaid Home Additions & ADU Is Failing

• Drawer front sags or tilts when loaded. The side-mount roller bracket has cracked at the plastic boss, or the epoxy-coated steel slide has bent at the rear mounting tab. In Sunnyvale’s older Lakewood Village homes near Washington Park, we see this where original 2010-2015 installations used 75-pound-rated slides in pantry pull-outs now loaded with stand mixer attachments and bulk goods.
• Soft-close hinge slams in the last two inches. The hydraulic damping cartridge has leaked its silicone fluid, usually after five to seven years of heat cycling. South-facing ADU kitchens with minimal overhang see this two years sooner than north-facing units.
• Door finish peels at the stile-rail joint. Moisture has wicked through the end grain of the five-piece door, lifting the catalyzed varnish. This is cosmetic until the substrate swells; at that point the door will not close flat against the face frame.
• Lazy Susan shelf binds or detaches from the pivot. The polymer bearing ring has flattened under load, or the center shaft has worked loose from the cabinet floor. The correction is a new bearing set and a longer lag screw into the subfloor, not just a shelf swap.
• Under-cabinet LED flickers or sections go dark. The 24-volt driver is failing, or the solderless connector has oxidized in the humidity from a nearby dishwasher vent. We test driver output before replacing strips; the part is often the driver, not the diodes.

Replacement Cost & What’s Included

For a KraftMaid-equipped home addition or ADU in Sunnyvale, cabinet component replacement typically falls within the broader project range of $45,000-$130,000 for full construction, with individual part repairs running $200-$800 depending on scope. A drawer box rebuild with new 5/8-inch plywood sides, bottom, and Blum Tandem plus soft-close slides runs $280-$420 installed. Hinge replacement with adjustment and door realignment is $45-$85 per door. Lazy Susan hardware kits are $180-$320. What drives the range is access: a base cabinet in an open kitchen takes twenty minutes; the same repair in a tight ADU galley with the dishwasher in place takes ninety. Our quote lists material, labor, and any subcontractor scope separately. Under Clause 1 of the Haven Standard, that written price is fixed; no change proceeds without a signed change order. The 365-Day Done Right Promise covers the workmanship. We also source Cambria and Silestone countertops, plus Kohler fixtures, so a full ADU kitchen refresh pulls from one quote with honest numbers rather than inflated allowances.

DIY or Call Us?

There is no high-tension danger in cabinet hardware, but there is a cumulative frustration cost. An owner with a drill and a steady hand can swap a hinge or a slide; the catch is getting the three-axis alignment right so the door does not rub the face frame or the adjacent door. Drawer slide replacement requires removing the box, which in a full-extension soft-close system means releasing two locking tabs simultaneously while supporting forty pounds of plywood. Where DIY goes wrong is in the diagnosis: a sagging drawer is often a symptom of a settled cabinet floor or a twisted face frame, and new slides will fail again in six months. We offer a documented photo record on every visit, included as standard, so you see what we found before we quote the fix. Call (650) 405-3637 to schedule your free estimate.
