KraftMaid Home Additions & ADU Nationwide

KraftMaid Home Additions & ADU: The Palo Alto Owner’s Guide

KraftMaid cabinet systems installed in Palo Alto home additions and ADUs typically run $45,000-$130,000 for the full project, with KraftMaid cabinet packages themselves ranging from $4,000-$13,000 installed depending on series and square footage. We stock KraftMaid-compatible hardware, drawer boxes, and door fronts for same-day replacement on most current and recently discontinued lines. Most Palo Alto homeowners discover their KraftMaid components need attention during a room expansion or ADU conversion, when existing cabinets must integrate with new square footage or when moisture from a newly enclosed space warps drawer boxes that were never designed for that environment.

Which KraftMaid Models This Applies To

KraftMaid organizes its product lines by construction type and price tier, and the parts you need for a Palo Alto home addition or ADU depend on which system you’re extending. The All-Plywood Construction series, Duracraft semi-custom line, and the entry-level Vantage series each use different hinge plates, drawer-slide brackets, and door-bore patterns. Check the interior edge of your cabinet box for a white paper label with a six-digit SKU and a two-letter plant code, or measure the hinge cup diameter, 35mm for modern Blum-compatible KraftMaid hardware or 26mm for older Grass-style mounts.

OEM KraftMaid parts ship from their Middlefield, Ohio facility with a 2-3 week lead time, which is why we stock Blum Tandem Plus drawer slides, Salice hinge assemblies, and 3/4-inch pre-finished plywood panels cut to KraftMaid’s standard depths on our Palo Alto truck. For discontinued lines like the 2015-2019 CoreGuard polymer sink base series, aftermarket equivalents from Rev-A-Shelf or Häfele often fit better than waiting on limited OEM stock. The gotcha: KraftMaid’s square-recess door screws are not standard Phillips, so mixing hardware from a big-box store usually strips the heads. We carry the correct #2 square-drive bits and keep them on every crew bag.

Signs Your KraftMaid Home Additions & ADU Is Failing

• Drawer fronts sag or bind when the humidity shifts. Palo Alto’s marine layer pushes moisture into unconditioned ADU spaces, and KraftMaid’s standard particleboard drawer boxes, especially in pre-2018 units, swell at the bottom corners. The Tandem slide then rides cockeyed in the cavity. We replace with solid birch boxes and Blum undermount hardware rated for 75-pound dynamic load.
• Door gaps widen at the top or bottom seasonally. This usually means the 3-cam adjustable hinge has cracked its plastic boss in the door, a known issue on KraftMaid’s heavier 3/4-inch HDF door styles. The door weight over-torques the cam during daily thermal expansion. We install steel-reinforced boss replacements that don’t crack.
• Sink base floor shows black staining or soft spots. KraftMaid’s CoreGuard polymer liner was supposed to solve this, but the adhesive seam at the back wall often fails first in ADUs where the plumbing wall isn’t fully insulated yet. We pull the base, sister in a pressure-treated plywood floor, and re-line with a continuous sheet.
• Lazy Susan or corner unit hangs or detaches. The kidney-shaped polymer trays in KraftMaid’s standard corner units use a center pole with a plastic telescoping collar. After five years of loading, the collar ovalizes and the tray drops. We stock the heavy-duty metal replacement pole and bearing set.
• Finished end panels bubble or delaminate near new construction. ADU projects in Palo Alto often leave dust and drywall compound on existing cabinets during the rough phase. The alkaline residue attacks the thermofoil or polyester finish. We match the original color code, printed on the back of most KraftMaid doors, and replace with real plywood panels rather than re-laminating over damage.

Replacement Cost & What’s Included

What drives the range: finish grade, door style complexity, and whether we’re matching existing or starting fresh. A White Thermofoil replacement is straightforward; Cherry Natural with a vintage glaze requires a finish sample and 10-14 day shop time. Under Clause 1 of the Haven Standard, your written quote lists every cabinet, every hardware count, and every labor line before we order. No change proceeds without a signed change order, which is how we’ve kept projects within a few percent of the agreed number across 4,000-plus jobs since 2007.

DIY or Call Us?

There’s safe checking, and then there’s the point where you need a second pair of hands and the right truck stock.

What you can do: confirm the SKU on your cabinet label, photograph the hinge cup and slide bracket, and measure the opening width and depth. Email us the photos. We’ll cross-reference against KraftMaid’s current and archived specs and tell you whether the part is on our Palo Alto truck or needs to come from Ohio.

Where DIY goes wrong: adjusting a loaded Blum Tandem slide without releasing the locking lever snaps the nylon retaining clip, and the drawer crashes. Removing a thermofoil door to sand and repaint it destroys the vacuum-bonded edge. And anything involving a sink base floor, you’re working around plumbing stub-outs with a 4-inch clearance, which means cutting by feel. We’ve got the right oscillating multi-tool, the right vacuum attachment, and the right replacement panel already sealed on the edges. Call (650) 446-9092 and we’ll schedule a look. Estimates are free, and we bring the photo record so you see what we found before we talk about fixing it.
